Hello I bought a new brand of toothpaste and ever since using it,  after brushing my teeth i find that there is a thin layer of loose gum inside my mouth that comes off in chunks. I don’t know if the toothpaste has caused this problem or not but it is the only difference that has occurred in my dental routine. I find this irritating embarrassing and inconvenient as when I am at work I have to keep spitting out the loose fragments that I am finding during the day and sometimes it sticks to the corners of my mouth.

I just wandered if you had any ideas as to what this could be and what is causing it?

Kind regards
