Getting enough rest is essential for overall health—but did you know that poor sleep can also harm your teeth and gums? While it might not be the first thing you associate with a restless night, sleep (or the lack of it) plays a major role in your oral health.

Sleep and Your Immune System

When you don’t get enough rest, your immune system becomes compromised. This can make it harder for your body to fight off the bacteria that cause gum disease. Studies have shown that people who sleep fewer than six hours per night are more likely to experience gingivitis and periodontitis.

Sleep deprivation also leads to elevated levels of stress hormones, which can trigger inflammation throughout the body—including in your gums.

Teeth Grinding and Sleep Disorders

Sleep-related disorders, like bruxism (teeth grinding) and sleep apnea, can have a direct and damaging effect on your teeth.

Bruxism often occurs at night and can wear down enamel, cause jaw pain, and even lead to cracked teeth. You might not even realize you’re grinding until your dentist points it out during a check-up.

Sleep apnea, a condition where breathing temporarily stops during sleep, is associated with a dry mouth, bad breath, and higher risk for gum disease. It can also be linked to nighttime teeth grinding.

Dry Mouth and Sleep Habits

If you sleep with your mouth open or snore frequently, you’re likely to wake up with a dry mouth. Saliva is essential for neutralizing acids and washing away food particles. Without it, bacteria thrive—and that means a higher risk for cavities and bad breath.

Tips for Protecting Your Teeth While You Sleep

• Stick to a regular sleep schedule
• Avoid caffeine or alcohol close to bedtime
• Use a humidifier to combat dry air
• Talk to your dentist about a custom nightguard if you grind your teeth
• If you suspect sleep apnea, consult your physician

The Takeaway

Sleep isn’t just restorative for your body—it’s also critical for your mouth. Good sleep supports a healthy immune system, reduces your risk for gum disease, and helps prevent nighttime habits that can harm your teeth. So if you want a healthy smile, don’t just brush and floss—get some sleep, too. Learn more by scheduling an appointment today.
