How Tooth Colour Is Measured
Dental professionals in Tywyn 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.
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.
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.
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.

How soon after braces can I whiten my teeth?
It's usually best to wait a few weeks after braces are removed so the gums settle and any residual bonding is cleaned off. Whitening after orthodontics is very common — many patients treat it as the finishing touch — but your dentist will confirm the right timing for your case.
Can I whiten my teeth if I'm under 18?
Professional teeth whitening is not recommended or legally performed on patients under 18 in the UK. The enamel of younger teeth is still maturing and is more susceptible to damage from whitening agents. Adults aged 18 and over in good dental health are eligible.
