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.

Today’s healthcare patients are asking questions. They want to know the “why” behind the “what” that their care providers are recommending for their health.
There’s a similar trend in dentistry — and it’s one we dentists encourage. We want you to know the “why” behind your treatment options — because you’re as much a participant in your own dental health as we are. The more informed you are, the better equipped you’ll be to make decisions to maintain or improve your health and the appearance of your smile.
As your dental care partner, it’s also essential we help you develop a long-term care plan based on your needs. There are aspects of dental care that are routine: daily brushing and flossing, an oral-friendly diet, and regular dental cleanings and checkups to assess your oral health. But we also need to think strategically, especially if you have risk factors that could impact your future dental health.
To do this we follow a four-step dental care cycle. In Step 1 we identify all the potential risk factors you personally face. These include your potential for dental disease, which could lead to bone and tooth loss, and the state of your bite and jaw structure that could complicate future health. We’ll also take into account any factors that could now or eventually affect your smile appearance.
Once we’ve identified these various factors, we’ll then assess their possible impact on your health in Step 2, not just what may be happening now but what potentially could happen in the future. From there we move to Step 3: treating any current issues and initiating preventive measures to protect your future health.
In Step 4 we’ll monitor and maintain the level of health we’ve been able to reach with the preceding steps. We’ll continue in this stage until we detect an emerging issue, in which we’ll then repeat our cycle of care.
Maintaining this continuum will help reduce the chances of an unpleasant surprise in your dental health. We’ll be in a better position to see issues coming and help reduce their impact now so you can continue to have a healthy mouth and an attractive smile.

You’ve invested a lot of time and money in orthodontic treatment to improve your smile. If you’re not careful, though, your teeth could actually move back to their old positions. The reason why is related to the same natural tooth-moving mechanism we use to straighten teeth in the first place.
Teeth are held in place by an elastic, fibrous tissue called the periodontal ligament lying between the teeth and the jawbone and attaching to both with tiny collagen fibers. The periodontal ligament allows for incremental tooth movement in response to pressure generated around the teeth, as when we chew (or while wearing braces).
Unfortunately, this process can work in reverse. Out of a kind of “muscle memory,” the teeth can revert to the older positions once there’s no more pressure from the removed braces. You could eventually be right back where you started.
To avoid this, we have to employ measures to hold or “retain” the teeth in their new positions for some time after the braces come off. That’s why we have you wear a dental appliance called a retainer, which maintains tooth position to prevent a relapse. Depending on what’s best for your situation, this could be a removable retainer or one that’s fixed to the teeth.
Patients typically wear a retainer around the clock in the immediate period after braces, and then eventually taper off to just nighttime wear. Younger patients must wear one for several months until the new teeth positions become more secure and the chances of a rebound diminish. For older patients who’ve matured past the jaw development stage, though, wearing a retainer may be a permanent necessity to protect their smile.
Retainer wear can be an annoyance, but it’s an absolute necessity. Think of it as insurance on your investment in a new, more attractive smile.
