A “gummy” smile, in which the upper gums are too prominent, is a common condition. There are several causes for gummy smiles — determining which one is the first step to having your appearance changed.
Although perceptions vary from person to person, most dentists agree a gummy smile shows 4 mm or more of gum tissue, and the amount is out of proportion with the length of the crown (the visible tooth). Teeth normally erupt through the gums during childhood and continue development until early adulthood, shrinking back from the tooth until stabilizing in place.
This typically produces a crown length of about 10 mm, with a “width to length” ratio of about 75-85%. But variations can produce differences in the relationship between teeth and gums and the width to length ratio of the teeth. The teeth may appear shorter and the gums more prominent. Worn teeth, caused by aging or grinding habits, may also appear shorter.
If tooth to gum proportionality is normal, then the cause may be upper lip movement. When we smile, muscles cause our lips to retract 6-8 mm from the lip’s resting position. If the amount of movement is greater (meaning the lip is hypermobile), it may show too much of the gums. The upper jaw can also extend too far forward and cause the gums to appear too prominent.
There are a number of ways to improve gummy smiles, depending on the cause. Periodontal plastic surgery known as crown lengthening removes and reshapes excess gum tissue to reveal more of the tooth. Lip hypermobility can be reduced with Botox injections (to paralyze the muscles) or in some cases with surgery to reposition the muscle attachments. Orthognathic surgery can be used to surgically reposition an overextended upper jaw. Other cosmetic enhancements such as orthodontics, bonding or porcelain restorations can also prove effective.
The first step is to obtain an accurate diagnosis for your gummy smile. From there, we can devise the best treatment approach to bring your smile back into a more attractive proportion.

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.

There's a lot of emphasis — well-placed, of course — on preventing and treating tooth decay. But there's another dental disease just as dangerous to your oral health and nearly half of U.S. adults have it. It's actually a group of diseases known collectively as periodontal (gum) disease.
Gum disease is similar to tooth decay in one respect: they're both triggered by bacteria. These microorganisms thrive in a thin film of food particles called plaque that collects on tooth surfaces.
Certain bacteria can infect gum tissues and trigger inflammation, a response from the body's immune system to fight it. As the battle rages, bone loss can occur and the gums weaken and begin to detach from the teeth. Without treatment, you could eventually lose affected teeth.
Like tooth decay, the best approach with gum disease is to prevent it, and by using the same techniques of daily brushing and flossing. These actions loosen and remove plaque built up since your last brushing. It's also important you visit us at least twice a year for cleanings that remove hard to reach plaque and calculus (hardened plaque deposits).
If despite your best efforts you do contract gum disease, the sooner you see us for treatment the lower the long-term impact on your health. The treatment aim is the same as your daily hygiene: to remove plaque and calculus. We use specialized hand instruments or ultrasound equipment to mechanically remove plaque; more advanced cases may require the skills of a periodontist who specializes in caring for structures like the gums that support teeth.
So, defend yourself against gum disease by brushing and flossing daily, and visiting us regularly for dental cleanings and checkups. If you notice bleeding, swollen or painful gums, see us as soon as possible for diagnosis and treatment. Don't let tooth decay's evil twin ruin your oral health or your smile.

Tooth decay doesn't occur out of thin air, but is the end result of bacteria feeding on sugar, multiplying and producing acid. High acidity erodes tooth enamel and creates an environment for cavity development.
Modern dentistry can effectively treat cavities and often save the tooth from further damage. But you don't have to wait: You can reduce your chances of cavities by managing risk factors that contribute to decay.
Here are 4 top risk factors for tooth decay and what you can do about them.
Poor saliva flow. Saliva neutralizes acid and helps restore minerals to enamel after acid contact. But your enamel may not have full protection against acid if you have diminished saliva flow, often due to certain medications. You can help increase your saliva by consulting with your doctor about drug alternatives, drinking more water or using a saliva boosting product. Smoking can also inhibit saliva, so consider quitting if you smoke.
Eating habits. High sugar content in your diet can increase bacterial growth and acid production. Reducing your overall sugar consumption, therefore, can reduce your risk of decay. Continuous snacking can also increase your decay risk, preventing saliva from bringing your mouth back to its normal neutral pH. Instead, limit your snack periods to just a few times a day, or reserve all your eating for mealtimes.
Dental plaque. Daily eating creates a filmy buildup on the teeth called dental plaque. If not removed, plaque can then harden into a calcified form called calculus, an ideal haven for bacteria. You can help curtail this accumulation by thoroughly brushing and flossing daily, followed by dental cleanings at least every six months. These combined hygiene practices can drastically reduce your cavity risk.
Your genetics. Researchers have identified up to 50 specific genes that can influence the risk for cavities. As a result, individuals with similar dietary and hygiene practices can have vastly different experiences with tooth decay. Besides continuing good lifestyle habits, the best way to manage a genetic disposition for dental disease is not to neglect ongoing professional dental care.

In the world of movies and television, the lead actors get the lion’s share of the credit. In reality, though, there wouldn’t be much of a show without the supporting cast. You’ll find a similar situation in your mouth: While your teeth get most of the attention, another dental structure plays a critical supporting role—your gums.
It’s only fitting, then, that we put the spotlight on your gums, especially in February. The second month of the year is Gum Disease Awareness Month, when we highlight the importance of our gums and the dangers they face.
While the gums are an important part of your smile, they’re not just for show. Your gums play a critical role in helping to keep your teeth securely attached within the jaw. Their network of blood vessels also supplies nutrients and disease-fighting agents to your teeth. We’re not exaggerating, then, when we say your teeth can’t survive without them.
But although they’re resilient, they do have one major vulnerability: a bacterial infection known as periodontal (gum) disease. Gum disease arises from bacteria that thrive within a thin, built-up film of bacteria and food particles called dental plaque. Untreated, an infection can advance deep into the gums, down to the tooth roots and jawbone.
Gum disease is as much a problem for your teeth as it is for your gums: Weakened gum attachment and loss of bone can put your teeth in danger of being lost. Fortunately, though, there are things you can do to keep gum disease from ruining your dental health.
Brush and floss. To prevent a gum infection, you must keep plaque from building up on your teeth. The best way is a combination of thorough brushing and flossing. Don’t neglect the latter, which is necessary to remove hard-to-reach plaque between teeth. And do it every day—it doesn’t take long for a gum infection to occur.
Get your teeth cleaned. Even the most diligent hygiene practice may still miss some plaque and its hardened form calculus (tartar). These stubborn deposits, though, are no match for our dental cleaning equipment and techniques. Semi-annual visits are also a good time to evaluate your overall dental health, including your gums.
See us at the first sign of infection. Gum disease is often symptomless, especially in the beginning. But there are signs to look for like gum swelling, redness or bleeding. If you notice any of these, see us as soon as possible. The sooner you begin treatment, the less harm the disease will cause.
Taking care of your gums isn’t just good for your dental health—it’s good for your overall health and well-being. It also doesn’t hurt that your gums are good for your appearance as an important part of a beautiful smile.
