How to Stop Grinding Teeth in Sleep: Causes, Remedies & Treatment

You wake up with a sore jaw, a dull headache, and the vague sense that your teeth spent the night doing something they shouldn’t. Sleep bruxism affects millions, and this article explains the evidence-based causes — from stress to vitamin deficiencies — and what you can do about it.

Primary cause: Stress and anxiety (IAPD consensus recommendations) · Pediatric outlook: Often outgrown by adolescence (Sleep Foundation) · First-line treatment: Sleep hygiene and conservative care (PMC review)

Five key facts, one pattern: the evidence consistently points to a mix of neuromuscular, psychological, and sleep-related factors. Here’s a quick-reference table.

How do I stop grinding my teeth at night?

Natural remedies for sleep bruxism

1. Practice relaxation exercises and take a warm bath before bed to reduce nighttime clenching (Sleep Foundation).
2. Avoid caffeine and alcohol in the evening (PMC review).
3. Improve sleep hygiene — keep the room dark, quiet, and limit screen time before bed (Sleep Foundation).
4. Apply a warm compress to the jaw muscles to relieve tension (Sleep Foundation).

For children, the first step is always conservative: focus on sleep habits and stress reduction before reaching for a dental appliance (PMC review).

Nightguards and dental appliances

• Mouthguards prevent tooth damage but do not cure bruxism (IAPD).
• Occlusal splints are a common first-line dental intervention, especially for adults (IAPD).
• For children, the IAPD recommends individualized management that may include a splint, rapid palatal expansion, or no active treatment (IAPD).

The implication: lasting relief requires more than a mouthguard — it demands a comprehensive approach to the root causes.

When to see a doctor

• If you wake with persistent jaw pain, headaches, or worn-down teeth, consult a dentist or sleep specialist (Sleep Foundation).
• For children, a pediatrician should evaluate if grinding is accompanied by snoring, mouth breathing, or ADHD symptoms (PMC review: Bruxism in children with ADHD).
• Severe cases may require referral to a sleep clinic for polysomnography (Pediatric bruxism review).

Bottom line: Start with sleep hygiene and stress management. If damage is visible, add a nightguard. For children, monitor and treat conservatively — most outgrow it without intervention.

What vitamin are you lacking if you grind your teeth?

Magnesium deficiency and muscle tension

• Low magnesium is associated with increased muscle hyperexcitability, which may contribute to nocturnal clenching (PMC review).
• Some studies suggest magnesium supplementation can reduce bruxism symptoms, but the evidence is limited and conflicting (PMC review).

Calcium and vitamin D roles

• Vitamin D deficiency has been linked to muscle pain and bruxism, though the exact mechanism remains unclear (PMC review).
• Calcium works with magnesium for muscle relaxation; imbalances could theoretically worsen clenching (PMC review).

Vitamin B5 and stress connection

• Vitamin B5 (pantothenic acid) supports adrenal function and stress response, but direct evidence linking it to bruxism is absent (PMC review).
• Overall, the research on vitamin supplementation for bruxism is thin — most experts recommend a balanced diet over pills (Sleep Foundation).

Bottom line: Magnesium and vitamin D deficiencies are plausible contributors, but supplementation is not a proven cure. Get your levels checked before buying bottles.

Is teeth grinding an ADHD thing?

Prevalence of bruxism in ADHD children

• Studies show elevated bruxism rates in ADHD populations, with estimates ranging from 30-40% (PMC review: Bruxism in children with ADHD).
• Children with ADHD are more likely to experience sleep disorders, and bruxism often co-occurs with restless sleep (PMC review: Bruxism in children with ADHD).

Dopamine regulation and oral motor activity

• ADHD involves dysregulation of dopamine, which affects motor control and may contribute to involuntary oral movements (PMC review: Bruxism in children with ADHD).
• Stimulant medications used for ADHD can also increase the risk of bruxism as a side effect (PMC review: Bruxism in children with ADHD).

Distinguishing from stimming

• Stimming (self-stimulatory behavior) is intentional and repetitive, whereas sleep bruxism is unconscious and occurs during sleep (PMC review: Bruxism in children with ADHD).
• However, bruxism may serve a self-regulatory function for some individuals with ADHD, blurring the line (PMC review: Bruxism in children with ADHD).

What this means: a multidisciplinary approach — combining behavioural therapy, medication review, and dental care — is often necessary for children with ADHD who grind their teeth.

What does grinding teeth in sleep indicate?

Stress and anxiety as primary drivers

• Stress is the most common cause according to the IAPD and NHS (IAPD).
• Anxiety, depression, and psychosocial factors are frequently associated with childhood bruxism (Pediatric bruxism review).

Sleep disorders (apnea, snoring)

• Sleep apnea is a known comorbidity — breathing interruptions can trigger arousal and grinding (Pediatric bruxism review).
• Snoring and mouth breathing increase nocturnal muscle activity in children with bruxism (Pediatric bruxism review).

Medication side effects

• Certain antidepressants (SSRIs) and antipsychotics can induce or worsen bruxism (PMC review: Bruxism in children with ADHD).
• If grinding started after a new medication, discuss with your doctor before stopping the drug (IAPD).

Bottom line: Grinding is a signal, not a disease. It can point to stress, a sleep disorder, or a medication side effect. The underlying cause determines the treatment.

How to stop grinding teeth in sleep naturally and for different ages?

Home remedies for adults

• Relaxation exercises and warm baths help reduce nighttime clenching (Sleep Foundation).
• Avoiding caffeine and alcohol in the evening lowers the risk of grinding (PMC review).
• Jaw exercises and massages can relieve muscle tension before sleep (Sleep Foundation).

Approaches for toddlers and children

• Children often outgrow bruxism by adolescence, so treatment is usually conservative (Sleep Foundation).
• Focus on sleep hygiene: dark room, quiet environment, limit electronics before bed (Sleep Foundation).
• A nutritious diet low in added sugars supports sleep quality (Sleep Foundation).
• If grinding persists with pain or tooth wear, a pediatric dentist may recommend a simple occlusal splint (IAPD).

When natural methods are insufficient

• Severe cases require professional intervention — a dentist, sleep specialist, or therapist (Sleep Foundation).
• For children with ADHD, multidisciplinary care combining behavioural therapy, medication adjustments, and dental appliances may be needed (PMC review: Bruxism in children with ADHD).
• The IAPD emphasizes that pharmacological management in children is not supported by evidence (IAPD).

“Sleep bruxism is a sleep-related movement disorder that involves rhythmic or non-rhythmic masticatory muscle activity.”

— IAPD Consensus Recommendations (source)

“Conservative treatments based on diagnosis, management of sleep bruxism risk factors, and sleep hygiene appear to be the first-choice therapy in children and adolescents.”

— PMC Review (source)

For adults who grind their teeth, the choice is clear: invest in a nightguard to protect your teeth, but don’t stop there. Address the stress, review your medications, and get a sleep study if you snore. For children, patience and sleep hygiene usually win the day — most will outgrow it without any dental work.

Bottom line: Tailor the approach to the individual’s age and underlying causes. Adults need a comprehensive plan, while children often respond well to conservative care and time.
