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.

You could have an unattractive smile because of a chipped tooth or one slightly out of alignment. Or, it could be both of the above, plus some heavy staining to boot. Correcting each flaw individually might require a combination of different methods like orthodontics or porcelain crowns, which can take an extended period of time to complete.
But you may be able to correct numerous smile flaws with just one method—and in no more than a couple of treatment visits. It's called direct veneers.
Unlike regular veneers, direct veneers don't require a dental technician to craft a thin porcelain shell to bond over teeth. Rather, a dentist applies a tooth-colored material called composite resin to the problem teeth and "sculpts" an entirely new look that can correct multiple dental flaws at one time.
The dentist usually begins the process by creating a model ("wax-up") of proposed changes based on physical impressions of the jaw and teeth. Both dentist and patient can study the model and modify it if necessary, when finalizing the treatment plan.
At a subsequent appointment, the dentist prepares the tooth surface for bonding by removing a thin layer of tooth enamel, then shapes the teeth to better accommodate the composite resin. This tooth prep is similar to that done with traditional veneers, so it's permanent—the teeth will require some form of restoration from then on.
After applying an etchant and a bonding agent, the dentist applies the composite resin in small amounts, hardening each layer with a special light before applying the next one. With each subsequent layer, the dentist sculps the composite material to eventually resemble the wax-up model.
After completing the composite application, the dentist then uses hand tools and a dental drill to complete shaping, as well as an abrasive strip between teeth to aid future flossing. After just a few hours, the transformation is complete.
Direct veneers are durable, but not to the same extent as regular veneers or other cosmetic enhancements. They can also pick up stains over time, and may require re-treatment at some point. Still, direct veneers are a cost-effective way to improve the appearance of teeth with multiple flaws that could radically change your smile for the better.
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.

Kill Bill fans have been pressing for a third installment of the stylized revenge tale since Kill Bill, Volume 2 hit the theaters in 2004. Finally, filmmaker Quentin Tarantino is talking about the long-awaited Volume 3 as if it might soon become a reality. The third movie in the franchise would most likely focus on the now-grown daughter of the character played by Vivica A. Fox in the first two. Vivica recently made known that should Kill Bill, Volume 3 go into production, she thinks 24-year-old actress and singer Zendaya would be perfect for the role.
Although Zendaya is a few inches taller than Vivica, the two women have a few things in common. Besides being talented movie and television actresses who have won awards for their roles, they both have camera-ready smiles. And both Vivica and Zendaya can thank their dentists for helping their smiles be their best.
In 2016, Vivica told Dear Doctor magazine that her smile needed a boost, so she opted for dental veneers to correct gaps between her teeth—and she's very happy with them. “I love my veneers!” she exclaimed. Zendaya also had help in achieving her Hollywood-perfect smile. In 2011, early in her career on the Disney channel, she wore clear orthodontic aligners to straighten her teeth. To further perfect her smile, she visited her dentist for professional teeth whitening in 2016, inviting a film crew along to show how easy and effective in-office tooth whitening is.
But you don't have to be a celebrity to enjoy smile-enhancing dental treatments. They are great options for anyone who wants to improve the look of their smile.
Teeth whitening. If your teeth are looking yellowed, in-office whitening can make them up to 10 shades brighter in one visit! Some people prefer professional at-home whitening kits, which produce great results more gradually.
Bonding or veneers. For small chips and cracks, cosmetic bonding can cover flaws by adding layers of a tooth-colored material over the tooth. For bigger flaws, heavy discoloration or gaps between teeth as Vivica had, dental veneers may be the answer. These custom-made thin porcelain shells cover the front-facing surface of the tooth, hiding imperfections to give anyone a Hollywood smile.
Orthodontics. Crooked teeth can detract from the look of a smile. While traditional braces are an option, many people with mild to moderate alignment issues find removable clear aligners the perfect way to get the smile they desire with minimal impact on their daily activities. Clear aligners are very subtle and can be removed for eating and cleaning as well as for special occasions—or for filming scenes, as Zendaya knows.
Contact us or schedule an appointment for a consultation to see if professional teeth whitening, cosmetic bonding or veneers, orthodontics, or another dental treatment could enhance your smile.

Although we've known for some time how tooth decay forms, it's still prevalent across the population—even more so than cancer or heart disease. Along with gum disease, it's a leading cause of tooth loss.
Fortunately, our knowledge about tooth decay has grown considerably, to the point that we now recognize a number of risk factors that make it more likely a person will develop this disease. By first identifying them in individual patients, we can take steps to address them specifically to reduce the chances of this destructive disease.
Genetics. Researchers have identified around 40 to 50 genes that can influence cavity development. The best way to assess your genetic risk is through family history—if numerous close family members contend with tooth decay, your risk may be high. If so, it's important to be extra vigilant with addressing other areas over which you have more control.
Saliva. Cavities are directly caused by oral acid, a byproduct of bacteria, that can erode tooth enamel over prolonged contact. This is minimized, though, through a normal saliva flow that neutralizes acid and helps remineralize enamel. But poor saliva production can slow acid neutralization. You can improve your saliva flow by drinking more water, changing medications or using saliva-boosting products.
Oral hygiene. You can reduce bacteria (and thus acid) by removing their "room and board"—dental plaque. This accumulating film of food particles harbors the bacteria that feed on it. Daily brushing and flossing, accompanied by regular dental cleanings, effectively removes dental plaque, which in turn lowers the levels of oral bacteria and acid.
Dental-friendly diet. Even if you diligently address the previous risk factors, your diet may fight against your efforts. Diets high in processed and refined foods, especially sugar, provide abundant food sources for bacteria. On the other hand, a diet primarily of whole foods rich in vitamins (especially D) and minerals like calcium and phosphorous strengthen teeth against decay.
Preventing tooth decay isn't a "one-size-fits-all" approach. By identifying your own particular risk, we can craft a care strategy that can be your best defense against this destructive dental disease.
