People often notice improvement after their first treatment. The number of treatments needed varies depending on your teeth. Usually 1 to 10 treatments are sufficient to achieve a whiter smile. Factors that play a role in this are how white you want your teeth and how strong the discoloration was before the treatment started.

A whitening treatment from Smyle works in the same way as that of a dentist. The whitening gel effectively removes discolorations, making your teeth whiter and more beautiful, without causing damage to or changes to the enamel. The bleaching process focuses on removing discolored particles, both on and partially within the enamel pockets, without affecting the enamel itself. Our products have a pH value equal to the natural pH value of the oral cavity, which is approximately 7. For comparison, soft drinks have a pH value of 2.9.

Our products do not contain substances harmful to teeth and gums (and the planet).

It is not possible to whiten teeth with Smyle whitening gel if you have artificial teeth made of, for example, composite plastic/porcelain, fillings or dental jewelry. These parts are not bleached because our products are designed to bleach enamel.

The effect of teeth whitening is not permanent. After treatment, the teeth will discolor again over time due to consuming colored foods and drinks, aging and possibly smoking or snacking. The results remain visible for 6-12 weeks, after which you can easily repeat the treatment to maintain the desired effect (recommended every 3 months).

We recommend that you whiten your teeth once a day during the treatment. For an accelerated result, some people choose to whiten their teeth in the morning and evening. If you are satisfied with the whiteness, stop the treatment. You will notice a gradual color difference, so you do not run the risk of unnaturally white teeth.

Avoid consuming colored foods and drinks for up to 4 hours after a treatment to achieve optimal results.

Our whitening products contain up to 7 active ingredients that together clean and brighten your teeth. For the gel to work effectively, it must first penetrate the teeth. This is essential for optimal results, and Smyle's unique gel is quickly absorbed by enamel and dentin. The whitening gel works with a natural enzyme present in saliva, releasing oxygen that whitens both enamel and dentin. This process is similar to the products used and sold by dentists. The specific contents of each gel are listed below the ingredients list on each product.
