pleasure & pain place

Looks inviting, spring-pretty doesn't it...but once I walked up that path this morning I was trembling ! Kind people inside but armed with mini builders' tools that they invade my mouth with and wait for my gargled yelps before they stop their mining....Dentists probably are very brave people really, given our experiences with them!
Has anyone enjoyed a non- invasive zap treatment by a dentist? It IS the 21 st century isn't it?
