Whitening supplied by a registered dental professional uses far stronger gel than anything sold over the counter. It's a mainstay of cosmetic dentistry in Welwyn, delivered under proper clinical supervision. Results can appear in a single in-chair session or build gradually over two to three weeks at home. People from Danesbury, Digswell Park and Ayot Saint Peter regularly visit orthodontists in Welwyn.
Sensitivity, Aftercare and Keeping Results
Some patients feel sensitivity during whitening, particularly in-chair. Using a potassium-nitrate or stannous-fluoride toothpaste for one to two weeks before treatment cuts this significantly, and a desensitising gel can be used between sessions.
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.
Understanding Tooth Shade — The VITA Scale
Dental professionals in Welwyn 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.
