Types of Dental Pain: What Your Toothache Is Telling You (2026 Guide)

Last updated: March 2026. This guide covers the different types of dental pain, what each type may indicate, how urgent each one is, and when to seek emergency care. All information is sourced from the NHS, NHS England, the Oral Health Foundation, and other official UK health organisations.

Not all toothaches are the same. A sharp sting when you drink cold water is telling you something very different from a deep, throbbing ache that keeps you awake at night.

Understanding the type of pain you are experiencing is the single most useful thing you can do before calling your dentist or NHS 111. It helps you judge how urgently you need care, gives your dentist vital diagnostic clues, and can prevent you from either panicking over something minor or ignoring something serious.

This guide walks through the most common types of dental pain, explains what each one typically means, and tells you exactly when to seek help.

At a Glance: Types of Dental Pain and What They Mean

Sharp Tooth Pain -- Causes and What It Means

A sharp, sudden stab of pain -- often triggered by eating, drinking something hot or cold, or biting into food -- is one of the most common reasons people call their dentist.

What typically causes it:

• Tooth decay (dental caries). The NHS describes "a sharp pain in your tooth when eating or drinking hot, cold or sweet things" as a hallmark symptom of tooth decay. As a cavity deepens, it gets closer to the nerve, making pain more intense and frequent.

• A cracked or damaged tooth. The Oral Health Foundation identifies sharp pain alongside "sensitivity to hot or cold" as primary warning signs of a cracked tooth.

• A loose or broken filling. When an old filling becomes damaged, it can expose the tooth structure underneath, causing sharp sensitivity.

"Toothache can start suddenly. It can cause pain and discomfort that ranges from mild to very severe. The pain may affect not only your tooth, but also your head, ear and jaw." -- NHS, Toothache

How urgent is it? If the pain is brief and manageable with over-the-counter painkillers, book a dental appointment within a few days. If it is severe, constant, or not helped by painkillers, contact NHS 111 for urgent advice.

Throbbing Tooth Pain -- Why It Happens

Throbbing pain is the one that keeps you awake. It feels like a rhythmic, pounding sensation that may come in waves and is often worse when you lie down, because more blood flows to your head.

What typically causes it:

• A dental abscess. The NHS defines an abscess as "a build-up of pus in the teeth or gums caused by an infection." Throbbing pain is its hallmark symptom, often accompanied by swelling, a bad taste in the mouth, and redness.

• Acute pulpitis. When the soft tissue inside your tooth (the pulp) becomes severely inflamed -- usually from deep decay or trauma -- it produces an intense, throbbing ache.

• Spreading infection. If an abscess is left untreated, the infection can spread, causing swelling in the face or jaw.

"A dental abscess will not go away on its own. See a dentist as soon as possible." -- NHS, Dental Abscess

How urgent is it? Throbbing dental pain is always urgent. Contact NHS 111 or an emergency dentist. A suspected abscess needs same-day or next-day assessment. If swelling extends to your eye or neck, or you have difficulty breathing or swallowing, call 999 or go to A&E immediately.

Dull, Constant Ache in Your Tooth or Jaw

A low-level, grinding ache that does not go away is easy to dismiss -- but it usually means something needs attention. This type of pain can be difficult to pinpoint to one specific tooth.

What typically causes it:

• Bruxism (teeth grinding). The NHS states that teeth grinding causes "face, neck and shoulder pain" and "a painful jaw, which can lead to a condition called temporomandibular disorder (TMD)." Pain is typically worse on waking if you grind at night, or after periods of stress.

• Impacted wisdom teeth. Wisdom teeth that do not have room to emerge properly can cause a persistent dull ache in the back of the jaw, along with swelling and difficulty opening the mouth.

• Gum disease. Advanced gum disease produces a "painful and swollen" sensation in the gums that can feel like a deep, diffuse ache rather than a sharp tooth pain.

• Sinus-related pain. Sinus infections can produce a dull ache in the upper back teeth, because the roots of upper molars sit very close to the maxillary sinuses. This is often bilateral (both sides) and may worsen when bending forward.

