Tempted to follow a jaw-stretching video before anyone has looked at the cause? From Georgetown, book an assessment first. We examine the restriction gently, consider why it has happened and explain whether exercises, dental care or referral fits.
Search for “jaw won’t open” and you’ll find plenty of stretching routines. Some are designed for people recovering from specific operations; others suit particular muscle problems. Used without knowing the cause, they can do little good or make things more uncomfortable. That’s why we suggest having the restriction looked at before you begin pushing it.
A limited opening is a sign rather than a diagnosis. It might come from tense chewing muscles, a jaw joint that catches, an infected or inflamed tooth, a recent bump to the face, or the after-effects of previous cancer treatment near the jaw. How it started, how fast it has changed and whether pain or swelling is present all point toward different kinds of care.
Coming in from Georgetown, you can expect a calm, unhurried visit. You won’t have to show how far you can force your jaw. Tell us where comfort stops, what has changed recently, and whether chewing, drinking or brushing has become a chore.
Share these observations when you call. If the restriction worsens suddenly or swelling develops, say so right away rather than leaving it for a routine visit.
Is there a sudden block, an even stiffness, or a limit that shifts from one attempt to the next? Has the jaw ever stuck open or shut, and for how long? Please don’t repeatedly push into a painful catch to demonstrate it.
Describe which daily tasks are affected and whether you’re keeping up with fluids and meals. Trouble drinking, or being unable to clean your teeth, calls for prompt advice. Real examples also help the dentist plan an exam within your range.
Recent dental treatment, a facial injury, swelling or earlier jaw issues all matter. So does any previous neck or facial surgery and radiation treatment. These change which questions need answering and whether another member of your care team should be involved.
If your jaw locks, opening suddenly becomes very limited, or eating and drinking aren’t possible, get urgent assessment. Fast-spreading swelling, swelling near the eye and any trouble breathing or swallowing need emergency medical care; call 911 for an immediate emergency.
The dentist may measure your opening, which helps document where you’re starting from. That measurement means little on its own. Ask how it connects to your history and the rest of the examination, and whether a probable cause has emerged. If something is still unclear, the plan should name what would help clarify it.
We also talk about keeping dental care workable in the meantime. Explain which positions or movements bring on difficulty, and agree a signal so you can stop at any point. If the full examination isn’t possible today, ask what has been safely assessed and how the remaining questions will be answered.

The clinician observes your jaw opening and listens to how you describe resistance or pain. Say when you reach a comfortable limit. Understanding how your jaw moves is the aim, not hitting a target or straining through significant discomfort.
The examination can include teeth, gums, chewing muscles and other relevant areas. Ask which findings support the explanation and whether more investigation is worthwhile. Treating every restriction as a joint problem may overlook something that needs different care.
Talk about what progress means for you, such as biting into an apple or brushing back teeth comfortably. Agree a review date and the changes that should bring you back sooner. Plans are easier to keep when their aims and limits are understood.
Describing your symptoms is enough; there is no need to repeat the most painful movement. If opening for an exam is difficult, mention it when you book so the appointment can be planned around it.
We ask whether the restriction arrived suddenly or gradually and whether it’s improving, worsening or fluctuating. Injuries, recent treatment, medicines and your medical background are reviewed. Records or contact details for another treating team can be helpful.
The dentist checks what your jaw does comfortably and examines related areas. Point to where you feel symptoms and say whether they’re typical. Breaks are fine, and any parts that couldn’t be examined should be noted rather than assumed normal.
You’ll hear what seems most likely and what is still uncertain. Imaging or referral is suggested only when it would answer a particular question. Ask what a test would change and whether medical, dental or specialist input should come before exercises or other management.
If a movement programme suits your diagnosis, ask for clear instructions on technique, frequency and when to stop. Confirm any other interim advice and how progress will be measured. Know whom to contact if symptoms worsen or the routine makes movement more painful.
Advice should come from your assessment, not a general routine. Exercises meant for recovery after a particular operation may be unsuitable for a new or unexplained restriction, even though both limit opening.
Avoid using objects, forceful stretches or repeated painful movements to work the jaw. If you’re prescribed a programme, keep to the technique, frequency and stopping rules you were given. If it increases symptoms, get in touch rather than doing more.
Note meaningful changes in eating, drinking, brushing and comfort, and when symptoms usually appear. A short record is helpful at review. Measuring every opening or deliberately setting off a lock isn’t needed; ordinary moments are more informative.
Let us know if you can’t clean an area or are struggling with food and fluids. The team can suggest adjustments or arrange more assessment. Please don’t postpone necessary care in the belief that your jaw must loosen first.

These answers help you prepare. A severe new restriction or difficulty keeping up with food and drink needs a call for prompt advice, not only an online request.
Arrange an assessment by calling our Bronte Street practice on (905) 876-4488. Mention sudden locking, swelling, a recent injury or trouble with meals and drinks, which helps the team judge how soon to see you and what comes next.
Causes, appropriate care, referral and recovery vary for each person. Online requests suit non-urgent enquiries and shouldn’t be used instead of urgent assessment if symptoms are severe or getting worse.
