Is anyone brushing teeth daily?

I feel guilty but my health has made it impossible to brush their teeth like I used to. I used to do it once a day but now I have not done it at all.

I check their teeth and they are white but I feel guilty. How much is enough?
I was told 2 times a week minimum. Is this about right to others?

2 times a week is about right for me...just not going to do it everyday
