Understanding Bruxism: Causes, Symptoms, and Treatment Options

Imagine waking up every morning with a dull headache and aching jaw, unsure of why you're experiencing this discomfort. You've tried different remedies, but nothing seems to provide lasting relief. The frustration builds as you endure yet another day of discomfort, wondering if there's a solution to this ongoing problem. If this sounds familiar, you may be one of the millions of individuals suffering from bruxism, a condition characterized by grinding and clenching of the teeth. 

Our objective in this article is to explore the mechanisms underlying bruxism and the risk factors associated with it. In addition, we will talk about the signs and symptoms of bruxism, which will help you determine if it is to blame for your discomfort.

What is Functional Dentistry?

Functional dentistry is a unique approach to dental care that focuses on finding the underlying causes of oral health issues, rather than just treating the symptoms. Unlike conventional dentistry, which mainly focuses on brushing, flossing, and visiting the dentist for cleanings, functional dentists take a holistic view of oral health and its connection to the rest of the body.

Functional dentists consider factors like the oral microbiome, gut health, inflammation, genetics, and hormones when diagnosing and treating oral health problems. They believe that oral health can impact overall health and vice versa, so they work closely with medical providers to ensure the best possible care.

Bruxism Causes

Bruxism, the nonfunctional movement of the jaw that includes clenching, grinding, clicking, and gnashing of teeth during sleep, can have multiple causes. While the exact pathophysiology of bruxism remains unknown, several factors have been identified as potential triggers.

One of the proposed causes of bruxism is neuromotor dysregulation, which suggests that the failure to inhibit jaw motor activity during sleep leads to bruxism episodes. This theory is supported by studies that have found increased non-REM microarousals in individuals with sleep disorders, indicating an irregular sleep structure in bruxers. 

Psychological factors, particularly stress and anxiety, have also been linked to the development of bruxism. Psychological stress is considered a risk factor for bruxism and can even predict temporomandibular pain. 

Studies have shown that individuals experiencing highly stressful lives are more likely to exhibit bruxism. Furthermore, there is evidence to suggest that daytime clenching can be significantly associated with experienced stress.

In terms of pharmacological factors, certain medications and substances have been implicated in the occurrence of bruxism. Long-term use of certain medications, such as selective serotonin reuptake inhibitors (SSRIs), has been associated with bruxism. 

Symptoms of Bruxism

While individuals may not be aware of their bruxism during sleep, they may experience certain after-effects upon waking up, such as a sore jaw, sore teeth, and even headaches. 

Clinical indicators of bruxism include attrition (tooth wear), bilaterally sore masseter and temporalis muscles, temporomandibular joint pain, and jaw locking upon waking. Some individuals may also experience otologic symptoms, such as ringing in the ear, blocked ear sensations, or even mild hearing impairment in association with bruxism.

It is important to note that many bruxers do not have substantial tooth attrition or make tooth-grinding sounds during sleep, making it challenging to determine its presence solely through examination or self-reporting. 

Functional Dentistry Techniques for Treating Bruxism

Functional dentistry offers several techniques for treating bruxism, aiming to address the underlying causes of this condition. Behavioral techniques are commonly employed in the treatment of bruxism, as they target the reduction of risk factors associated with this condition. 

Biofeedback therapy, for example, has been effective in inducing changes in parafunctional behaviors, although its ability to reduce bruxism is not strongly supported by evidence.

Occlusal appliances, such as splints or mouthguards, are another commonly used treatment modality for bruxism. These appliances are designed to protect the teeth from the damaging effects of bruxism by providing a well-adjusted and balanced contact pattern during sleep. 

Functional dentistry’s goal is to get to the root causes of stress so that patients can experience a reduction in bruxism symptoms. The goal of stress and anxiety therapy is to help patients identify and address the psychological factors that contribute to their bruxism. Stress can be reduced through techniques such as cognitive-behavioral therapy and relaxation exercises such as yoga and meditation. 

However, while occlusal appliances can protect the teeth, they may not necessarily stop bruxism entirely, and some patients may still experience associated symptoms like headaches and temporomandibular joint issues.  

Does Magnesium Help Bruxism?

When it comes to the role of magnesium in treating bruxism, there is some evidence to suggest its potential benefits. Magnesium, along with calcium, plays a crucial role in neuromuscular function, and deficiencies in magnesium and calcium have been implicated in the development of bruxism.

Studies have shown that replacing magnesium and calcium deficiencies may help in the treatment of sleep bruxism. It is believed that low levels of serum calcium could be involved in the development of bruxism. Furthermore, magnesium and calcium are necessary for regulating the nervous system and muscular function, including jaw muscle contraction.

While some studies suggest a potential relationship between magnesium deficiency and bruxism, more research is needed to establish a direct causal link and determine the effectiveness of magnesium supplementation.

Key Takeaways

• The condition of bruxism involves grinding or clenching the teeth. It can be caused by different things, like problems with how the brain controls jaw movements, stress, and certain medications. This can lead to tooth damage and other issues.

• It is common to wake up with headaches and a sore jaw when you suffer from bruxism. Functional dentists look for tooth wear and pain in the jaw joints when diagnosing bruxism. However, it's important to note that not everyone with bruxism will have obvious tooth damage or make grinding sounds during sleep, making it harder to diagnose.

• Treatment for bruxism can involve different approaches. Functional dentists may recommend using special mouthguards or splints to protect the teeth from damage. Additionally, behavioral techniques like biofeedback therapy can help reduce the risk factors associated with bruxism.
