3WaystoReducetheBacteriainYourMouththatCauseToothDecay

Tooth decay doesn’t suddenly appear out of the blue. Cavities and other damage are the result of a long process that begins with bacteria living in a thin biofilm on tooth surfaces known as plaque. These bacteria thrive on sugars from leftover food in your mouth and then produce acid as a waste product. Chronic high levels of acid cause your enamel, the protective layer of your teeth, to soften and erode.

While there are treatment options at each stage of decay — including crowning or even tooth replacement — the best approach is to try to prevent plaque buildup that supports disease-causing bacteria. Here are 3 of the best ways you can do that.

Brush and floss daily. It usually takes 12-24 hours for enough plaque buildup to support bacteria. By brushing and flossing at least once a day, you can remove most of this buildup, with twice a year dental cleanings to remove hard to reach plaque you may have missed. Be sure to use fluoride toothpaste to help strengthen enamel against high acid. And wait a half hour to an hour after eating before brushing to give saliva time to reduce the acid level in your mouth.

Cut back on sweets. You’re not the only one who loves sugary snack foods — so do oral bacteria. The more sugar and other carbohydrates they feast on, the more they produce acid. The best approach is to cut out sugar-rich snacks altogether and instead snack on fresh fruits, raw vegetables or dairy products. Limit sweet treats to meal times.

Use decay-fighting supplements. Your mouth and hygiene efforts may need a little assistance, especially if you have low saliva flow. You can boost this with an artificial saliva supplement as well as with products containing xylitol, an alcohol-based sugar. Xylitol also has an added benefit in the fight against decay because it inhibits bacterial growth. And be sure to talk with us first before taking any dental supplement.

AirAbrasionCouldbeaMorePleasantAlternativetotheDentalDrill

While it may not be one of your favorite features in the dental office, the dental drill is nevertheless necessary for treating problem teeth. It’s used primarily for removing decayed or damaged structure and preparing a tooth for fillings or other restorations.

Dental drills have been used for decades and are quite effective — but they have their drawbacks. Their rotating burrs often remove portions of healthy tooth structure along with decayed material. Friction from the drill action can cause discomfort, so local anesthesia is usually needed. Drills can also emit a high-pitched machine noise that’s unsettling to many patients.

There’s a growing alternative to the drill, known as air abrasion. Although the technology has been around since the 1950s, the development of new suction pumps that capture the resulting dust from its use has made it more palatable as an option to the traditional drill.

Also known as particle abrasion, the technique uses a pressurized stream of fine particles (usually aluminum oxide, an abrasive powder) directed at teeth to wear away (abrade) the tooth’s structural surface. We can be quite precise in the amount of surface material removed, so it’s useful for diminishing stains or roughing the surface for bonding materials like composite resin. We’re also able to remove decayed material with very little impact on surrounding healthy structure, and you may not need anesthesia during the procedure.

While this quiet alternative to the noisier drill is quite versatile, it does have its limitations. It’s not that efficient for preparing larger cavities for restoration or for removing older amalgam fillings. The teeth to be treated must be carefully isolated to prevent the fine particle dust produced from being swallowed by the patient or spread into the air. High-volume suction equipment is a must or the procedure will create a “sandstorm” of particles in the room.

Still, for situations suited to it and with proper isolation measures, air abrasion can be effective and comfortable. If the technology continues to improve, the dental drill may soon become a relic of the past.

JamieFoxxChipsaTooth-ThisTimebyAccident

Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.

“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…

For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.

When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.

A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.

But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.

Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!
