What changes after a whitening session
Professional whitening treatment lightens natural tooth enamel by several shades, reducing stains from coffee, tea, red wine, and everyday habits. The result is noticeable within one appointment, though the exact shade improvement depends on your starting colour and enamel condition. Teeth respond differently, so results vary between individuals. While the treatment is effective, it does not change the colour of crowns, veneers, or fillings. Existing dental work remains its original shade, which may become more visible once surrounding teeth are lighter. Understanding this helps set realistic expectations before you begin.
Common mistakes that reduce effectiveness
Many people expect instant Hollywood-white results or assume whitening works on all tooth discolouration. Internal staining from medication, trauma, or ageing often responds poorly to surface whitening. Overuse of home kits or poorly timed treatments can weaken enamel and increase sensitivity without improving colour. Some clients whiten immediately before veneers or crowns are fitted, creating a mismatch. Timing matters. Whitening is most effective when completed before restorative work, so new dental work can be colour-matched to your lighter teeth. We discuss these details during consultation to avoid disappointment and wasted effort.
Frequently Asked Questions
Can whitening damage my teeth?
When performed correctly on healthy teeth, professional whitening does not damage enamel. The treatment uses hydrogen peroxide or carbamide peroxide, both of which have been studied extensively and are considered safe. Temporary sensitivity is common but not harmful. Overuse or improper application can weaken enamel, which is why professional oversight matters. We assess your dental health first and follow protocols designed to minimise risk. If your teeth are already compromised by decay or erosion, whitening may not be appropriate until those issues are resolved. Safety depends on starting with sound enamel and following guidance carefully.
Will my teeth stay white permanently?
No. Whitening lightens existing stains but does not prevent new ones. Your teeth will gradually darken again as you eat, drink, and age. How quickly this happens varies. Someone who drinks black coffee daily and smokes will see colour return faster than someone with lighter habits. Touch-up treatments every six to twelve months maintain brightness without repeating the full process. Good oral hygiene, regular brushing, and limiting staining foods help extend results. Whitening is effective, but it requires ongoing maintenance if you want to keep teeth looking their brightest over the long term.
Does it work on crowns or veneers?
No. Whitening only affects natural tooth enamel. Crowns, veneers, bonding, and fillings do not change colour during treatment. If you have visible dental work on your front teeth, whitening the surrounding natural teeth may create a noticeable contrast. This is why we recommend completing whitening before having restorative work done, so your dentist can match new materials to your lighter shade. If you already have dental work and want a uniform appearance, replacing the restorations after whitening may be necessary. We discuss this during consultation so you understand what to expect and can plan accordingly.
How soon can I eat or drink after treatment?
You can eat and drink immediately, but we recommend avoiding heavily coloured foods and drinks for the first twenty-four to forty-eight hours. Tea, coffee, red wine, curry, beetroot, and dark sauces can re-stain teeth while pores in the enamel are still open. Sticking to lighter-coloured foods during this period helps lock in your results. Sensitivity may also make very hot or cold items uncomfortable for a day or two. After the first couple of days, you can return to your normal diet, though moderating staining habits will help your results last longer. There is no strict ban, just practical advice to protect your investment.
