It is very important to keep your teeth and gums healthy during orthodontic treatment. Poor oral hygiene may result in swollen and bleeding gum tissue. Gentle and thorough brushing, rinsing with warm salt water and mouthwash will help return the gums to a healthy state. Also use dental floss to check the swollen area to see if food debris may be trapped under a band or bracket. Orthodontic tooth movement may also cause swollen gums. If the steps above do not help the situation, please call Dr. Boyd.
