If you’re looking for professional-strength teeth whitening gel, you’ve likely come across a number of options — from dentist-prescribed products to high street brands and online suppliers. It’s worth understanding what you’re actually buying.
The active ingredient in professional whitening gel is carbamide peroxide. It’s the same compound used by dentists, and it works by breaking down into hydrogen peroxide in contact with saliva, penetrating the tooth enamel and oxidising stain molecules from within. There’s no surface scrubbing, no abrasion — just a straightforward chemical process that’s been used safely in dentistry for decades.
Carbamide peroxide gel comes in different concentrations — typically 10%, 16%, and 22%. The higher the concentration, the faster the result, though sensitivity can increase at higher strengths. Most people achieve good results with 16% used overnight, or 22% used for shorter sessions.
There are plenty of carbamide peroxide gels on the market. Quality varies. What matters is the concentration, the formulation stability, and whether the supplier knows what they’re selling.
ProWhiteSmile has been supplying professional-strength whitening gel in the UK since 2004 — over twenty years, hundreds of thousands of customers. We’re a specialist supplier, not a general health and beauty retailer. Whitening gel is what we do.
