Question 1

How long do whitening results last?

Accepted Answer

Typically 1-2 years, depending on diet and smoking. Coffee, tea, red wine and tobacco gradually re-stain teeth. Home top-up trays make the result last much longer.

Question 2

Will whitening damage my enamel?

Accepted Answer

No — professional whitening gels at clinical concentrations do not weaken enamel when done correctly. Sensitivity for a day or two is the most common side-effect and settles on its own.

Question 3

Can whitening lighten crowns or veneers?

Accepted Answer

No. Whitening only works on natural tooth enamel. If you have crowns or veneers in the smile zone, the natural teeth will lighten and the artificial ones will need to be replaced to match.

Question 4

Are at-home whitening kits as good?

Accepted Answer

They are weaker and work slower — but they are perfectly safe when supervised. We often combine an in-clinic boost with at-home maintenance trays for the best long-term result.
