This is a voluntary program that requires a lot of expense and time so most manufacturers of teeth whitening products may choose to skip the procedure all together. However, you must realize that a teeth whitening product without the ADA’s Seal of Acceptance might also be safe to use. You can be assured, however, that products that do carry the seal are certified to be safe.

Teeth whitening products that are dispensed through dentist’s offices are usually ADA compliant. Several whitening toothpastes that are freely available over-the-counter
ADA compliant but other over-the-counter teeth whitening products are not certified by the ADA. To differentiate between the two types, check online websites and ask your local chemist for advice. Teeth whitening kits are not considered to be drugs and therefore they are not monitored by the ADA. Consider the following factors when selecting a teeth whitening kit.

- Select a teeth whitening kit that allows you to mold the mouthpiece somewhat. These are more comfortable than others

- 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.
