Once per day, as long as it’s before you go to bed, is probably enough. That’s the only time that I do it, and I haven’t had any more cavities since getting back into it as a regular habit. I also floss, then massage my gums by brushing a 2nd time, then finish up by rinsing with Act.
Brushing used to be a real drag for me, but after meeting several people who had to have all of their teeth removed, I made sure to straighten up my habit. The best thing to do is to take control of it. Buy a different brand of toothpaste than what your parents introduced you to. Many toothpastes are so sweet that they would hurt the roots of my teeth. Tom’s Of Maine feels so much nicer. Another thing that made me comfortable with brushing was to make sure that I only use toothbrushes with soft bristles, and also avoid any that look like medieval weapons.
The only thing now that causes me to not brush is that I’m afraid that I will get hungry while trying to fall asleep. So part of my brushing ritual is having a snack beforehand - usually a small amount of mixed nuts.
