Tooth discoloration can cause teeth to turn yellow, darken, or develop white or dark spots. Whitening toothpaste can help restore the natural whiteness of your teeth, but it's important to use it correctly. When used twice a day, whitening toothpaste can take two to six weeks to make teeth appear whiter. For an immediate effect, look for toothpastes that contain blue covarine.
It's best to consult your dentist before attempting any whitening procedure. They know exactly how much whitening cream to apply and how long you should leave it on without damaging your teeth or gums. If you don't follow the instructions carefully, you could end up with severely damaged teeth that require expensive and painful procedures like porcelain veneers or composite caps. White teeth are often associated with health and beauty, but there's nothing particularly harmful about teeth with some stains.
There are some reliable ways to brighten your smile at home, but it's important to be aware of the risks of whitening attempts by amateurs.
