For a brighter, whiter smile that you’ll love, please consult with Dr. Grupe to determine if whitening is the right treatment option. The CDA advises that, While there are several over-the-counter (OTC) whitening products that claim to whiten the teeth, it is best to complete the whitening process under the guidance of a dentist. In some instances, whitening would not be recommended, and Dr. Grupe will be able to advise you if your teeth and gums are healthy enough for whitening to be safe and effective. Also, as cosmetic products, over-the-counter whitening agents are not regulated and do not undergo the same governmental oversight as medical devices or drugs do.

Teeth whitening procedures are used to brighten the appearance of a patient’s smile.  Professional teeth whitening services can be performed in an office setting or prescribed for take-home use.  In many cases, simply whitening your teeth can make huge improvements in your smile.  Please ask us Dr. Grupe about what would be the best options for you on your next visit!

Did you know…

that the teeth naturally darken as we age? Furthermore, certain foods, beverages, medications and habits can contribute to a darker, yellowed, or stained smile. However, it is possible to erase years of stains in a single professional whitening session and sustain those results for many years with proper maintenance. According to the American Academy of Cosmetic Dentistry, professional whitening is best maintained by a combination of good oral care and take-home whitening treatments as recommended by Dr. Grupe.

Frequently Asked Questions

What does whitening involve?

Both in-office and at-home whitening options are available at our practice.  The in-office procedures use stronger whitening agents and produce the quickest results. The at-home option takes longer to complete, generally several days to a couple weeks.

Am I a Candidate for Teeth Whitening?

Yes, if you are experiencing discoloration but otherwise have healthy teeth and gums. Some patients, such as those who are pregnant or sensitive to whitening agents, may not be candidates for professional whitening.

What Should I Expect When I Get My Teeth Whitened at the Office?

The in-office teeth whitening process takes an hour to complete. Dr. Grupe begins by protecting the gums before applying a whitening gel to the surface of the teeth. The product will then be activated and left on the teeth for several minutes.  This process is then repeated up to five times until desired results are achieved.   The results will vary according to the natural shade of the teeth and degree of discoloration, but it is normal for patients to experience a lightening of several shades in a single visit.

What Should I Expect When I Get My Teeth Whitened at Home?

The at-home option takes longer to complete, generally several days to a couple weeks. For the at-home method, Dr. Grupe will take an impression of your mouth and create a custom made tray to hold the whitening solution. Dr. Grupe will instruct you as to the proper procedure for completing the whitening process.

What Type of Post-Treatment Care is Required After Having My Teeth Whitened?

The very latest pharmacological improvements to in-office bleaching solution is now able to avoid any post treatment tooth sensitivity.  Post treatment sensitivity used to be severe and was a deterent for Dr. Grupe to recommend to his patients.  We are now offering in-office bleaching with virtually no post treatment sensitivity.  It has become very popular in our office.

For at-home whitening post-treatment care, there may be sensitivity to be expected and avoiding consuming highly pigmented beverages is also advisable during the one to two weeks of treatment.


Patients are able to achieve an optimal smile through the vast array of cosmetic dental procedures available at NEWPORT IRVINE DENTAL.  These procedures include teeth whitening, smile design, porcelain crowns & veneers, enamel shaping, clear braces, and dental implants.  When you consult with Dr. Grupe he will gather information to determine what your wants and needs are, and make his professional recommendation so that you can make the right decision that’s best for you!



Frequently Asked Questions

What is bonding?

Bonding involves applying a tooth-colored composite resin to the surface of chipped, broken or discolored teeth.  The composite resin can also fill in gaps between the teeth and protect root surfaces that are exposed from the unwanted effects of gum recession. The entire procedure is virtually painless and is usually completed in one visit.  In some instances, complex cases may require several appointments.

What are porcelain crowns?

Porcelain crown technology has evolved to a state that can virtually duplicate the beautiful appearance of natural enamel.  It is one of our most important tools for creating, restoring or enhancing your appearance.  Dr. Grupe will be happy to share with you the possibilities that exist for improving your smile.

What are porcelain veneers?

Porcelain veneers are thin, custom-made, tooth-colored shells that cover the front of the teeth.   The process of applying veneers usually involves two visits.

What is enamel shaping?

