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.

You've just finished your daily brushing and flossing. How did you do? Swiping your tongue across your teeth can generally tell you: It's a good sign if it glides smoothly; but if it feels rough and gritty, you better take another run at it.
This "tongue test," however, only gives you a rough idea of how well you're removing plaque, that thin bacterial film on teeth most responsible for dental disease. Plaque, though, can be sneaky, "hiding" in the nooks and crannies on the biting surfaces of teeth, around the gum line and in between teeth.
So, how do you know if you're clearing out any plaque holdouts? An effective way is to use a plaque disclosing agent. This over-the-counter dental product consists of a swab, tablet or solution, which contains a dye that's reactive to plaque.
After brushing and flossing as usual, you apply the solution to your teeth for about 30 seconds. You then take a look in the mirror: Any remaining plaque will be stained a bright color that makes it stand out. There are also agents with two colors of dye, one that stains older plaque and one for newer plaque.
The plaque staining not only helps you see how well you've been brushing and flossing, it can also show you areas in need of improved hygiene. For example, if you notice a scalloped pattern around the gum line, that may mean your brush isn't getting into that area effectively. In this way, you can use a disclosing agent to fine-tune your hygiene.
Repeated use of a disclosing agent is safe, but just remember the dye color can be vivid. It does wear off in a few hours, though, so perhaps schedule it for a day off around the house. You should also avoid swallowing any solution or getting any of it on clothing.
The ultimate test, though, is a thorough dental cleaning with your dentist at least every six months. They can verify whether you've been fairly successful with your brushing and flossing, or if you have room for improvement. If you do use a disclosing agent, you can also discuss that with them in working out better strategies to protect your teeth from tooth decay and gum disease.
