Professional whitening uses a controlled concentration of hydrogen or carbamide peroxide to break down the stain molecules held inside the enamel and dentine. It is a chemical process, not an abrasive one, which is exactly why the charcoal and baking soda routines circulating online do more harm than good. Those work by scrubbing away the surface, and enamel does not grow back.
Before whitening, the teeth need a scaling and polish. Bleaching over a layer of plaque and calculus gives a patchy result and wastes the appointment. Existing crowns, veneers and composite fillings do not change colour with bleaching, so if you have work on your front teeth, the sequence matters: whiten first, then match the new restorations to the lighter shade.
Not all discolouration responds to bleaching. Tetracycline staining, fluorosis and single dark non-vital teeth need different treatment. We will tell you honestly which category you fall into at the shade assessment rather than sell you a session that will not work.
You probably need this if…
- Teeth have yellowed gradually with age
- Staining from tea, coffee, tobacco, paan or red wine
- You have an event coming up, such as a wedding, shoot or interview
- One tooth is darker than the rest after an old injury or root canal
- Teeth look dull even immediately after brushing
Recognising two or more of these does not confirm a diagnosis. It means an examination is worth booking before the problem gets more expensive.
How the treatment works
- 01 Shade assessment
Your current shade is recorded against a standard guide and photographed, so the change is measurable rather than a matter of opinion.
- 02 Scaling and polishing
Done first. Bleaching over plaque gives an uneven result.
- 03 Gum isolation
A protective barrier is placed over the gums before the gel goes on. This is what prevents chemical burns.
- 04 Bleaching
Three 15-minute cycles of professional-grade gel, activated with light. Total chair time around 60–75 minutes.
- 05 Aftercare
A white diet for 48 hours while the enamel pores re-seal, plus a desensitising application if needed.
