Mythbusters: Cavity edition: Part 2

- The best cavity prevention is a good oral hygiene routine. TRUE. (Of course.) It may seem like common sense, but regular brushing and flossing is the best way you can prevent cavities. Try to brush your teeth at least twice a day for two minutes each time. Ideally, you should brush your teeth three times a day, for three minutes at a time. You should also floss at least once each day.
- A chipped tooth causes decay. TRUE. If you crack or chip a tooth, you’ve created a prime spot where bacteria can flourish. Over time, these bacteria will cause decay and ultimately a cavity. If you think you may have a chipped tooth, schedule an appointment with your dentist as soon as you can. They can repair it before bacteria have the chance to grow.
- You can keep your fillings for life, without having to have them replaced. Both TRUE and FALSE. If you take good care of an amalgam or composite filling, it can last a lifetime. But if the tooth gets chipped, or if another cavity forms around it, your dentist may need to replace it.
- Sugar is the main cavity causer. Both TRUE and FALSE. (This is another trick one.) Cavities are formed by acid produced from bacteria in your mouth. However, the bacteria feed on carbohydrates in your mouth…like sugar. Anytime you eat something that contains carbohydrates, your body activates the bacteria-producing acid.
- Root canals come from cavities. Both TRUE and FALSE. You need a root canal when the inner part of the tooth is damaged, whether from decay or a fractured tooth. It’s true that an untreated cavity could ultimately lead to nerve damage inside a tooth, and thus lead to the need for a root canal. Bruxism, a term that means clenching and grinding teeth, can also lead to the need for a root canal due to cracks that can be caused from it.
