At Knights Dental Merthyr Tydfil, we provide professional teeth whitening for patients who want to improve the colour of their smile safely and predictably. Over time, teeth can become stained by food, drink, smoking and natural ageing. Our whitening treatments are designed to reduce discolouration while protecting the health of your teeth and gums.
Before treatment begins, your dentist will check that your teeth and gums are healthy and suitable for whitening. A personalised whitening plan is then created to ensure you achieve an even, natural looking result without damaging the enamel. All whitening is carried out using clinically approved products under professional supervision.
Teeth whitening works by applying a whitening gel that breaks down stains within the enamel. At your initial appointment, impressions or digital scans may be taken so that custom trays can be made to fit your teeth precisely. These trays allow the whitening gel to be applied evenly and safely.
You will be given clear instructions on how to use the whitening system at home over a set period of time. Your dentist will monitor progress and advise when treatment is complete. Some patients notice results within a few days, while others may need slightly longer depending on the level of staining.
Throughout treatment, we focus on minimising sensitivity and ensuring that your gums and enamel remain protected.
Professional whitening can significantly lighten the shade of your teeth and produce more even results than shop bought products. The final outcome depends on the type and depth of staining.
Most adults are suitable for whitening, but it may not be recommended if you have untreated decay, gum disease or certain dental restorations. Your dentist will assess your suitability before treatment.
Results can last for many months or longer depending on diet, smoking habits and oral hygiene. Occasional top up treatments can help maintain brightness.
Some patients experience temporary sensitivity during or after treatment. This usually settles quickly and can be managed with desensitising toothpaste or adjustments to the whitening schedule.
Whitening only affects natural tooth enamel. Crowns, veneers and fillings will not change colour and may need to be replaced to match your new shade if required.
Good brushing, flossing and avoiding strong staining foods and drinks can help keep your smile brighter for longer.
Professional whitening is carried out under dental supervision using regulated products that are designed to be both safe and effective. Custom trays also help ensure more even coverage and controlled results.
Results vary from person to person depending on the starting shade and the type of staining present. Your dentist will discuss realistic expectations and the level of improvement that can usually be achieved.
Yes, many patients choose to top up their whitening after some time to maintain brightness. Your dentist can advise when it is safe to repeat treatment based on your oral health.
