In today's fast-paced world, maintaining a balanced diet and ensuring optimal nutrition can be a challenge. While we're aware of how poor dietary choices can impact our overall health, few people understand the relationship between diet, nutrition and sleep disorders such as bruxism. Bruxism, commonly known as teeth grinding or clenching, is a prevalent sleep disorder affecting millions of people worldwide, impacting their oral health significantly.

Traditional treatments for bruxism, such as dental splints or mouthguards, provide temporary relief but may not address the root causes of the condition. Botox, an emerging treatment alternative, has gained traction in recent years for addressing bruxism symptoms by relaxing the jaw muscles responsible for grinding and clenching. However, it is crucial to explore other factors, including dietary and nutritional elements, that influence bruxism symptoms and understand how we can make changes to our diet to alleviate these symptoms.

Research in recent years has indicated a correlation between specific nutritional deficiencies and bruxism, suggesting that addressing these deficiencies may help reduce teeth grinding and clenching episodes. Additionally, specific foods or substances consumed in our daily diets can exacerbate bruxism symptoms by affecting our central nervous system, causing increased levels of arousal and stress.

In this comprehensive overview, we’ll delve into the world of vitamins, minerals, and other nutritional factors impacting bruxism. We will discuss common deficiencies linked to bruxism, foods that may worsen the condition, and strategies to make informed dietary choices to improve your oral and overall health. By understanding how diet and nutrition can influence bruxism, we believe you will be better equipped to take deliberate and meaningful steps toward managing this sleep disorder and achieving a more enjoyable and pain-free life.

Nutritional Deficiencies Linked to Bruxism

Research has suggested a possible connection between specific nutritional deficiencies and bruxism symptoms. Among these, deficiencies in magnesium, calcium, and certain B vitamins (particularly vitamin B5) have been observed in individuals suffering from bruxism. By restoring the levels of these essential nutrients in the body, you may experience a reduction in teeth grinding and clenching episodes.

Incorporating Foods Rich in Essential Nutrients

Ensuring a balanced diet rich in essential vitamins and minerals can help mitigate the potential impact of nutritional deficiencies on bruxism. Here are some great sources of the crucial nutrients mentioned above:

1. Magnesium: Found in nuts (such as almonds and cashews), seeds, whole grains, green leafy vegetables, and legumes. Magnesium can help relax your muscles and promote a better night's sleep.

2. Calcium: Abundant in dairy products, leafy greens, fish, and fortified foods, calcium plays a role in maintaining healthy teeth and muscles, and can help reduce bruxism symptoms.

3. Vitamin B5: Present in whole grains, legumes, avocados, and eggs, vitamin B5 (pantothenic acid) may help alleviate stress and anxiety, which are often associated with bruxism.

Incorporating these nutrient-dense foods into your daily diet can contribute significantly to enhancing your overall health and potentially reducing bruxism symptoms.

Foods and Substances Worsening Bruxism Symptoms

Certain foods and substances can exacerbate bruxism symptoms by increasing arousal and stress levels. Stimulants like caffeine and nicotine, for example, can make it more challenging to relax your jaw muscles, leading to increased grinding and clenching at night. Excessive consumption of alcohol can also negatively affect bruxism symptoms, as it can interfere with sleep quality and cause muscle relaxation followed by muscle hyperactivity.

Monitoring your intake of these substances and making conscious efforts to reduce their consumption can help alleviate bruxism symptoms in the long run.

Dietary Strategies to Reduce Stress and Anxiety

Stress and anxiety are significant factors contributing to bruxism, so adopting dietary habits focused on reducing these emotions can help manage the condition. Some excellent dietary strategies to reduce stress and anxiety include:

1. Incorporating Complex Carbohydrates: Whole grains, legumes, and starchy vegetables can help regulate blood sugar levels and promote the production of serotonin, a mood-enhancing neurotransmitter.

2. Consuming Omega-3 Fatty Acids: Fatty fish, walnuts, and flaxseed are high in omega-3s, known for their potential role in reducing inflammation and boosting brain function, which can help manage stress and anxiety.

3. Prioritising Foods Rich in Antioxidants: Berries, dark chocolate, and green tea are rich in antioxidants, which can help counteract the effects of stress and support brain health.

Incorporating these stress-reducing foods into your diet can help create a more relaxed state of mind, thus potentially lowering the likelihood of teeth grinding and clenching episodes.

The Role of Hydration and Oral Health

Ensuring adequate hydration is crucial for overall health and well-being, including oral health. Drinking sufficient water can help maintain healthy saliva production, which is essential for neutralising acid and protecting teeth from the wear and tear associated with bruxism. Aim for at least eight glasses of water a day, and consider reducing your intake of sugary and acidic beverages that could promote tooth erosion and exacerbate bruxism symptoms.


Understanding the impact of your dietary choices and nutritional factors on bruxism is essential for managing this sleep disorder effectively. By addressing nutritional deficiencies, incorporating nutrient-dense foods, reducing consumption of certain substances, focusing on stress-reducing dietary strategies, and maintaining proper hydration, you may notice improvements in your bruxism symptoms and overall health.
