Gum disease and nighttime teeth grinding: is there a connection?

This completed study looked at whether people with advanced gum disease (periodontitis) also grind or clench their teeth more during sleep. Researchers used a small portable device to measure muscle activity in the jaw over 24 hours in 40 adults, half with severe gum disease and half with healthy gums. The goal was to see if there is a link between gum disease and sleep bruxism, which could help guide future dental care.
