In order to ensure good orthodontic results, patients wearing retainers should pay attention to regular follow-ups, continuous wearing within six months, and paying attention to a reasonable diet. 1. Initial discomfort, such as pressure and pain, should be followed up in time for appropriate adjustment to ensure the best orthodontic results. 2. The retainer should be worn every day and night for six months, and can be temporarily removed during meals and cleaned when brushing teeth. As the retainers are mostly plastic products, do not use hot water when cleaning. 3. Pay attention to the reasonable diet during the wearing period, do not eat hard food, so as not to affect the corrective effect. It is recommended that patients wearing retainers pay attention to the above points, and regular follow-up, if there is any discomfort in time to consult a professional dentist to take professional measures.