If your teeth are very slightly overcrowded or uneven, or have very tiny chipped edges they can be slightly contoured in a procedure called enamel shaping or cosmetic recontouring. For instance, a tooth looks much longer than the rest, some enamel can be removed and your tooth can be reshaped. The process is usually quick and painless.

 What are dental implants?

A lost tooth or teeth can be replaced with dental implants.  A dental implant can be regarded as an  artificial root that is attached directly into the jawbone.  They can be expensive and the entire process can be quite lengthy.  Implants provide a definite benefit for very specific dental conditions.  A consultation with Dr. Grupe can provide valuable information as to when an implant would be to your best advantage.


TMJ Treatment and Night Guards

TMJ refers to the temporomandibular joint, which is the bone structure, muscles and connective tissues that surround the jaw and control chewing. When patients experience disorders of this joint, they are said to have a temporomandibular joint disorder, or TMD. Symptoms of TMD include pain and tenderness near the jaw, as well as popping or clicking in the joint when speaking or chewing. There are many ways of treating TMJ disorders at Newport-Irvine Dental, ranging from non-invasive therapy and bite splints to injections or surgery. Left untreated, however, TMJ disorders can lead to headaches, muscle pain, malocclusion and tooth damage from grinding or clenching.  If you are currently experiencing any of these symtom, please call to schedule an appointment so that Dr. Grupe can help alleviate your pain.

TMJ Treatment

Did you know…

TMD alone is not a disorder, but instead a collection of disorders that affect the temporomandibular joint. It is the second most common pain-causing musculoskeletal condition in the U.S. According to the U.S. National Institute of Dental and Craniofacial Research, as many as 12 percent of Americans may suffer from some type of TMD, with women twice as likely to be affected than men. Despite the prevalence and wide availability of treatment, one out every three people with TMD fails to seek treatment.

Frequently Asked Questions

What is bruxism?

The CDA affirms that bruxism is, “Also known as teeth grinding. A lot of people suffer from this disorder unknowingly, as it usually occurs during sleep. And, unless the constant racket of the grinding is keeping someone else awake, the patient may not think that the sore jaw, restless sleep and general fatigue are symptoms of bruxism. Left untreated, it could lead to painful or loose teeth, or teeth that are literally ground down, leaving worn surfaces or fractured enamel. While Dr. Grupe can usually detect the telltale signs of wear on the teeth, if the patient suspects a grinding problem, be sure to mention it at the next visit. The patient and Dr. Grupe can then determine the cause and appropriate treatment for the patient’s problem.”

What causes bruxism, or teeth grinding?

According to the CDA, “A major cause of bruxism is stress. Dr. Grupe may recommend that the patient wear a plastic mouth guard at night to prevent grinding. The custom-made guard keeps the upper and lower teeth from coming together, helping to relax the jaw muscles, and making it impossible for the patient to grind the teeth against one another. Dr. Grupe may also prescribe muscle relaxants or anti-inflammatory medications.”

How do I treat bruxism?

“Since no specific, definitive treatment capable of canceling bruxism is yet available, all efforts are directed towards the prevention of bruxism’s destructive effects. Occlusal splints, also known as night guards, are undoubtedly the means more commonly used to preserve dental structures” (Daniel A. Paesani, “Bruxism: Treatment and Practice” pg. 360).

What is the advantage of having an occlusal splint, or night guard?

“The major advantage of splints is their ability to protect teeth- both natural teeth and prosthetic restorations, including implants. Splints not only prevent wear, they also prevent potential fractures in teeth, restorations, prostheses, and implants.” In addition, night guards, “Eliminate the pain that patients commonly complain of on waking. Splints also help alleviate fatigue and morning muscle pain” (Paesani, 361).




How do I know if Newport-Irvine TMJ treatment is right for me?

You will first need to be formally examined and diagnosed with TMJ disorder. Dr. Grupe will evaluate the extent of the condition and determine what course of treatment is the most optimal. Usually, the initial approach involves conservative treatments, such as self-care, physical therapy and bite guards. Medications may also be used to relax the jaw or relieve pain. Patients who do not respond to conservative treatments may be considered for surgery or joint injections.

