I am a connoisseur of false teeth/dentures, metal platey things (which my cousin called "an instrument of torture), implants - with the screwey things in your gums, also because of bad bone density (£1,000) added.
All dentists will tell you lovely things but whilst I have had very little trouble with the implants - she needs to go to a very very good honest dentist (unfortunately private).
My whole lot, of the above cost me £10,000, but the £6,000 for the implants were worth it (at the moment). Oh and that was just for the four front teeth.
