An NTI splint is a small, custom dental device typically worn over the front teeth. It’s designed to reduce the intensity of clenching/grinding by changing how the teeth contact, which can help to reduce overload on the jaw muscles and TMJ system .
Who it may help:
- Night-time clenching/grinding (bruxism)
- Jaw muscle pain and tightness
- Tension-type headaches linked to jaw overload
- People who wake with a tight jaw or temple discomfort
What to expect:
- A dental fitting appointment (and follow-up review)
- Guidance on wear schedule and adaptation
- Ongoing monitoring to ensure it remains comfortable and effective
Important: Splints are not “one size fits all.” Your dentist will advise whether an NTI is appropriate for your symptoms, bite, and overall jaw presentation.
Some people benefit more from a full-coverage stabilisation splint (often worn at night) or other splint designs depending on:
- Joint vs muscle-dominant symptoms
- Tooth wear patterns
- Bite stability and comfort
- Clicking/locking patterns
- Previous dental work or sensitivity
If an NTI isn’t the best match, we’ll discuss other splint options and the reason for the recommendation.
What Results Can You Expect?
Splint therapy can help by:
- Reducing clenching/grinding load
- Supporting jaw muscle relaxation
- Protecting teeth from wear and damage
- Improving morning jaw tightness and tension headaches
Some people notice improvement quickly, while others may need a period of adjustment and follow-up, depending on how long symptoms have been present and what’s driving them.
