Whitening, also called bleaching, may be carried out in the dental office or the dentist may instruct the patient on how to do the bleaching at home. There is also a wide variety of products for sale in stores. Not all products are the same and not all give you the same results.
Whitening toothpastes with abrasive ingredients are really not bleaching products at all, but work on surface stain only. These products are sold in many stores.
Some whitening toothpastes do contain a chemical ingredient (or “bleach”) that causes a chemical reaction to lighten teeth. Generally, they have the lowest amount of “bleach.” They may not whiten as well as stronger products, but they have less chance of side effects. These pastes are brushed onto teeth and rinsed off, like regular toothpaste.
Bleaching kits sold in stores stay on your teeth longer than toothpaste and contain stronger bleach.” These store-bought products do not come with the added safety of having your dentist monitor any side effects. They also come with a one-size-fits-all tray that holds the “bleach” and is more likely to leak the chemical into your mouth.
Dentists may use products with stronger “bleach”, but they give patients careful instructions to follow. In addition, if a tray is needed to apply the “bleach”, dentists supply custom-made trays. Because products used by dentists are strong, they tend to produce the best results.
Patients should be aware that the long-term use of whitening or bleaching products may cause temporary tooth sensitivity. Please consult with your dentist before using a whitening or bleaching product.
