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 lot of people don’t like dental work because they believe it will be painful or uncomfortable. There’s an anatomical reason to back up that concern — the mouth with its dense network of nerves in the teeth and gums is one of the most sensitive parts of the human body.
But modern dentistry has helped solve much of the problem of pain with advances in local anesthesia. Using substances that temporarily block electrical impulses within the nerves of a selected area of oral tissues, there’s a good chance you’ll feel little to no discomfort even during moderately invasive procedures.
Unfortunately, you might have heard some complaints from others about local anesthesia that might make you wary of it. Many of these complaints, however, aren’t fully based on all the facts. So, let’s set the record straight about local anesthesia and what you can expect.
No need to be afraid of needles. Nobody enjoys the painful prick from an injection needle, and some people are highly fearful of them. But although it’s necessary to use a needle to deliver anesthesia to deeper levels of tissue, it’s possible you won’t feel it. That’s because we’ll typically apply a topical numbing agent to the skin surface that deadens the top layers where we insert the needle.
That numb feeling afterward won’t last long. One of the chief complaints in the past about local anesthesia was the irritating numbness that could long linger after a procedure. Today, however, with more advanced anesthetics and formulae, we’re better able to gauge the duration of the medication’s effect. This has greatly reduced the length of time afterward your mouth might have that awkward numbing sensation.
Anesthesia isn’t necessary for every procedure. Unless you have hypersensitive teeth, a lot of dental procedures don’t require anesthesia. Your enamel, for example, has no nerves and actually serves as a kind of “muffler” for sensations to lessen their effect. Cleaning your teeth or removing portions of the enamel can normally be performed without the need for numbing medication.
For procedures, though, where pain could be a factor, local anesthesia can make all the difference in the world. In these cases, anesthesia is your friend — it can help you receive the dental care you need without the discomfort.
