In-office teeth whitening is a great way to safely enhance your smile. Dentists suggest getting whitening treatment about once a year to keep your teeth looking aesthetically pleasing. However, bleaching your teeth too often can cause serious oral health issues, such as enamel erosion. Excessive teeth whitening can lead to the death of tooth enamel, which is the outermost layer of the teeth, and can also expose the inner parts of the tooth, including the nerves and pulp.
This can cause infections and damage that sometimes result in tooth decay. It's safe to use teeth whitening trays that are four hours apart from each other. But if you're looking for a more cost-effective way to whiten your teeth, visiting a hygienist is a great option. Regular visits to the hygienist are especially beneficial for keeping your teeth white (both before and after teeth whitening treatments).When it comes to over-the-counter products, there is little clinical evidence to suggest that any of these can have long-lasting whitening effects on teeth.
It's milder for your teeth to use a slightly less strong tooth whitener, but with more applications to achieve the same level of whiteness than if stronger whitening gels were used. Generally speaking, it's good practice to return to the dentist for teeth whitening services about once every three months. This means that even if your teeth are heavily discolored, they should look much brighter than average after a properly administered teeth whitening treatment. Home teeth whitening treatments, such as trays and strips, work very well when there are only a few shades of stain left to remove. If you want to know how often you can whiten your teeth with strips, you might need something stronger. That said, there's little evidence to suggest that any of them can effectively brighten your smile.
