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.

After months or even years of radiation or chemotherapy, the words "cancer-free" is music to your ears. Your joy and relief, though, may be tempered by the toll these treatments can take on the rest of your body—including your mouth.
Both of these treatments can destroy healthy tissue along with targeted cancer cells. If the focus has been on the head and neck regions, they could damage the salivary glands to the point that they won't produce adequate saliva flow.
A lack of saliva can have a detrimental effect on your oral health. Saliva buffers and helps lower oral acid levels that soften and erode enamel and increase the likelihood of tooth decay. Saliva also supplies antibodies that fight disease-causing bacteria. Otherwise, bacteria—and the risk for disease—can rapidly grow.
If these or other scenarios occur, you may experience dental damage, even tooth loss. Fortunately, we can restore an injured smile in various ways, including dentures, bridges or dental implants. But we should also attempt to limit the potential damage by taking steps to prevent dental disease during cancer treatment.
The most important of these is to brush and floss daily. Everyone should practice these hygiene tasks to remove disease-causing dental plaque, regardless of their health status. But because some natural disease-fighting mechanisms in the mouth may be disrupted during either radiation or chemotherapy, it's even more important if you're a cancer patient.
It's equally important to maintain as much as possible regular dental visits during cancer treatment. Dental cleanings provided during these visits remove any residual plaque and tartar (hardened plaque), which further lowers your disease risk.
Your dentist can better monitor your overall dental condition during frequent visits and provide as much treatment as you can tolerate. They can also enhance your protection against disease by prescribing antibacterial mouthrinses, fluoride applications or products to boost saliva production.
Some teeth and gum problems may be unavoidable; in that case, you may need post-treatment dental care to restore your oral health as needed. But caring as much for your dental health as you're able during cancer treatment could help you realize a better outcome.
Dental plaque, that gritty bacterial film coating your teeth, is the top cause for tooth decay and periodontal (gum) disease. You can see and feel a lot of it—but not all of it. Some deposits can lodge snugly between your teeth, and can cause dental disease just as much as what's out in the open.
The problem with between-teeth plaque is that even a solid brushing habit might not effectively remove it. That's why you flossing should also be part of your daily oral hygiene.
If the thought of flossing, however, causes you to let out an audible sigh, we understand. Flossing typically engenders less enthusiasm than brushing, mainly because many find flossing time consuming and difficult to do.
If traditional flossing isn't your bag, we may have a reasonable alternative. Oral irrigation is a hygiene method for removing plaque between teeth using a pressurized water spray. You direct the water spray between your teeth using a handheld wand (which somewhat resembles a power toothbrush) and small hose attached to a countertop pump appliance.
A mainstay in dental offices, oral irrigators (or water flossers) have been available for home use since the 1960s. They're ideal for people who have problems with manual dexterity or who may not want to contend with flossing thread. They also make it easier for patients wearing braces to clean between their teeth, a monumental task using regular floss.
As to effectiveness, oral irrigation appears to match that of regular flossing, especially for orthodontic patients. Clinical studies in the early 2000s compared patients with braces using oral irrigation with those who were brushing only. Those using irrigation were able to remove five times as much plaque as the other group.
There are a number of comparable oral irrigation brands on the market from which to choose, and your dentist can advise you on features to look for when purchasing one. Just be sure you're using some method, oral irrigation or traditional flossing, to remove disease-causing plaque from between your teeth—either will go a long way in keeping your teeth and gums healthy.

During this year's baseball spring training, Minnesota Twins center fielder Byron Buxton got into a row with a steak dinner—and the beefsteak got the better of it. During his meal, the Gold Glove winner cracked a tooth.
Fortunately, he didn't lose it. Buxton's dentist rescued the tooth with a dental procedure that's been around for over a century—a root canal treatment. The dependable root canal is responsible for saving millions of teeth each year.
Dentists turn to root canal treatments for a number of reasons: a permanent tooth's roots are dissolving (a condition called resorption); chronic inflammation of the innermost tooth pulp due to repeated fillings; or a fractured or cracked tooth, like Buxton's, in which the pulp becomes exposed to bacteria.
One of the biggest reasons, though, is advanced tooth decay. Triggered by acid, a by-product of bacteria, a tooth's enamel softens and erodes, allowing decay into the underlying dentin. In its initial stages, we can often treat decay with a filling. But if the decay continues to advance, it can infect the pulp and root canals and eventually reach the bone.
Decay of this magnitude seriously jeopardizes a tooth's survival. But we can still stop it before that point with a root canal. The basic procedure is fairly straightforward. We begin first by drilling a small hole into the tooth to access the inner pulp and root canals. Using special instruments, we then remove all of the infected tissue within the tooth.
After disinfecting the now empty spaces and reshaping the root canals, we fill the tooth with a rubber-like substance called gutta percha. This, along with filling the access hole, seals the tooth's interior from future infection. In most cases, we'll return sometime later and bond a life-like crown to the tooth (as Buxton's dentist did for him) for added protection and support.
You would think such a procedure would get its own ticker tape parade. Unfortunately, there's a cultural apprehension that root canals are painful. But here's the truth—because your tooth and surrounding gums are numbed by local anesthesia, a root canal procedure doesn't hurt. Actually, if your tooth has been throbbing from tooth decay's attack on its nerves, a root canal treatment will alleviate that pain.
After some time on the disabled list, Buxton was back in the lineup in time to hit his longest homer to date at 456 feet on the Twins' Opening Day. You may not have that kind of moment after a root canal, but repairing a bothersome tooth with this important procedure will certainly get you back on your feet again.

We're all interested in how our toothpaste tastes, how it freshens breath or how it brightens teeth. But those are secondary to its most important function, which is how well our toothpaste helps us remove dental plaque, that thin bacterial film on teeth most responsible for both tooth decay and gum disease.
Daily brushing and flossing clear away dental plaque, resulting in a much lower risk for dental disease. But while the mechanical action of brushing loosens plaque, toothpaste helps complete its removal. It can do this because of two basic ingredients found in nearly every brand of toothpaste.
The first is an abrasive (or polishing agent), a gritty substance that boosts the effectiveness of the brushing action (which, by the way, alleviates the need for harmful aggressive brushing). These substances, usually hydrated silica, hydrated alumina or calcium carbonate, are abrasive enough to loosen plaque, but not enough to damage tooth enamel.
The other ingredient, a detergent, works much the same way as the product you use to wash greasy dishes—it breaks down the parts of plaque that water can't dissolve. The most common, sodium lauryl sulfate, a safe detergent found in other hygiene products, loosens and dissolves plaque so that it can be easily rinsed away.
You'll also find other ingredients to some degree in toothpaste: flavorings, of course, that go a long way toward making the brushing experience more pleasant; humectants to help toothpaste retain moisture; and binders to hold bind all the ingredients together. And many toothpastes also contain fluoride, a naturally-occurring chemical that strengthens tooth enamel.
You may also find additional ingredients in toothpastes that specialize in certain functions like reducing tartar buildup (hardened plaque), easing tooth or gum sensitivity or controlling bacterial growth. Many toothpastes also include whiteners to promote a brighter smile. Your dentist can advise you on what to look for in a toothpaste to meet a specific need.
But your first priority should always be how well your toothpaste helps you keep your teeth and gums healthy. Knowing what's in it can help you choose your toothpaste more wisely.
