Bruxism is a condition characterized by the involuntary clenching or grinding of teeth, which can occur during sleep (nocturnal bruxism) or during the day (diurnal bruxism), often without the person being aware of it.
At the Marenco Dental Clinic in Bologna, it is evaluated as part of a functional analysis of the masticatory system, especially in the presence of associated symptoms or clinical signs.
It can be associated with stress, muscle tension, or functional habits and, over time, it can contribute to tooth wear, jaw fatigue, headaches and facial aesthetic changes.
It is therefore a functional condition that requires attention when symptoms or consequences begin to appear.
"Bruxism is managed through a personalised approach that addresses symptoms, muscle activity and contributing factors."
Bruxism is an activity of the masticatory muscles that leads to the clenching or grinding of teeth. The first signs may emerge over time or during a dental evaluation.
It is a functional condition of the masticatory system linked to the interaction between the neuromuscular system, sleep and individual factors.
There are two main forms:
It occurs during sleep and may be indicated by audible grinding or by symptoms upon waking up, such as jaw tension or muscle fatigue.
It is often associated with automatic neuromuscular microactivations during sleep.
It manifests itself as the unconscious clenching of teeth throughout the day, often during moments of concentration, stress or repetitive activities.
Bruxism does not have a single cause. It is the result of multiple factors that can interact with each other.
The main factors involved include:
▸ periods of stress and emotional tension
▸ states of anxiety or mental overload
▸ sleep disturbances
▸ unconscious clenching habits
▸ functional factors of the masticatory system
▸ individual predisposition
Especially in nocturnal forms, bruxism is often associated with automatic neuromuscular mechanisms that activate during sleep. This is not a voluntary behaviour, but rather involuntary episodes related to the physiological activity of the nervous system during different phases of sleep.
In many cases, these episodes occur in conjunction with physiological micro-arousals that cause the brief activation of the masticatory muscles, causing clenching or grinding.
Nocturnal bruxism is therefore the result of the interaction between neurological regulation of sleep, neuromuscular activity and individual predisposition.
Bruxism can manifest itself in different ways and with varying degrees of severity.
Continuous grinding can progressively wear away tooth enamel and increase sensitivity to cold or hot.
Many patients report stiffness or fatigue in their facial muscles, especially when waking up.
Many patients report stiffness or fatigue in the facial muscles, especially upon waking.
Neuromuscular tension and teeth clenching are often the body’s response to periods of high stress, conditions that can negatively affect jaw function and overall oral health.

Over time, the intense work of the masticatory muscles can contribute to greater jaw definition, in some cases associated with increased masseter muscle volume.
When bruxism persists, it can have progressive effects on teeth, muscles and joints.
The most common consequences include:
▸ Tooth wear
▸ Increased sensitivity
▸ Muscle fatigue
▸ Recurrent headaches
▸ Overloading of the jaw joint
▸ Possible masseter muscle hypertrophy
In some cases, these conditions overlap and also affect facial aesthetics.
Continuous clenching can lead to overloading of the masticatory muscles. When this occurs persistently, the masseter muscle can enlarge, altering the perception of the jawline.
This condition is often associated with a feeling of tension and fatigue in the jaw area.
When teeth clenching becomes persistent, the resulting muscle overload can also involve the masseter muscle, gradually contributing to a more pronounced jawline and a squarer facial appearance.
Learn more about bruxism and its relationship with masseter hypertrophy →The diagnosis of bruxism is based on a clinical assessment that takes into account:
▸ Dental wear
▸ Muscle tension
▸ Patient-reported symptoms
▸ Masticatory function
The goal is not only to identify the presence of bruxism, but also to understand its intensity and possible consequences for the oral system as a whole.
At the Marenco Dental Clinic in Bologna, the assessment is integrated into a comprehensive functional analysis.
The treatment of bruxism depends on the individual patient's clinical situation and the effects observed.
In some cases, a customized bite guard is used to reduce the load on the arches and protect the tooth surfaces.
Recognizing and correcting daily habits that lead to clenching, such as during moments of stress or concentration, can help reduce the frequency of episodes.
Every treatment plan must begin with a comprehensive evaluation, which allows for the definition of the most appropriate strategies for the masticatory function and the symptoms.
An early evaluation can help prevent worsening symptoms and identify the most appropriate treatment plan, with a better understanding the overall functional picture.
A bite guard protects teeth from wear but does not eliminate the causes of bruxism. Therefore, it is often integrated with other therapeutic approaches, based on a clinical evaluation and the patient's symptoms.
Stress is a common factor, but not the only one. Bruxism is multifactorial and can also involve the nervous system, sleep quality, individual predisposition and functional factors of the masticatory system.
Botulinum toxin (Botox) may be useful in selected cases to reduce the activity of the masticatory muscles and relieve pain and tension. It is not a cure for bruxism, but a supportive treatment in cases with a strong muscular component.
A clinical evaluation allows us to diagnose bruxism and assess its potential consequences for the masticatory system.
At the Marenco Dental Clinic in Bologna, we can perform a functional analysis and develop a personalised treatment plan.
