Your gums probably hurting. But hey, if it feels good, do as you please my man. Once in the morning, once at night. Seems to be working
Typically just once in the morning, unless I'm going out at night then twice. Cavity free for 31 years so I'll stick to what's working.
Being on the computer more seems to make me lazy and braindead so as long as I continue on in this state of life on Grasscity and Youtube and Ocarina of Time on Project 64, only when I go out.
Twice a day. When i was in my young teens I was depressed and didn't care too much about oral hygiene. Gave myself like 3 cavities and 2 were pretty deep nasty shit definitely learned from that.
