Stains on teeth can be classified in one of two ways: external or internal. External stains appear on the outer surface of your teeth; internal stains live deep in your enamel and within your dentin (the layer of your tooth underneath your enamel).
Whitening toothpastes may be able to remove some of the external stains on your teeth, but only teeth whitening agents can remove the internal stains that cause your teeth to look discolored. The whitening gel uses an oxidizing agent that penetrates your enamel to neutralize the stains that are present in the next layer of your tooth.
At your first appointment, impressions will be taken of your teeth, and from those impressions, custom made whitening trays will be made. The custom made trays and the strength of the whitening gel is the difference between using over the counter products and the products available to you here in our office. At the second appointment we’ll deliver your custom trays and teach you how to use them. We’ll also document your existing shade with a photograph of your smile and we’ll use our shade guide to choose your pre-whitening shade.
