10 Ways You Can Relieve Jaw Pain

Jaw pain can disrupt everything. Eating, talking, sleeping, concentrating — even yawning becomes uncomfortable when your jaw is sore, stiff, or throbbing. It is one of the most common reasons patients contact us for urgent advice.

The causes range from muscle tension and teeth grinding to wisdom tooth infections and dental trauma. Some jaw pain settles on its own within a day or two. Other cases signal an underlying problem that needs professional treatment.

The good news is that most jaw pain is manageable. Whether you need immediate relief at home or professional care from a same day emergency dentist London, there are clear, practical steps you can take right now.

This guide covers 10 effective ways to relieve jaw pain — and explains when it is time to seek emergency dental care London.

What Causes Jaw Pain?

Jaw pain is commonly caused by temporomandibular joint (TMJ) disorders, teeth grinding, wisdom tooth infections, dental abscesses, trauma to the face or jaw, and muscle tension from stress. Identifying the underlying cause is essential because the right treatment depends entirely on what is driving the pain.

The jaw joint — the temporomandibular joint — is one of the most complex joints in the body. It combines hinge and sliding movements, works constantly throughout the day, and is closely connected to the muscles of the face, head, and neck. When something disrupts its function, the discomfort can be significant.

Here are the most common causes:

• TMJ jaw pain. Dysfunction of the jaw joint itself — often from clenching, grinding, or joint inflammation — causes aching, clicking, and restricted movement.
• Wisdom tooth infection. Partially erupted wisdom teeth can trap bacteria under the gum, leading to swelling, pressure, and pain at the back of the jaw.
• Tooth infection. A dental abscess can cause deep, throbbing pain that radiates into the jaw, ear, and neck.
• Teeth grinding (bruxism). Clenching or grinding — often during sleep — overworks the jaw muscles and can cause chronic soreness, headaches, and tooth damage.
• Dental trauma. A blow to the face from a fall, accident, or sports injury can damage the jaw joint, fracture the jaw bone, or injure surrounding tissues.

Understanding the cause helps you choose the right relief method. For a deeper look at joint-related jaw problems, read our guide on jaw pain and TMJ disorders relief.

1. Apply a Warm Compress

A warm compress is one of the simplest and most effective ways to ease jaw pain caused by muscle tension or TMJ jaw pain.

How it works. Heat increases blood flow to the area, relaxes tight muscles, and reduces stiffness. It is particularly helpful when the jaw feels locked, achy, or fatigued after a long day — or first thing in the morning after night-time clenching.

How to apply. Soak a clean flannel in warm (not hot) water, wring it out, and hold it against the side of the jaw for 15 to 20 minutes. You can repeat this several times a day. A microwaveable heat pack also works well.

When to avoid. Do not apply heat if there is visible facial swelling, redness, or signs of infection. Heat can increase blood flow to an infected area and encourage the infection to spread. If swelling is present, use a cold compress instead (see step 2).

2. Use a Cold Compress for Swelling

When jaw pain is accompanied by swelling — from an infection, injury, or inflammation — a cold compress helps reduce the swelling and numb the discomfort.

How it works. Cold narrows the blood vessels, slowing blood flow to the area and reducing inflammation. It also has a mild numbing effect that provides short-term pain relief.

How to apply. Wrap ice or a bag of frozen peas in a thin cloth and hold it against the outside of the jaw for 10 to 15 minutes. Rest for at least 10 minutes before reapplying. Never place ice directly on the skin.

When to seek help. If the swelling is increasing, spreading to the cheek or under the jaw, or is accompanied by difficulty opening the mouth, this may indicate a dental infection jaw pain situation that needs urgent treatment. Visit our page on dental abscess treatment to learn what to expect.

3. Avoid Hard and Chewy Foods

What you eat matters when your jaw is sore. Hard, crunchy, and chewy foods force the jaw to work harder — and when the joint or muscles are already inflamed, this adds unnecessary strain.

