Here’s What Really Happens When You Whiten Your Teeth

Friday, August 26, 2016 | 7:15 pm

Have you ever wanted a white, attention-grabbing, perfect “Hollywood” smile? Of course you did! Tooth whitening is the most common cosmetic service provided by dentists, and there are also a growing number of over-the-counter tooth whitening products to choose from.

Each of your teeth is made up of an inner dentin layer and a hard outer enamel layer, which protects the teeth. When you put stuff in your mouth, such as food, cigarette smoke, coffee, etc. Another layer gradually forms on top of the enamel layer. Basically, the foreign material accumulates to form a pellicle film over the enamel layer.

Before the tooth whitening treatment, most dentists clean the teeth, fill any cavities, and make sure the patient’s gums are healthy. Dentist-supervised tooth whitening involves the controlled use of carbamide or hydrogen peroxide, tailored to a particular patient. Dentists may administer in-office treatments or at-home treatments. Carte Blanche offers a lot of affordable, safe options for your teeth – even if they are sensitive.

If you don’t want to go to professional, over-the-counter tooth whitening also involves the use of carbamide or hydrogen peroxide. It isn’t always mentioned in the product instructions, but it’s a good idea to get your teeth professionally cleaned, have all your cavities filled, and make sure your gums are healthy before using these products.

The most popular products use either carbamide or hydrogen peroxide gels or hydrogen peroxide containing polyethylene strips. Most of these products are relatively easy to use, and independent research has shown that they are effective.

Most studies confirm that tooth whitening is safe and effective. Whitening gels that contain 10 percent carbamide peroxide (equivalent to 3.6 percent hydrogen peroxide) have not been shown to cause any damage to the enamel of the tooth. Higher concentrations of carbamide and hydrogen peroxide available from the dentist may weaken the enamel, but most of these formulas also contain fluoride offsetting this potential side-effect.
