Bruxism — involuntary grinding or clenching of teeth — affects about 10% of adults. Stress is the most common cause. Left untreated, it can prematurely wear down teeth and cause jaw pain. Your dentist in Sainte-Marthe-sur-le-Lac can help with a custom-made night guard.
Quick Answer
- Bruxism is involuntary teeth grinding or clenching, often at night
- Stress, anxiety, and sleep disorders are the main causes
- Signs include morning headaches, sore jaw, and worn teeth
- A night guard protects teeth and reduces muscle tension
- Treatment is covered by many dental insurance plans
Why Do People Grind Their Teeth?
Stress and Anxiety
Daily stress is the most common cause of bruxism. Tension often manifests as jaw clenching, particularly during sleep.
Sleep Disorders
Bruxism is often associated with sleep apnea and other sleep disorders.
Malocclusion
Misaligned teeth can contribute to grinding. Orthodontics may help in these cases.
Lifestyle Habits
Excessive caffeine, alcohol, or tobacco consumption increases the risk of bruxism.
Signs and Symptoms
- Frequent morning headaches
- Jaw pain or stiffness in the morning
- Flattened, cracked, or abnormally worn teeth
- Increased tooth sensitivity
- Nighttime grinding sounds (reported by partner)
- Ear pain without ear problems
Night Guard: When and Why
A night guard (occlusal splint) is a custom-molded acrylic appliance. It creates a barrier between upper and lower teeth, preventing wear and reducing pressure on jaw muscles and joints.
A custom guard made by your dentist is far more effective than generic pharmacy protectors, which can worsen symptoms if poorly fitted.
Frequently Asked Questions
Does a night guard cure bruxism?
No, it protects teeth and relieves symptoms but doesn't treat the cause. Stress management, physiotherapy, and sometimes medical follow-up may complement treatment.
How much does a night guard cost?
Costs range from $300 to $600 in Quebec. Most dental insurance plans cover a portion of this treatment.
Can I wear my guard every night?
Yes, the guard is designed for regular nightly use. It should be cleaned each morning and stored in its case.
