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.

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.

Q: What is a gummy smile? I’ve never heard that term before.
A: You may not have heard the phrase, but you’ve probably noticed the condition. A “gummy smile” occurs when too much gum tissue (in technical terms, over 4 millimeters, or about one-eighth of an inch) is visible in the smile. Different people have different ideas about when this issue becomes a problem… but if you feel it detracts from your appearance, there are several ways dentists can treat a gummy smile.
Q: What can cause a smile to appear “gummy”?
A: A number of factors can contribute to this perception. One is simply that an excess of gum tissue is covering up the teeth. Another is that the teeth themselves are relatively short; this can be a natural anatomical feature, or it can result from the teeth being worn down by a grinding habit or another cause. In some cases, the problem is that the upper lip is hypermobile, meaning it rises too high when you smile. And in rare instances, the upper jaw is proportionately too long for the face, making the gums and teeth extend down too far.
Q: What’s the best way to fix this condition?
A: It all depends on what is causing the smile to appear gummy. If it’s too much gum tissue, a periodontal procedure called “crown lengthening” can be used to remove the excess tissue and reveal more of the teeth. If the teeth themselves are responsible, they can be crowned (capped), or covered by porcelain veneers. A hypermobile lip can be controlled temporarily with Botox injections, or permanently with a minor surgical procedure. Jaw problems present the most complex condition, but can be successfully treated with orthognathic (jaw-straightening) surgery. Orthodontic treatment may also be recommended in conjunction with these therapies.
Q: I’m unhappy with the way my smile looks, but I’m not sure exactly what’s wrong. What should I do?
A: A great-looking smile comes from the harmonious dynamic between teeth, lips and gums. If you feel your smile could use a little improvement, we can help you identify the things you like about it, and point out the things that need improvement. Working with an experienced cosmetic dentist is the best way for you to get the smile you’ve always dreamed about.
