Understanding Bruxism (Teeth Grinding)



Bruxism, commonly known as teeth grinding or clenching, affects millions of people worldwide. Despite its prevalence, many individuals are unaware of this condition and its potential impact on oral health. In this blog post, I will delve into the fundamentals of bruxism, explore its signs and symptoms, and discuss the importance of early detection and intervention.


What is Bruxism?

Bruxism refers to the involuntary grinding, clenching, or gnashing of teeth, often occurring during sleep. While occasional teeth grinding may not cause significant harm, chronic bruxism can lead to various dental issues and discomfort. Causes of Teeth Grinding

While the exact reasons behind teeth grinding, or bruxism, can sometimes remain elusive, several factors have been linked to this common condition:

  • Stress and Anxiety - one of the primary culprits behind teeth grinding is stress and anxiety. The pressures of daily life, work, relationships, or other sources of stress can manifest as teeth grinding during sleep or periods of heightened tension.

  • Sleep Problems - such as snoring and sleep apnea have also been associated with bruxism. Disrupted sleep patterns and breathing irregularities can contribute to involuntary grinding or clenching of teeth during the night.

  • Medications - including selective serotonin reuptake inhibitors (SSRIs) commonly used to treat depression and anxiety, have been linked to teeth grinding as a potential side effect. It's essential to consult with a healthcare professional if you suspect medication may be contributing to your bruxism.

  • Substance Use - including smoking, excessive alcohol consumption, and the use of stimulants like caffeine, ecstasy, and cocaine, can exacerbate teeth grinding. These substances may affect sleep quality and contribute to increased muscle tension, leading to bruxism.

  • Age- teeth grinding is also prevalent in children and teenagers, particularly during sleep. While the exact reasons for this phenomenon in younger individuals are not fully understood, it often resolves as they transition into adulthood and their permanent teeth emerge.


Signs and Symptoms:

Identifying the signs and symptoms of bruxism is crucial for early intervention. Common indicators include:

  • Tooth Wear: Excessive grinding can wear down tooth enamel, leading to flat or worn surfaces.

  • Jaw Pain: Persistent jaw pain or soreness, especially upon waking, may indicate bruxism.

  • Headaches: Frequent headaches, particularly in the temples or behind the eyes, can be associated with teeth grinding.

  • Facial Muscle Tension: Tense or tight facial muscles, especially upon waking, may result from clenching during sleep.

  • Sleep Disturbances: Bruxism can disrupt sleep patterns, leading to fatigue and daytime drowsiness.

Digital Intraoral Scans:

Modern advances in digital imaging allow dentists to use advanced digital intra-oral scans to assess the progression of tooth wear associated with bruxism. Advance digital software and allow us to monitor changes over time, enabling early intervention and personalised treatment plans.
