Invisalign®
Invisalign® is a brand of clear aligner treatment: a series of removable, nearly invisible trays that move teeth gradually. Ask our office about aligner treatment and whether it suits your case.

How it works
You wear each set of trays for about twenty-two hours a day and move to the next set every week or two. The trays come out for meals and for brushing.
Is it right for you?
Aligners suit many cases of crowding and spacing. We look at your bite first and tell you honestly whether aligners or braces would do the better job.
