This happens to me when I'm having a bad day, I don't find the toothbrush a problem but the very strong taste of the toothpaste, I have started using children's milder taste toothpaste in the mornings and normal adult toothpaste in the evening and so far it seems to work for me.
My worst experience was at the dentist a few years ago when I had to have an impression for a crown, I had this putty stuff in my mouth, it was horrible, the tears were rolling down my face

Now I don't wear mascara when I visit the dentist
