Professional whitening is costly. In addition, a 2015 Scientific World Journal study indicated that dental laser-whitening procedures may harm tooth pulp and increase sensitivity.
DIY whitening treatments are a good laser-free option. These are cheaper and easier to accomplish at home. Rinsing with coconut oil or periodically brushing with hydrogen peroxide or baking soda are typical ways (Medical News Today).
Some people cover their teeth with aluminum foil after using these whitening treatments to prolong their use. Foil, such wrapping aluminum foil over hair highlights, may help these chemicals set in. At-home teeth whitening may sound appealing, but doctors warn that it can cause discomfort, gum irritation, and enamel loss.
Seaglass Dental Care specialists recommend making a paste of water and baking soda to whiten teeth with aluminum foil. Some add salt, hydrogen peroxide, or toothpaste (B. Weiss).
They then paint the solution on aluminum foil or directly on the teeth with a toothbrush or finger. They finish by wrapping a foil strip over the front and rear teeth for 60 minutes.
Unfortunately, salt and baking soda can erode tooth enamel, especially if kept on teeth for long periods. Hydrogen peroxide can also irritate gums over time.
Additionally, mistakenly chewing on the foil might cause a minor electrical charge to irritate tooth nerves and cause pain. Patients with crowns or fillings are at danger.
