For a brighter smile, professional whitening is a well-evidenced, non-invasive first step. Practices in Castle Green tailor the concentration to your natural shade rather than a one-size-fits-all gel. Some patients whiten in one appointment; others prefer the slower, gentler take-home route.
How Tooth Colour Is Measured
The VITA guide gives whitening an objective before-and-after in Castle Green: 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.

Sensitivity, Aftercare and Keeping Results
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.
Whitened enamel re-stains fastest in the first couple of days, so ease off coffee, tea and red wine. With sensible maintenance the shade holds for one to two years before a quick refresh.
