Why do you need to wear retainers after correction?

After the correction is completed, the teeth become neat and beautiful by removing the appliance, but this is only half of the Long March. Next, you must put on the retainer. Because the teeth are still unstable in the new position at this time, it takes a year and a half to keep the new tooth position with the help of retainers and wait for alveolar bone reconstruction. There are two kinds of retainers: movable and fixed. Fixed retainers, also known as permanent retainers, are usually used for adult patients. Generally, you will feel some pain and chewing weakness within 3-6 days after wearing the fixed appliance and each follow-up visit. You can eat soft food these days. Generally, the pain will be gradually relieved until it disappears. Many adults want to straighten their teeth very much, but they are worried about "steel mouth and iron teeth" after wearing orthodontic appliances. For aesthetic reasons, people invented transparent brackets and lingual appliances. Transparent brackets are similar in color to teeth, so they are not obvious. The lingual appliance sticks the bracket to the inside of the tooth close to the tongue, so it can't be seen from the outside.
