A recent study which looked in to the relationship between smoking and gum disease was surprised to find out how much a person sleeps may also impact their oral health. The study of 219 workers in 1999 and again in 2003, which examined the health status and lifestyle factors (e.g.: exercise, smoking, stress and the hours of sleep) revealed that the 2 most significant factors which influenced the development of periodontal disease were smoking and the lack of sleep. The results suggest that getting more sleep may help people improve and protect their oral health.
