Sleep Apnea Could Contribute to Weakened Bones and Teeth



A recent small study suggests that people with sleep apnea — a condition where breathing briefly and repeatedly stops during sleep — may be at greater risk for low bone density.

Published in The Journal of Craniomandibular and Sleep Practice, the study used cone beam – a type of X-ray – to measure bone density in the head and neck of 38 adults receiving orthodontic treatment, half of whom had obstructive sleep apnea. The results revealed that individuals with sleep apnea had significantly lower bone density in these areas compared to those without the condition.

Researchers believe that sleep apnea can lead to lower oxygen levels and increased inflammation in the body, disrupting the natural cycle of bone breakdown and renewal. This disruption could lead to decreased bone density, heightening the risk of fractures and contributing to issues like loose teeth.

Bone density screening is a key component of routine health care, particularly for women over 65, to assess and manage bone health.

Authors of the study conclude that more research is needed with larger sample sizes.
