Dentist-led whitening is a safe, effective way to lighten tooth shade by several grades. In Johnston it is a common request, and results go well beyond what a supermarket kit can manage. Some patients whiten in one appointment; others prefer the slower, gentler take-home route.
Understanding Tooth Shade — The VITA Scale
Dental professionals in Johnston 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.
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.
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.
