A. Many thanks for your email, nowadays it is a very common treatment to have silver(amalgam) fillings replaced with white fillings. my advice is to seek out a cosmetic dentist in your local area and arrange for a consultation where they will then quote for the work, usually per white filling the cost can be from £100 – £250. white fillings are technique sensitive so make sure the dentist uses rubber dam and has a reasonable amount of experience doing the procedure. if all is carried out to a good standard expect the fillings to last 7-10 years.
