The primary method of abscess prevention is engaging in dental hygiene practices that can prevent tooth decay (a common cause of dental abscesses). These practices include:

• Brushing teeth. Removes plaque that can cause tooth decay. Teeth should be brushed upon awakening, before sleep and after every meal.
  
  
• Daily flossing. Removes plaque and food particles that become lodged between teeth. Teeth should be flossed every day.
  
  
• Regular dental examinations and cleanings. This removes the buildup of tartar on the teeth and helps to identify problems early, while they are easy to treat and before they can become abscesses.
  
  
• Sugarless gum. Chewing sugarless gum may help rid the mouth of food particles and bacteria when people are unable to brush their teeth (e.g., after meals when away from home).
  
  
• Healthy diet. A well-balanced diet can help people maintain their immune systems and avoid infections. Patients should specifically avoid sugary foods and beverages that can lead to tooth decay.
  
  
• Treat dry mouth. A lack of saliva in the mouth (which helps to keep the area clear of food particles and bacteria) can increase the risk of tooth decay. Drinking plenty of water, chewing sugarless gum or sucking on sugarless candy can help promote saliva production. Medication may be needed to treat severe cases of dry mouth.
  
  
• Avoid tobacco. Smoking or chewing tobacco can increase the risk of gum disease and potentially lead to infections and dental abscesses.

Some patients may receive antibiotics prior to any dental treatment to prevent the risk of infection. This includes patients with immune system deficiencies, other medical conditions (e.g., heart valve problems) or on certain medications.
