What Changes the Price
- How stained the teeth are. Tea and paan stains are surface stains and come off fast. Tetracycline or fluorosis marks sit inside the enamel and may need two sessions, or veneers instead.
- Cleaning first. Whitening gel cannot work through tartar. If it has been more than a year since a scaling, a cleaning is added before whitening.
- Sensitivity management. Desensitising gel before and after adds to the comfort of the procedure.
- Existing crowns, fillings or veneers. They do not whiten. If a front tooth has a crown, the plan changes.
Is It Painful? Does It Damage Enamel?
No damage, some sensitivity. Roughly a third of patients feel cold sensitivity for 24–48 hours after an in-office session. It goes away. Enamel is not thinned by professional peroxide gel at the concentrations dentists use.
How Long Does It Take?
One visit of about an hour for chairside.
How Long Does It Last?
12 to 24 months for most people. Coffee, tea, red wine, smoking and paan pull it back faster. A yearly single-cycle top-up keeps it there.

Frequently Asked Questions
Kolkata mein teeth whitening ka kharcha kitna hai?
₹7,000 se ₹15,000 tak (in-chair laser session). In-office ek sitting mein ho jaata hai.
Is laser whitening better than LED whitening?
Same gel, different light. The light speeds up the gel; it does not whiten by itself.
Can I whiten with braces or aligners on?
Not with fixed braces (you get patches). With clear aligners, yes — the aligner tray doubles as the whitening tray.
Will whitening fix yellow teeth from tetracycline?
Partly. Grey-blue banding usually needs veneers.
Does whitening work on caps or fillings?
No. Natural enamel only. New restorations are matched to the whitened shade afterward.
How soon can I drink tea after whitening?
48 hours of a “white diet”: no tea, coffee, turmeric, red wine, paan. After that, normal.
