Invisalign is an increasingly popular choice for straightening teeth and is suitable for older teenagers and adults. The system consists of clear, removable plastic aligners that fit tightly over the teeth, gradually moving them into pre-determined positions. Each set of aligners must be worn for 22 hours each day and they are generally only removed for eating and drinking and for brushing and flossing.
Treatment is very discreet as the aligners are nearly invisible and it is effective for most common orthodontic problems. Invisalign can be ideal for adults who would prefer not to wear more visible fixed braces but who would love to have a straighter smile.
