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.
