Tired of cheap whitening teeth tray imitations? Then try our professional custom whitening teeth trays! They are made in J&J Dental Lab. After you mail your impressions to our lab, we pour up stone models and then use a special vacuum forming machine to cast an exact replica of your unique dental arch - one tray for the top and one for the bottom. We then finish the trays by scalloping (trimming) around each tooth so you can effectively keep the whitening gel away from your gums and precisely on your tooth.
