If you last went to your dentist 20+ years ago how do you know ya teeth aren't full of holes...
But assuming they're not that's pretty good, no extra points for wisdom teeth still in though
Never had any holes either, I brush once a day, just before bed... at least 85% of the time
Mouthwash, once 10 years ago
Floss maybe twice a year
Bonus points for low maintenance
Making up the rules as I go along
