Hello,
I'm considering having this. I've always ground my teeth and carry so much tension in my jaw that it gives me headaches. I've woken up having bitten my cheek and lips and with raging headaches. I've also got a square face shape anyway but over time it's become even squarer due to the bruxism and I'm self-conscious about it.
I've just discovered that you can have botox in your jaw muscles to reduce the bruxism as well as face shape. Would be amazing for me if it works! Interested to hear if anyone has had this or can offer any advice.
