You may be among the one in three Americans who suffer from the pain of tooth sensitivity. Before attempting treatment, though, we must first identify the cause.
Your teeth are made of layers of different organic tissue. The pulp at the center of the tooth contains nerves that transmit pain or pressure sensation to the brain. The pulp is encased by dentin, a layer of tissue composed of tiny tubules that conduct temperature and pressure changes from outside the tooth to the pulp nerves. The hard outer enamel shell shields the dentin from over-stimulation from these sensations.
There are, however, some instances where the dentin may become exposed and cause sensitivity in the tooth. This can occur when the gum tissue recedes and the root of the tooth is exposed to the oral environment. If the root loses its surface coating (referred to as cementum, a cement-like outer layer around the root surfaces) because of over-aggressive brushing (too hard for too long) or advanced periodontal (gum) disease, sensitivity is often the result.
Another instance is enamel erosion. Although made of the hardest substance in the human body, enamel has one major enemy — acid. A high oral acid level brought on by over-consuming acidic foods and beverages or as a symptom of gastric reflux disease dissolves (de-mineralizes) the enamel’s mineral content. Brushing just after eating actually contributes to de-mineralization because the enamel is in a softer state. It requires forty-five minutes to an hour for your saliva to neutralize acid and restore minerals to the enamel — you may actually be brushing away enamel with this practice.
Once we know the underlying cause, we can use an appropriate method to reduce sensitivity. One way is to reduce nerve sensitivity in the dentin’s tubules or block them altogether. There are several chemical products for both home and dental office application that can reduce sensitivity and encourage enamel re-mineralization (as can the fluoride added to toothpaste). We can also strengthen enamel and provide a mechanical barrier to acid through concentrated fluoride in a varnish applied to tooth and root surfaces. And, life-like restorations like crowns or veneers not only improve the appearance of your teeth, they can also provide coverage for exposed dentin.
If you are experiencing painful sensitivity, make an appointment to visit us. Once we know the source, we can treat the problem and reduce your discomfort.

Boston Bruins defenseman Zdeno Chara had a rough Stanley Cup final against the St. Louis Blues this past June. Not only did the Bruins ultimately lose the championship, but Chara took a deflected puck shot to the face in Game Four that broke his jaw.
With the NHL season now over, the 42-year-old Bruins captain continues to mend from his injury that required extensive treatment. His experience highlights how jaw fractures and related dental damage are an unfortunate hazard in hockey—not only for pros like Chara, but also for an estimated half million U.S. amateurs, many in youth leagues.
Ice hockey isn't the only sport with this injury potential: Basketball, football (now gearing up with summer training) and even baseball players are also at risk. That's why appropriate protective gear like helmets and face shields are key to preventing injury.
For any contact sport, that protection should also include a mouthguard to absorb hard contact forces that could damage the mouth, teeth and gums. The best guards (and the most comfortable fit) are custom-made by a dentist based on impressions made of the individual's mouth.
But even with adequate protection, an injury can still happen. Here's what you should do if your child has an injury to their jaw, mouth or teeth.
Recognize signs of a broken jaw. A broken jaw can result in severe pain, swelling, difficulty speaking, numbness in the chin or lower lip or the teeth not seeming to fit together properly. You may also notice bleeding in the mouth, as well as bruising under the tongue or a cut in the ear canal resulting from jawbone movement during the fracture. Get immediate medical attention if you notice any of these signs.
Take quick action for a knocked-out tooth. A tooth knocked completely out of its socket is a severe dental injury. But you may be able to ultimately save the tooth by promptly taking the following steps: (1) find the tooth and pick it up without touching the root end, (2) rinse it off, (3) place it back in its socket with firm pressure, and (4) see a dentist as soon as possible.
Seek dental care. Besides the injuries already mentioned, you should also see a dentist for any moderate to severe trauma to the mouth, teeth and gums. Leading the list: any injury that results in tooth chipping, looseness or movement out of alignment.
Even a top athlete like Zdeno Chara isn't immune to injury. Take steps then to protect your amateur athlete from a dental or facial injury.

