but then my teeth started often hurting and being sensitive for cold things or acidic things. I had never experience such sensitivity before.

so i went to the dentist and they said they could see such visible signs of wear that I must have been grinding during my sleep (I was single at the time).

Now I have worn the mouth guard for some years and am fine with it. The sensitivity of my teeth has largely gone away.

So to me having to deal with the annoyance of a night guard is well worth it to protect my teeth better.
