I haven't brushed normally in two days, and i had to rush through it today (i lost track of time at camp). I tried to get more stuff off with my finger afterwards. Will my teeth be okay?

I'm sure they'll be fine. Just don't let them go for too long. First chance that you have some extra time, get out there and brush the heck out of them. You'll catch back up ! :)

You need to keep up with brushing your teeth it isn't good if you make that a habit.

You need to brush your teeth thoroughly. Plaques may build up in between your teeth as you won't be able to reach that area with your finger. If you ate candies or sweets, your teeth will decay if you don't brush.
