I have been grinding my teeth for years. Likely before I had teeth. I have woken up people staying in another room with my grinding. I hold my tension in my jaw, neck and shoulders. And I've had tension. I'm all about tension.
Recently I went to a new dentist. She took one look at me trying to open my mouth and asked about my grinding teeth. She told me I have worn my back teeth to almost nothing and immediately sent me to a physiotherapist for my jaw. I was hesitant. It seemed to be an overreaction. I mean, I've been grinding my teeth for years. Surely it's not that big of a deal.
The first appointment of physio was awesome. I learned that my top and bottom teeth are not supposed to touch when I am relaxed. I learned that I can actually open my mouth way wider than I thought. Now, I'm a person who can fit her fist in her mouth, so this is really funny to me. But at the beginning of the session, I could open my mouth 35mm and at the end, I could open it 50mm.
By the end of this, I will likely be able to put a whole Big Mac in my mouth. It's going to be awesome!
