Tooth-clenching and mouthguards (?) while lifting
When I’m lifting near my maximum, I involuntarily clench my teeth, really hard. It’s started to cause pain in a molar identical to pain I’ve had when I’m clenching a lot because I’m stressed (last time was during the peak of the pandemic).
My dentist has put me in a nightguard in the past and now in Invisalign retainers at night. I asked him about the pain and whether I should be using an athletic mouthguard while lifting. He said it’s a good idea, and that I could try the inexpensive stock ones you buy OTC.
So, for fellow clenchers:
Do you get tooth or jaw pain when you’re lifting heavy?
Have you tried a mouthguard? Does it help?
How do you pick the right OTC mouthguard? Like most things lifting related, they seem to be “one size fits all,” but men’s jaws are typically wider than women’s, so I don’t see how even the ones you “boil and bite” to kind-of-customize could fit some 6’4” 250lb dude and 5’3” 125lb me.
Were you able to make the boil and bite kind work, or did you have to get custom? I’m sure my dentist will do a custom one if I want, but he’s both a very good dentist and is in no hurry to convince me to spend on things I don’t need. The fact that he thinks it’s OK to try an OTC one is making me lean that way.
Any advice appreciated.
