What's the difference between in-clinic whitening and at-home kits?
In-clinic whitening uses a higher-strength gel activated under controlled conditions, giving faster, more dramatic results in a single visit. At-home kits use a lower-strength gel worn over one to two weeks — a slower but still effective option.
How much whiter will my teeth actually get?
Results vary by starting shade and the cause of discoloration, but most patients see a noticeable improvement of several shades. Whitening works best on surface staining rather than deep or medication-related discoloration.
Is teeth whitening safe for enamel?
When done properly under professional supervision, whitening is considered safe and doesn't damage healthy enamel. Some temporary sensitivity during or after treatment is common and usually fades within a day or two.
How long do whitening results last?
Typically 6 months to 2 years, depending on your diet (coffee, tea, red wine and smoking all speed up staining) and oral hygiene. Occasional touch-ups help maintain results.
Will whitening work on crowns, veneers, or fillings?
No — whitening gel only works on natural tooth enamel, not on existing restorations. If you have visible crowns or fillings, mention this beforehand so results look even.
Who shouldn't get teeth whitening?
Pregnant or breastfeeding women, people with untreated cavities or gum disease, and those with very sensitive teeth are usually advised to wait or take extra precautions — a quick check-up first avoids problems.
How long does an in-clinic whitening session take?
A typical in-clinic whitening session takes about 60–90 minutes.
