Just like their name implies, cavities are tiny holes in the enamel and dentin layers of teeth. Cavities are the result of tooth decay, which happens when bacteria invade broken or damaged teeth.
Simple sugars are the main culprits behind cavities. Soda, juice, candy, and similar foods can linger on teeth. The bacteria in your mouth can turn these simple carbs into acids that erode the enamel on your teeth. And a cavity is born.
You might notice that you have a cavity on your own. Many people experience toothache and discomfort when they have a cavity. Your tooth might be especially sensitive to temperature or ache when you eat something sweet.
Sometimes it takes a trip to the dentist to find a cavity. With x-ray imaging the dentist can see cavities between your teeth. They can also use dental equipment to look for soft spots and holes on the tooth’s surface.
Fortunately, dentists can fix cavities with a dental filling. First, the dentist removes the decayed portion of tooth with a small drill. Then they replace the missing part of the tooth with a safe material. Fillings can be made of gold, silver, porcelain, or a composite resin. After a filling, your tooth will feel much better.
