You probably know quite a few people who have whitened their teeth as it’s an extremely popular cosmetic dentistry treatment. However, if you ask those who used an over-the-counter whitening kit about their experience, you’ll probably find the results were less than stellar or that they encountered some unpleasant side-effects during the entire process. If you question people who have had a professional tooth whitening treatment, you’ll find the answers are very different. Because it is easy to buy over-the-counter whitening kits, some people assume that teeth whitening isn’t really a dental treatment, but the very opposite is true. Misusing over-the-counter kits or whitening an unhealthy mouth could cause significant damage to your teeth and gums, so why take the chance? Your teeth are incredibly precious and are designed to last the life but can only do so if you treat them properly.
