### Understanding Black Spots on Teeth Even if you brush and floss diligently, you might still notice spots on your teeth. While some discoloration from foods and drinks is common and not usually a cause for concern, a black or dark spot could indicate a more serious issue like tooth decay. #### Causes of Black Spots 1. **Plaque Build-Up**: Food and bacteria can accumulate on your teeth, forming a sticky substance known as plaque. If plaque is not removed, the acids in it can erode your tooth enamel, leading to cavities. 2. **Tooth Decay**: When tooth decay progresses, it can penetrate the enamel and reach the soft core of the tooth, causing inflammation or infection of the pulp. 3. **Staining**: Certain foods, drinks, and nicotine products can stain your teeth, causing dark spots. #### Symptoms of a Cavity - Toothache - Sensitivity to hot, cold, or sweet foods - Visible holes or pits in your teeth - Pain when biting down #### Treatment Options - **Fillings**: Recommended for cavities that are closer to the surface and do not affect the tooth pulp or nerves. - **Root Canal**: Needed when decay reaches the pulp inside your tooth, causing inflammation or infection. - **Stain Removal**: Both at-home and in-office treatments can help remove discoloration caused by staining. #### Prevention Tips - Brush and floss regularly - Avoid foods and drinks that stain your teeth - Visit your dentist for regular check-ups If you notice a black or dark spot on your tooth, it’s important to consult your dentist. They can determine the cause and provide appropriate treatment options.
