Professional Teeth Whitening

Why Teeth Change Colour

Staining can come from coffee, tea, red wine, tobacco, some foods and normal ageing. Some changes come from inside the tooth, such as after an injury or from certain medicines.

Outer stains often respond better to whitening than deeper changes inside the tooth.

In-Office and Take-Home Whitening

In-office whitening uses a stronger product with the dentist watching the process. Take-home whitening uses custom trays and a milder gel you wear at home over several days.

Both methods use professional-grade materials. The right choice depends on your goals, comfort and daily routine.

Who May Not Be a Good Candidate

Whitening is not for everyone. It is often delayed when there is untreated decay, active gum disease, cracked teeth or sensitive roots. Crowns, veneers and fillings do not change colour with whitening.

Sensitivity After Whitening

Some patients feel short-term tooth or gum sensitivity. This usually settles within a few days. Using a soft brush and a sensitivity toothpaste can help.

Care After Whitening

• Limit staining drinks in the first day or two.
• Brush twice daily and floss to reduce new build-up.
• Keep regular cleanings and exams to check on the shade.

Alternatives for Deeper Staining

When whitening cannot reach a stain, options such as bonding, veneers or other cosmetic care may be discussed.

Cost Factors

Cost depends on the method, the number of visits needed and any care required before whitening starts.
