Severe Toothache at Night: What to Do Until You See a Dentist

Published: 18 September 2026 | Next Review Due: 18 September 2027

Introduction

Severe toothache at night is one of the most distressing dental problems a person can experience. Pain that arrives or intensifies after dark often feels impossible to manage — and the absence of open dental practices can make the situation feel even more alarming. Different dental problems can produce very similar symptoms, which is why self-diagnosis is unreliable and a professional dental examination may be necessary to identify the cause accurately.

Please note: Private Doctor London provides private blood testing, health screening and sexual-health testing. It does not provide dental examinations, dental treatment or emergency dental care. For dental concerns, please contact an appropriate dental professional.

For information on urgent dental conditions and what to expect, Emergency Dentist London provides educational guidance on severe toothache and the treatment options that may be available.

Quick Answer: What Should You Do for Severe Toothache at Night?

If you are experiencing severe toothache at night, take suitable over-the-counter pain relief in line with the packet instructions, avoid very hot, cold or sweet foods, and contact an emergency dental provider as soon as one is available. Dental pain can have several possible causes, and a dental examination may be required to identify and treat the underlying problem.

Urgent dental assessment may be appropriate if you have:

Severe or rapidly worsening dental pain
Visible facial or gum swelling
Fever or feeling generally unwell alongside the pain
Difficulty opening your mouth fully
Tooth pain following an injury or trauma
Bleeding that does not settle

Symptoms alone cannot confirm the underlying dental condition. A dental examination may be required.

Why Does Toothache Often Feel Worse at Night?

Many people notice that dental pain intensifies once they lie down to sleep. This is a well-recognised phenomenon with a straightforward physiological explanation. When you are horizontal, blood pressure in the head and neck increases slightly, which can heighten inflammation around an already aggravated tooth or surrounding tissues. During the day, distraction from routine activity can also mask the full extent of discomfort; at night, with fewer competing sensations, pain can feel more acute.

Night-time toothache does not always indicate a more serious condition than daytime toothache — however, pain that prevents sleep or wakes you from sleep consistently is a sign that professional dental assessment is unlikely to be safely delayed for long.

When Does Toothache Become a Dental Emergency?

Not all toothache demands immediate attention, but some presentations are genuinely urgent. A dental problem should be treated as a dental emergency if any of the following apply:

The pain is severe and unmanaged by appropriate over-the-counter pain relief
There is swelling of the face, jaw, neck or floor of the mouth
You feel feverish, shivery or generally unwell in addition to the dental pain
You cannot open your mouth or swallow comfortably
The tooth has been knocked out, fractured or involved in a facial injury
Bleeding from the mouth is significant and not settling

In these circumstances, contact an emergency dental provider as promptly as possible, or call NHS 111 for telephone triage and guidance on local dental services. Do not wait for a routine appointment if you have facial swelling or feel systemically unwell alongside dental pain. These signs may indicate a spreading dental infection that requires prompt professional assessment.

What Could Be Causing Severe Toothache at Night?

Dental pain can have several possible causes. The following are among the more common dental conditions associated with significant nighttime tooth pain, though they are not an exhaustive list and they are not presented as a diagnosis.

Tooth Decay (Dental Caries)

Decay that has progressed into the deeper layers of a tooth — toward or into the pulp — can produce intense, spontaneous pain. This type of toothache may throb and is often difficult to attribute clearly to a single tooth. It can worsen when lying flat.

Dental Abscess

A dental abscess is a pocket of infection that can form at the tip of a tooth root (periapical abscess) or within the surrounding gum tissue (periodontal abscess). It often produces a persistent, throbbing pain that may be accompanied by visible swelling, a bad taste in the mouth, or a raised temperature. Guidance on dental abscess symptoms and what to expect from emergency dental assessment is available from an appropriate dental information provider.

Cracked or Fractured Tooth

A crack in a tooth may not always be visible. Pain may be sharp and triggered by biting or temperature changes. Cracks can be difficult to diagnose without clinical examination and, in some cases, specialised dental imaging.

Damaged or Lost Filling

When a filling is lost or deteriorates, the underlying dentine becomes exposed. This layer is significantly more sensitive than the outer enamel and can produce acute pain in response to temperature, sweet foods or pressure.

Impacted or Erupting Wisdom Teeth

Wisdom teeth that are partially erupted or failing to emerge correctly can cause significant pain towards the back of the jaw, which may radiate to the ear, throat or neck. Gum tissue around an impacted wisdom tooth can also become infected.

Pulpitis

Pulpitis refers to inflammation of the dental pulp — the soft internal tissue of the tooth containing nerves and blood vessels. It may be reversible (where the pulp can heal) or irreversible (where it cannot). Irreversible pulpitis tends to produce severe, spontaneous, lingering pain and frequently occurs at night.

Gum Disease

Advanced gum disease (periodontitis) can cause significant pain, particularly if a periodontal abscess develops. Gum pain of this type may be less precisely located than toothache arising from a single tooth.

What Can You Do While Waiting for Dental Care?

The following temporary measures may help to reduce discomfort until a dental appointment is available. They are not a substitute for professional diagnosis and treatment, and they cannot resolve the underlying cause of the pain.

