### What Causes Cavities and How to Prevent Them Cavities are caused by tooth decay, which damages the tooth's outer layer (enamel) and inner layer (dentin). Symptoms include toothache, sensitivity, visible holes, and stains. Decay occurs when bacteria in the mouth convert carbohydrates from foods like bread, milk, and candy into acids. These acids form plaque, which clings to teeth and dissolves enamel, creating cavities. Cavities can affect anyone, including adults and seniors, due to factors like gum recession and sugary diets. To prevent cavities, follow these tips: - Brush twice daily with fluoride toothpaste. - Floss regularly. - Eat a balanced diet and limit sugary snacks. - Visit your dentist for regular checkups and cleanings. If you suspect a cavity, see your dentist promptly. Treatments include fillings, crowns, and root canals, depending on the severity. Taking care of your teeth can prevent pain, infections, and tooth loss.###
