Whitening is one of the most common cosmetic treatments, and when done professionally it is also one of the safest. Understanding how it works takes the worry out of the process.
How Whitening Actually Works
Professional whitening gels use peroxide to break up the stain molecules that build up inside enamel over years of coffee, tea, and food. The structure of the tooth is not damaged; the discolouration is simply lifted.
Because we supervise the concentration and protect your gums, professional whitening is gentler on your mouth than guessing with over‑the‑counter products. That control is the main reason it stays safe.
Why Sensitivity Happens
Some people feel brief sensitivity during or after whitening, usually a fleeting zing with cold or air. This happens because the gel temporarily opens tiny channels in the enamel, and it typically settles within a day or two.
Sensitivity is temporary and does not mean harm is being done. Using a desensitizing toothpaste beforehand and spacing out sessions both reduce it considerably.
Keeping It Comfortable At Cambie
We start by checking for cavities, gum issues, or exposed roots, since treating those first prevents discomfort. Whitening a healthy mouth is far more pleasant.
We also tailor the strength and timing to your teeth rather than using a one‑size approach. If you have had sensitivity before, tell us, and we will adjust the plan for you.
