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.
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.
Understanding Tooth Shade — The VITA Scale
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 Merthyr patients, with whitening moving them several grades lighter.
Response depends on the cause of the staining — surface and yellow discolouration whiten well, developmental and grey staining resist it, and any crowns or composite won't shift, so mismatches are worth discussing first.
