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.

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.

Mike Tyson made a splash when he faced off against sharks during the Discovery Channel's Shark Week 2020. But there's bigger news for fans of the former undisputed world heavyweight champion: After a 15-year absence, he will enter the ring again for two exhibition matches in the Fall. However, it's not just Tyson's boxing action that made news during his 20-year career. His teeth have also gotten their fair share of press.
Tyson used to be known for two distinctive gold-capped teeth in the front left side of his mouth. He made headlines when he lost one of the shiny caps—not from a blow by a fellow pugilist but from being headbutted by his pet tiger as Tyson leaned in for a kiss. Tyson's teeth again garnered attention when he had his recognizable gold caps replaced with tooth-colored restorations. But the world champion may be best known, dentally at least, for his trademark tooth gap, or “diastema” in dentist-speak. Several years ago, he had the gap closed in a dental makeover, but he soon regretted the move. After all, the gap was a signature look for him, so he had it put back in.
That's one thing about cosmetic dentistry: With today's advanced technology and techniques, you can choose a dental makeover to suit your individual taste and personality.
An obvious example is teeth whitening. This common cosmetic treatment is not a one-size-fits-all option. You can choose whether you want eye-catching Hollywood white or a more natural shade.
If your teeth have chips or other small imperfections, bonding may be the solution for you. In dental bonding, tooth-colored material is placed on your tooth in layers and then hardened with a special light. The material is matched to your other teeth so the repaired tooth fits right in. This procedure can usually be done in just one office visit.
For moderate flaws or severe discoloration, porcelain veneers can dramatically improve your appearance. These thin, tooth-colored shells cover the front surface of the tooth—the side that shows when you smile. Veneers are custom-crafted for the ideal individualized look.
Dental crowns can restore single teeth or replace missing teeth as part of a dental bridge. Again, they are manufactured to your specifications. With restorations like crowns and veneers, the smallest detail can be replicated to fit in with your natural teeth—even down to the ridges on the tooth's surface.
And if, like Mike Tyson, you have a gap between your teeth that makes your smile unique, there's no reason to give that up if you opt for a smile makeover. Whether you would like a small cosmetic enhancement or are looking for a more dramatic transformation, we can work with you to devise a treatment plan that is right for you.

Are your stained teeth bumming you out? There's good news—you can transform that dull and dingy smile yourself with a tooth whitening product.
There are dozens of over-the-counter whitening kits that allow you to brighten your own smile. Although not as controlled and long-lasting as a dentist's professional whitening, these DIY kits can still give you effective results.
But since these products involve chemical solutions that bleach tooth enamel, there's a common concern about their safety. Could you be harming your teeth by using a home whitening kit?
The answer is no—as long as you follow the manufacturer's directions for using the product. These kits have been formulated with a lower percentage of bleaching agent (usually 10% carbamide peroxide) than whitening solutions used by dentists. They've also been subjected to several clinical studies gauging both their effectiveness and safety.
That said, though, exceeding a product's recommended directions and frequency of use could cause you problems. If not used properly, a bleaching solution can erode tooth enamel—and this protective tooth layer doesn't grow back! As long as you whiten "within the lines," so to speak, you shouldn't encounter this kind of situation.
With that said, though, there are good reasons to consult your dentist before using a whitening product, or have them perform the whitening for you.
For one thing, an over-the-counter whitening product won't work if the staining originates from inside a tooth. It's wise, then, to have a dental examination first before using a whitening product to uncover this or any other underlying dental problems that should be addressed first.
You may also find a professional whitening will give you a more desirable result. A stronger professional bleaching solution under a dentist's expert control can produce a brighter, longer lasting smile than a home use product. A dentist may also be able to control the level of brightness better to help you achieve the smile effect you desire, from subtle white to ultra-bright.
Whichever way you go, your dentist can advise you on your options and make sure your teeth are in good shape for whitening. The end result can be a brighter smile—and a brighter mood.

Most of what goes on inside our mouths—good or bad—is fairly predictable. But every now and then, people encounter something out of the ordinary. A good example is lichen planus.
Lichen planus are rare skin lesions that can occur on various parts of the skin, including inside the mouth. The name comes from their lacy appearance, which resembles a fungus that grows on rocks or trees called lichen.
Being similar in appearance, though, is all that lichen planus has in common with its fungal namesake. It's believed that the sores are caused by a reaction of the immune system mistaking some of the body's cells as foreign.
But don't let the exotic sounding name alarm you—true lichen planus is considered a benign mouth sore. You may not even realize you have it until your dentist notices and points it out. But the lesions can sometimes cause mild pain or burning, especially if they occur near the gums or if you indulge in spicy or acidic foods.
As we said, these lesions aren't considered dangerous. But in a small number of cases, oral cancer was found to develop later. It's unclear whether the lesions were related to the cancer, or if what were diagnosed as lichen planus lesions were actually pre-cancerous cells mimicking the appearance of the benign sore.
In any event, your dentist will probably continue to monitor the lesions and possibly conduct regular oral cancer screenings to be on the safe side. You may also want to stop using tobacco or alcohol products to further decrease your risk of oral cancer.
As to managing lichen planus, it starts with a daily habit of brushing and flossing. You'll also want to avoid spicy or acidic foods like citrus fruits, tomatoes, peppers or caffeinated drinks, especially during flareups. If the lesions are causing discomfort, your dentist may also prescribe a topical steroid to apply to them.
Since it's quite possible you won't know if you have lichen planus (as well as other types of mouth sores) unless your dentist observes them, you should keep up regular dental visits. Having your dentist check your entire mouth, not just your teeth and gums, will help both of you stay on top of your oral health.
