Kelligirl 3 Posted April 22, 2012 I woke up day 4 of my pre-op liquid diet with my jaw and teeth hurting. This sucks, I have never done anything like this and my body and mind must be tripping not chewing. sleeping with a mouth guard and keeping my tongue on the roof of my mouth to not clinch my teeth. Anyone one else experience this? Share this post Link to post Share on other sites
