What Is Bruxism?

Bruxism is the involuntary grinding, gnashing, or clenching of teeth. It most commonly occurs during sleep (sleep bruxism) but can also happen while awake (awake bruxism), often triggered by stress or concentration.

How Common Is It?

Bruxism affects an estimated 8–10% of adults and is one of the most underdiagnosed dental conditions — because most people do it unconsciously.

Signs and Symptoms

What You May Notice

• Waking up with jaw soreness or stiffness

• Morning headaches, especially at the temples

• Tooth sensitivity that seems to come and go

• Chipped, cracked, or worn-down teeth

• Indentations on the tongue or inside of the cheek

What Dr. Kim May Find

• Flattened or polished tooth surfaces

• Enamel loss and exposed dentin

• Cracked fillings or fractured teeth

• Enlarged jaw muscles (masseter hypertrophy)

• TMJ tenderness on palpation

Why Is Bruxism So Damaging?

The forces generated during grinding can reach up to 250 pounds per square inch — far exceeding normal chewing forces. Over time, this causes:

• Severe enamel wear and tooth sensitivity

• Fractured teeth and failed restorations

• Bone loss around teeth

• TMJ damage and chronic pain

• Premature failure of crowns, veneers, and implants

What Triggers Bruxism?

Trigger Notes

Stress and anxiety Primary driver in most adults

Sleep disorders Strong association with sleep apnea

Caffeine and alcohol Increase nighttime muscle activity

Certain medications SSRIs and stimulants can worsen bruxism

Bite misalignment Uneven contacts provoke grinding patterns

Genetics Tends to run in families

Treatment at Remcon Prime Dental

1. Custom Occlusal Guard (Night Guard)

The most effective and immediate intervention — a precisely fitted hard acrylic appliance that protects teeth and reduces muscle load during sleep.

2. Occlusal Adjustment

If uneven bite contacts are contributing to grinding, selective reshaping of tooth surfaces can reduce the trigger.

3. Lifestyle Modifications

• Reduce caffeine and alcohol, especially in the evening

• Practice jaw relaxation exercises

• Apply warm compresses to jaw muscles before bed

• Be mindful of daytime clenching habits

4. Sleep Apnea Screening

If sleep apnea is suspected, Dr. Kim will recommend evaluation — treating the underlying sleep disorder can significantly reduce bruxism.

5. Restorative Repair

If bruxism has already caused damage, Dr. Kim can restore worn or fractured teeth with tooth-colored fillings, crowns, or veneers after the grinding is controlled.
