Your gums not only support and protect your teeth they also help present them in a visually attractive way. But some people’s gums seem to stand out too much — what’s commonly called a gummy smile — which diminishes their smile appeal. There’s no precise definition, but as a rule of thumb we consider a smile too gummy if four or more millimeters (about an eighth of an inch) of the gums show.
Fortunately, there are some techniques to improve a gummy smile. Which technique is best for you, though, will depend on why the gums are prominent — and causes vary. For example, you could have a gummy smile because your teeth appear too short compared to your gums.
Permanent teeth normally erupt to about 10 mm of visible length. But less than that, say 8 mm, could skew the visible proportion of gums to teeth too much toward the gums. Teeth can also appear shorter due to accelerated wear caused by grinding habits. Another cause could be the amount of upper lip rise when you smile. The lip may rise too high in a condition called hypermobility. This could reveal too much of the gums when you smile.
It’s important then to match the treatment to the cause. For example, we can enhance the appearance of shorter teeth through a surgical procedure known as crown lengthening.Â During this procedure a surgeon reshapes the gum tissues and underlying bone to expose more of the tooth’s length.
For upper lip hypermobility, we can restrict movement with Botox, a drug that paralyzes tiny parts of the involved muscles. This approach, though, will wear off in a few months — a more permanent solution is surgery to reposition the muscle attachments so as to prevent excessive movement.
If you’re concerned about a gummy smile, see us for a full examination and consultation. Once we know the reason why, we can offer a solution that will make your smile more attractive.

When you visit us for your regular checkup we're examining more than your teeth and gums. We're also checking to see if you're having problems with soft tissues in and around your mouth.
Besides canker sores, rashes or other types of abnormalities, our exam may uncover strange looking lesions known as lichen planus on the inside of the mouth. These purple-tinted bumps or rash-like discolorations are named for their similarity in appearance to lichen fungi found on trees or rocks. Although these mouth sores may look odd, they're fairly rare and usually do not cause concern.
Most people don't even know they have lichen planus until it's discovered during a dental exam. If there are any symptoms, it's usually a feeling of roughness, tenderness or itching. They may increase your sensitivity to spicy or acidic foods, but rarely cause extreme pain. If they're located around the gums, you may also notice a little soreness after brushing or eating.
To confirm it is lichen planus, we need to perform a biopsy. During this procedure, we remove a tiny amount of the affected tissue and have it examined microscopically. We do this not only to determine the correct diagnosis, but also to rule out more serious problems like pre-cancerous lesions or oral cancer.
Thankfully, though, this worst case scenario is quite rare, and although the condition can't be cured, there are some things you can do to keep any discomfort to a minimum. If the lesions are irritating, we recommend using a soft toothbrush with gentle brushing action. You may also want to limit or avoid spicy or acidic foods like citrus, tomatoes, hot peppers and caffeinated drinks. Managing stress can also help. For some extreme conditions, we can prescribe a topical steroid to help relieve discomfort.
If you notice any of the above symptoms, be sure to contact us or point it out at your next appointment. Once we know what we're dealing with, we can take steps to treat you.

Since their introduction over thirty years ago, dental implants have become the most popular choice for dental restoration. Their large variety of shapes and sizes — a far cry from the limited choices of the 1980s — has only served to increase their popularity.
In recent years there's also been an expansion in their applicability. Most people recognize them as replacements for individual teeth — but they can do much more. They're now playing a pivotal role in other dental restorations or situations.
Here are 3 of those “cutting edge” ways implants could change your dental health and smile for the better.
Fixed bridgework. In a traditional bridge, prosthetic (false) teeth use the natural teeth on either side of the empty space for support. In this updated version, implants become the support base for the bridge. For example, a bridge as small as three crowns can be supported by two implants attached to the outside crowns of the bridge. Four to eight implants can support a bridge as large as an entire arch of teeth.
Over-dentures. In cases of significant bone loss, a full or partial denture may be a better option than a fixed bridge. Traditional dentures, though, can contribute to even more bone loss, which can cause the dentures to eventually lose their fit. Implants not only can help stop further bone loss but can also stimulate increased bone density. Two or more standard or mini-sized-sized implants can support a full or partial denture.
Orthodontics anchorage. People with missing teeth aren't the only ones who can benefit from implants. While most bite repairs only require the back teeth to provide anchorage for braces, certain complex bites may need a different point of anchorage. Orthodontists can create a more feasible anchorage point with an implant or a temporary anchorage device (TAD) imbedded in the jaw. This can help isolate teeth that need to be moved from those on the arch that don't.
