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.

Winter is the time for snowy landscapes, hot cocoa and flannel PJs, but for some 'tis the season for tooth trouble. What can you do to keep your teeth from becoming a pain this winter?
Tackle tooth sensitivity. Does crisp winter air on your teeth give you a jolt? A study published in the Journal of the American Dental Association found that 1 in 8 people (over 12%) suffer from tooth sensitivity, particularly to cold. Sensitivity can result from receding gums, erosion of tooth enamel, tooth decay or other dental problems. If you experience tooth sensitivity, use toothpaste that is specially formulated for sensitive teeth and breathe through your nose to protect your teeth from extreme cold. Most importantly, schedule a dental exam to determine why your teeth are sensitive.
Stay hydrated. In winter, we spend more time with the heat on and we tend to drink less water. A dry mouth can result, which can lead to bad breath, tooth decay and gum disease. Staying well hydrated keeps your gums and teeth moist and helps you produce more saliva, which is key to good oral health and fresh breath. Saliva helps wash away food debris and bacteria, neutralize decay-causing acid and repair weakened tooth enamel. For healthy teeth and gums, be sure to drink plenty of water this winter.
Safeguard your teeth on the slopes. Are you planning to hit the slopes this winter? Be sure to wear a mouthguard to help protect against injury. Beginning skiers and snowboarders are more likely to suffer falls that could result in dental injuries, while experts may fly over bumps and jumps, causing the upper and lower teeth to knock together with force. Even backyard sledders are at risk of dental injury. Mouthguards help protect against chipped, broken, or knocked-out teeth as well as soft tissue damage. So before you enjoy wintertime sports, make sure your teeth are protected. For the best fit and comfort, ask us about a custom mouthguard.
If you have questions about these or other dental issues, please contact us or schedule a consultation. You can learn more in the Dear Doctor magazine articles “Treatment of Tooth Sensitivity” and “Dry Mouth.”
You might think David Copperfield leads a charmed life:Â He can escape from ropes, chains, and prison cells, make a Learjet or a railroad car disappear, and even appear to fly above the stage. But the illustrious illusionist will be the first to admit that making all that magic takes a lot of hard work. And he recently told Dear Doctor magazine that his brilliant smile has benefitted from plenty of behind-the-scenes dental work as well.
“When I was a kid, I had every kind of [treatment]. I had braces, I had headgear, I had rubber bands, and a retainer afterward,” Copperfield said. And then, just when his orthodontic treatment was finally complete, disaster struck. “I was at a mall, running down this concrete alleyway, and there was a little ledge… and I went BOOM!”
Copperfield’s two front teeth were badly injured by the impact. “My front teeth became nice little points,” he said. Yet, although they had lost a great deal of their structure, his dentist was able to restore those damaged teeth in a very natural-looking way. What kind of “magic” did the dentist use?
In Copperfield’s case, the teeth were repaired using crown restorations. Crowns (also called caps) are suitable when a tooth has lost part of its visible structure, but still has healthy roots beneath the gum line. To perform a crown restoration, the first step is to make a precise model of your teeth, often called an impression. This allows a replacement for the visible part of the tooth to be fabricated, and ensures it will fit precisely into your smile. In its exact shape and shade, a well-made crown matches your natural teeth so well that it’s virtually impossible to tell them apart. Subsequently, the crown restoration is permanently attached to the damaged tooth.
There’s a blend of technology and art in making high quality crowns — just as there is in some stage-crafted illusions. But the difference is that the replacement tooth is not just an illusion: It looks, functions and “feels” like your natural teeth… and with proper care it can last for many years to come.Â Besides crowns, there are several other types of tooth restorations that are suitable in different situations. We can recommend the right kind of “magic” for you.

While it may not be one of your favorite features in the dental office, the dental drill is nevertheless necessary for treating problem teeth. It’s used primarily for removing decayed or damaged structure and preparing a tooth for fillings or other restorations.
Dental drills have been used for decades and are quite effective — but they have their drawbacks. Their rotating burrs often remove portions of healthy tooth structure along with decayed material. Friction from the drill action can cause discomfort, so local anesthesia is usually needed. Drills can also emit a high-pitched machine noise that’s unsettling to many patients.
There’s a growing alternative to the drill, known as air abrasion. Although the technology has been around since the 1950s, the development of new suction pumps that capture the resulting dust from its use has made it more palatable as an option to the traditional drill.
Also known as particle abrasion, the technique uses a pressurized stream of fine particles (usually aluminum oxide, an abrasive powder) directed at teeth to wear away (abrade) the tooth’s structural surface. We can be quite precise in the amount of surface material removed, so it’s useful for diminishing stains or roughing the surface for bonding materials like composite resin. We’re also able to remove decayed material with very little impact on surrounding healthy structure, and you may not need anesthesia during the procedure.
While this quiet alternative to the noisier drill is quite versatile, it does have its limitations. It’s not that efficient for preparing larger cavities for restoration or for removing older amalgam fillings. The teeth to be treated must be carefully isolated to prevent the fine particle dust produced from being swallowed by the patient or spread into the air. High-volume suction equipment is a must or the procedure will create a “sandstorm” of particles in the room.
Still, for situations suited to it and with proper isolation measures, air abrasion can be effective and comfortable. If the technology continues to improve, the dental drill may soon become a relic of the past.

If you were asked to identify the number one mouth problem affecting dental health, what would you name? Toothaches? Poor hygiene? Jaw joint issues?
Believe it or not, the top issue among 15,000 respondents in a recent American Dental Association (ADA) survey was dry mouth. A full one-third of the respondents had experienced chronic lack of normal saliva flow; difficulty biting and tooth pain, took second and third place, respectively.
We’ve all experienced the discomfort of temporary dry mouth when we first wake up in the morning or after eating certain foods. But chronic dry mouth is much more serious with long-term effects on a person’s teeth and gum health. This is because among its other important properties, saliva helps neutralize enamel-softening mouth acid and restores minerals to enamel after acid contact. Without sufficient saliva flow you’re much more susceptible to dental disease.
While there are several causes for dry mouth, perhaps the most common is as a side effect to at least five hundred known medications. Because older people tend to take more medications than other age groups, dry mouth is an acute problem among people over 60 (a major factor for why dry mouth took the survey’s top health problem spot).
You can help ease dry mouth from medications by first asking your doctor about switching to alternative medications that don’t affect saliva production. If not, be sure to drink more water during the day and especially when you take your oral medication (a few sips before and after).
You can help your dry mouth symptoms from any cause by drinking more water, limiting your consumption of alcohol or caffeine, and avoiding tobacco products. You can also use substances that stimulate saliva flow—a common one is xylitol, an alcohol-based sugar that’s used as a sweetener in certain gums and candies. Not only does xylitol boost saliva flow it also inhibits the growth of bacteria and thus decreases your risk of disease.
And speaking of reducing bacteria and their effects, don’t neglect daily brushing and flossing. These habits, along with regular dental cleanings and checkups, will benefit you just as much as your efforts to reduce dry mouth in avoiding dental disease.
