Q. Hello. I have broken 50-60% of my two front teeth. I had a root canal treatment immediately and now after 7months I am looking for an excellent dentist to fix my teeth in London. Do you have any suggestions make? Also, I would like to ask you which would be better to put as a crown, a porcelain or a zirconium? I want a natural result but at the same time to be strong and long lasting. Thank you in advance for your help.,
