Its always been a problem with my enamel. Thats what I was hoping would get better. I've never really had a problem with my gums, except for the fact that they are receeding, and I haven't noticed any improvements with that yet. Do you think I should stop if it is the enamel? I still OP for around 8-10 mins in the morning (I cut it down in time), but haven't noticed any improvements with that yet either.
