Fountain Valley Dentist Says: 15 Myths and Facts About Cavities

Dr. Peter Hagen, your Fountain Valley dentist, found this article about myths and facts about cavities that he thinks would be particularly useful for his clients and readers. Tooth decay is one of the biggest problems facing people today; It is good to know what is truth and half truth about this common oral health problem:
Check the myths and facts below to find out how cavities are caused, prevented, and treated. 
1. Sugar Is the Prime Cause of CavitiesMyth, but it's almost a fact.  
The truth is, acid produced by bacteria in your mouth is the cause of cavities, says Kimberly A. Harms, DDS, an American Dental Association consumer advisor and former president of the Minnesota Dental Association. However, these bacteria are triggered to make acid when you eat anything with carbohydrates -- and sugar is a carb.  Rice, potatoes, bread, fruits, and vegetables are also carbs. 
Once the acid eats into your tooth, the bacteria “have a nice little hole to live in where your toothbrush and floss can’t reach,” says Harms. The bacteria continue to metabolize carbs and produce acids -- and your cavity just keeps getting bigger. 
Here’s an important fact. It’s not the amount of carbs you eat that causes tooth decay, but the length of time your teeth are exposed. If you eat a lot of carbs for lunch, that’s one big exposure. But if you spend the day sipping sugary drinks, that’s continuous exposure -- and much more unhealthy for your teeth. 
“We have a saying,” says Harms. “Sip all day and get decay.”

2. Exposure to Acidic Foods, Like Lemons, Causes Tooth Decay 
Fact. Acidic foods such as lemons, citrus juices, or soft drinks don’t cause cavities, but they may be putting your enamel in danger. 
"Acids can tear down your enamel and weaken your tooth," says Harms. “If you lose the enamel's protection and expose the underlying dentin, your tooth is now more prone to decay.” 
3. Kids Are a Lot More Likely to Get Cavities Than Adults 
Myth. With the help of sealants, fluoridated water, and preventive care, “we’ve actually cut decay in school-aged children by half in the last 20 years,” says Harms.However, there’s been an increase in cavities in senior citizens “because they have some unique circumstances,” she says. Some medicines dry out the mouth, for example, reducing salvia. Saliva is vital in fighting tooth decay because it helps neutralize acids, has a disinfectant quality, washes away bacteria, and helps prevent food from sticking to your teeth.
