What makes a beautiful smile? Beautiful teeth, for sure. But there's also another component that can make or break your smile, regardless of your teeth's condition: your gums. Although their primary function is to protect and stabilize the teeth, your gums also enhance them aesthetically by providing an attractive frame.
But just as a painting displayed in an oversized frame can lose some of its appeal, so can your smile if the size of your gums appears out of proportion with your teeth. Normally, a smile that displays more than four millimeters of gum tissue is considered “gummy.”
There are some things we can do to improve your gum to teeth ratios. What we do will depend on which of the following is the actual cause for your gummy smile.
Excess gum tissue. We'll start with the obvious: you have excess gum tissue that obscures some of the visible tooth crown. We can often correct this with a surgical procedure called “crown lengthening,” which removes some of the excess tissue and then reshapes the gums and bone to expose more teeth length.
Teeth that appear too short. The problem may not be your gums — it could be your teeth appear too short. This can happen if the teeth didn't erupt fully, or if they've worn down due to aging or a grinding habit. One option here is to “lengthen” the tooth cosmetically with veneers, crowns or other bonding techniques.
Higher lip movement. Rather than your teeth and gums being out of size proportion, your upper lip may be rising too high when you smile, a condition known as hypermobility. One temporary fix is through Botox injections that paralyze the lip muscles and prevent their movement from overextending. We could also use periodontal surgery to perform a lip stabilization procedure that permanently corrects the upper lip movement.
Overextended jaw. Your gums may seem more prominent if your upper jaw extends too far down and forward. In this case, orthognathic (jaw straightening) surgery might be used to reposition the jaw relative to its connection with the skull. Setting the jaw up and back in this way would reduce the prominence of the gums when you smile.
As you can see, treatments range from cosmetic techniques to moderate surgical procedures. A full dental exam will help determine which if any of these measures could reduce gumminess and improve 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.
