Why did I suddenly begin grinding my teeth, bigtime. Why am I doing this in the daytime, not just when asleep?

I remember I used to grind teeth too overnight. The dentist says it can be from stress.

try a vitamin b complex, give it a couple of weeks to kick in, maybe a little meditation 3 to 4 times a day 2-3 minutes each time

You can get a rubber thingy to wear on your top teeth, so that while you wait to figure out the stresses you are under, at least your teeth will be saved. Ask the dentist to make one for you--for your very own teeth. I think they cost up to $400--maybe less. And maybe it will be covered by insurance. I think it's worth it, though. Stops teeth from getting cracked.

I grind mind day and night, too. It's an anxiety thing.

I should add, this thing for your top teeth is for night time--grinding your teeth in the day is something at least you can be aware of and maybe control.

It's all about stress and anxiety. You can control it during the day be forcing yourself to relax your mouth and jaw but at night you have no control, which is why Dentists prescribe the mouth guard to wear during sleep, to protect your teeth. You can wear the guard by day if you need to, but it's difficult to speak. It's crucial you stop the process pronto or risk jaw pain and trauma to the joints, which can cause clicking and popping sounds. That is a horrid side effect! I exercise everyday to keep my body relaxed and it helps especially if you exercise in the evening, not too much, just a little. The grinding is normal animal behavior that comes and goes with life's trials, but you need to get a grip on it.

The nightguards cost anywhere from $400.00 to 750.00. They are all the same, so protest if it's over $400.00! Insurance sometimes pays, most of the time not a covered benefit. Do not bother to get one if you know you'll end up throwing it in a drawer. You have to wear it!

You should be very careful with this. Teeth grinding can often cause much more serious issues, such as TMD or TMJ
