Do you have restless sleep or grind your teeth?
Teeth grinding often accompanies a set of other symptoms, including:
- Low blood pressure
- Chronic stuffy nose
- Temporomandibular dysfunction (TMD)
- Headaches or migraines
- Irritable bowel syndrome
- Tension headache
- Hyperventilation syndrome
- Chronic fatigue syndrome
- Cold feet and hands
- Depression or anxiety
- Brain fog, daytime sleepiness
- Allergies, skin rashes
Why would this be?
People who grind their teeth, often work or study long hours or report stressful family situations. Stress plays a part, but teeth grinding also reveals how people breathe during sleep. To put it more correctly, teeth grinding hints at a set of sleep disorders and lack of oxygen during sleep. It’s a little-known condition known as upper airway resistance syndrome. And it is far more common than you’d expect.
It’s estimated that 70 million Americans suffer from sleep disorders. You may ask how the number could be so big? Many people simply don’t know they are at risk. They also have sleep disorders that are hard to pick up and even define.
The relatively small number of diagnoses are those with obstructive sleep apnea, yet it’s estimated 1 billion people globally suffer from OSA.
Teeth grinding is often associated with a condition abbreviated as UARS – UPPER AIRWAY RESISTANCE SYNDROME.
Sleep tests reveal UARS is sleep interrupted with frequent respiratory effort related arousals (RERAs). It’s due to higher pressure in the airways that send a message of ‘choking’ to your brain. If you suffer RERAs all night long, your body cannot enter deep REM sleep.
UARS indicates sympathetic FLIGHT OR FLIGHT driven sleep. It is the little sister of sleep apnea, and we need to talk about it.
Imagine the sound of tooth enamel screeching against under 250 pounds of force per inch. That’s what dentists think when they see teeth grinding in patients. For a long time, I would prescribe a night splint to prevent damage to the teeth. Whilst guards can sometimes help, the real way to help a patient is to identify their breathing issue.
Do you or a family member suffer from teeth grinding?
