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.

Surgical treatment for periodontal (gum) disease can go a long way toward restoring your mouth to good health; however, it does not change your susceptibility to the disease. That’s why we recommend that you come in regularly for periodontal cleanings after your treatment. Here are some frequently asked questions about keeping your mouth healthy after gum disease treatment.
How often do I have to come in for periodontal cleanings?
There’s no “one-size-fits-all” answer to that question: It really depends on your individual situation. For example, some individuals may have a more aggressive form of periodontal disease that requires more frequent periodontal maintenance (PM) treatments to maintain control. Others may have greater success controlling the buildup of disease-causing plaque with at-home oral hygiene measures, and therefore need PM less often. However, for people with a history of periodontal disease, getting PM treatments at a three-month interval may be a good starting point.
What happens at a periodontal maintenance appointment?
A thorough cleaning of the crown and root surfaces of the teeth, aimed at removing sticky plaque and hardened dental calculus (tartar), is a big part of PM treatments — but there’s much more. You’ll also receive a thorough clinical examination (including oral cancer screening), a review of your medical history, and x-rays or other diagnostic tests if needed. The status of any ongoing periodontal disease will be carefully monitored, as will your success at maintaining good oral hygiene. Decisions about further treatment will be based on the results of this examination.
What else can I do to keep gum disease at bay?
Keeping your oral hygiene in top-notch condition — which includes effective brushing and flossing every day — can go a long way toward controlling gum disease.Â In addition, you can reduce risk factors by quitting tobacco use and eating a more balanced diet. And since inflammatory conditions like diabetes, arthritis and cardiovascular disease can make periodontal disease worse (and vice versa), keeping these conditions under control will greatly benefit both your oral health and your overall health.
If your tooth sustains damage that compromises its structure — typically through decay or trauma — you have several options depending on the extent of the damage: One of them is a crown. This method saves the tooth and its root and completely conceals the visible portion of the tooth, or crown, under a natural-looking cap made to mimic as closely as possible the size, shape and color of the original tooth.
Crowns also hide imperfections in the original tooth like discoloration, chipping, fractures, excessive wear (from bruxism, or tooth grinding, for example), or abnormalities in the way the tooth formed. And they’re used following root canal treatments, which treat infected pulp at the center (canal) of a tooth root by removing the pulp and replacing it with an inert, rubber-like material.
Saving the natural tooth has long been the goal of dentistry because normal micromovements of the tooth root, which is suspended in its jawbone socket by elastic ligaments, stimulate the surrounding bone to rejuvenate. Without that stimulation, the bone continues to lose old cells, but no longer replaces them. Crowns are also designed to restore tooth function.
The function and location of the damaged tooth can determine what material the crown will be made of. If the damaged tooth is clearly visible when you smile, porcelain, the most realistic-looking material, is almost always used. If the tooth receives significant bite force, a stronger material is considered — either, a gold/porcelain combination, or a high-strength ceramic. If you are restoring a second molar, an all-gold crown may be considered.
With the advent of dental implants, saving a damaged tooth is no longer the only option for preserving the health of the bone surrounding the tooth root. The implant — a tiny biocompatible, titanium screw-like artificial root — is placed in the jawbone and is then capped with a natural-looking crown of course!
