That's a loaded question! Grinding (bruxism) has many contributing factors. From garden variety stress, degeneration of joints. ..yes arthritis! Very common in females, grinders, trauma like sports, even long ago,an estrogen deficiency correlation. However, treatable! Seen thousands. Add other structural issues like a bad bite, missing teeth, lack of the eye teeth contacting on lateral movements, extracting bicuspids for ortho! ( my personal pet peeve. Seen tens of thousands....official ortho board rules. ...perfectly acceptable, encouraged as it is mandatory for boards. Sure this will rustle feathers! Whatever, I am here for your elucidation. Other potential causes...use of SSRI antidepressants like Paxil, Prozac, etc. DO NOT STOP MEDS WITHOUT DOCTORS SUPERVISION. PLEASE TAKE AS DIRECTED BY MD!!! Randomly, airway compromise, forward head posture, sleep apnea. (Download Epworth scale to screen for sleep issues) and as a kicker we see many Ehlers-Danlos patients, a connective tissue disorder. Seeing an uptick in adult onset. It is a controversial issue, but my experience says it's the real deal. Rare thankfully.
There you have bruxism 101. I could write mountains after 75k patients. Key to treatment. Look for obvious, get at least a panoramic xray to evaluate joints. If your face is asymmetric or you have cross bite, big red flags. Treat with an orthotic...not a rubbery football guard. Custom fit, flat plane, lite posterior contact and
Cuspid discluusion. Doctor talk here...plus look for a lab the uses Astron vinyl. No BPA. No Methylmethacrylate Awesome product. Most large labs use. No palatal coverage. Lite incsical wrap about 1.5mm. Check my website drmickdds.com
Good luck, you will do fine. Caveat an oversell..ie a bunch of magic computer measuring. Caveat the undersell. If splint is bulky and uncomfortable you won't wear. Plus I worship airway space. Regards, Dr. Mick
