How Teeth Whitening Really Works

Why Teeth Turn Yellow

Before we go over the process of teeth-whitening, let's take a moment to understand the causes of discoloration in teeth.

Each tooth is made up of an inner dentin layer and a hard outer enamel layer, which essentially protects the teeth. Things like food, cigarette smoke, coffee, and etc. naturally create an additional layer on top of the enamel later. This extra layer on top is the biggest cause to the discoloration of our teeth.

Teeth Whitening at Southridge Dental

Nowadays anyone can whiten their teeth with the numerous teeth whitening products out on the market, but it’s very important to consider a few things before going out of your way to do that. Before whitening any of your teeth, it is very important - not only for your results, but also for your health - to have your teeth properly cleaned, have any cavities filled, and make sure your gums are in healthy shape. So in order to achieve the absolute best result and experience, having Dr. Bhatha and the Southridge Dental team makes the most sense. It’s also very common to be treated in-office or at-home with one of our kits right after you’ve received your cleaning..

Over-the-counter Teeth Whitening

Over-the-counter tooth whitening involves the use of carbamide or hydrogen peroxide. Since it isn't always mentioned in the product instructions, make sure to get your teeth professionally cleaned, have all your cavities filled, and make sure your gums are healthy before using any teeth whitening 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.

Is Tooth Whitening Safe?

Majority of the case studies on teeth whitening show that the method is both safe and effective. Whitening gels that contain 10 percent carbamide peroxide (equivalent to 3.6 percent hydrogen peroxide) have shown to cause no damage to the enamel layer of the tooth. Higher concentrations of carbamide and hydrogen peroxide available from the dentist can potentially weaken the enamel, but most of these formulas also contain fluoride, which is designed to prevent this overall.

If tooth sensitivity or gum irritation occur, it is best to use the whitening product less and reduce the amount of time spent whitening. Prescription fluoride can be used to treat the sensitivity sometimes associated with tooth whitening. Irritation of the gums can occur from either the in-office, at-home or over-the-counter tooth whitening systems. Gum irritation is usually mild and reversible, but can be treated with over-the-counter products such as Orajel.

The best time to have your teeth whitened is right after your cleaning, so the next time you see Dr. Bhatha or the Southridge Dental team be sure to request a whitening! We always encourage new patients to contact us at (604) 575-1555 to schedule a cleaning and teeth whitening with us
