Understanding when it is a concern and when orthodontic assessment may help guides parents toward appropriate action.

Bruxism — the involuntary grinding or clenching of teeth — is one of the most prevalent paediatric oral conditions. Studies estimate that between 14% and 38% of children grind their teeth at some point during childhood, with the highest prevalence in the 3 to 10 age range. It is more common in children than in adults, and it frequently runs in families, suggesting a genetic component alongside environmental triggers. Many parents first become aware of it when they hear the grinding sound during sleep — a noise that is often far more alarming to parents than it is clinically significant for the child. ## Causes — stress, occlusal interference, sleep disorders The causes of childhood bruxism are multifactorial. Psychological stress is a significant driver — anxiety about school, family changes, or life events can manifest as nocturnal grinding even in young children who cannot articulate their feelings. Occlusal factors — particularly during the mixed dentition stage when baby and adult teeth coexist — may trigger grinding as the jaw attempts to find a comfortable resting position. Sleep disorders including sleep apnoea and restless leg syndrome have a well-documented association with bruxism; if a child grinds and also snores heavily or seems unrefreshed in the mornings, a sleep assessment may be warranted. Some medications, including certain stimulants used in ADHD management, are associated with bruxism as a side effect. ## When childhood bruxism resolves vs when to act The majority of childhood bruxism resolves spontaneously, particularly the type that begins during the mixed dentition phase. As permanent teeth fully erupt and the bite stabilises, many children stop grinding without any intervention. Monitoring is reasonable for mild cases. More active management is warranted if: grinding is severe enough to cause visible tooth wear on permanent teeth; the child complains of jaw pain, headaches on waking, or facial muscle soreness; sleep is significantly disrupted; or the grinding appears to be associated with unmanaged anxiety. Resolution is common by the early teenage years in those who began grinding in primary school. ## Signs of significant grinding — wear, jaw pain, headaches Parents should look for flattened, shortened, or shiny tooth surfaces — particularly on the back teeth — which indicate pathological wear. In young children with baby teeth some wear is normal, but accelerated or asymmetric wear is a reason to seek assessment. Jaw pain or clicking, morning headaches that resolve during the day, earache in the absence of infection, and reports of a sore or tired jaw are all worth reporting to a dentist or orthodontist. Sensitivity to temperature in otherwise healthy teeth can also be a sign of enamel loss from grinding. A dental examination can identify whether wear is within normal limits or has reached a threshold requiring intervention. ## Orthodontic considerations — does fixing bite issues help? The relationship between malocclusion and bruxism in children is debated. Some studies suggest that certain bite patterns — particularly posterior crossbites and significant overjet — may contribute to nocturnal grinding by preventing comfortable jaw rest. In these cases, orthodontic treatment addressing the underlying bite problem can coincide with a reduction in grinding, though it is rarely presented as a direct treatment for bruxism. Orthodontists who assess a grinding child will consider whether there is a bite component worth addressing, particularly if other treatment indicators are present. Parents should be cautious of any practitioner who claims orthodontic treatment will definitively cure bruxism — the evidence for this is not strong enough to support such claims. ## Night guards for children — are they appropriate? Custom night guards are sometimes prescribed for children with significant bruxism, particularly where permanent teeth are showing pathological wear. However, their use in children requires careful consideration. Growing jaws change rapidly, meaning a custom guard can become ill-fitting within months and potentially interfere with dental development if worn inappropriately. They are most commonly recommended in older children and adolescents with established permanent dentitions and documented wear, and only when made by a dental professional rather than purchased over the counter. For younger children, addressing underlying anxiety, improving sleep hygiene, and monitoring are usually preferred over appliance therapy. The decision should be made jointly with a dentist or paediatric dental specialist. ## Useful related pages [Bruxism and Orthodontics UK](https://virtualconsultant.online/guides/bruxism-teeth-grinding-orthodontics-uk) [Children's Orthodontics UK](https://virtualconsultant.online/guides/childrens-orthodontics-uk) [Nightguard vs Retainer UK](https://virtualconsultant.online/guides/nightguard-vs-retainer-uk) [Types of Braces UK](https://virtualconsultant.online/guides/types-of-braces-uk) [Get a Free Online Quote](https://virtualconsultant.online/evaluations/quote) This guide is for general information only.

In most cases, no — childhood bruxism is very common and usually resolves without treatment. You should seek assessment if the grinding is loud and frequent, if you can see visible flattening or wear on the teeth, if your child complains of jaw pain or morning headaches, or if the grinding is associated with snoring or disrupted sleep. Does bruxism go away in children? For the majority of children, yes. Bruxism that begins during the mixed dentition phase — when baby and adult teeth are coexisting — often resolves once the permanent teeth have fully erupted and the bite stabilises. Most children who grind in primary school do not continue grinding into adulthood. Can braces help stop teeth grinding in kids? In some cases, addressing an underlying bite problem through orthodontics coincides with a reduction in grinding — particularly where a posterior crossbite or significant malocclusion may be contributing to occlusal instability. However, braces are not a direct treatment for bruxism, and parents should not expect orthodontic treatment to eliminate grinding as a guaranteed outcome. When should I see an orthodontist about my child's grinding? If you can see visible wear on the permanent teeth, if your child complains of jaw pain or tenderness in the jaw muscles, or if your dentist has flagged the grinding as significant, an orthodontic assessment is reasonable. An orthodontist can identify whether there is a bite component contributing to the grinding and whether orthodontic intervention might be beneficial. Are night guards safe for children? Custom-made night guards can be appropriate for older children and teenagers with established permanent dentitions and documented tooth wear. They are not generally recommended for young children with baby or mixed teeth due to the risk of interfering with jaw development. Over-the-counter guards are not suitable for children and should be avoided. Any night guard for a child should be made by a dental professional and reviewed regularly. How do I know if grinding is damaging my child's teeth? The most reliable way is a dental examination. Signs to look for at home include teeth that appear shorter or more flattened than they used to be, shiny or smooth surfaces on the back teeth, and sensitivity to hot or cold in otherwise healthy teeth. A dentist can measure wear over time using study models or clinical photographs and advise whether intervention is needed. Explore your options Quick links Not sure where to start?
