Teeth Whitening: What Works, What’s Safe, and What It Costs
Between influencer strips, “miracle” powders and salon offers, whitening is the most misinformation-heavy corner of dentistry. Here’s the professional version: what actually whitens teeth, what’s marketing, and what’s risky.
Why teeth discolour in the first place
Two kinds of stains: surface stains from tea, coffee and tobacco sit on the enamel and respond to professional cleaning and polishing. Deeper discolouration lives inside the tooth structure and only responds to peroxide-based whitening done at proper concentrations — which is a dental procedure, not a cosmetic product.
In-clinic whitening vs everything else
Professional in-clinic whitening uses dentist-grade gel, gum protection and light/laser activation — shade improvement is visible in a single session. Dentist-made home trays get there more slowly but suit sensitive patients. Whitening toothpastes remove some surface stain only, and unsupervised high-strength products bought online are where we see burned gums and etched enamel.
Crowns, veneers and fillings do not whiten — if these are visible when you smile, your plan needs sequencing (whiten first, then match new restorations), which is exactly the sort of thing a cosmetic consultation sorts out.

Keeping the result
Whitening isn’t permanent — the same coffee that stained your teeth once will try again. Results typically hold 1–3 years, longer with sensible habits: rinse after staining drinks, don’t smoke, and keep up 6-monthly cleanings. Sensitivity after whitening is common for a day or two and settles; we tune gel strength for sensitive patients.
Patient FAQs
Is professional whitening safe for enamel?
Yes — done at dental-clinic concentrations with gum protection, peroxide whitening does not damage enamel. The risk comes from unsupervised high-strength products used at home.
How white will my teeth get?
Most patients gain several shades in one in-clinic session. Your starting shade and the cause of discolouration set the ceiling — we’ll show you a realistic target before starting.
Why won’t my crown whiten with my teeth?
Whitening gel only works on natural tooth structure. Crowns, veneers and fillings keep their manufactured shade — which is why whitening comes first, and restorations are matched after.
Does whitening cause permanent sensitivity?
No. Temporary sensitivity for 24–48 hours is common and settles on its own. Tell us if you’re already sensitive — we adjust the protocol.
