Whitening is a process where the tooth discolouration is ‘whitened’ to a lighter shade.
Tooth whitening and how it works
It removes the staining agent through chemical means. It is a safe procedure when carried out under professional supervision. Treatment results usually depend on the severity of the discolouration. Both vital (i.e. live) and non-vital teeth (e.g. tooth with nerve removed) can be bleached and may take several visits to complete. It is not effective on dental restorations such as amalgam fillings, metal or porcelain crowns, etc.ent.
Teeth can discolour for various reasons. The dentist will recommend the most ideal method based on your oral condition after an in-surgery examination to establish the cause and nature of your tooth discolouration, as well as provide you with more information on the various types of whitening procedures available, duration and frequency of treatment.

What our patients say
“We have been with our previous dentist for 37 years but the changes over recent years forced us to change. We chose Alvington House and could not be more pleased. Wish we had moved years ago! The organisation is professional and the care is calm and experienced. I hope we will be around for another 37 years with Alvington. Thank you to Mr Nigel Slattery and Sarah.”

“As a private patient with the practice, I could not be happier with the service I’ve received in the short time I’ve been coming here. Mr Soares is an absolute asset to the practice and made me feel heard from the get go. Which, for someone with anxiety over dental related anything, is a definite plus. Highly recommend this practice if you’ve the finances for private care.”
Rick Cole.
“Fantastic practice and people. On top of routine check-ups, Joel did teeth whitening and a crown for my front tooth that previously had root canal and filling. I’m so happy with the results and feel like I can smile properly again for the first time in years.”
Evan Doble.
“Being a very nervous dental patient, the prospect of a molar extraction was very daunting. I was seen on the same day as I phoned in in pain and my tooth was taken out within two days. Mr Surti was brilliant! I was amazed at how easy and painless it was compared to my awful childhood experiences. Very calm and professional and made every effort to squeeze me in as soon as possible. All the staff were brilliant. I highly recommend this dental practice and especially Mr Surti.”
