Because over-the-counter whitening solutions aren’t custom-created for your individual mouth, they can be difficult to apply and are not very precise. On the other hand, our professional in-office whitening gel is applied carefully and accurately to each tooth, and our take-home kits are custom molded to fit your teeth. Over-the-counter whiteners also aren’t as effective. They can whiten your teeth up to three shades, whereas professional whitening can brighten your smile by up to 10 shades.
