TMJ Splints for Jaw Pain,
Headaches and Teeth Grinding
Bespoke TMJ splints designed with precision and care, in a relaxing central London clinic.
Thoughtful Support For Jaw Tension, Headaches And Teeth Grinding
Jaw discomfort can be surprisingly intrusive. For some people it shows up as a tight feeling around the face or temples. For others, it is headaches that seem to start behind the ears, or a jaw that clicks, aches or feels tired by the end of the day. Often, these symptoms build gradually, which makes them easy to dismiss at first.
At Square Mile Dental Centre, we regularly see patients affected by temporomandibular joint concerns, commonly known as TMJ or TMJD. While symptoms are mild for some, others experience ongoing discomfort that affects sleep, focus and everyday routines. When that happens, a bespoke TMJ splint can play an important role in restoring comfort and balance.
What is a TMJ Splint?
A TMJ splint, sometimes called a TMJ mouthguard or jaw splint, is a removable dental appliance designed to support the jaw and reduce strain on the joints and muscles.
Splints are made from a firm yet comfortable acrylic material and are designed to fit neatly over either the upper or lower teeth. They are transparent and discreet, and most people wear them at night, although daytime wear may be advised in certain cases.
Unlike shop-bought mouthguards, a splint from Square Mile Dental Centre is made specifically for your bite. This accuracy matters. A well-designed splint helps guide the jaw into a more relaxed position and distributes pressure more evenly across the teeth.

Your Assessment and Splint Planning
At Square Mile Dental Centre, splint therapy always begins with a clear conversation. We take time to understand your symptoms, how they affect you, and what you hope to achieve.
Your assessment may include:
- A detailed review of jaw movement and bite
- Discussion of habits such as clenching or grinding
- Digital scans of your teeth
Digital scanning allows us to capture your bite accurately and comfortably, without traditional impressions. This supports precise splint design and helps ensure a secure, comfortable fit.
Your splint is then made to measure and fitted carefully. Adjustments are made as needed so it works effectively and feels natural to wear.
Most patients require two appointments, and there is no downtime following fitting.

How can a Splint help?
Many TMJ symptoms are driven by unconscious habits, particularly clenching or grinding. Over time, this places repeated pressure on the jaw joints and muscles.
A bespoke TMJ splint can help by:
Reducing pressure on the jaw joints
Allowing overworked jaw muscles to relax
Limiting the effects of clenching and grinding
Protecting teeth from wear and sensitivity
For many patients, this leads to fewer headaches, less facial tension and improved comfort on waking. It can also support better sleep by reducing nighttime jaw activity.

What is the Temporomandibular Joint?
The temporomandibular joints sit just in front of your ears and allow your jaw to move smoothly when you speak, chew or yawn. These joints work closely with the surrounding muscles, teeth and bite. When that system is under strain, symptoms can develop.
01
TMJ concerns are often linked to:
● Jaw clenching or teeth grinding, especially during sleep

02

● Jaw pain or stiffness

What Does Wearing a Splint Feel Like?

Is a Splint a Long-term Solution?
Splints are removable and do not permanently alter your teeth or bite. Many patients find that regular use provides consistent relief, particularly when combined with good habits and ongoing dental care.
Splints can be replaced if they become worn or damaged, and periodic reviews help ensure they remain effective as your bite or jaw function changes over time.
For many people, a splint offers a practical and measured way to manage TMJ symptoms without invasive treatment.
Taking the Next Step
If jaw pain, headaches or teeth grinding are affecting your daily life, a bespoke TMJ splint may help restore comfort and balance. A professional assessment will determine whether splint therapy is suitable for you and how it can be integrated into your care.
Our team is always happy to talk things through and answer your questions.

Frequently Asked Questions
How long does it take to notice improvement with a TMJ splint?
Some people notice reduced jaw tension or fewer headaches within days, while others may need several weeks of consistent wear before symptoms ease.
Can a TMJ splint make my jaw pain worse at first?
Mild temporary changes or muscle awareness can occur during the adjustment period, but worsening pain should be reviewed promptly so the splint can be adjusted.
Will wearing a TMJ splint change my bite permanently?
No. A professionally made TMJ splint is removable and does not permanently alter your bite when used as directed and reviewed appropriately.
Can I talk or drink water while wearing a splint?
Yes. Talking and drinking water are usually fine, although eating is not recommended unless specifically advised by your dentist.
Is a TMJ splint the same as a sports mouthguard or night guard?
No. TMJ splints are designed to guide jaw position and muscle activity, whereas sports or shop-bought guards mainly protect teeth from impact or wear.
Can I wear a TMJ splint if I have crowns, implants or veneers?
In most cases, yes. Your dentist will assess your existing dental work and design the splint to fit safely and comfortably around it.
What happens if my splint cracks or no longer fits properly?
A damaged or ill-fitting splint should not be worn. It can usually be adjusted or replaced after assessment to ensure it continues to support your jaw correctly.
Do TMJ splints help with stress-related clenching during the day?
They can help protect your jaw and teeth, but managing daytime clenching often works best alongside stress awareness and habit-focused guidance from your dentist.