What should I expect if I undergo treatment for TMJ

Newport-Irvine TMJ treatment varies from patient to patient. The patient may be asked to adopt certain lifestyle changes to help facilitate rehabilitation in the jaw. For example, avoiding sudden jaw movements such as yelling or yawning. Also, sleeping on the back and reducing stress levels.

Will I need to follow any special post-care instructions while being treated for TMJ?

Post-treatment care instructions will vary according to the type of treatment the patient receives. In the event of an aggressive treatment, such as surgery, the patient may be temporarily subject to an all-liquid diet. Applying ice to the face will minimize swelling and keep the surgical site clean and dry.

Newport-Irvine Dental Sealants

In addition to regular routine brushing and flossing, Dr. Grupe can apply a coat of plastic material – called a sealant- on the top or biting surfaces of the back teeth. This plastic coating creates a barrier on the teeth and seals out the decay-causing bacteria that live in plaque, prolonging the life & vitality of the teeth.

Dental sealants are very thin coatings used to fill in deep grooves and pits in teeth that can harbor bacteria. Sealants are applied to healthy chewing surfaces of the teeth to prevent decay and cavities – especially among children. According to the Centers for Disease Control, tooth decay affects more than half of children ages 6 – 8, and even more older children and teens. By applying sealants, families can prevent decay and save on the costs associated with having to fill cavities. If you plan to get dental sealants at Newport-Irvine Dental, the CDC recommends doing so shortly after the molars have erupted from the gums – usually beginning around age 6 with the eruption of the first permanent molars.

Dental Sealants

Did you know…

  • Dental sealants can last up to 10 years in the average patient.
  • Many Newport-Irvine parents choose sealants for their children because it is more affordable and less invasive to prevent cavities than it is to treat irreversible dental decay.
  • Sealants are white or clear in color, making them virtually invisible when talking, smiling or eating.
  • Dental sealants cover approximately 90 percent of the tooth structure and are 100 percent effective when fully preserved on the teeth.

Frequently Asked Questions

What is plaque and why does it cause cavities?

According to the CDA, “The food and liquids the patient eats and drinks combine with bacteria to produce a sticky film called plaque. Plaque attaches on and in between teeth, where it starts to eat away at the tooth enamel. If plaque is not removed regularly by brushing and flossing the teeth, it can produce acids that will create pits or holes (cavities) in the tooth. This is tooth decay.”

How can sealants help prevent cavities?

The CDA advises that the prevention of cavities begins with, “Applying a thin plastic coating to the teeth which makes it harder for the plaque to stick to the tiny groves on the biting surfaces of the back teeth – protecting the tooth surface and reducing the risk of forming cavities.”

Is it difficult to apply sealants?

The procedure is fast and free of pain. Sealants are known to last for several years. At regular check-ups, Dr. Grupe will verify the condition of the patient’s sealants.

Who should get sealants?

According to the CDA, “Sealants are most effective in reducing cavities in children with newly formed permanent teeth. In fact, all children should have their molars (back teeth) evaluated for sealants soon after they erupt. For most children, this occurs approximately at ages 6 and 12. Sealants can also be useful in cutting down formation of decay in adult teeth, as well. An application of sealants is a preventative need for fillings and more expensive treatments that may be required to repair the damage from cavities, so sealants can save the patient money.”


How do I know if Newport-Irvine dental sealants are right for my child?

Sealants are an option if the child has molar teeth that are healthy and free of decay. Schedule a dental consultation with Dr. Grupe for a complete examination to determine if dental sealants could be a preventative health solution for your children.

What should I expect when my child gets dental sealants?

The child will not experience any pain when sealants are placed. There is minimal, gentle drilling to remove bacteria from the grooves where decay begins. This procedure ensures that the sealent will successfully adhere to the enamel leaving the entire tooth intact and safe from decay. After preparing the grooves, the tooth will be thoroughly cleaned and treated with a special gel before the sealant is painted on and cured.

Are there any special care instructions to follow after the sealants are placed?

Normal eating habits can be resumed immediately after dental sealants are applied.