Foods to avoid temporarily:

• Crusty bread, bagels, and baguettes
• Raw carrots, apples, and nuts
• Chewy sweets, toffee, and chewing gum
• Tough or large cuts of meat
• Foods that require wide mouth opening (tall burgers, large sandwiches)

What to eat instead. Stick to soft foods — scrambled eggs, soup, pasta, yoghurt, mashed potato, fish, and smoothies. Cut food into small pieces to minimise how wide you need to open your mouth.

Why it helps. Reducing the workload on the jaw gives the muscles and joint time to recover. This is particularly important for TMJ jaw pain, where repetitive strain worsens the condition over time.

4. Gentle Jaw Stretching Exercises

Gentle, controlled exercises can improve jaw mobility and reduce the muscle tension that contributes to TMJ jaw pain. They are especially useful for people who clench or grind their teeth.

Simple exercises to try:

• Relaxed jaw position. Rest the tip of your tongue on the roof of your mouth, behind the front teeth. Let the jaw relax and the teeth separate naturally. Hold for 30 seconds. Repeat throughout the day.
• Controlled opening. Place your tongue on the roof of your mouth and slowly open your jaw as wide as comfortable without pain. Hold for 5 seconds, close slowly. Repeat 5 times.
• Resisted opening. Place your thumb under your chin. Open your mouth slowly while applying gentle resistance with your thumb. This strengthens the muscles that control jaw movement.
• Side-to-side movement. Place a thin object (like a wooden lolly stick) between your front teeth. Slowly move your jaw from side to side. This encourages smooth lateral movement.

When to stop. If any exercise causes sharp pain, clicking that is painful, or locking of the jaw, stop immediately. These exercises are for mild tension and stiffness — not for acute injury or infection.

5. Address Teeth Grinding (Bruxism)

Teeth grinding is one of the most overlooked causes of jaw pain. Many people grind or clench at night without realising it. Over time, this puts enormous pressure on the jaw joint, the muscles, and the teeth themselves.

Signs you may be grinding:

• Jaw pain or stiffness when you wake up
• Headaches — particularly at the temples — in the morning
• Worn, flattened, or chipped teeth
• Tooth sensitivity that has developed gradually
• Your partner hearing grinding sounds at night

What helps. The most effective protection is a custom-fitted night guard (also called an occlusal splint) made by your dentist. It creates a barrier between the upper and lower teeth, reduces clenching force, and protects both the teeth and the joint. Over-the-counter guards offer some protection but are less comfortable and less precise.

Reducing triggers. Stress is a major driver of bruxism. Caffeine and alcohol in the evening can also increase clenching intensity. Being aware of daytime clenching — and consciously relaxing the jaw — helps break the habit over time. Grinding can also cause increased tooth sensitivity; learn more about sensitive teeth causes and cures.

6. Wisdom Tooth Pain Relief London

Jaw pain caused by wisdom teeth is one of the most common unexpected dental problems in adults aged 17 to 30 — though it can occur at any age. The pain is typically felt at the very back of the jaw and can be surprisingly intense.

Why wisdom teeth cause jaw pain:

• The tooth is partially erupted and the surrounding gum becomes inflamed (pericoronitis)
• The tooth is growing at an angle and pressing against the neighbouring tooth
• Food and bacteria are trapped under the gum flap, causing infection
• The eruption process itself creates pressure within the jaw bone

Immediate relief. Rinse with warm salt water several times a day. Take ibuprofen to reduce swelling and pain. Use a soft toothbrush to keep the area clean without irritating the swollen gum. Avoid poking the area with sharp objects.

When removal may be necessary. If wisdom tooth infections keep recurring, if the tooth is impacted, or if it is damaging the adjacent tooth, extraction is usually the recommended long-term solution. This can often be arranged as a same-day or next-day appointment.

7. Manage Tooth Infection Early

A tooth infection — particularly a dental abscess — can cause severe jaw pain that radiates well beyond the affected tooth. The pain is often deep, throbbing, and persistent. It can make the entire side of the jaw feel sore.

Signs of dental infection jaw pain:

• Intense, throbbing pain in the jaw that worsens over time
• Swelling of the gum, cheek, or area under the jaw
• A bad taste in the mouth or pus near the gum line
• Pain when biting down or touching the affected tooth
• Sensitivity to hot drinks that lingers

Why early action matters. A dental abscess will not clear up on its own. The infection needs to be drained and the source addressed — whether that involves root canal treatment, extraction, or another approach. Delaying treatment allows the infection to spread to surrounding tissues.

