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.

In one respect, celebrities are no different from the rest of us—quite a few famous people love to collect things. Marie Osmond collects dolls (as well as Johnny Depp, reportedly); Leonardo DiCaprio, vintage toys. And, of course, Jay Leno has his famous fleet of cars. But Victoria Beckham's collection is unusually "familial"—she's kept all of her four children's "baby" teeth after they've fallen out.
Best known as Posh Spice of the 1990s group Spice Girls and now a fashion designer and TV personality, Beckham told People Magazine that she has an "entire bucket" of her kids' primary teeth. And, she recently added to it when her nine-year old daughter lost another tooth earlier this year.
You may or may not want to keep your child's baby teeth, but you'll certainly have the opportunity. Children start losing their first set of teeth around age 6 or 7 through early puberty. During the process, each tooth's roots and gum attachment weakens to the point that the tooth becomes noticeably loose. Not long after, it gives way and falls out.
Although a baby tooth doesn't normally need any help with this, children (and sometimes parents) are often eager to accelerate the process. A loose tooth can be annoying—plus there's often a financial incentive via the "Tooth Fairy!"
First off, there's not much harm in a child wiggling a loose tooth—it may even help it come out. It's also possible to help the tooth safely detach sooner by taking a small piece of tissue, folding it over the tooth and giving it a gentle downward squeeze. If it's loose enough, it should pop out.
If it doesn't, don't resort to more forcible measures like the proverbial string and a door—just wait a day or two before trying the gentle squeeze method again. Once the tooth comes out, the empty socket may bleed a bit or not at all. If heavy bleeding does occur, have the child bite down on a piece of clean gauze or a wet tea bag until it stops. You may also have them eat softer foods for a few days to avoid a resumption of bleeding.
Beyond that, there's little else to do but place it under your child's pillow for the Tooth Fairy. And if after their "exchange" with that famous member of the Fae Folk you find yourself in possession of the erstwhile tooth, consider taking a cue from Victoria Beckham and add it to your own collection of family memories.
Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.
Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).
A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.
In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.
But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.
Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.
If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.
Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.
