Risk factors

These factors may increase your risk of a tooth abscess:

• Poor dental hygiene. Not taking proper care of your teeth and gums — such as not brushing your teeth twice a day and not flossing — can increase your risk of tooth decay, gum disease, tooth abscess, and other dental and mouth complications.
• A diet high in sugar. Frequently eating and drinking foods rich in sugar, such as sweets and sodas, can contribute to dental cavities and turn into a tooth abscess.
• Dry mouth. Having a dry mouth can increase your risk of tooth decay. Dry mouth is often due to the side effect of certain medications or aging issues.
