vibration cured pains??

[matraraced]

Okay, to start off, I'm not good with oral hygiene, I don't brush my teeth all too often, which had given me a problem with the left side of my mouth. I've had pains every time I opened my mouth for the past few months, but last night before I went to bed, I put a massager (vibrator for muscles) under my pillow and rested my head on it, after about 5 mins I started tasting blood, sat up and spit out a little blood that was mixed with a little brown stuff and surprisingly I could open my mouth with no pains! I'm just wondering if anyone could explain why that cured my mouth pain.
