Clear retainers are almost invisible trays that gently move and straighten your teeth, without anyone really noticing (seriously!). We use Invisalign to deliver these, they were the first to develop this tech. For best results, you’ll need to wear them minimum 22 hours a day, just taking them out for meals. Clear teeth aligners help to correct gaps, crowding, overbites, underbites or overlapping. How good is that?
