How To Stop Grinding Teeth in Sleep? Bruxism Definition

Mar 15, 2017 · That''s not quite right, as teeth clenching and grinding may actually help some people keep their airways open at night. In this way, blocked airways are the root cause of both nighttime teeth grinding and obstructive sleep apnea (OSA) in some people. We''ve discussed the issues associated with teeth grinding already.
