Mrs B kept getting a periodic tooth ache so went to the our dentist who we had and we were all private, nothing wrong that i can see was the answer, it came and went, back a couple of times, nothing that i can see every time, except the £25.00 for looking every time, in Spain it came back again, so in the dentist she went, one rear tooth was the problem and had to come out, 40€ plus small prescription for antibiotics.
The same dentist put a cap on one of mine and after almost £400.00 having this cap refitted, after it kept coming loose, many times, I told him to take it out, £50.00 job done.
A friend who owned a dentist supply company and wholesalers pointed out to me every dentist around the area that bought the cheapest products going from him, like many things for sale there are bad cheap rubbish items, and top notch expensive items, out of 20 dentists only 4 bought the best items.
