Besides straight and translucent teeth, an attractive smile has another important component: balance. In a great smile, the visible areas of the teeth and gums are in balanced proportion to one another.
But what is the ideal proportion between teeth and gums? Although aesthetic appeal is largely “in the eye of the beholder,” dental professionals typically consider a properly sized tooth to be around 10 mm in visible length. As for the upper gums, no more than 4 mm of tissue should show when smiling. Teeth appearing shorter than 10 mm or the gums displaying more than 4 mm can create an effect called a “gummy smile.”
Fortunately, there are different approaches for correcting a gummy smile, depending on what's causing the appearance of gumminess. Not only are there different causes, but they can be diverse in nature.
Obviously, an actual excess of gum tissue can cause a smile to look gummy—but so can shortened teeth. One possible solution called crown lengthening could help correct either possibility. During the procedure, we remove any excess gum tissue or reposition the gums after reshaping the underlying bone to reveal more of the tooth crown. Worn or shortened teeth can also be made to look longer with porcelain veneers.
A gummy smile could also be caused by a hypermobile lip, in which the lip rises higher than normal while smiling. We may be able to prevent this temporarily by injecting Botox into the lip muscles, which paralyzes them and inhibits their ability to move upward. A more permanent approach is to surgically restrict the upward movement of the lip muscles.
The gums may also seem too prominent if the upper jaw is longer in proportion to the face. One way to correct this is orthognathic surgery, a procedure that moves the upper jaw to a higher position on the skull. This can reduce the jaw profile with the face and subsequently affect how much of the gums show while smiling.
These solutions range from relatively minor to significantly invasive. The first step, though, is to find out what's really behind your gummy smile before taking the next step to make it more attractive.

What makes a beautiful smile? The teeth, of course: bright, evenly shaped and precisely aligned with each other. But your teeth can be as perfect as can be and your smile will still appear unattractive.
The reason? Your gums show more than they should when you smile.
What's considered a gummy smile is largely a matter of perception that can vary from person to person. As a rule of thumb, though, we consider a smile “gummy” if four millimeters (mm) or more of the gums show.
Fortunately, we can minimize the gums' prominence and make your smile more attractive. But what methods we use will depend on why your gums stand out. And it's not always because of the gums themselves.
It could be your teeth didn't erupt normally during dental development. Mature crown (the visible part of the tooth) length is normally about 10 mm with a width about 75-85% of that. But an abnormal eruption could result in teeth that appear too short, which can make the gums stand out more. We can correct this with a surgical procedure called crown lengthening in which we remove excess gum tissue and, if necessary, reshape the underlying bone to expose more of the tooth crown.
Another potential cause is how far your upper lip rises when you smile. Normally the lip rises only enough to reveal about 4 mm of teeth. In some cases, though, it may rise too high and show more of the gums. We can modify lip movement in a number of ways, including Botox injections to temporarily paralyze the lip. A more permanent solution is a lip stabilization procedure. It sounds bad, but it's a fairly simple procedure to surgically reposition the muscle attachments to restrict movement.
Your gummy smile may also result from an upper jaw too long for your facial structure. We can correct this with orthognathic (“ortho” – straighten, “gnathos” – jaw) surgery. During the procedure the surgeon permanently positions the jaw further up in the skull; this will reduce the amount of teeth and gums displayed when you smile.
Discovering the true cause of your gummy smile will determine how we treat it. After a complete oral examination, we can then discuss your options to transform your smile into a more attractive one.
