There’s low level constant pain that’s not easily comparable to anything else, which gets worse the day after any adjustments are done. And make sure you get a retainer you can wear each night.
My mistake was not asking for an alternative retainer, and grinding teeth at night kept breaking my retainers until it got too expensive to keep getting new ones. Now I’ll have to get braces or Invisalign or something to redo the straightening.
Good news is, I can still eat better than I could before I got braces.
In other news, seeing the Ear, Nose, and Throat specialist about my sinuses ended up curing the grinding along with mouth breathing and swollen sinuses.
