As Lynn remarked recently
"Finding a NHS - National Health Service - dentist to treat your pearly whites in the UK at the moment is like pulling teeth"
My dentist is housed in the middle storey of this building on the right-hand side of Borough Arcade, and I'm off this morning for a check-up. So long as you visit him twice a year, you'll remain registered.
The upper storey houses a gymnasium and the ground floor is occupied by a shop selling stationery, art & craft supplies and cheap printer ink.
