Best Supplements for Grinding Teeth

By Maya

Grinding teeth, also known as bruxism, is a common condition that often happens during sleep or times of stress. It can lead to jaw pain, headaches, worn-down teeth, and poor sleep quality. While stress management, good sleep hygiene, and dental support (like mouthguards) are key approaches, natural supplements may also help by calming the nervous system and supporting muscle relaxation.

Here are two evidence-based supplements that may provide relief for people experiencing grinding teeth.

Magnesium

Magnesium is well known for its calming effects on both muscles and the nervous system. Since bruxism is often linked to tension and stress, magnesium can help reduce involuntary jaw clenching by promoting relaxation. Many people with bruxism benefit from supplementing magnesium in the evening to support restful sleep.

  • Mechanism of action: Promotes muscle relaxation, supports GABA (a calming neurotransmitter), and reduces nervous system overactivity.
  • Dosage or usage tip: Take 200–400 mg daily, ideally as magnesium glycinate or citrate, in the evening.

L-Theanine

L-Theanine is an amino acid found in green tea that promotes relaxation without causing drowsiness. It works by supporting neurotransmitter balance, helping to calm the mind and reduce stress-related jaw clenching. For individuals whose grinding is triggered by anxiety or nighttime tension, L-Theanine can be especially useful.

  • Mechanism of action: Enhances alpha brain wave activity, reduces stress, and supports neurotransmitter balance.
  • Dosage or usage tip: Start with 100–200 mg daily, taken in the evening or before stressful situations.

Summary

Grinding teeth can take a toll on both oral health and overall well-being. Magnesium helps relax muscles and calm the nervous system, while L-Theanine reduces stress and promotes mental relaxation. Together, these supplements may help lessen jaw clenching and improve sleep quality. Always consult a healthcare professional before starting new supplements, especially if bruxism is severe or persistent.
