Good dentist in Mexico?

I live in UK, me & my husband need to get rid of a root canal & probably need tooth extraction as we have some very large Amalgam fillings; so probably need cavitation cleaning as well as Amalgam removals. We want dentist who use safest material ( eg non metal & non radioactive filling)

As the good dentists in UK are very expensive, we want to go Mexico instead.

Any good mexico dentists you recommend?

Many thanks for your infos
