Orthodontic relapse refers to the tendency of teeth to shift back to their original position after orthodontic treatment has been completed. This can occur in both adolescents and adults, but in the context of adult orthodontic treatment, there are several situations that may contribute to relapse.

• Inadequate Retainer Wear:

  • Failure to consistently wear retainers as prescribed by the orthodontist is a common cause of relapse. Retainers are crucial for maintaining the new tooth positions achieved during orthodontic treatment.

• Changes in Soft Tissues:

  • The soft tissues surrounding the teeth (gums, lips, and cheeks) can adapt and change over time. If these tissues put pressure on the teeth, it may contribute to relapse.

• Natural Aging Process:

  • As individuals age, changes occur in the facial structure and the position of teeth may shift slightly. This can be a natural part of the aging process.

• Genetic Factors:

  • Genetic factors can influence the stability of orthodontic results. Some individuals may be more prone to relapse due to their genetic predisposition.

• Poor Oral Habits:

  • Certain oral habits, such as thumb-sucking or tongue thrusting, nail biting,  can exert forces on the teeth and contribute to relapse if not addressed.

• Missing Teeth:

  • Gaps created by missing teeth can cause adjacent teeth to drift into the open space, leading to relapse. This is why replacing missing teeth is important for maintaining orthodontic results.

• Periodontal Changes:

  • Changes in the supporting structures of the teeth, such as gum and bone, can impact tooth stability. Periodontal issues may contribute to relapse if not addressed.

To minimize the risk of relapse, it’s crucial for adults who have completed orthodontic treatment to adhere to the recommended retainer wear schedule and follow any post-treatment instructions provided by their orthodontist. Regular check-ups with the orthodontist can help monitor the stability of the results and address any emerging issues promptly. If relapse does occur, additional orthodontic treatment may be needed to correct the changes in tooth alignment.
