Invisalign is an alternative technique for straightening teeth using a custom made series of aligners created just for you. The aligner trays are made of smooth, comfortable and virtually invisible plastic that you wear over your teeth. Wearing the aligners gradually and gently moves your teeth into place, based on the exact movements designed by your dentist. There are no metal brackets or wires to tighten. You will put in a new set of aligners about every two weeks until your treatment is complete and you have achieved the smile you always wanted. The best part of the process is that most people won't even know you are straightening your teeth! Invisalign is an excellent approach for many patients, but must be evaluated by your dentist to be sure it will work for you.
