Professional Whitening in Cardiff
Professional teeth whitening is one of the most effective ways to enhance your smile. Unlike shop-bought products, dentist-supervised whitening uses stronger, professionally formulated gels with custom-fitted trays for even, safe results.
Why choose professional whitening? Dentists assess your teeth first to ensure whitening is appropriate and identify any issues that need addressing. Custom trays protect your gums and ensure the whitening gel contacts your teeth evenly.
Results typically last years with proper care. Avoiding heavily staining foods and drinks, maintaining good oral hygiene, and occasional top-up treatments help keep your smile bright for the long term.
