If you really dont mind travelling, you should go to my dentist in Winersh, nr Wokingham. Robinspool dental Surgery. Its a private practice with much cheaper rates than normal private practices.
Ask for Sally.......she rides a GS 650 Twin.....Oh! And she is SWMBO!!!!!
I needed to get in with a new dentist just after Christmas and having not been for far to many years was amazed that I got in as an NHS patient with one in Etwall, just south of Derby.
they are really good, they'd have to be for me to be willing to go back as dentists scare the crap out of me.
