Tooth Coloured Fillings

Dental practice at 40 Harley Street, Central London

At 40 Harley Street, we only use tooth-coloured fillings (composite fillings) as they are more aesthetically pleasing and are better for dental health than metal fillings. By using the latest materials and advanced techniques, our experienced dentists create functional restorations that are virtually indistinguishable from the filled tooth and neighbouring teeth. Composite fillings have numerous benefits including:

  • They restore the natural appearance of the tooth and are mercury free.
  • Composite fillings bond to the natural tooth which enables them to restore more of its original strength.
  • They require less removal of tooth structure, especially with new cavities, as the size of the access cavity made for the filling can be dramatically smaller.
  • Composite fillings do not expand and contract due to changes of the mouth’s temperature (as metal fillings do). This helps to protect your teeth from cracks and fracture.

If you need a very large filling, a porcelain inlay may be required. A temporary filling is placed while the inlay is constructed in the laboratory. When the inlay is ready, it is cemented in place.

Frequently asked questions

About tooth-coloured (composite) fillings at 40 Harley Street

  1. Why are composite fillings preferable to metal fillings?

    Tooth-coloured fillings are more aesthetically pleasing than metal fillings as they are virtually indistinguishable from the natural tooth that they fill. Silver fillings weaken the teeth, making them more susceptible to breaking and there are health concerns of the safety of mercury in fillings.

    Tooth-coloured fillings bond with the natural tooth which helps to restore its strength.

  2. Why do you only provide composite fillings?

    We believe that composite fillings are superior to other types of fillings. Providing the most advanced of products, procedures and techniques is an integral part of our ethos.

  3. What are composite fillings made of?

    They are made of a composite of resin mixed with clear glass particles. The composite does not react with the body’s tissues.

  4. Will the filling always be tooth coloured?

    Just like natural teeth, it is possible for a tooth-coloured filling to be discoloured by food, coffee, wine and smoking.

  5. How long do tooth-coloured fillings last?

    Tooth-coloured fillings are generally long lasting as they don’t expand and contract in the same way as metal fillings. However, their longevity will depend on their position within your mouth and how heavily your teeth come together when you bite.

Ten years ago I was told that I would need gum surgery. I went to 40 Harley Street for a second opinion. I was told that, with the correct care and attention, surgery could be avoided. I have been a patient ever since. The care and attention Dr Rezavandi has administered has kept my teeth and gums healthy.
I cannot thank him & his team enough.
