Is sugar the main cause of tooth decay?

No, not necessarily. The main causes of tooth decay is no one drinks water anymore and everyone constantly drinks or snacks. There are no breaks for teeth anymore. Normally, if you eat/drink something your teeth would get a break between meals to neutrilize acid. This does not happen anymore. People drink and eat all day. So, the acid is never neutrilized. Also, lack of proper brushing and flossing causes too much bacteria to be present on the teeth increasing acid output in the mouth and increasing cavities. Sugars, Carbs, or Anything acidic contributes to cavities.

That, and not brushing your teeth properly.
Reply:Yes and not taking really good care of your teeth. It's good to visit the dentist at least twice a year to prevent serious damage to your teeth.
Reply:Not the sugar that causes tooth decay. It's the bacteria that fuels off of sugar that decays your teeth. With proper dental care: such as flossing and brushing, tooth decay can be prevented. When you brush your teeth you want to get all the way to the gums, and move the brush in small circular motions. Mouthwashing after also helps.
Reply:yes, and not flossing or brushing. It's mostly from soda I think because soda has so many bad things including metal..
Reply:Yes basically in a nut shell. It has to do with fermentable carbohydrates (which is also sugar). Anything you eat causes the pH in the mouth to drop causing teeth to be attacked by acid.
Reply:Yes definitely even if your the best brusher and flosser in the world if there is alot of suger in your diet you will have tooth decay
