Bruxism is a common parafunctional activity characterized by repetitive jaw muscle activity, including clenching or grinding of the teeth.Although many children exhibit sleep bruxism at some stage of development, its presence does not automatically indicate the need for treatment.

One of the most debated questions in pediatric dentistry is whether myorelaxant splints (occlusal splints) should be prescribed to manage bruxism in growing children.
Current scientific evidence indicates that splints should not be considered a routine treatment for pediatric bruxism because their effectiveness remains uncertain, while craniofacial growth and tooth eruption require careful clinical consideration. Instead, management should focus on identifying associated factors, evaluating symptoms, and individualizing treatment according to each child's clinical presentation.

According to contemporary international consensus, sleep bruxism is a rhythmic or non-rhythmic masticatory muscle activity that may involve tooth grinding, clenching, bracing, or mandibular thrusting during sleep. In children, diagnosis is usually based on parental reports combined with clinical findings such as tooth wear, grinding sounds, muscle discomfort, or functional symptoms rather than instrumental confirmation alone.
Importantly, physiological tooth wear may occur during normal development, especially in the primary dentition. Therefore, tooth wear by itself should not be interpreted as definitive evidence that treatment is necessary. Clinical relevance depends on symptoms, progression, functional impairment, and associated risk factors.

The short answer is not routinely.
Occlusal splints are widely used in adult dentistry for several indications, particularly temporomandibular disorders and tooth protection. However, evidence supporting their effectiveness for treating bruxism in children remains limited and inconclusive.
Recent systematic reviews evaluating pediatric sleep bruxism found that occlusal splints did not demonstrate consistent superiority over observation or other conservative approaches. Some small clinical studies reported reductions in parental reports of grinding, whereas others using objective muscle activity measurements found no significant reduction in sleep bruxism activity after splint therapy. Consequently, current evidence does not justify prescribing splints as the standard treatment for every child with bruxism.
The International Association of Paediatric Dentistry (IAPD) recognizes that occlusal splints may be included among individualized management options, but emphasizes that treatment should be based on comprehensive diagnosis rather than the presence of tooth grinding alone. Similarly, contemporary pediatric literature stresses that growth and continuous dental eruption require close monitoring whenever an intraoral appliance is used.

The following table summarizes the current clinical position regarding occlusal splints in pediatric patients.
| Clinical Situation | Current Evidence-Based Interpretation |
|---|---|
| Asymptomatic sleep bruxism | Routine splint therapy is not recommended; periodic observation is generally preferred. |
| Progressive tooth wear with functional concern | A splint may be considered individually for tooth protection after comprehensive assessment. |
| Muscle pain or temporomandibular symptoms | Management should prioritize diagnosis of the underlying condition; splints are only one possible reversible therapy. |
| Mixed dentition and active eruption | Appliances require frequent monitoring and adjustment because dentition and occlusion are continuously changing. |
| Grinding without clinical damage | Education, monitoring, and evaluation of associated factors usually provide greater clinical value than immediate appliance therapy. |
Although splints are not routinely indicated, there are selected situations where an occlusal appliance may be considered by a pediatric dentist after careful evaluation.
Potential indications include:
▪️ Severe and progressive tooth wear with risk of structural damage.
▪️ Documented functional symptoms associated with excessive parafunctional activity.
▪️ Children presenting with painful masticatory muscle overload when a reversible appliance is considered appropriate within a broader management plan.
▪️ Situations where the primary objective is tooth protection rather than elimination of bruxism.
These indications should never be interpreted as automatic criteria. The decision depends on growth stage, dentition, eruption pattern, occlusal development, symptoms, and the presence of contributing medical or sleep-related conditions.

Unlike adults, children experience continuous craniofacial growth and dental eruption. This biological characteristic represents the principal limitation of prolonged occlusal appliance therapy.
A splint fabricated during one developmental stage may gradually lose adaptation as teeth erupt or exfoliate. Poor adaptation may alter occlusal contacts or reduce appliance effectiveness, making regular clinical follow-up essential whenever a splint is prescribed. For this reason, pediatric occlusal splints should be regarded as carefully monitored reversible appliances rather than long-term universal therapy.

The current literature demonstrates an important distinction between protecting the dentition and treating the bruxism itself. Occlusal splints may theoretically reduce mechanical consequences of grinding by distributing occlusal forces and protecting tooth surfaces; however, this does not necessarily mean they reduce the underlying masticatory muscle activity responsible for sleep bruxism.
Systematic reviews consistently conclude that the quality of available pediatric evidence is low and that treatment protocols remain insufficiently supported by robust randomized clinical trials. The most recent umbrella and systematic reviews emphasize that associated factors—including sleep disturbances, respiratory conditions, psychosocial influences, and individual clinical characteristics—should receive greater attention than routine appliance therapy. Therefore, contemporary pediatric dentistry favors an individualized, conservative, and evidence-based approach rather than universal splint prescription.
✍️ Conclusion
Myorelaxant splints are not routinely recommended for treating bruxism in children. Current scientific evidence does not demonstrate sufficient consistency to support their universal use as first-line therapy.
When clinically indicated, an occlusal splint should be prescribed primarily as a reversible protective intervention, not as a guaranteed treatment capable of eliminating pediatric bruxism. Comprehensive diagnosis, identification of associated factors, and periodic monitoring remain the foundation of evidence-based management in growing patients.
🎯 Clinical Recommendations
▪️ Do not prescribe an occlusal splint solely because parents report nocturnal tooth grinding.
▪️ Assess tooth wear progression, muscle symptoms, TMJ function, sleep history, and respiratory factors before deciding on treatment.
▪️ Consider splints only when there is a clear clinical objective, particularly protection of dental structures or management of specific reversible symptoms.
▪️ Schedule regular follow-up visits to monitor appliance fit during primary and mixed dentition, adapting the appliance as eruption and growth occur.
▪️ Refer for pediatric or sleep evaluation when clinical findings suggest obstructive sleep disorders or relevant systemic contributing factors.
