If your dentist found tooth decay on your last visit, you might have been surprised. But tooth decay doesn't occur suddenly—it's a process that takes time to unfold.
It begins with bacteria—too many, that is. Bacteria naturally live in the mouth, but when their populations grow (often because of an abundance of leftover sugar to feed on) they produce high amounts of acid, a byproduct of their digestion. Too much acid contact over time softens and eventually erodes tooth enamel, making decay easier to advance into the tooth.
So, one important strategy for preventing tooth decay is to keep your mouth's bacterial population under control. To do that, here are 4 common-sense tactics you should perform between dental visits.
Practice daily hygiene. Bacteria thrive in dental plaque, a thin film of food particles that builds up on teeth. By both brushing and flossing you can reduce plaque buildup and in turn reduce disease-causing bacteria. In addition, brushing with a fluoride toothpaste can also help strengthen tooth enamel against acid attacks.
Cut back on sugar. Reducing how much sugar you eat—and how often –deprives bacteria of a prime food source. Constant snacking throughout the day on sweets worsens the problem because it prevents saliva, the body's natural acid neutralizer, from reducing high acid levels produced while eating. Constant snacking doesn't allow saliva to complete this process, which normally takes about thirty minutes to an hour. To avoid this scenario, limit any sweets you eat to mealtimes only.
Wait to brush after eating. Although this sounds counterintuitive, your tooth enamel is in a softened state until saliva completes the acid neutralizing process previously described. If you brush immediately after eating you could brush away tiny particles of softened enamel. Instead, rinse your mouth out with water and wait an hour for saliva to do its work before brushing.
Boost your saliva. Inadequate saliva flow could inhibit the fluid's ability to adequately neutralize acid or provide other restorative benefits to tooth enamel. You can improve flow with supplements or medications, or by drinking more water during the day. Products with xylitol, a natural sugar alternative, could give you a double benefit: chewing gums and mints containing it could stimulate more saliva flow and the xylitol itself can inhibit bacterial growth.
You don’t have to be a dental professional to appreciate a beautiful smile. Likewise, you’ll also know when something’s not quite right with one.
Such can be the case when a tooth fails to erupt properly, causing most or all of the crown to remain below the gum line, a condition known as impaction. Upper canines (or “eyeteeth,” for their location in the arch under the eyes) are especially susceptible to impaction: located on either side of the lateral incisors, which are on either side of the central incisors (the two center front teeth).
The upper canines are important both for function and appearance. Working with their lower counterparts they help cut through food as we chew, so you lose some of that efficiency when they don’t erupt properly. Impacted teeth are susceptible to abscesses and cysts, and can impinge upon and damage the roots of other teeth. And just as importantly, their absence also disrupts the smile as nearby teeth tend to move or “drift” toward the open space.
Rather than remove the impacted canines as is often done with back teeth, it may be more advantageous for both function and appearance to “coax” them into full eruption. This requires first pinpointing their exact location below the gums using x-rays or cone beam 3-D imaging.
If the teeth are in reasonably good position we must first prepare them for orthodontic treatment by surgically exposing the crown from the gums and bonding a small bracket to it. We then attach a small gold chain to the bracket that extends outside of the gums when we suture them back into place. The chain is attached to orthodontic hardware that exerts pressure on the impacted tooth for several months to “pull” it out into the arch.
This procedure has the best chance of success if undertaken before the end of jaw development in early adulthood. Otherwise, it may be better to remove the impacted canines and replace them with dental implants, followed by orthodontic treatment of other teeth to restore their proper position and bite relationships. In either case, your impacted upper canines don’t have to be a problem — we can restore both your mouth function and your smile.
