Tooth Sensitivity and Aftercare
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.
The VITA Shade Guide Explained
Colour is tracked on the VITA scale — A1 at the light end through to C4 at the dark. Untreated teeth usually fall around A2–B3 in Treharris patients, with whitening moving them several grades lighter.
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.
