CrazyLittleThingCalledHyperdontia

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.

The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.

Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces). Some people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.

Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.

After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.

Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

If you have questions about tooth extraction or orthodontics, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Simple Tooth Extraction” and “The Magic of Orthodontics.”

HowDentistsProvideYourChildtheBenefitofX-RaysasSafelyasPossible

X-ray imaging is such an intricate part of dentistry, we usually don't think twice about it. Without it, though, the fight against dental disease would be much harder.

At the same time, we can't forget that x-rays are a form of electromagnetic radiation that can penetrate human tissue. It's that very quality and the difference in the absorption rate between denser bone and teeth and softer diseased tissue that makes disease diagnosis possible.

But this same penetrative power can potentially harm the tissues it passes through. For that reason when practicing any form of x-ray diagnostics, dentists follow a principle known as ALARA, an acronym for "As Low As Reasonably Achievable." In lay terms ALARA means getting the most benefit from x-rays that we can with the lowest dose and exposure time possible.

While practicing ALARA with x-rays is important for patients of any age, it's especially so for children who are more sensitive to radiological energy given their smaller size and anatomy. We can't use the same settings, dosages or exposure times with them as with an adult.

To protect children, dentists have developed techniques and protocols that lessen their exposure time and rate, while still providing usable images for diagnosing disease. The bitewing is a good example of safe and effective pediatric x-ray imaging.

A bitewing is a plastic device holding exposable film that patients bite down on and hold in their mouth while x-raying. The x-rays pass through the teeth and gums and expose the film behind them on the bitewing. Using a bitewing we can capture a set of two to four radiographs to give us a comprehensive view of the back teeth, while exposing the child less radiation than they normally receive daily from background environmental sources.

This and other advances in equipment and digital imaging greatly reduce the amount of radiation patients receive during x-rays. If, though, you're still concerned about your child's x-ray exposure, talk with your dentist who can explain in more detail the x-ray safety protocols they follow. Just like you, they want your child to be as safe as possible while still benefiting from the diagnostic power of x-rays.

If you would like more information on safety precautions using x-rays with children, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “X-Ray Safety for Children.”

CrownLengtheningCouldHelpwithTreatingHardtoReachCavities

There is a primary principle dentists follow regarding tooth decay—treat it as soon as you find it. Something as simple and routine as filling a cavity could prevent future tooth loss.

But treating a cavity at or below the gum line could be anything but simple and routine. Older adults who may also be dealing with gum recession are more likely to have these kinds of cavities where the gums block clear access to it.

But there is a way to access gum-covered cavities with a minor surgical procedure known as crown lengthening. Crown lengthening is commonly used in cosmetic dentistry to expose more of the visible teeth when there's an overabundance of gum tissue or if the teeth are disproportionately small. We can use it in this instance to surgically relocate the blocking gum tissue out of the way of the cavity.

After numbing the area with local anesthesia, tiny incisions will be made in the gums to create a tissue flap. After reshaping the underlying bone to recreate normal anatomy but at a different level, this flap is then moved and sutured to a new position. This exposes enough tooth structure so that the cavity can be repaired after gum healing.

As with any minor surgery, there's a very slight risk of bleeding and/or infection with crown lengthening. If you undergo this procedure, you'll receive post-care instructions for the first few days afterward including avoiding strenuous activities, eating only soft foods and using an ice pack the day of surgery to help control swelling.

This versatile procedure can help save a tooth that might otherwise be lost due to decay. And, it might even improve your appearance.

ConsideranEffectiveandAffordableRPDforTeethReplacement

If you have a few missing teeth but can't afford dental implants or fixed bridgework, consider a removal partial denture (RPD). Although implants may be the superior choice aesthetically and functionally, an RPD can still effectively give you back your teeth.

RPDs are designed to replace one or more missing teeth but not a full arch like a full denture. Considered a permanent restoration, RPDs are also more durable than transitional "flippers," denture appliances that are flexible and light enough to be flipped out of the mouth with a flick of the tongue.

The key to both their affordability and durability is vitallium, a strong but lightweight metal alloy most often used in their frame construction. To it we attach artificial teeth usually made of porcelain or glass-filled resins that occupy the precise location of the missing teeth on the gum ridge. The artificial teeth and frame are surrounded by gum-colored plastic for a more natural look.

Each RPD is custom-made depending on the number and location of the missing teeth. Its construction will focus on minimizing any rocking movement of the RPD during chewing or biting. Too much of this movement could damage the adjacent teeth it's attaching to and cause the appliance to be uncomfortable to wear. We can stabilize the frame by precisely fitting it between teeth to buttress it. We also insert small rests or clasps made of vitallium at strategic points to grip teeth and minimize movement.

RPDs do have some downsides: their unique attachment with teeth encourages the accumulation of dental plaque, the thin bacterial film that's the leading cause of tooth decay and periodontal (gum) disease. These diseases can affect your remaining teeth's health and stability, which could in turn disrupt the fit of the RPD. Also, too much movement of the appliance can make the teeth to which it's attached become more mobile. It's important, then, if you wear a RPD to remove it daily for cleaning (and to thoroughly brush and floss your natural teeth), and to remove it at night to give the attaching teeth a rest.

A RPD can give you back the teeth you've lost for many years to come—if you take care of it. Maintaining both your RPD and the rest of your teeth and gums will help extend the life and use of this effective and affordable replacement restoration.

If you would like more information on teeth replacement options, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Removable Partial Dentures: Still a Viable Tooth-Replacement Alternative.”

Tags: Veneer  

Renew your smile appearance with porcelain veneers from your Ringwood, NJ, dentists, Dr. David Kahn and Dr. John Pergolizzi. Largedental veneers cracks, intractable stains and gaps detract from your smile and harm your self-confidence, too. Perhaps it's time to consults these experts in cosmetic dentistry and see if veneers could achieve the look you desire.

Veneers and you

Porcelain veneers from your Ringwood, NJ, dentist are thin, tooth-shaped shells of premium-grade ceramic. Custom-made to improve the front side of teeth marred by flaws such as big chips, cracks, craze lines and more, veneers remake healthy teeth so they look naturally beautiful. Plus, they strengthen tooth enamel as they are permanently bonded in place.

When you consult with Dr. Kahn or Dr. Pergolizzi, they'll review your oral health. Healthy teeth and gums are essential to veneer placement. That means no active decay or gum disease. Also, you and your dentist will discuss how you wish your smile to appear and consider factors such as tooth length, color and shape. Realistic goals render the best cosmetic dentistry plan and result.

The veneer treatment

As part of the evaluation process, your dentist will take oral impressions. These, along with his specific directions, help the dental technician sculpt and color each veneer.

Also, your dentist will remove a thin slice of enamel from each tooth. This surface reduction allows the veneers to fit properly and makes your treatment permanent. As you wait for your final veneers, you'll wear temporary ones to normalize your smile appearance.

When you return to the office, the doctor will take off the temporary laminates, etch the surface of your teeth and cement the new veneers in place. He can vary the thickness and color of the cement as needed to achieve the strongest bond and the best cosmetic effect.

As you wear your new veneers, your mouth will adjust to how they feel and bite. You may experience a bit of gum or tooth sensitivity. This is normal, and it will diminish quickly.

Your great smile

You'll maintain it with your usual oral hygiene routine:

  • Flossing daily
  • Twice daily brushing
  • Semi-annual cleanings and check-ups with your dentist

Also, stay away from hard foods such as candy apples, and never use your teeth to open packages or to bite on pencils or fingernails. Take it easy on your veneers, and they'll last for a good ten years or more, says the American Academy of Cosmetic Dentistry.
