Brighten Your Smile & Boost Your Confidence!
A brighter smile can make a real difference to how you feel about your appearance. Over time, teeth can become darker or stained due to age, coffee, tea, red wine, smoking, and other everyday habits. Professional teeth whitening at Ardent Sidcup can help reduce these stains and give your smile a noticeably lighter appearance.
Our teeth whitening treatment is designed around your teeth, gums, and desired results. Before whitening, our dental team will assess your oral health to make sure the treatment is suitable for you and explain what you can realistically expect.
Teeth whitening is a cosmetic dental treatment that lightens the colour of natural teeth and helps reduce visible staining. Professional whitening products commonly use peroxide-based ingredients, which work by breaking down compounds responsible for darker tooth colour.
Whitening can be particularly helpful for surface staining caused by coffee, tea, red wine, smoking, and the natural effects of aging. The results aren’t permanent, but good oral hygiene and following professional aftercare advice can help your brighter smile last longer.
Professional teeth whitening can noticeably brighten your smile, with treatment time depending on your chosen whitening option and the level of staining.
A brighter smile can help you feel more comfortable when smiling, meeting people, attending events, or simply going about your day.
When whitening is carried out under professional dental guidance, our dental team can assess your teeth and gums and help ensure the treatment is carried out appropriately. This also helps reduce the risk of problems caused by incorrect use of strong whitening products.
We can recommend a whitening approach based on your teeth, existing staining, sensitivity, and the level of brightness you want to achieve.

The exact process depends on the whitening option recommended for you. Our dental team will first check that your teeth and gums are healthy enough for treatment.
Our dental team will examine your teeth and gums, discuss your concerns, and check whether professional teeth whitening is suitable for you.
We’ll explain the treatment and prepare your teeth and gums. If you are using whitening trays, we’ll check them to ensure they fit comfortably.
A professional whitening gel is applied according to the recommended treatment plan. Depending on the option chosen, treatment may be completed at the practice or continued at home using professionally provided whitening trays.
We’ll provide advice on caring for your teeth after whitening, including ways to manage temporary sensitivity and help maintain your results.
Teeth whitening is generally most suitable for people with healthy teeth and gums. Existing decay, gum problems, or other dental concerns may need to be treated before whitening.
Coffee, tea, red wine, smoking, and aging can all contribute to tooth discoloration. Professional whitening can help reduce many of these external stains and brighten natural teeth.
Whitening changes the colour of natural tooth structure. It won't whiten crowns, veneers, fillings, dentures, or implants, so we'll consider any existing restorations before recommending treatment.
People with significant tooth sensitivity, untreated decay, unhealthy gums, or certain types of intrinsic staining may not be suitable candidates. We can recommend another cosmetic option where appropriate.

Our dental team takes the time to understand your smile goals and recommend treatment based on your individual needs.

Professional teeth whitening is generally considered safe when the treatment is suitable for you and used according to our dental team’s instructions. Temporary tooth sensitivity or gum irritation can occur, but we can advise you on managing these effects.
Treatment time depends on the whitening method. In-practice whitening can often be completed during a single appointment, while dentist-provided home whitening trays are normally used over a longer period according to the treatment plan we recommend.
Teeth whitening isn’t permanent. How long your results remain visible depends on factors including your diet, smoking habits, oral hygiene, and natural staining. Following our aftercare advice can help maintain your brighter smile.
