ClearÂ Aligners are an alternative to traditional braces and are designed to help guide teeth into their proper position. Â Similar to braces, clear aligners use a gradual force to control tooth movement, but without metal wires or brackets. Â The aligners are made of a strong plastic material and are fabricated to fit each person's mouth. If a series of aligners are made, each aligner moves the teeth a little bit more into place until the desired movement is completed.
Aligners are worn for at least 20 hours a day to reach the desired maximum effectiveness. Â Each aligner is worn for three weeks before changing to the next one. Â The length of treatment with aligners depends upon the severity of each case. Â Typically, aligner treatment can be as short as three weeks or as long as six months. Â Still, a much shorter treatment than traditional braces.
