Hi,
Sweetie got her teeth cleaned today, too. She hates the PetzLife stuff as well (it's the mint flavor she hates - maybe your Max also). I have started her on a program called Ora-Vet (
www.oravet.com). It's some kind of sealant that you put on once a week with a swab - evidently you just have to get it close and their saliva distributes it (like PetzLife). It's not too expensive ($27 for 8(or 16 sez my vet) weeks worth). If it saves them from having to anesthesize her to clean her teeth it will be well worth it.
Hope Max did well with his vet visit as well.
Cyndi
