Jaw clicking: when should you get it checked?

A click when you yawn can make you wonder whether something is out of place, whether you grind your teeth, or whether you need braces. Start by noticing what happens alongside the sound.

TMJ is the joint. TMD describes a disorder.

You have a temporomandibular joint on each side of your jaw, near your ears. “TMD” is the term for disorders involving these joints and the muscles used to chew. A noise alone does not establish a diagnosis. The National Institute of Dental and Craniofacial Research explains the distinction.

When should I seek help?

Pay attention to pain, difficulty opening your mouth, or a jaw that catches or locks. Note whether chewing makes it worse and whether the symptoms interfere with meals or sleep. These details are more useful at an appointment than trying to reproduce the click again and again.

If you cannot eat or drink, seek urgent dental or medical care. Jaw locking, worsening pain, or limited opening also warrants prompt advice. The NHS patient guide to TMD describes symptoms that need assessment.

Will braces fix a clicking jaw?

Research does not support the idea that a bad bite or braces cause TMD. There is also insufficient evidence that orthodontically changing the bite treats TMD, and it can sometimes worsen symptoms. NIDCR recommends discussing simpler approaches before treatments that permanently change the teeth, bite, or joints.

You may have a separate reason to consider orthodontics. Ask for that reason to be explained clearly, along with what treatment can and cannot be expected to do for jaw symptoms.

What about grinding and nightguards?

Clenching and grinding, also called bruxism, can happen during sleep or while you are awake. They can be associated with worn or damaged teeth, sore muscles, and headaches. A dental examination can look for signs you may not notice yourself.

A guard may be recommended to protect teeth from grinding damage. NIDCR’s bruxism guidance explains that role. Relief of TMD pain is a separate question; evidence for guards treating that pain is limited. A guard is not a guaranteed way to stop every click.

If you already wear a retainer, tell the clinician before adding a guard. Our custom nightguard page explains how that discussion fits with orthodontic care.

What to bring to an assessment

A short note is enough: when the symptoms began, where you feel them, whether the jaw locks, and anything that seems to aggravate or ease them. Bring any guard or retainer you use and mention previous treatment or a recent injury.

At SC Orthodontics, Dr. Haykani evaluates the joint, muscles, tooth wear, and bite and coordinates with other providers when needed. Our TMJ and bruxism care page describes that approach. Ask which findings matter in your case, what the first step is, and when the plan should be reassessed.

While you arrange advice, softer foods and a break from gum chewing may reduce strain. Avoid forcing your jaw through painful movements. A dentist or clinician can help tailor comfort measures to your symptoms.

A few more questions

Does every painless click need treatment?

No. Painless joint sounds are common. Mention a new or changing symptom at a routine visit, and seek advice sooner if pain, locking, or restricted movement develops.

Does waking with a sore jaw prove I grind my teeth?

No. Grinding is one possibility, but a clinician should assess the symptoms and examine your teeth and jaw. Bring any observations from someone who hears you grinding at night.
