Myth 1: Sugar is the only thing that causes cavities
In fact the acid produced by bacteria cause cavities. The bacteria digest the sugar we eat. Any carb you eat can contribute to bacteria produced acid such as sugar from fruit, rice, and bread.
Fact 1: Acid causes tooth decay
Consuming acidic foods and drinks can erode the enamel (outer covering of teeth) similar to the way bacterial acid wears the teeth.
Myth 2: Kids get more cavities than adults
While there has been a decrease in childhood cavities since the public health initiative to put fluoride in drinking water, there has been an increase in cavities in the elderly due to medications that dry the mouth. One of saliva’s main benefits is to protect the teeth from acid.
Myth 3: Putting aspirin next to a tooth will help a toothache
Aspirin must get into the bloodstream to exert its effects. The acidity of the aspirin tablet could cause an ulcer on your gums.
Myth 4: You will know when you have a cavity
When the cavity gets so big it reaches the pulp you will probably have intense pain. However, it’s best to get a cavity treated when it is small and before the pain starts so that as much of your natural tooth as possible is still healthy.
Fact 2: Once a tooth is treated the decay stops
Before your dentist puts in a filling he makes sure all of the cavity and diseased tooth is removed so that it is clean before the filling. However, after a filling is placed a new cavity can initiate if diet and home care aren't improved.
Fact 3: Cavities are most likely between your teeth
Bacteria love to hide where the toothbrush can’t reach, especially between your teeth. Use floss, mouthwash, and interdental brushes to get the difficult spots between teeth.
Myth 5: Cavities are the only reason for root canals
Injury to the tooth can also require a root canal
Fact 4: You have to brush and floss to prevent cavities
Definitely! Without excellent home care you won’t be able to remove food, plaque, and bacteria. If you don’t like to floss try an interdental brush or a toothpick.
