Professional teeth whitening is one of the most popular cosmetic dental treatments there is. In Knockhall it is a common request, and results go well beyond what a supermarket kit can manage. Results can appear in a single in-chair session or build gradually over two to three weeks at home.
Managing Sensitivity After Whitening
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.
A brief 'white diet' — skipping strongly coloured food and drink for two days — protects the fresh result. Long-term, good hygiene and an occasional top-up every 12–18 months keep teeth bright.
How Tooth Colour Is Measured
The VITA guide gives whitening an objective before-and-after in Knockhall: most teeth start near A2–B3, and a course commonly achieves a 4–8 shade improvement.
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.
