On the recommendation of Drew's periodontist, we bought a Sonic toothbrush and a water pick (for the betterment of his future implant). He got a set of extra heads for me and the girls to use. G thought it tickled, don't know if that means she liked it or not.
And we brushed M's teeth for the first time this evening. We're about 14 teeth late, but she acted like an old pro with the whole process: opened her mouth when Drew told her to, didn't chew on the bristles, laid there quietly until Drew was finished. Long may it last.
