Many people grind their teeth for years without knowing it — often it’s a partner or a dentist who notices first. Left unaddressed, nighttime grinding (bruxism) can wear down enamel, damage restorations, and trigger chronic jaw and head pain.
Signs You Might Be Grinding
- Waking up with a sore, tight, or clicking jaw
- Frequent dull headaches, especially near the temples, first thing in the morning
- Flattened, chipped, or worn-looking teeth
- Increased tooth sensitivity, especially to cold
- A partner mentioning grinding or clenching sounds during sleep
- Indentations along the tongue or cheek tissue
Because bruxism happens during sleep, many people only find out during a routine dental exam, when a dentist spots the telltale wear patterns on the biting surfaces of the teeth.
What Causes Nighttime Grinding
- Stress and anxiety are among the most common triggers — grinding often spikes during high-stress periods
- Sleep disorders, particularly obstructive sleep apnea, are strongly linked to bruxism; the grinding can be the body’s response to a partially blocked airway
- Misaligned bite or missing teeth can cause the jaw to shift into positions that encourage grinding
- Certain medications, including some antidepressants, and stimulants like caffeine and nicotine, can increase grinding frequency
Treatment Options
- Night guards: A custom-fitted night guard creates a physical barrier between the upper and lower teeth, absorbing the force of grinding and protecting enamel from further wear.
- Addressing sleep apnea: If grinding is connected to a sleep breathing disorder, treating the underlying apnea often reduces or eliminates the grinding as well.
- Stress management: Regular exercise, meditation, or jaw-relaxation exercises before bed can reduce grinding frequency for stress-related cases.
- Bite correction: In cases tied to misalignment, orthodontic treatment or dental restorations may address the root cause.
When to Bring It Up
If you’re waking up with jaw soreness or morning headaches on a regular basis, mention it at your next cleaning — even if you’re not certain it’s grinding. A quick look at your enamel wear patterns can usually confirm it, and a night guard is a simple, affordable way to prevent damage that’s much more expensive to fix later.
