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.
For the retainer to be effective you will have to wear it permanently initially. On your dentistâs recommendations, the retainers can be worn only at nights. The actual number of months that the retainer needs to be worn will vary from person to person and how much your teeth need to be aligned in a straight line.he retainers are the ones that are going to keep your teeth just the way you wanted them and that is long after the braces are off. Although not many people are aware of this, they are considered to be the most important aspect of the treatment in teeth braces.
