Keeping Your Teeth Straight After Orthodontic Treatment
It is important to remember that your teeth can move throughout life whether or not you have had braces. At the end of treatment you will be provided with retainers which are designed to keep your teeth straight. My usual advice is to wear retainers full time for four to six months following completion of treatment; then retainers are worn at night time for a further four to six months. Retainer wear is recommended for one to two nights a week for an indefinite period of time. Clean retainer braces with soap and water or special cleaning tablets; toothpaste can damage clear retainers.
Retainers should be worn for as long as you wish to keep your teeth straight.
The British Orthodontic Society has produced a YouTube Video about the importance of wearing retainers.
