Human beings have known for millennia the importance of keeping teeth clean. Although we've only come to more fully understand dental plaque's role in dental disease in the last century, our ancestors seemed to know instinctively this gritty biofilm on teeth had to go.
People from the past once used a variety of substances like ground oyster shells or leftover fire ashes to remove plaque from their teeth. Today, most of the world has replaced these substances with toothpaste, a mainstay of daily oral hygiene.
So, why is toothpaste better than other substances used in the ancient past? Besides the many other ingredients found in the typical tube of toothpaste, here are the top 3 that make it the ultimate tooth cleaner.
Abrasives. While your toothbrush does most of the mechanical work loosening plaque, toothpaste has ingredients called abrasives that give an added boost to your brushing action. The ideal abrasive is strong enough to remove plaque, but not enough to damage tooth enamel. If you look at your toothpaste's ingredient list, you'll probably see an abrasive like hydrated silica (made from sand), hydrated alumina, calcium carbonate or dicalcium phosphates.
Detergents. Your toothpaste's foaming action is a sign of a detergent, which helps loosen and break down non-soluble (not dissolvable with plain water) food substances. While similar to what you may use to wash your clothes or dishes, toothpaste detergents are much milder, the most common being sodium lauryl sulfate found in many cosmetic items. If you have frequent canker sores, though, sodium lauryl sulfate can cause irritation, so look for a toothpaste with a different detergent.
Fluoride. The enamel strengthening power of fluoride was one of the greatest discoveries in dental care history. Although not all toothpastes contain it, choosing one with fluoride can improve your enamel health and help protect you from tooth decay.
These and other ingredients like binders, preservatives and flavorings, all go in to make toothpaste the teeth-cleaning, disease-fighting product we've all come to depend upon. Used as part of daily oral hygiene, toothpaste can help brighten and freshen your smile, and keep your teeth and gums healthy.

A beautiful smile is a balanced smile, especially in regard to your gums. A normal smile usually shows 4 mm or less of gum tissue along with about 10 mm of tooth length. But if your gums show more than that, your smile may seem too gummy. In terms of perceived balance, this could detract from your smile's attractiveness.
Fortunately, you don't have to live with a gummy smile—there are various ways to correct or minimize its effect. First, though, we'll need to determine the underlying cause before deciding on the best treatment. And, there are several possible causes, the obvious being too much gum tissue present. Teeth that appear shorter due to wear or incomplete eruption could also make the gums appear larger.
We may be able to correct these size problems by surgically removing and reshaping excess gum tissues and possibly the underlying bone to reveal more of the teeth. We can also bond composite resins or porcelain veneers to shorter teeth to make them appear larger.
But not all gummy smile problems pertain directly to the teeth and gums; instead, it could be your upper lip moves too far up as you smile (hypermobility). Or, your upper jaw may be too long for your face, which can also cause too much of the gums to show during smiling.
With upper lip hypermobility, we may be able to inhibit the lip muscles' movement temporarily with Botox injections that partially paralyze the muscles (the effect eventually wears off, so this treatment will need to be repeated). A periodontist, an oral surgeon, or a plastic surgeon could also permanently alter the upper lip movement through a surgical procedure. Surgery may also be necessary for an abnormally long upper jaw: orthognathic surgery re-positions the jaw to the skull, which can lessen the amount of gums showing.
If your smile is too gummy, we can transform it. But first, let's find out what the real cause is with a comprehensive dental examination. Once we know, we can better advise you on the best way to bring beautiful balance to your smile.

A recent episode of “America’s Got Talent” featured an engaging 93-year-old strongman called The Mighty Atom Jr. The mature muscleman’s stunt: moving a full-sized car (laden with his octogenarian “kid brother,” his brother’s wife, plus Atom’s “lady friend”) using just his teeth. Grinning for host Howie Mandel, Atom proudly told the TV audience that his teeth were all his own; then he grasped a leather strap in his mouth, and successfully pulled the car from a standstill.
We’re pleased to see that the Atom has kept his natural teeth in good shape: He must have found time for brushing and flossing in between stunts. Needless to say, his “talent” isn’t one we’d recommend trying at home. But aside from pulling vehicles, teeth can also be chipped or fractured by more mundane (yet still risky) activities — playing sports, nibbling on pencils, or biting too hard on ice. What can you do if that happens to your teeth?
Fortunately, we have a number of ways to repair cracked or chipped teeth. One of the easiest and fastest is cosmetic bonding with tooth-colored resins. Bonding can be used to fill in small chips, cracks and discolorations in the teeth. The bonding material is a high-tech mixture of plastic and glass components that’s extremely lifelike, and can last for several years. Plus, it’s a procedure that can be done right in the office, with minimal preparation or discomfort. However, it may not be suitable for larger chips, and it isn’t the longest-lasting type of restoration.
When more of the tooth structure is missing, a crown (or cap) might be needed to restore the tooth’s appearance and function. This involves creating a replacement for the entire visible part of the tooth in a dental lab — or in some cases, right in the office. It typically involves making a model of the damaged tooth and its neighbors, then fabricating a replica, which will fit perfectly into the bite. Finally, the replacement crown is permanently cemented to the damaged tooth. A crown replacement can last for many years if the tooth’s roots are in good shape. But what if the roots have been dislodged?
In some cases it’s possible to re-implant a tooth that has been knocked out — especially if it has been carefully preserved, and receives immediate professional attention. But if a tooth can’t be saved (due to a deeply fractured root, for example) a dental implant offers today’s best option for tooth replacement. This procedure has a success rate of over 95 percent, and gives you a natural looking replacement tooth that can last for the rest of your life.
So what have we learned? If you take care of your teeth, like strongman Atom, they can last a long time — but if you need to move your car, go get the keys.
