Teeth Whitening FAQs
Frequently asked questions
Is teeth whitening safe?
Yes, teeth whitening is safe when carried out by a qualified dentist. UK law requires it to be performed by a registered dentist, and all our dentists are GDC-registered, including a dentist with over 40 years of clinical experience. We’ve been providing teeth whitening for over 15 years, treating thousands of patients with an average improvement of 6-8 shades, with some patients achieving an improvement of up to 10 shades in a single visit.
How does in-clinic whitening compare to home whitening kits?
Unlike home trays, our treatment is carried out entirely in-clinic by a GDC-registered dentist. Here is how they compare:
- In-Clinic Laser: Dentist-administered 60-minute procedure, with advanced gum barrier protection for soft tissues; results visible from a single visit.
- Home Kits: Applied over several weeks, without in-clinic supervision or professional gum protection.
Is the consultation free, and can I be treated the same day?
Yes, your initial consultation is free, with no obligation to proceed. Before your appointment, our team will call you to go over the details and costs, so there are no surprises. On the day of the appointment, the dentist will check your suitability and perform a Predictive Shade Analysis — an assessment predicting your achievable results — before your full 60-minute laser treatment, which can be carried out the same day, in a single visit.
How much does teeth whitening cost?
Our laser teeth whitening starts at £199. This price covers your free dentist consultation, Predictive Shade Analysis, the in-chair treatment, and full aftercare advice.
Is teeth whitening painful?
No, teeth whitening itself isn’t painful. Some patients experience mild, temporary sensitivity during or shortly after treatment, which typically settles within a few hours. Because your gums are fully protected throughout by our advanced gum barrier formula, discomfort is kept to a minimum and in most cases, you are able to carry on with the rest of your day as normal.
Are your results trusted by patients?
Yes — we’re rated 4.9 out of 5 on Google from 1,917 reviews, and 4.9 out of 5 on Trustpilot from over 200 reviews, having treated more than 25,000 patients over 15 years, with every treatment carried out by a GDC-registered dentist.
