Are Tooth Whiteners Safe?
In 2019 alone, more than 38 million people used teeth whiteners, according to Statistica. And the year hadn’t even ended when the data was compiled. That number is projected to hold steady over the next few years and puts into numbers what we already know: a lot of people use teeth whiteners to get whiter, brighter teeth. But are they safe?
Teeth Whiteners Can Cause Damage
Studies have shown that overuse of certain teeth whitening products, more specifically those that contain hydrogen peroxide, can damage teeth. You can liken it to the effects of hair lightening products, which also rely on hydrogen peroxide. If you use these products too often, or leave them on for too long, you get a breakdown of the underlying tissues. In teeth, this protein-based tissue is called dentin.
Similar damage may occur to the enamel, or outer layer of the tooth, as well. Cleveland Clinic says that some research has shown that whitening products soften the enamel, resulting in roughed-up appearance.
But They Are Safe If Used Properly
Keep in mind that all of these studies point to damage caused by the overuse of these products. What’s more, the teeth used in the experiments were not performed on living teeth. Rather, they were performed on loose teeth in a lab.
The ADA has also said that teeth whitening products are safe and effective if used properly. The organization has even developed a seal of approval, which is prominently displayed on the packaging of ADA-approved teeth whitening products.
Here’s What to Do to Protect Teeth
The key to preventing damage is to use these products as specified. Always look for the ADA seal and follow all instructions. The instructions will state how long to leave the product on and how often to use it. Respect the instructions. Do not use the product outside of them, even if different results are desired.
These are the primary complications to watch out for and which should cause a user to immediately stop using teeth whitening products and speak to a dentist:
- Burning gums
- Bleeding gums
- Extreme sensitivity
- Translucent teeth
- Thinning teeth
- Tooth pain
Overall, teeth whiteners are fairly safe if used properly. However, they can cause issues with overuse. To avoid any issues, always use products approved by the ADA and follow all instructions. When in doubt, ask a dentist.
