Snap-On Smile makes use of a custom-designed arch to fit directly over the teeth in order to conceal a diverse range of cosmetic concerns. Dental impressions of the patient are taken to make sure the arch is a perfect fit. Next, various shades and styles are reviewed to pick a virtually identical match to the patient's natural teeth. Next, the records will be sent to a proprietary lab where Snap-On Smile is fabricated in about 3 weeks. Once it is created, the arch is placed on the patient's teeth.
