Yes, this is the normal routine.

As the others have said, brushing your dog's teeth will reduce the need
for repeated anesthesia for dental scaling and polishing. A child-soft
brush (or one of the Colgate battery operated brushes, as the brush head
is small; my guys like this type of brush) will work very well for a
Boston. Use a pet toothpaste (My Border Terriers go nuts over the
peanut butter flavor... with poultry flavor a distant second). Twice a
week for brushing is fine, but daily is better. You don't rinse the
dog's mouth out ; he'll swallow the toothpaste like a very young child
will do.... no harm. Frequent brushing will go a lo-o-o-o-o-o-o-o-ong
way toward controlling "Dog Breath".