Newport-Irvine Root Canals

Root canals are valuable dental procedures used to treat and preserve teeth with badly infected roots. The pulp is the live portion of the tooth that extends into the root and contains nerve endings and tissues. When it becomes infected, patients can experience pain, swelling and even total tooth loss unless treated. Root canals remove the damaged parts of the tooth and infected root. In some cases, an antibiotic is prescribed to help prevent further infection within the tooth. The organic portion of the tooth that remains may be restored using a cap or crown that provides a natural appearance and normal tooth function.

 Many patients associate root canals with pain and discomfort…

But local anesthetics and advancements in modern dentistry have made root canals highly tolerable procedures that are often no less comfortable than getting a standard filling. Upon completion, a restored tooth that has undergone a root canal will blend in with surrounding teeth – virtually undetectable to the average eye. More than 9 out of 10 Newport-Irvine root canal procedures are successful, and most treatments last many years or even a lifetime.

Frequently Asked Questions

Am I a candidate for a Newport-Irvine root canal?

Yes, in the event that decay or damage has allowed bacteria to infect the pulp inside your tooth. A root canal could also be the right treatment if the patient wants to preserve as much of the natural tooth as possible instead of extracting both the healthy and diseased portions of your tooth. For more information about Newport-Irvine root canals, schedule a dental exam and consultation with Dr. Grupe.

What should I expect during my root canal treatment?

If undergoing a root canal, the first step in the procedure will involve a local anesthetic. Once the tooth root is numb, the diseased portion of the tooth pulp will be removed and potentially treated for bacterial infection. The tooth will then be sealed and filled before being restored with a crown.  Dr. Grupe clinical expertise will ensure you have minimal discomfort during your procedure, many of his patients often fall asleep during their root canal procedure.

What type of post-treatment care is required after a root canal?

It is normal for teeth to become inflamed after a root canal, potentially causing sensitivity for the first several days following treatment. However, normal brushing and flossing habits can be resumed immediately after treatment and restoration is complete.

Restoritive Care: Inlays and Onlays

Inlays and onlays are dental restorations that are more extensive than dental fillings but less than caps and crowns. They are typically formed in a dental lab and are made of gold, porcelain or resin depending on the patient’s needs and aesthetic goals. An inlay refers to a restoration that is formed to fit the center of a tooth, whereas an onlay refers to a restoration that encompasses at least one cusp of the tooth. Both inlays and onlays are bonded to the surface of damaged teeth and matched to the color of the surrounding teeth.

Inlays and Onlays

Did you know…

that Newport-Irvine inlays and onlays can serve as alternative treatments to dental crowns when you have a broken or damaged tooth? When fillings are not enough to adequately repair a tooth, an inlay or onlay can be custom-created to fit securely onto the tooth’s surface. Depending on the materials used, the restoration can be created to appear natural and will have the same function of an organic tooth. Inlays and onlays have extremely high success rates and because they are custom made for each patient, most last longer than traditional fillings.

Frequently Asked Questions

Am I a candidate for an inlay or onlay?

You could be a candidate for an inlay or onlay in Newport-Irvine if you have moderate tooth damage or decay and are in search of an alternative restoration option to a crown or cap. Schedule a dental consultation for a complete examination and to find out if an inlay or onlay is right for you.

What should I expect when I get my Irvine inlay or onlay restoration?

Your inlay or onlay restoration will be completed over multiple dental treatments. First, your tooth will be prepared for treatment, and an impression will be taken to serve as a mold for your new restoration. You may be fitted with a temporary restoration while your permanent inlay or onlay is fabricated. Once completed, you will return to have the temporary restoration removed and the permanent one bonded to the surface of the teeth.

Do I need to follow any post-treatment care guidelines?

Special care needs to be given to your teeth while temporary restorations are in place. It is important to avoid sticky or hard foods that could cause significant damage to temporaries. Once you receive your permanent inlay or onlay, you can resume normal eating, brushing and flossing habits.


Implants have been around for many years and have gained wider and wider acceptance over time as they have proved a successful method for replacing missing teeth. They offer a way to have artificial teeth that look natural and feel secure. The implant itself, often made of titanium, is used like an artificial root to support a false tooth or teeth.  A dental surgeon places the implant in a hole made in the jawbone.  Once the implant is secure, it becomes an artificial root and can be used to secure a prosthetic device, such as a crown or bridge, above the gum.  Implants can also be used in conjunction with a removable or a full denture to create a more secure and stable base for the denture.


