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.

A beautiful smile is a balanced smile, especially in regard to your gums. A normal smile usually shows 4 mm or less of gum tissue along with about 10 mm of tooth length. But if your gums show more than that, your smile may seem too gummy. In terms of perceived balance, this could detract from your smile's attractiveness.
Fortunately, you don't have to live with a gummy smile—there are various ways to correct or minimize its effect. First, though, we'll need to determine the underlying cause before deciding on the best treatment. And, there are several possible causes, the obvious being too much gum tissue present. Teeth that appear shorter due to wear or incomplete eruption could also make the gums appear larger.
We may be able to correct these size problems by surgically removing and reshaping excess gum tissues and possibly the underlying bone to reveal more of the teeth. We can also bond composite resins or porcelain veneers to shorter teeth to make them appear larger.
But not all gummy smile problems pertain directly to the teeth and gums; instead, it could be your upper lip moves too far up as you smile (hypermobility). Or, your upper jaw may be too long for your face, which can also cause too much of the gums to show during smiling.
With upper lip hypermobility, we may be able to inhibit the lip muscles' movement temporarily with Botox injections that partially paralyze the muscles (the effect eventually wears off, so this treatment will need to be repeated). A periodontist, an oral surgeon, or a plastic surgeon could also permanently alter the upper lip movement through a surgical procedure. Surgery may also be necessary for an abnormally long upper jaw: orthognathic surgery re-positions the jaw to the skull, which can lessen the amount of gums showing.
If your smile is too gummy, we can transform it. But first, let's find out what the real cause is with a comprehensive dental examination. Once we know, we can better advise you on the best way to bring beautiful balance to your smile.

Your gums not only support and protect your teeth they also help present them in a visually attractive way. But some people’s gums seem to stand out too much — what’s commonly called a gummy smile — which diminishes their smile appeal. There’s no precise definition, but as a rule of thumb we consider a smile too gummy if four or more millimeters (about an eighth of an inch) of the gums show.
Fortunately, there are some techniques to improve a gummy smile. Which technique is best for you, though, will depend on why the gums are prominent — and causes vary. For example, you could have a gummy smile because your teeth appear too short compared to your gums.
Permanent teeth normally erupt to about 10 mm of visible length. But less than that, say 8 mm, could skew the visible proportion of gums to teeth too much toward the gums. Teeth can also appear shorter due to accelerated wear caused by grinding habits. Another cause could be the amount of upper lip rise when you smile. The lip may rise too high in a condition called hypermobility. This could reveal too much of the gums when you smile.
It’s important then to match the treatment to the cause. For example, we can enhance the appearance of shorter teeth through a surgical procedure known as crown lengthening.Â During this procedure a surgeon reshapes the gum tissues and underlying bone to expose more of the tooth’s length.
For upper lip hypermobility, we can restrict movement with Botox, a drug that paralyzes tiny parts of the involved muscles. This approach, though, will wear off in a few months — a more permanent solution is surgery to reposition the muscle attachments so as to prevent excessive movement.
If you’re concerned about a gummy smile, see us for a full examination and consultation. Once we know the reason why, we can offer a solution that will make your smile more attractive.