What to do now. Take ibuprofen for pain and inflammation. Rinse gently with warm salt water. Avoid applying heat to the face. Arrange an urgent dental appointment as soon as possible. Recognise the signs early — read about the 5 warning signs of tooth infection spreading.

8. Over-the-Counter Pain Relief (Short-Term Only)

Over-the-counter painkillers can provide useful temporary relief while you arrange professional care. They are not a long-term solution — but they can make the wait more manageable.

What works best for jaw pain:

• Ibuprofen is usually the most effective option because it reduces both pain and inflammation. Take as directed on the packaging.
• Paracetamol can be taken alongside ibuprofen (at different times) for additional pain relief if needed.
• Topical gels containing benzocaine can numb a specific area of the gum temporarily.

Important reminders. Do not exceed the recommended dose. Do not place aspirin directly on the gum — this can burn the tissue. Pain relief masks symptoms but does not treat the cause. If you need painkillers for more than two days, the underlying problem needs professional assessment.

If pain is severe and not responding to over-the-counter medication, you may need urgent care. Read our guide on severe toothache relief for more on what to expect during an emergency appointment.

9. Seek Same Day Emergency Dentist London If Pain Worsens

If your jaw pain is getting worse rather than better, it is time to see a professional. Some jaw problems resolve with home care. Others need prompt clinical assessment to prevent them from becoming more serious.

See a same day emergency dentist London if you experience:

• Pain that has been persistent for more than 48 hours
• Jaw locking — unable to open or close fully
• Swelling that is increasing or spreading
• Difficulty eating, drinking, or swallowing
• Fever or feeling generally unwell alongside jaw pain
• Numbness or tingling in the lip, chin, or tongue

What happens at an emergency appointment. The dentist will examine the jaw, assess the teeth, take X-rays if needed, and identify the cause. Treatment may begin on the same day — whether that involves draining an abscess, stabilising a tooth, prescribing medication, or fitting a splint.

You do not need to be a registered patient to be seen urgently. Our walk-in dentist in London service accepts patients without prior registration. You can also book an urgent dental appointment online to secure a specific time.

10. Don't Ignore Persistent Jaw Pain

It is tempting to wait and hope jaw pain will go away on its own. Sometimes it does. But persistent jaw pain — especially pain that has lasted more than a week, keeps coming back, or is getting progressively worse — usually indicates an underlying issue that needs attention.

What persistent jaw pain could mean:

• A developing TMJ disorder that will worsen without management
• A cracked or fractured tooth that is not yet visible on the surface
• A slow-growing infection at the root of a tooth
• Unresolved dental trauma from a previous injury
• Bruxism-related damage to the teeth and joint

Why early diagnosis matters. The earlier a problem is identified, the simpler and less invasive the treatment tends to be. A small crack can be bonded. An early infection can be treated conservatively. A TMJ issue can be managed with a splint and exercises. Waiting often means the problem becomes more complex and the treatment more involved.

If you have experienced recent trauma to the face or jaw, even if symptoms seem mild, it is worth having an assessment. Read about dental trauma emergency treatment to understand what to look out for.

When Jaw Pain Is a Dental Emergency

Most jaw pain responds to home care and resolves within a few days. But certain signs indicate that the pain is linked to a condition that requires urgent professional treatment.

Treat jaw pain as a dental emergency if:

• Swelling is visible and increasing — especially if it is spreading to the cheek, under the jaw, or towards the eye or neck
• You have a fever alongside jaw or dental pain — this suggests active infection
• You cannot open your mouth more than a finger's width — this may indicate a spreading infection or joint problem
• There is pus, a foul taste, or discharge — signs of an abscess that needs drainage
• Pain is severe and unresponsive to ibuprofen and paracetamol combined
• You have experienced trauma to the face and suspect a fracture or displaced tooth

In these situations, prompt assessment and treatment can prevent the problem from escalating. At Emergency Dentist London clinic, we see jaw pain emergencies every day. Same-day appointments are available, and no referral is needed.
