As someone dealing with some painful dental issues during lockdown over the past few months, I have to say, I approve of the endocannabinoid approach.
Dental pain is awful. I'm so sorry. I had a hospital-and-hydrocodone-worthy case of oral thrush a few years back and beyond losing the ability to speak...well, at all, for a time, I found myself slamming the counters with my fist so the new pain in my bruised arms took away from the roaring, unending pain in my mouth.
I can't imagine having that kind of pain for more than a day or two before being in a dangerous mental state with respect to my own personal safety.
I've always had a high pain-threshold, but recently I've been 'beside myself' with pain (and a ringing in the ears, driving me mad at night, at times). Cannabinoids have been hugely helpful.
Thankfully, I have managed to get an appointment with the dentist next week. But I've had to wait longer than I wanted for it.
Years ago, I snapped my leg in half. Tibia and Fibula cleanly snapped. Had Titanium plates put in. That was easier to deal with than dental pain. ;)
