Professional teeth whitening uses a bleaching agent, typically hydrogen or carbamide peroxide, to break down stains within the tooth enamel — one of the most conservative cosmetic dental treatments available, since it doesn't remove or alter any healthy tooth structure.

Whitening works best on healthy teeth with no untreated cavities or gum disease, since these need to be addressed first. It isn't recommended during pregnancy or breastfeeding, and results vary depending on the type of staining — surface stains from tea, coffee, or tobacco respond well, while some deeper or trauma-related discolouration may need a different approach entirely. Existing crowns, veneers, or fillings also won't change shade, worth knowing if you're whitening around existing dental work.
Before starting, Dr. Dhara Patel checks that your teeth and gums are healthy enough for whitening. The gums and soft tissue are protected, and a professional-strength whitening gel is applied to the teeth for a controlled period — professional treatment uses a significantly higher concentration than over-the-counter kits, which is why results are faster and more even.
Mild, temporary sensitivity to hot or cold and some gum irritation are the most common side effects, and usually settle within a day or two. Results commonly last one to three years depending on diet and habits — coffee, tea, red wine, and tobacco all contribute to staining returning faster.
Dr. Dhara Patel checks your oral health thoroughly before recommending whitening, so you get a safe, honest assessment rather than a one-size-fits-all treatment. Read more about Dr. Patel's credentials and experience.
