Treatment Options for Bruxism
Conservative, non-invasive approaches should be the first-line treatment for bruxism, including oral appliances, behavioral strategies, and physical therapy techniques, with more invasive interventions reserved for refractory cases. 1, 2
First-Line Treatment Options
Oral Appliances
- Occlusal splints (bite plates) are the most common dental intervention for bruxism, primarily designed to protect teeth from damage caused by grinding/clenching 1, 3
- Hard full coverage stabilization splints have shown some efficacy, while splints that don't account for occlusion may cause adverse events like tooth movement 1
- Oral appliances should be fitted by qualified dental personnel with training in sleep medicine and/or sleep-related breathing disorders 1
Behavioral and Psychological Approaches
- Jaw exercises and jaw mobilization techniques to improve joint mobility and reduce pain 2
- Relaxation strategies and improvement of sleep hygiene 3
- Cognitive behavioral therapy (CBT) to address pain perception and management 2
- Patient education about the condition and avoidance of aggravating activities 1
Physical Therapy Techniques
- Trigger point therapy - manual pressure on specific muscle points to release tension 2
- Massage of masticatory muscles 1
- Postural exercises to improve head and neck alignment 2
- Heat and/or cold application to affected areas 1
Second-Line Treatment Options
Pharmacological Interventions
- Non-steroidal anti-inflammatory drugs (NSAIDs) for pain management 1
- Muscle relaxants for acute episodes 1
- Amitriptyline has shown some benefit in an open-label study 1
- Clonidine and clonazepam have shown efficacy in reducing bruxism, though with risk of dependency for clonazepam 4
Advanced Physical Therapy
- Combined approaches such as jaw exercise with jaw mobilization 2
- Manipulation with postural exercise for better functional results 2
- Acupuncture, which has moderate evidence for effectiveness 2
Interventions to Consider Cautiously
Botulinum Toxin Injections
- Botulinum toxin (Botox) injections to the masticatory muscles may reduce the frequency of bruxism 3
- However, concerns exist regarding possible adverse effects, and it is conditionally recommended against by some experts 2
- An RCT showed no benefit of Botulinum Toxin for TMD 1
Biofeedback
- May help patients develop awareness of muscle tension but has limited evidence 2
- Conditionally recommended against by some medical authorities 2
Low-Level Laser Therapy
- Insufficient evidence to support its use 1, 2
- Conditionally recommended against by the National Institutes of Health 2
Interventions to Avoid
Irreversible Treatments
- Irreversible occlusal adjustments have no basis in evidence for managing bruxism 3
- Permanent alterations to dentition are strongly recommended against 2
- Discectomy (surgical removal of the articular disc) is strongly recommended against 2
Special Considerations
Sleep Bruxism vs. Awake Bruxism
- Treatment approaches may differ based on whether bruxism occurs during sleep or wakefulness 5
- Sleep bruxism may have a protective role during sleep, such as in airway maintenance or stimulating saliva flow 3
Bruxism with TMD
- When bruxism coexists with temporomandibular disorders (TMD), treatment should address both conditions 1
- TMD issues related to oral appliances are usually transient, with pain decreasing with continued use 1
- Mandibular exercises may improve discomfort during adaptation to oral appliances 1
Monitoring and Follow-up
- Regular dental evaluations are necessary to assess treatment efficacy and potential side effects 1
- Long-term dental side effects of oral appliances may include decreases in overbite and overjet, and changes in incisor position 1
Treatment Algorithm
- Begin with conservative approaches: occlusal splints, behavioral strategies, and physical therapy 1, 2
- If insufficient response, consider adding pharmacological interventions for symptomatic relief 1
- For persistent cases, evaluate for more specialized interventions like botulinum toxin or biofeedback 2, 3
- Avoid irreversible treatments that permanently alter dentition or joint structures 2, 3
- Regularly reassess treatment efficacy and adjust approach as needed 2
Remember that bruxism itself does not always require treatment - management is only indicated when problems arise as a result of the condition 3, 6.
