Refined sugar is a prime food source for disease-causing oral bacteria. As bacteria consume sugar they produce high levels of acid that over time can erode enamel and leave a tooth vulnerable for decay.
The solution to stopping this vicious process is simple: cut back on eating refined sugar. The reality, though, is a bit more complicated. Many of us seem genetically hard-wired with a “sweet tooth,” perhaps a remnant of our early ancestors' sense that sweet foods were a safe means to obtain energy.
Food manufacturers likewise don't help with making this dietary change — the number of items with added sugar has ballooned over the last several decades. We can trace a lot of this back to the unintended consequences of past government guidelines that called for removing fat from processed foods. But this also removed flavor, so manufacturers began adding sugar (under a myriad of names) to compensate.
Sugar consumption is now a hot health topic for its suspected connection with inflammatory diseases like diabetes and cardiovascular disease, as well as dental health. We now have a love-hate relationship with sugar — we want to show it the door but we can't quite bring ourselves to let it go.
The situation has created a market for artificial sweeteners. The amount and types of sugar alternatives has exploded since saccharine first emerged in the early 1960s. With these increased choices, though, there have also been increased concerns over their health impact, including in the mouth.
This concern has prompted numerous research studies. The conclusion: artificial sweeteners don't adversely affect the health of most people. And, from a dental perspective, artificial sweeteners can have a positive impact on teeth and gum health because unlike refined sugar they don't promote oral bacterial growth.
In fact, one particular sweetener may be even more beneficial to your teeth: xylitol. This sweetener, which comes from a sugar alcohol that oral bacteria can't digest, is often found in chewing gums, hard candies or mints. Â In effect, xylitol “starves out” bacteria to help prevent tooth decay.
From a dental perspective, replacing sugar with an artificial sweetener (especially xylitol) can be advantageous. And less sugar could mean more good news after your next dental checkup.

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!
