Treatment for Teeth Grinding (Bruxism)
Start with a hard full coverage stabilization splint fitted by a dentist trained in sleep medicine—this is your first-line treatment to protect teeth from grinding damage, combined with patient education about stress reduction, limiting caffeine, and improving sleep hygiene. 1, 2
Initial Conservative Management
Your primary approach should be non-invasive interventions before considering anything more aggressive:
- Occlusal splints (night guards) are the cornerstone dental intervention, designed to protect teeth from damage rather than eliminate the grinding itself 1, 2
- Hard full coverage stabilization splints have demonstrated efficacy, but the splint must properly account for occlusion or it may cause unwanted tooth movement 1
- The splint must be fitted by qualified dental personnel with training in sleep medicine and/or sleep-related breathing disorders 1, 2
- If you develop transient jaw discomfort with the appliance, this usually decreases with continued use; mandibular exercises can help during the adaptation period 1, 2
Patient education is essential and should include:
- Avoidance of aggravating activities like chewing gum or biting nails 1, 2
- Stress reduction techniques 1, 2
- Limiting caffeine intake 2
- Improving sleep hygiene 2
Physical therapy techniques provide significant benefit:
- Massage of masticatory muscles relieves associated muscle tension 1, 2
- Heat and/or cold application to affected areas helps manage symptoms 1, 2
- Supervised jaw exercises and stretching can reduce pain 3
When Conservative Treatment Isn't Enough
If you continue to have pain or muscle spasm despite the above measures:
Second-line pharmacological options:
- NSAIDs for pain management and inflammation 1, 2
- Muscle relaxants for acute episodes of muscle spasm 1, 2
- Amitriptyline has shown some benefit in open-label studies for chronic cases 1, 2
For refractory cases with specific indications:
- TRPV1 agonists (capsaicinoids) may help with oral motor control in select patients 1, 2
- Dopaminergic agents should be considered when bruxism is associated with movement disorders 1, 2, 4
Interventions to Use Cautiously or Avoid
Use with extreme caution (conditionally recommended against):
- Botulinum toxin injections to masticatory muscles may reduce grinding frequency, but an RCT showed no benefit for TMD and concerns exist about adverse effects 1, 2
- Biofeedback has limited evidence despite helping some patients develop awareness of muscle tension 1, 2
- Low-level laser therapy has insufficient evidence 1, 2
Never perform these interventions:
- Irreversible occlusal adjustments (permanent alterations to dentition) have no evidence basis and are strongly contraindicated 1, 2
- Discectomy (surgical removal of the articular disc) is strongly contraindicated 1, 2
Critical Pitfalls to Avoid
- Never proceed to invasive procedures before exhausting conservative options for at least 3-6 months 2, 3
- Never combine NSAIDs with opioids—this carries significant risk without clear additional benefit 2, 3
- Never perform irreversible dental procedures without clear indication, as damage to teeth from bruxism is irreversible but the underlying cause must be treated to avoid further problems 1, 2, 5
When to Refer to Specialists
Primary referral pathway:
- Refer to a dentist with training in temporomandibular disorders and sleep medicine as your first specialist 1, 2
- Provide complete medical history including medications, associated conditions (sleep apnea, movement disorders, chronic pain), and psychological comorbidities (anxiety, depression, stress) 1, 2
Secondary specialist referrals:
- Consider a pain management specialist or multidisciplinary pain team when patients have intractable pain unresponsive to dental interventions 1, 2, 3
- Physical therapist with TMJ expertise for manual trigger point therapy, which provides substantial pain reduction 3
Special Considerations
- When bruxism coexists with temporomandibular disorders, treat both conditions simultaneously 1, 2
- Regular dental evaluations are necessary to assess treatment efficacy and monitor for potential side effects 1, 2
- Long-term use of oral appliances may cause decreases in overbite and overjet, and changes in incisor position 1, 2
- Bruxism occurs in approximately 15% of children and up to 96% of adults, with stress, anxiety, and genetic disposition being dominant factors 6, 7
- In children, management typically consists of observation and reassurance rather than aggressive intervention 6
