                                            Did you know that oral parafunctional behaviour can contribute to pain, teeth wear and various temporomandibular disorders? π¦·
What is oral parafunctional behaviour?
Oral parafunctional behaviour refers to activities which involve unnecessary use of the mouth or jaw. Some common examples include:
β Grinding, bracing and/or clenching the jaw; this may be a conscious action (when you are stressed or anxious) or unconscious action (while you are asleep).
β Chewing gum or other objects like pens or clothing.
β Biting your nails, lips or cheeks.
β Pressing your tongue against your teeth or cheeks.
How does this affect my jaw function? π€
Most parafunctional behaviours result in excessive and unnecessary use of your masticatory muscles, the muscles that allow you to chew your food. When there is an overactivity of these muscles, often they can become uncoordinated and lose their ability to switch on and off appropriately; this may result in muscle asymmetries which can affect both your face shape and jaw function. π₯΄
These behaviours also place unnecessary load through the temporomandibular joint, which may contribute to symptoms of joint dysfunction like clicking or locking, pain in the TMJ, ears or face and/or restricted opening.
Our role as physiotherapists is to not only assess and treat jaw dysfunction, but to consider all the possible factors that may be contributing to your symptoms. Some of these may include:
-sleep hygiene
-stress and anxiety levels
-physical activity
-behavioural habits
-diet
By looking at the whole picture, we can help you to identify triggers and develop self-management strategies to prevent re occurrence. π
Here at Peak MSK Physio, we take pride in our excellent care provided to patients struggling with jaw pain. We work with patients to promote behavioural change and improve jaw pain and function and ultimately prevent the need for surgery. We also work closely with Dr Ankit Garg and Professor Michael Stubbs to implement effective rehab programs for patients pre and post surgery to prevent reoccurrence.
