If the dentist really cared about you taking good care of your teeth, s/he’d give you one of those expensive, electric toothbrushes when you leave … not a cheap, flimsy, plastic one with terrible bristles that you wouldn’t even use on your dog.
Maybe I’ll bring this up at my appointment in February.
My dentist recommended not to use those (versus a high quality manual one). People get lazy with electric toothbrushes, he said.
