Anatomy of a Cavity


How the DDS Responds to Your Mouth's SOS

Thankfully, there are a few different ways to combat the results of this offensive drive. If the bacteria and acids have managed to create only a small hole in your tooth, your dentist will most likely "drill and fill"—that is, remove the old portion of the tooth and replace it with a filling.

If the cavity is more extensive, dentists will place a cap, called a crown, over the tooth to restore it to its normal size and shape. And if the diggin' didn't stop there? The decay can spread into the tooth pulp and become infected, such that the dentist may call for a root canal. This procedure involves removing the tooth's pulp and the nerve, followed by a sealing of the roots.

New technologies are in the works to enhance the cavity detection and treatment process. Irwin Smigel, D.D.S., a dentist in New York City, mentions a detection method involving the use of a special fluorescent light that can recognize the development of decay before "it really gets into the teeth," he says.

If the fluorescent-light method does indeed turn up evidence of decay, dentists can then apply sealants or utilize fluoride to prevent the development of cavities. Researchers are also working on a "smart filling" designed to slowly release fluoride in order to prevent further tooth decay in a small cavity and surrounding teeth. Although these two technologies are in the developmental stages, these detection and treatment resources could bring down cavity counts significantly over the years.

The Best Defense Against Plaque Attack

If that all sounds a bit like tactical munitions planning, here's the good news: With solid oral hygiene habits (meaning: brushing, flossing, and rinsing with a fluoride mouthwash), tooth decay and cavities are preventable. According to Nicole Holland, D.D.S., it's all about proper and consistent maintenance.

"I tell my patients that what's important is your individual home care in combination with the professional care you receive when you go into the office," she says. It's a relationship between the two prongs of care. "You can't choose one or the other." Most dentists recommend you get a professional cleaning and exam every six months.

Even though we've all had it drilled into us that we should brush our teeth at least twice a day (morning and evening), many people have a tendency to skip the pre-bed brush after a long day. Guilty as charged? Heed this: As Smigel points out, brushing before sleep is the time that counts the most when it comes to cavity prevention.

"During the day we swallow at least 2,000 times. Saliva in the mouth is constantly cleaning the teeth, which helps prevent cavities," Smigel says. "At night we swallow only about 20 times." An untended mouth in the evening leads not only to dragon breath in the morning, but an accumulation of plaque overnight. Holland adds that any time your mouth feels dry -- for instance, after a workout or during an illness -- it's important to hydrate in order to activate the production of saliva.

Not All Cavity Culprits Are Created Equal

Don't be fooled: Those pretzel M&M's and other sugary foods aren't the only offenders. Simple carbohydrates like potato chips, bagels, and white bread are all converted into acid in the mouth. Additionally, Holland says, "It's not just what is going into your mouth; it's also the frequency. You don't want to be constantly snacking. You don't want that constant exposure to the carbs -- or the bacteria will just go to town."

Addicted to chewing gum? You're in luck if what you're chomping on contains xylitol. The plant-derived substance is a sweetener in sugar-free gums and slows the growth of the bacteria that causes cavities. The American Dental Association (ADA) publishes a list of gums that bear their seal of approval.