How urgent is it? A persistent dull ache lasting more than two days warrants a dental appointment. The NHS advises seeing a dentist if toothache "lasts more than 2 days."

Pain When Biting Down or Chewing

If pain only appears when you place pressure on a tooth -- biting into food, chewing, or clenching -- the cause is usually mechanical rather than infection-related.

What typically causes it:

• Cracked tooth syndrome. The Oral Health Foundation describes "pain when biting or chewing" as a primary warning sign. A distinctive feature of a cracked tooth is pain on the release of biting pressure -- a brief, sharp stab when you stop biting down.

• A high or poorly adjusted filling. If a filling sits slightly too high, the tooth absorbs more pressure than it should, causing pain every time you bite.

• Periodontal problems. Infection or inflammation in the periodontal ligament (the tissue holding your tooth in its socket) makes the tooth tender under pressure.

• A dental abscess. The NHS notes "difficulty opening your mouth and chewing" as a symptom of a dental abscess.

How urgent is it? If the pain is manageable, book an appointment within a few days. If it is accompanied by swelling, a bad taste, or fever, treat it as urgent and contact NHS 111.

Shooting or Electric Pain in a Tooth

This is a sudden, intense bolt of pain that can feel like an electric shock. It may be brief (lasting seconds) or may come in repeated bursts. Sometimes it radiates along the jaw or up towards the temple.

What typically causes it:

• Nerve involvement. When decay or damage reaches the nerve inside a tooth, it can produce sudden, shooting sensations. This is a sign of irreversible pulpitis -- meaning the nerve is too damaged to recover and will likely need root canal treatment or extraction.

• Trigeminal neuralgia. In rare cases, shooting pain in the face and jaw is caused by trigeminal neuralgia, a condition affecting the trigeminal nerve. This is a medical condition rather than a dental one, but is often first investigated by a dentist.

Signs your tooth pain involves the nerve:

• Pain lingers for more than 30 seconds after removing the trigger
• Spontaneous pain that occurs without any stimulus
• Pain that radiates to your ear, jaw, or temple
• Sensitivity to both hot and cold (not just one)
• Pain that wakes you up at night

How urgent is it? Nerve-related dental pain should be assessed urgently. Contact your dentist or NHS 111 within 24 hours.

Tooth Pain That Comes and Goes

Intermittent pain -- appearing one day, vanishing the next, then returning unpredictably -- is frustrating precisely because it is easy to dismiss. But it is often an early warning sign.

What typically causes it:

• Early-stage tooth decay. The NHS notes that "tooth decay may not cause any symptoms at first" but will eventually trigger pain with temperature or sweetness, often inconsistently before becoming constant.

• Cracked tooth syndrome. The Oral Health Foundation lists "pain that comes and goes" as a key symptom. The crack opens under biting pressure and closes when released, causing pain that is difficult to reproduce reliably.

• Reversible pulpitis. When inflammation of the tooth pulp is still mild, it produces episodes of pain that come and go. At this stage, treatment (usually a filling) can save the tooth and prevent more complex procedures later.

How urgent is it? Not immediately dangerous, but do not wait for it to become constant. Book a dental appointment within one to two weeks. Early treatment at this stage is simpler, less invasive, and less expensive than waiting until the pain becomes severe.

Lingering Pain After Hot or Cold Drinks

Brief sensitivity to hot or cold that fades within a few seconds is common and usually not serious -- it often indicates enamel wear or mild gum recession.

But when pain lingers for 30 seconds or more after you remove the hot or cold stimulus, it tells a different story.

What the duration of sensitivity means:

• Fades within seconds: Likely enamel erosion, gum recession, or a recent filling. Usually manageable with desensitising toothpaste.
• Lingers for 30+ seconds: Likely irreversible pulpitis -- the nerve is inflamed beyond recovery and will need root canal treatment or extraction.
• Sensitivity to heat (not just cold): A particularly important warning sign. When a tooth that was previously only cold-sensitive starts reacting to hot drinks, it often means the condition is progressing.

