5. Teeth grinding and joint health
In most cases bruxism is mild. But, when it’s frequent and severe, grinding your teeth can aggravate the joints in your lower jaw, also known as the temporomandibular joints, or TMJs. This can lead to pain or tightness in the joint area, and even earaches and headaches.
Of course, bruxism is bad news for your teeth, too. The habit can wear down your enamel, cause increased tooth sensitivity, and result in chipped or broken teeth. “Some people are putting incredible forces on their teeth,” says dentist Ron Smith.
