Most people have some discomfort after their braces are first put on or when adjusted during treatment. After the braces are on, teeth may become sore and may be tender to biting pressures for a few days. The orthodontist may prescribe some pain relievers if necessary. The lips, cheeks and tongue may also become irritated for a few weeks as they toughen and become accustomed to the surface of the braces. Orthodontic wax may be used to cover the braces to reduce the irritation. Overall, orthodontic discomfort is short-lived and easily managed.