Reversible pulpitis shows "sensitivity to cold or sweet food and drinks but rarely to hot ones." When sensitivity to heat develops, it often signals progression toward irreversible pulpitis. -- Patient.info, Toothache

How urgent is it? Brief cold sensitivity is routine -- mention it at your next check-up. Lingering sensitivity or heat sensitivity should be assessed within one to two days.

Radiating Pain to the Jaw, Ear, or Head

When dental pain does not stay in one tooth but spreads to the jaw joint, ear, temple, or side of the head, it can be confusing. Some patients visit their GP for an earache that turns out to be dental, or treat headaches for weeks before discovering a tooth problem.

What typically causes it:

• Temporomandibular disorder (TMD). The NHS states that TMD causes "pain around your jaw, ear and temple" and "a headache around your temples." It is closely linked to stress, jaw clenching, and teeth grinding.

• Dental abscess with spreading infection. Abscess pain can radiate along the jaw and to the ear as infection spreads.

• Bruxism. The NHS states that teeth grinding causes "face, neck and shoulder pain" and earache through referred pain from the jaw muscles.

• Impacted wisdom teeth. Lower wisdom teeth sit close to the inferior alveolar nerve; impaction can cause pain that radiates along the jaw or into the ear.

How urgent is it? Chronic TMD-related pain without swelling or infection signs warrants a routine dental appointment. If there is spreading swelling, fever, or any infection signs, contact NHS 111. If pain is accompanied by difficulty breathing, swallowing, or changes in vision, call 999 or go to A&E.

How to Tell If Your Tooth Pain Is Serious

Most dental pain, while uncomfortable, is not dangerous. But some symptoms indicate that something more serious is happening and that you need care quickly.

Warning signs that require emergency care (call 999 or go to A&E):

• Swelling around your eye or spreading down your neck
• Difficulty breathing, swallowing, or speaking due to swelling
• Uncontrolled bleeding from the mouth
• A swollen or painful eye, or sudden changes in your vision

"Go to A&E if you have toothache and: the area around your eye or your neck is swollen, swelling in your mouth or neck is making it difficult for you to breathe, swallow or speak." -- NHS, Toothache

Warning signs that require urgent care (call NHS 111):

• Severe pain that is not controlled by paracetamol or ibuprofen
• Pain that is affecting your sleep or daily activities
• Facial swelling that is getting larger
• Fever (high temperature) alongside dental pain
• A swelling, lump, or patch inside your mouth that is growing

Signs you should book a dental appointment soon:

• Pain lasting more than two days
• A bad taste in your mouth
• Red or swollen gums alongside tooth pain
• Pain when biting that is getting worse

How to Describe Your Pain to a Dentist

When you phone your dentist or call NHS 111, the more clearly you can describe your pain, the better they can help you. Dental triage teams use a framework called SOCRATES to assess pain. You can use the same approach:

This framework comes from NHS England's clinical guidance for dental triage. Writing down your answers before you call can help you get the right care more quickly.

Temporary Pain Relief While You Wait

If you are waiting for a dental appointment, the NHS recommends these measures to manage pain at home:

Do:

• Take paracetamol or ibuprofen (follow the packet instructions for dosage)
• Rinse your mouth with warm salt water -- dissolve half a teaspoon of salt in warm water, rinse, and spit out (do not give salt water rinses to children)
• Use a pain-relieving dental gel from your pharmacy
• Eat soft foods and avoid chewing on the painful side
• Use a soft toothbrush and avoid flossing around the sore tooth

Do not:

• Place aspirin directly on your gum or tooth -- this causes chemical burns to the soft tissue
• Eat foods that are very hot, very cold, or sweet
• Smoke -- the NHS states this can make dental problems worse
• Visit your GP for dental pain -- they cannot provide dental treatment

"If you're in pain while waiting for a dental appointment, you can ask a pharmacist for advice on taking painkillers." -- NHS, Emergency Dental Care

For jaw and facial pain from grinding (bruxism): The NHS recommends applying ice packs wrapped in a towel to the jaw, taking paracetamol or ibuprofen, massaging the jaw muscles, and eating a soft diet to reduce jaw strain.

