LOOKING FOR

A Dazzling Smile

TEETH WHITENING

Teeth whitening is a type of aesthetic procedure that lightens or whitens the shade of the tooth thus enhancing one’s smile. It involves using peroxide-based whitening agents to lighten teeth. Typically, it’s ideal for people who have healthy and natural teeth. Teeth whitening don’t work if you’ve gum disease or restorative teeth, including dentures, fillings, veneers, and crowns-a reason you should consult with your dentist before embarking on this procedure.

WHY YOU MAY NEED TEETH WHITENING

Since the tooth is made up of porous layers, plaque and stain easily accumulate around it. Discoloration can be due to foods and drinks you consume, dental restorations, antibiotics (in kids below 8 years), and tobacco use. Whitening helps remove these stains and brighten your smile.

Teeth Whitening FAQ

Click a question to expand the answer.

Is professional teeth whitening safe?

Yes—when supervised by a dental team and used on healthy teeth and gums. We assess sensitivity risk, gum health, and existing dental work before recommending the safest option.

How long do whitening results last?

It depends on your habits and tooth shade, but many patients maintain results for months to a few years. Coffee, tea, red wine, smoking, and natural aging can shorten longevity—touch-ups can help maintain brightness.

Will whitening work on crowns, veneers, or fillings?

No—whitening changes the colour of natural tooth structure, not restorations. If you have dental work on visible teeth, we’ll plan whitening so your smile stays even and natural-looking.

What causes tooth sensitivity during whitening?

Sensitivity can happen when whitening temporarily increases fluid movement in the tooth. We can adjust gel strength, timing, and add desensitizing options to improve comfort.

In-office vs take-home trays—what’s better?

In-office whitening is faster. Take-home trays are more gradual and often easier for sensitive teeth. The best choice depends on your timeline, shade goals, and comfort.
