Whitening Your Teeth

The food and beverages we consume in our everyday lives can all affect the color of our teeth over time. However, with new developments in dentistry, teeth whitening procedures can completely change the appearance of our teeth! Let’s take a closer look on what’s really happening with the color of our teeth:

Tooth stains can be both intrinsic (inside) and extrinsic (on the surface). Tooth whitening works best on the outside surface of your tooth (the enamel) where treatments can quickly remove staining. The thickness and texture of your enamel mainly determines the color of your teeth but smoking, coffee, red wine, and neglected oral health all result in intense discoloration. Your tooth’s dentine, the dense tissue under the enamel, affects your tooth’s shade as well. Over time, stains can develop on the pores of your enamel and the coating around it, known as the pellicle. 

Before teeth whitening can be performed, all cavities must be filled to prevent the whitening substance from entering inside the tooth. Sensitivity following tooth whitening can occur, especially for those with tooth decay or receding gums.

Vital and Non-Vital Whitening: 

Teeth are first cleaned and a rubber protectant is placed around the teeth before any whitening is performed. During vital whitening, a carbamide peroxide gel is placed on the tooth’s surface. A laser light is then used to active the whitening gel.

For whitening your teeth at home, we create a mouth guard by taking a dental impression of your teeth. The mouth guard is then filled with the carbamide peroxide gel and worn for a certain amount of time, as recommended by our dentists depending on your unique case.  

A non-vital whitening is needed to correct the color inside the tooth. A tooth may become discolored from the inside when a person has had a root canal procedure. During non-vital whitening, a special whitening substance is filled inside the tooth and topped with a filling. 


Depending on the severity of your discoloration, it may take multiple visits to our office to get that Hollywood smile. Make sure to contact to contact us if you feel gum or tooth sensitivity following treatment, though some discomfort is normal. Tooth whitening can last up until 12 months. However, if not properly maintained, the whitening can fade in a month’s time due to restaining.
