A brightening toothbrush is a mouth wash that has a high concentration of the ingredient salicylic acid. It's also commonly known as a toothpaste. Some dentists have started prescribing topical salicylic acid for people with light teeth. You can buy it at many pharmacies. Salicylic acid can be very effective at getting rid of tartar (the film forming substance that helps protect the teeth when they're young). Salicylic acid also works to keep your teeth and gums in good condition as well. Salicylic acid is also very good for keeping the enamel on your teeth healthy. The more you use salicylic acid, the more powerful it becomes. It's also easier to use. Some people find that salicylic acid helps their gums and teeth. Salicylic acid is most often used as a creme or as an oral scrub. The mouth is the most sensitive part of the body to the acid and the acid gets into the tissue there. It can get in your gums and into your teeth, and can be a problem if you don't get it out. If you want to use salicylic acid on the teeth, you'll need a dental hygienist to check your gums. You should get a regular dental check every two weeks to make sure the acid is getting out. There is no way to be 100% sure.