Dental veneers—thin, life-like layers of porcelain bonded to teeth—can turn a so-so smile into a beautiful one. But most veneers have a distinct drawback: To make them look as natural as possible, the teeth they're bonded with must have some of their surface enamel removed.
Even though they're 1 millimeter or less in thickness, veneers on an unprepared tooth can look bulky. Removing some of the surface enamel remedies this, but doing so permanently alters the tooth. The tooth will need a veneer or some other protective restoration from then on.
Now, though, there's an alternative veneer available for many dental patients. Known as No-Prep or Minimal-Prep, these new veneers are often as thin as a contact lens.
These new types of veneers can often be placed directly on the teeth just above the gum line without any enamel removal and look natural. At the most, the enamel beneath them may need reshaping with an abrasive tool. And, unlike traditional veneers with tooth alteration, these low-prep veneers can often be applied without anesthesia, and in as few as two appointments.
No- or Minimal-Preps are better suited for certain kinds of patients: those with small teeth or teeth that appear small due to larger mouth features; worn teeth from aging or teeth grinding or with small gaps; narrow smiles where the side teeth aren't as visible; and teeth that are slightly misshapen or with minor staining.
On the other hand, patients with oversized teeth or front teeth that jut forward may still encounter problems with an unnatural, bulky appearance even with ultra-thin veneers. The latter situation can often be corrected with orthodontic treatment first to realign the teeth to their proper positions. Once the bite is corrected, no-prep veneers may then become a viable option.
If you'd like to consider these minimal preparation veneers, see your dentist for an examination. The exam results will help determine what type of veneer solution is right for you. And whether you go with traditional or No-Prep veneers, the change in your smile can be amazing.

Congratulations—you’re engaged! It’s a stupendous (and hectic) time in your life as you plan your upcoming wedding.
You want to look your best for the big day—which means you may be dieting, exercising or making changes to your hairstyle and makeup. Be sure, though, to consider another important part of your appearance—your teeth and gums. Here are a few options that could help your wedding day smile shine even more.
Cleanings and whitening. While dental cleanings are primarily about removing disease-causing plaque and tartar they can also give your teeth that clean and polished look. And if you want an extra boost in brightness, consider whitening—we may be able to lighten up your teeth’s stain-induced dullness.
Bonding. If your teeth have slight imperfections—chipping, slight gaps or staining that doesn’t respond well to whitening, consider bonding techniques to repair or cover these defects. Composite resin is a dental material that can be shaped and bonded to teeth to reform a deformed tooth—and with color matching as well. For more extensive defects you can cover the front of imperfect teeth with bonded porcelain veneers or completely cap a tooth with a custom crown.
Tooth restorations. If you have missing teeth marring your smile, you have several options. The top choice: dental implants, which replaces the root of the tooth and will be able to have a crown attached to it. An implant can thus restore both better function and appearance. For more affordable options, you can also turn to fixed bridges or removable dentures. The latter can be custom designed to replace all the teeth on a jaw arch or just a few in different locations.
Gum enhancements. Teeth aren’t the only part of your smile that might need a helpful touch—your gums’ appearance might also be a problem. There are cosmetic procedures including plastic surgery and tissue grafting that can help correct overly prominent “gummy” smiles or, at the other end of the spectrum, longer appearing teeth because of gum recession.
Orthodontics. If you have extended time before the wedding date, we may be able to correct crooked teeth or a poor bite (malocclusion) that’s adversely impacting your smile. In some cases, you may be able to choose clear aligners, removable plastic trays that are hardly noticeable to others, over more visible braces to correct your bite.
Your gums’ primary role is to protect your teeth and keep them firmly in place. But periodontal (gum) disease can damage your gums to such an extent you could ultimately lose your teeth.
Gum disease is a progressive infection caused by bacterial plaque built up on tooth surfaces from poor oral hygiene. The initial infection triggers inflammation, a defensive response of the body characterized by swelling, redness and bleeding of the gums. An initial form of the disease known as gingivitis occurs in most people after just a few days without brushing or flossing.
Resuming hygienic activities to remove daily plaque, along with regular dental cleanings, may be enough to stop gingivitis and restore healthy gums. If the disease is allowed to advance, however, the infected gum tissues will begin to detach from the teeth, turning the slight normal gaps between teeth and gums into wider voids known as periodontal pockets that fill with bacteria leading to infection. Your hygiene efforts will not be enough to cope with this advanced form of periodontal disease.
At this point professional techniques are required to adequately remove plaque and calculus (hardened plaque deposits), depending on the depth and location of the periodontal pockets. The most basic of these is scaling using specialized hand instruments or ultrasonic equipment to remove plaque and calculus in pockets at or just below the gum line. If plaque and calculus have extended to the roots we may then need to employ root planing, in which we “shave” offending material from root surfaces. In some cases this may require accessing the area surgically beneath the gum tissue.
As plaque removal progresses, inflammation will begin to subside and the gum tissues heal. If, however, swelling, bleeding or pus formation persists, this may indicate bacterial levels remain too high. To decrease these levels we may need to administer antibiotics, or through mouthrinses containing chlorhexidine.
Once under control, it’s crucial from then on for you to maintain a strict daily regimen of brushing and flossing to keep plaque from building up on tooth surfaces. You'll also need to visit us regularly (two or more times a year) for professional cleaning and checkups. Keeping a close eye will help prevent a reoccurrence of this serious disease and prolong the life of your teeth.
