You can be assured, however, that products that do carry the seal are certified to be safe.

- Ask the opinion of others who have already tried the teeth whitening kit you are planning to buy

- If you see that the color of your gums starts changing or if you detect an increase in teeth sensitivity, stop using the kit immediately. Then, consult a professional dentist.
