After braces are removed, most patients will need to wear a retainer all the time for the first six months, then only during sleep for many years.our orthodontist will want to see you about every month or so in order to make sure the braces are exerting steady pressure on the teeth. To create more tension and pressure on your teeth, the orthodontist will make adjustments in the wires, springs, or rubber bands of the braces.
How long will I have to wear the brace? It really depends on how much work there is to do and how far your teeth need to be moved. Fixed braces - usually take between 12 and 24 months, but could take longer if the problem is severe. Removable braces - usually take less time than a fixed brace. However, you might need to wear a removable brace before and after you have finished your treatment with a fixed brace. Your dental team or orthodontist will be able to give you advice about your brace and teeth. If you don't do what they say, the brace can take longer to work and the treatment may be unsuccessful.
