Teeth grinding while asleep and the clenching of the jaws is known as sleep bruxism. Bruxism causes a range of both physical and dental issues. Now, researchers have looked to make a conclusion on the debate of whether or not sleep bruxism is associated with temporomandibular joint disorders – a cluster of conditions that cause a range of jaw issues. In conclusion, the researchers found a positive association.
When we sleep, we all hope for a calm rest to give our bodies a chance to recuperate. While many of us achieve this, a sizeable amount of the population do not.
One such issue that many face is the involuntary grinding of teeth while asleep. This is also associated with the clenching of the upper and lower jaw. These actions are part of a condition known as sleep bruxism.
There has been continued debate as to whether or not sleep bruxism is linked to Temporomandibular Joint Disorders (TJMs). These disorders cause intense jaw pain and can cause a range of dental problems.
Now, researchers have sought to understand the connection and find out whether or not sleep bruxism can be linked to TJMs.
What is Sleep Bruxism?
Sleep bruxism refers to when a person grinds their teeth while asleep. It usually includes the clenching of the jaws as well.
Statistics show that approximately 15% of the population suffer from sleep bruxism [1]. An even larger amount will have regular bruxism, which is tooth grinding during the day.
Teeth grinding can wear away tooth enamel due to the strong pressure on tooth surfaces. This makes teeth more vulnerable to decay and caries.
In fact, those with sleep bruxism typically have worse oral health in their lifetime [2]. Sleep bruxism also causes physical issues like jaw pain and even headaches.
Meanwhile, the Temporomandibular joint connects the jawbone to the skull. Any disorder that affects this region is considered to be a TMJ [3]. TMJs can cause jaw pain and muscle problems.
The Research
The intention of this research was to find out if there was indeed a connection between sleep bruxism and TMJs. The aim was to make a conclusion on what has proven to be a controversial subject [4].
The research was completed at the University Clinic of Dentistry at the Medical University of Vienna [5]. The findings were published in the Journal of Advanced Research [5].
The researchers entered the study with the theory that specific combinations of tooth shape and tooth location during grinding affects the mechanical load on the temporomandibular joint [5]. Therefore, sleep bruxism could be considered a risk factor for TMJs.
The study used a computer model of the masticatory region – an area that includes the bones and muscles of the head and neck. These models are used in cases where human experiments would be deemed highly unethical.
The researchers tested out various tooth movements and angles using the model [5]. The study analysed the effects of grinding on the first molar and a canine with different inclinations and angles used.
The researchers found that there was an association between bruxism and TMJs [5]. However, it was found that certain tooth shapes and locations were particularly associated with the development of TMJs [5].
What this means
The findings of the study show that there does seem to be a connection between bruxism and TMJs. This is especially pronounced in certain cases where teeth are at a certain angle or inclination during grinding.
Benedikt Sagl of the University of Vienna was among the researchers. Sagl commented on the findings [1]. Sagl suggested that “the decisive factor” was the “steepness” of grinding. For instance, “the flatter the tooth, the higher the risk of a TMJ disorder” [1].
Sagl suggested that more research will be needed to confirm their findings. It was suggested that further research will be used to “establish whether this finding can be incorporated into the development of therapeutic interventions for sleep bruxism” [1].
Thinking points…
1) Bruxism does affect many people. Sometimes, people will grind their teeth out of habit, which is very damaging! It is worth checking to see if you do suffer from bruxism. This is something that can be diagnosed by a dentist. Treatments typically include a mouth guard.
2) The research above is an example of how one seemingly-minor thing can have a big effect on our dental health. Therefore, it is very important that you take good care of your teeth! As part of this, it is vital that you visit the dentist for a regular check-up, where any problems can be identified. Consider booking an appointment now!
