For some kids, having a cavity or two is just part of growing up. Not for Giuliana Rancic. When she was a child, the TV personality didn't have a single cavity — and she still doesn't. But for her husband Bill, co-star of the Style Network reality show Giuliana and Bill, it was a different story. A cavity-prone kid, he was never certain what a visit to the dentist might hold in store. “I can still remember the anticipation,” he recently told Dear Doctor magazine. “I always hoped I would get out of the checkups without a cavity!”
Why do some people get more cavities than others? There are a number of factors at work, but to understand it better, let's look at how tooth decay occurs.
How Cavities Form
Cavities — also called dental caries — are small pits or holes in the teeth that are caused by tooth decay. Tooth decay itself is a chronic disease that can flare up when plaque isn't kept under control. A thin, bacteria-laden film, plaque sticks to tooth surfaces both above and below the gum line, and can build up in the absence of effective oral hygiene.
Of course, everyone has bacteria in their mouth, both “good” and “bad” (pathogenic) types. But when the bad guys outnumber the good, trouble can start. When you consume sweets, plaque bacteria process the sugars and release acid as a byproduct. The acid eats into tooth surfaces, causing decay — and cavities that need filling. Left untreated, decay can work its way into the tooth's pulp, resulting in infection and pain. Eventually, treatment might involve a root canal — or, in the worst case, extraction.
What can you do if you seem to be prone to cavities? One effective way to fight tooth decay is by maintaining good oral hygiene. Brush at least twice daily, for at least two minutes each time. Use a soft-bristled brush and a dab of fluoride toothpaste to clean all around your teeth. Most importantly, floss above and below the gum line, every day. And just as important, don't forget to have regular dental checkups every six months.
A Healthy Balance
Another cavity-fighting strategy is eating a balanced diet. Avoid soda, sugary “energy” drinks and sweet treats — but if you choose to consume sugar, have it with meals instead of between meals. This will give your saliva, which has natural cavity-fighting properties, a chance to work.
“It's all about maintaining a healthy balance,” Giuliana told Dear Doctor. And Bill agrees: “I love nuts and fruit for a healthy snack,” he said, adding that he's meticulous about brushing and flossing. And when the couple smiles, you can see how those healthy habits pay off.

In a recent study, 92% of dental implants were found to have survived the twenty-year mark — an impressive track record for any dental restoration.
Still, implants do fail, although rarely. Of those failures, tobacco smokers experience them twice as often as non-smokers. The incidence of early failure (within the first few months after implantation) is even higher for smokers.
Early implant failure typically happens because the titanium implant and the surrounding bone fail to integrate properly. Titanium has a natural affinity with bone — the surrounding bone will attach and grow to the titanium in the weeks after surgery, forming a strong bond. An infection around the implant site, however, can inhibit this integration and result in a weaker attachment between bone and implant. This weakness increases the chance the implant will be lost once it encounters the normal biting forces in the mouth.
Smokers have a higher risk of this kind of infection because of the way tobacco smoke alters the environment of the mouth. Inhaled smoke burns the mouth’s top skin layers and creates a thick layer of skin called keratosis in its place. Smoke also damages salivary glands so that they don’t produce enough saliva to neutralize the acid from food that’s left in the mouth after eating. This creates an environment conducive to the growth of infection-causing bacteria. At the same time, the nicotine in tobacco can constrict the mouth’s blood vessels inhibiting blood flow. The body’s abilities to heal and fight infection are adversely affected by this reduced blood flow.
The best way for a smoker to reduce this early failure risk is to quit smoking altogether a few weeks before you undergo implant surgery. If you’re unable to quit, then you should stop smoking a week before your implant surgery and continue to abstain from smoking for two weeks after. It’s also important for you to maintain good brushing and flossing habits, and semi-annual dental cleanings and checkups.
Although smoking only slightly raises the chances of implant failure, the habit should be factored into your decision to undergo implant surgery. Quitting smoking, on the other hand, can improve your chances of a successful outcome with your implants — and benefit your life and health as well.
