What is bruxism?
Bruxism describes repetitive jaw muscle activity that makes the teeth clench together or grind side to side. There are two main forms:
- Sleep bruxism happens unconsciously at night, often in short bursts. Grinding may be noisy enough to wake a partner.
- Awake bruxism is usually silent clenching during concentration, driving, exercise or stress, such as while working at a computer.
Occasional clenching is common and harmless. It becomes a dental problem when the forces are strong or frequent enough to damage teeth, restorations, gums or the jaw joint.
Signs your teeth are paying the price
- Flat, shiny or shortened biting edges, especially on the canines and front teeth
- Small chips, craze lines or a cracked tooth
- Notches at the gumline and sensitive teeth
- Fillings or crowns that break or come loose repeatedly
- Enlarged, tender jaw muscles at the angle of the jaw
- Morning headaches, ear-area aching or jaw stiffness
- Scalloped edges on the tongue or a white ridge along the cheek
Who needs treatment, and when to look elsewhere
Treatment is worthwhile when bruxism is causing wear, pain, damage to dental work, or jaw joint symptoms. People who have implants or extensive restorations benefit from early protection because these can be overloaded by heavy grinding.
Bruxism can be linked to snoring, sleep apnea, certain medications, caffeine, alcohol and smoking. If your history suggests a sleep breathing problem, such as loud snoring, gasping or daytime sleepiness, we will advise you to see a sleep medicine doctor as well, since treating the airway can matter as much as protecting the teeth. Grinding in young children is common and often outgrown; we monitor it during children's dental visits.
Our step-by-step approach
- Detailed history. We ask about sleep, stress, caffeine, medications, headaches and what others have noticed.
- Examination. We check tooth wear patterns, palpate jaw muscles, test joint movement and examine restorations. Images from our Q-ray intraoral camera help you see cracks and worn areas for yourself.
- Protection. For sleep bruxism, a custom night guard is usually the first measure. It takes the wear and spreads forces across the arch.
- Muscle relief. Where muscles are sore, sessions with our TMJ physical therapy device aim to reduce pain and inflammation, combined with home stretching and warmth.
- Habit retraining. For awake clenching we teach a simple check: lips closed, teeth apart, tongue resting lightly on the palate. Phone reminders or small stickers on your monitor help build the habit.
- Repair. Once grinding is under control, worn or broken teeth can be rebuilt with aesthetic bonded restorations or crowns. Restoring first, without protection, risks the new work being damaged.
Ongoing care
Bruxism is managed rather than cured. Regular reviews let us check the guard, look for new wear and adjust the plan when life circumstances change. Many patients notice that symptoms rise during busy or stressful periods; recognising this pattern is useful in itself. Reducing caffeine late in the day, limiting alcohol, and building a calmer pre-sleep routine can all help.
Why we protect before we rebuild
Patients with badly worn front teeth often ask to have them restored straight away, and we understand why. But if heavy grinding continues, new bonding or crowns face the same forces that wore down the natural enamel. Wearing a guard for a period first shows us how well the grinding is controlled and allows the jaw muscles to settle into a comfortable position. That position is then used as the reference for restorations, which gives the repair work a more stable foundation. For patients with extensive wear, this planning may lead into a broader full-mouth reconstruction, always discussed step by step.
Risks and limitations
No dental treatment can switch off the brain's grinding activity. Night guards wear and need occasional replacement. Bite adjustments are irreversible and are only considered in limited situations. Botulinum toxin injections for jaw muscles are sometimes discussed for bruxism; they are a medical procedure with their own risks and are not part of our standard treatment, so ask us if you want to talk through referral options.
Why Gunpo patients trust us with bruxism care
We look at bruxism as part of your overall health, in line with our clinic's whole-body philosophy, and we explain clearly what needs protecting now and what can wait. Diagnosis, guard fitting, physical therapy and restorative repair are all available in one clinic near Sanbon Station, with evening hours on Mondays and Thursdays. If you suspect you grind your teeth, arrange an examination or learn about your first appointment.
