TMJ Dentist Insight: How Different Bite Types Can Lead to TMJ


According to the National Institute of Health, up to ten percent of people suffer from severe TMJ that requires treatment. While there are a variety of dental issues that cause TMJ, some of the most common are those that originate from your bite. This includes problems with overbite, underbite, or crossbite. If you are experiencing discomfort from TMJ, the TMJ dentist specialists at Cobb Center for Advanced Dentistry will utilize their award-winning services to provide you with exceptional care that is free of pain.

To understand how issues with your bite cause TMJ, it is important to know more about its symptoms.

TMJ Dentist: What is TMJ?

Also known as TMD (Temporomandibular Disorder), TMJ is a type of dental disorder that affects how joints and facial muscles connect to the lower jaw of the skull. If there are tensions in these muscles, it negatively impacts the way you move your jaw joints or how the upper and lower teeth fit together. This leads to symptoms including pain of the neck, head and jaw, reduced oral mobility, difficulty chewing and a popping or clicking of the jaw.

According to TMJ dentists, some of the most common issues related to TMJ stem from your bite.

Overbite and its Relationship to TMJ

An overbite occurs when your front upper teeth overextend past your front bottom teeth. This is caused when the upper dental arch is too short or narrow for the lower dental arch to lay properly. As a result, the lower jaw tends to sit further back from its natural position in the mouth to accommodate the fit.

When there is not enough room for the jaw to experience its normal fit due to overbite, the teeth can crowd or grow in crooked, leading to increased pressure in the mouth. This undue stress causes TMJ. Overbites also create compression in the jaw joint and tension in the facial muscles, producing further misalignment that also leads to TMJ.

How Underbites Can Generate TMJ

When you have an underbite, your lower jaw extends past the upper jaw, which causes the bottom front teeth to jut further out from the upper front teeth. This is problematic because the upper front teeth are supposed to lay slightly over the bottom front teeth.

This protrusion of the lower jaw places strain on the jaws and facial muscles, which generates TMJ. It also makes it more difficult for you to chew food, which can wear down your tooth enamel or break your teeth. When left untreated, these problems also cause TMJ.

TMJ Dentist: Crossbite and Its Contributions to TMJ

Crossbite happens when there is a misalignment between the upper and lower teeth. This usually originates from the premature growth of your permanent teeth before the loss of your baby teeth. In these instances, the permanent teeth are unable to grow in properly due to the presence of the baby teeth, which causes misalignment.

When this misalignment is present, you unknowingly put undue stress and tension on your jaw and grind your teeth, leading to TMJ. In severe cases, this misalignment can affect the way your jaw and facial structure grows, causing chronic TMJ.