NHS Costs for Pain-Related Dental Treatment

If you are seen by an NHS dentist, treatment costs are structured in bands. You pay one charge per course of treatment, even if multiple appointments are needed.

Current NHS dental charges in England (from 1 April 2025):

When to See a Dentist About Tooth Pain

As a general rule: if dental pain is affecting your daily life, do not wait. Even mild pain that has lasted more than two days deserves professional assessment, because early treatment is almost always simpler, less invasive, and less costly.

How to access dental care:

• If you have a regular dentist: Phone your surgery directly and describe your symptoms. Many practices reserve same-day or next-day slots for urgent cases.
• If you do not have a dentist: Call NHS 111 (available 24 hours) or visit 111.nhs.uk. They will refer you to an urgent dental care provider.
• If it is a life-threatening emergency: Call 999 or go to A&E. This applies only if you have severe swelling affecting your breathing or vision, or uncontrolled bleeding.

Important: Do not contact your GP for dental pain. The NHS states clearly: "Do not go to a GP surgery as they will not be able to give you dental treatment."

Frequently Asked Questions

How do I know if my tooth pain is from a nerve?

Nerve-related tooth pain typically lingers for more than 30 seconds after the trigger is removed, occurs spontaneously without any stimulus, radiates to the ear or jaw, and involves sensitivity to both hot and cold (not just one). Pain that wakes you up at night is another strong indicator of nerve involvement. If you notice these signs, contact your dentist promptly -- nerve damage often requires root canal treatment.

Why does my tooth hurt but there is no cavity?

Several conditions cause tooth pain without visible decay. A cracked tooth may be invisible to the naked eye but causes pain when biting. Gum recession can expose sensitive root surfaces. Teeth grinding (bruxism) causes jaw and tooth ache without cavities. Sinus infections can produce pain in upper back teeth. Even referred pain from temporomandibular joint (TMJ) problems can feel like a toothache.

What type of toothache is a dental emergency?

Throbbing pain accompanied by facial swelling that reaches your eye or neck, difficulty breathing or swallowing, a high temperature, or uncontrolled bleeding constitutes a dental emergency. Call 999 or go to A&E for these symptoms. Severe pain not controlled by painkillers warrants urgent (not emergency) care through NHS 111.

Can sinus problems cause tooth pain?

Yes. The roots of your upper back teeth sit very close to the maxillary sinuses. When sinuses become inflamed or infected, it can produce a dull ache in these teeth. Sinus-related dental pain is usually bilateral (affecting teeth on both sides), may worsen when bending forward, and is often accompanied by nasal congestion or a feeling of facial pressure.

What does it mean if tooth pain comes and goes?

Intermittent dental pain usually indicates an early-stage problem: beginning tooth decay, a hairline crack that opens and closes under biting pressure, or mild (reversible) pulpitis. While not immediately dangerous, intermittent pain is your tooth warning you that something is developing. Seeing a dentist at this stage often means a simple filling rather than the root canal treatment or extraction you might need if you wait.

Is it normal for a tooth to hurt after a filling?

Some sensitivity after a new filling is normal and typically settles within two to four weeks. However, if pain is getting worse rather than better, you feel a sharp pain when biting down (which may indicate the filling is slightly too high), or you develop throbbing or spontaneous pain, contact your dentist. These signs suggest the filling may need adjustment or that the tooth pulp has been affected.

What is the difference between toothache and gum pain?

Toothache tends to be sharper, more localised to a specific tooth, and often triggered by temperature or biting. Gum pain is usually duller, more diffuse, and accompanied by visible signs such as redness, swelling, or bleeding when brushing. Toothache may indicate decay, a crack, or nerve problems; gum pain usually points to gum disease, an abscess in the gum tissue, or irritation from food debris. Both warrant a dental assessment if they persist for more than a few days.
