Professional teeth whitening is one of the most popular cosmetic dental treatments there is. Patients across Trefin choose it because the shade lift is calibrated to their teeth and sensitivity. Results can appear in a single in-chair session or build gradually over two to three weeks at home.
Sensitivity, Aftercare and Keeping Results
Transient sensitivity is normal and short-lived. Pre-treating with a sensitivity toothpaste, and avoiding very hot or cold drinks for a day or two afterwards, keeps it manageable for most people.
For 48 hours afterwards, avoid intensely pigmented foods and drinks — coffee, tea, red wine, berries, tomato sauces — while the enamel is temporarily more porous. Results typically last 12–24 months before a short top-up restores the shade.
How Tooth Colour Is Measured
Dental professionals in Trefin use the VITA classical shade guide to record tooth colour, running from A1 (lightest) to C4 (darkest). Most natural teeth sit between A2 and B3, and professional whitening typically lifts 4–8 grades.
Not all teeth respond equally. Intrinsic staining from tetracycline or fluorosis whitens poorly, yellow tones respond best, and grey tones least. Crowns, veneers and fillings don't change colour at all, which can create mismatches to plan around.

Is dentist whitening better than at-home kits?
For a real result, yes — dentists can legally use stronger peroxide concentrations than over-the-counter kits, and they customise to your shade and sensitivity, plus catch any underlying issue before it complicates whitening.
Will whitening affect my crowns or veneers?
No — whitening gel does not change the colour of crowns, veneers, bonding or composite fillings. If your restorations are placed on visible front teeth, whitening the surrounding natural teeth may create a colour mismatch. Discuss this with your dentist before treatment so a plan can be made.
