What’s the Difference – TMJ Splints vs Night Guards

Although the terms night guard and temporomandibular joint (TMJ) splint are often interchangeable, and are effective in protecting the jaw joints, muscles, and teeth, they serve different purposes. These two dental devices are made to meet the different needs of patients suffering from TMJ issues. 

If you’re experiencing pain in your TMJ, your Fairview dentists will help you understand if a TMJ splint or night guard will help, and why your dentist would prefer one treatment over the other.

WHAT IS THE DIFFERENCE BETWEEN A SPLINT AND A NIGHT GUARD?

The term TMJ splint and night guard are typically used interchangeably, however, they treat different types of TMD symptoms. A splint has many names, such as dental splint, occlusal splint, bite splint, bite guard, occlusal appliance, and dental appliance. The biggest difference between a TMJ Splint and a night guard is a night guard is a type of splint and not all splints are night guards.

What is a Splint?

There are many types of splints to treat TMD, each designed specifically to help relieve jaw pain. They come in two styles, permissive and nonpermissive. A permissive type splint allows the teeth to move freely over the biting surface, and a nonpermissive type splint uses ramps or indentations to restrict movement over the biting surface. In general, both types have the same goal – to stabilize and support the joints and muscles to prevent malocclusion, or the incorrect positing of the teeth when the jaws are closed.

With TMJ splints, they provide more vertical support than night guards, and should move the lower jaw, guiding it to a more natural comfortable position. The length of time for patients suffering from TMD is recommended to wear the TMJ splint from a few weeks or months, depending on the severity of their symptoms.

What is a night guard?

A night guard, also known as an occlusal guard, is an excellent option for people who suffer from bruxism. Bruxism is a condition that causes chronic clenching or grinding of the teeth. Over time, this can lead to tooth wear and fractures, as well as myofascial pain, headaches, and other painful issues. Using these guards does not eliminate all symptoms, but it will help protect your teeth from further damage when you sleep. Besides protecting your teeth from bruxism, just like TMJ Splints, night guards are designed to provide movement of the lower jaw, but they do not always provide the best forward and vertical support people with jaw problems.

While it may cost less by buying a night guard over-the counter, the cost for a custom night guard is well worth it in the long run. When you get a night guard from your general dentist, the night guard will have your teeth’s impression on it, making a comfortable snug fit, and most of all, protection against bruxism.

Types of TMJ Splints to Treat TMD

Individuals with TMD can now find relief from symptoms by wearing a splint that is designed specifically for their condition. Splints for TMD come in many shapes and sizes, but they all perform a similar function. They allow your jaw muscles to relax while dispersing pressure across the teeth evenly, so it’s not focused on one spot or joint. By preventing the pressure to focus on one spot or joint, it helps to reposition your jaw into the proper alignment.

Silicone – Silicone occlusal splints are a myofascial pain dysfunction treatment that can ease the discomfort of tight muscles in your face.

Permissive splints – Permissive splint, also known as stabilization splints, are made from acrylic resin and are worn at night while sleeping. They provide support for your jaw joints so that when you move them during your sleep, it does not cause pain. This type of splint is the most common use of this splint to treating TMJ Issues.

Non-permissive – A non-permissive splint is designed with ramps or indentations that limit the movement of the jaw.

Soft Night Guard – A soft night guard for teeth grinding is a must-have for those who are prone to suffer from bruxism while they sleep. With the help of this soft rubber material that sits between your teeth, you’ll be able to reduce many symptoms associated with bruxism such as tooth sensitivity or headaches, in addition to experiencing less discomfort from morning jaw pain. This type of night guard is typically recommended for people with milder cases of teeth clenching or teeth grinding.

Hybrid Night Guard – A hybrid night guard is a new design that features a soft rubber interior paired with a hard acrylic exterior. This design offers both comfort and strength, giving you peace of mind throughout the evening to prevent and protect yourself from grinding your teeth at night. Your dentist near you may suggest a hybrid night guard if you’re a moderate to heavy teeth grinder.

Hard Night Guard – A hard night guard is the best option for heavy grinders because of its durability and strength. It’s constructed with durable acrylic material, providing extra protection for those who severely suffer from teeth grinding at night.

Reasons for Occlusal Splints

A dentist may recommend an occlusal splint for a variety of reasons, especially if you experience tooth grinding, clenching, or early TMJ pain. Getting a night guard for TMJ, or a occlusal splint is an efficient, low-cost way to remedy the movement that’s causing pain, helps your jaw and facial muscles to relax, and to prevent it from getting worse. Patients typically get a splint if they suffer from:

  • Temporomandibular joint (TMJ) disorder
  • Bruxism
  • Sleep apnea
  • Headaches or jaw joint inflammation