Did you know…

that approximately 30 million people live with no natural teeth in one or both jaws? But more and more dental patients are opting for dental implants as a means of tooth replacement. The American Academy of Implant Dentistry reports that 3 million people currently have dental implants – a number that is rapidly growing by about 500,000 per year. Modern titanium implants were first developed in the 1950’s, but archeologists have determined that ancient Egyptians and Mayans were the first cultures to implant artificial teeth.

Frequently Asked Questions

Why implants?

The CDA advises that, “Implants have some advantages over removable dentures. Because removable dentures are not permanently fixed in place, they can move around when the patient eats and speaks. Additionally, over time the bone that supports the denture changes and shrinks making it increasingly difficult to support a denture comfortably. Implants also have some advantages over fixed bridges, especially when the teeth adjacent to the missing tooth or teeth are healthy. In order to create a fixed bridge, Dr. Grupe must usually place crowns on these adjacent teeth- as they are the support for the replacement tooth or teeth. If these teeth are free form decay and existing restorations, you may prefer to leave them in their natural state, rather than alter them to hold the necessary supporting restorations. Implants replace the missing tooth or teeth while leaving all adjacent teeth unaltered.”

Are dental implants right for me?

You may qualify for dental implants if you have missing, broken or severely decayed teeth, that are unrestorable with a normal crown or bridge, and are in relatively good overall health. The only way of determining your eligibility for implants is to consult with an oral care provider to identify whether you have adequate bone support and healthy gums that will support the placement of one or more implants.

What should I expect if my dentist and I decide dental implants are right for me?

The placement of dental implants is a multi-step process that typically takes between 3 and 6 months to complete. It begins with a surgical procedure during which a titanium implant is placed where a previous natural tooth root once existed. The gums are sutured over the implant, where it will stay for several months while osseointegration begins fusing the implant with the surrounding bone. Due to the nature of implant placement, the average procedure time is between 1 and 2 hours, during which you will be comfortably sedated and/or anesthetized for the duration of the treatment. At the conclusion of the healing period, you will return to be fitted for permanent crowns and/or other dental prosthetics.

What type of post-treatment care will I require?

It is normal to experience some discomfort, which may include slight bruising and/or swelling following a dental implant procedure. However, inflammation and pain may be managed with over-the-counter medications, hydrocodone, or codeine. You may be asked to eat only soft foods for approximately 1-2 weeks until the surgical site heals.

Newport-Irvine Dentures

Dentures are removable tooth prosthetics designed to look and function like natural teeth. For thousands of years, some form of denture has been used to fill in the gaps left by missing teeth, although today’s dentures are much more advanced and easier to care for. Most dentures are composed of replacement teeth attached to plastic bases that take on the appearance of the gums. They are used to compensate for one or more missing teeth, referred to as partial dentures, or are available as complete sets of teeth, referred to as complete dentures. Many dental patients elect dentures for tooth replacement if they are not candidates for dental implants or are otherwise looking for a tooth replacement option that is more affordable and budget-friendly.

Removable Dentures

Caring for Your Dentures

Your dentures are custom designed to fit your smile, but did you know that improperly caring for them can cause them to become distorted? Most removable dentures must maintain moisture to retain their shape. Be sure to wash them after eating, gently clean them once daily, and allow them to soak overnight in a denture soaking solution. This will keep your dentures clean and free of stains, which ultimately helps your smile look its best.

Frequently Asked Questions

How do I know if I am a candidate for removable dentures?

If you are missing one or more teeth and thinking of getting dentures at Newport-Irvine Dental, you will first need a professional consultation with Dr. Grupe. During this time, you can explore your tooth prosthetic options, ask questions, and make a decision as to whether dentures are right for you.

What should I expect when being fitted for dentures?

Many factors can be involved in the stages of preparation of your mouth for either partial or full dentures. These will be individually discussed with you by Dr. Grupe during your consultation appointment.

Will I need to follow any special after-care instructions?

Once your dentures are ready, you can begin wearing them on a daily basis. Expect the first few weeks to be an adjustment period, during which time you will adapt to the feel of your new dentures. You may also experience slight irritation or soreness from initial denture wear, and a follow-up appointment with Dr. Grupe may be required to further refine the fit of your denture.