Take suitable over-the-counter pain relief. Common options available from a pharmacist include ibuprofen or paracetamol, taken in accordance with the printed instructions. Some individuals find that alternating the two (where this is appropriate) provides better coverage. Do not exceed the recommended dose.
Ask a pharmacist for guidance. Some over-the-counter pain medications are unsuitable for those who are pregnant, under a certain age, have specific health conditions, or are taking other medications. A pharmacist can advise on what is appropriate for you.
Rinse gently with warm salt water. This may help to keep the area around the affected tooth clean and could reduce minor gum irritation. Use approximately half a teaspoon of salt dissolved in a glass of warm water.
Apply a cold compress externally. Placing a cold compress or wrapped ice pack against the outside of the cheek for short intervals may help to reduce localised swelling and temporarily ease pain.
Avoid triggers. Very hot, very cold or sweet foods and drinks can exacerbate dental pain, particularly if the pain is related to exposed dentine or pulp involvement. Try to chew on the opposite side.
Elevate your head slightly when sleeping. Raising your head with an extra pillow may help to reduce the increase in blood pressure that can worsen dental pain when lying flat.

Temporary self-care may reduce discomfort, but it cannot diagnose or treat the underlying dental problem.

What Should You Avoid?

Certain commonly suggested home remedies are ineffective and may cause additional harm. Avoid the following:

Do not place aspirin directly on a tooth or gum. Aspirin is not designed for topical application in the mouth and can cause localised chemical burns to the soft tissue.
Do not attempt to drain or burst a dental abscess. This is not safe to do at home and does not remove the source of infection.
Do not use household glue on a tooth, crown or denture. Most household adhesives are toxic and can cause damage to soft tissues or make subsequent dental treatment more complex.
Do not use antibiotics that were not prescribed for your current problem. Leftover antibiotics may be the wrong type, the wrong strength or insufficient in quantity to treat a dental infection. Self-prescribing antibiotics is unsafe and can contribute to antibiotic resistance.
Do not assume that pain disappearing means the problem has resolved. Pulp death can result in a temporary reduction in pain. However, the infection or damage may continue to progress silently and require more extensive treatment later.
Do not ignore increasing facial swelling. Swelling that is spreading should be treated as urgent. See the emergency section below.

What Might a Dentist Do?

When you attend a dental appointment for severe toothache, the dental professional will typically:

Review your symptoms and dental history — including when the pain began, what makes it worse or better, and whether you have had any previous treatment on the affected tooth.
Examine the mouth and the affected tooth — including an assessment of the surrounding gum tissue, any visible swelling and the bite.
Take dental X-rays where appropriate — an X-ray may be needed to assess the root, surrounding bone and the extent of any infection or decay that is not visible on examination alone.
Discuss the findings and likely cause — based on the examination, the dentist will explain the most likely diagnosis and what it means.
Outline the treatment options available — along with a breakdown of associated costs, and obtain your informed consent before proceeding.

Depending on the clinical findings, possible treatment options may include:

A temporary or permanent filling to protect an exposed tooth
Root canal treatment to remove infected or inflamed pulp tissue
Drainage of a dental abscess
Extraction where a tooth cannot be predictably restored
Repair or assessment of a cracked tooth
Re-cementation or replacement of a lost crown

Treatment options depend entirely on the examination and clinical findings. Not all treatment may be completed in the first appointment; this will depend on the nature and extent of the problem. For information on what private emergency dental treatment in London may involve, contacting an appropriate dental provider directly is the most reliable way to understand current appointment availability and what to expect.

Can the Tooth Be Saved?

This is a question that many people ask, and it is an understandable concern. Whether a tooth can be retained depends on several clinical factors, including:

The extent of decay or damage
The location and depth of any crack or fracture
The amount of healthy tooth structure that remains
The presence and severity of infection
The condition of the surrounding bone and gum
Whether the tooth has been treated previously
How long the problem has been present before treatment is sought

A dental professional will discuss the realistic options after examination. It is not possible to determine in advance whether a tooth can be saved, and no article or online resource can make this determination. Prompt dental assessment generally improves the range of available treatment options.

When to Seek Immediate Medical Help

Call 999 or attend your nearest A&E department immediately if you develop any of the following:

Difficulty breathing or swallowing
Rapidly increasing swelling of the face, floor of the mouth, jaw or neck
Swelling extending toward or around the eye
Severe facial trauma or injury
Loss of consciousness or collapse
Heavy or uncontrolled bleeding from the mouth

These signs may indicate a serious and potentially life-threatening condition, such as a spreading deep-space dental infection (Ludwig's angina), that requires hospital-level emergency care. Do not attempt to drive yourself to hospital. Do not wait for a dental appointment in these circumstances.

For urgent but non-life-threatening dental concerns that cannot wait until the next working day, call NHS 111 for telephone advice and triage, or contact an emergency dental provider directly.

Frequently Asked Questions

Is severe toothache at night a dental emergency?

Severe tooth pain that prevents sleep, is associated with facial swelling, or is accompanied by fever should be assessed by a dental professional as promptly as possible. While not all toothache constitutes an emergency, these features suggest that the problem may require urgent attention. Contact an emergency dental provider or NHS 111 for guidance.

Can I wait until the morning to see a dentist?

If the pain is severe, worsening, or accompanied by swelling, fever or difficulty swallowing, it is inadvisable to wait without seeking at least telephone guidance from NHS 111 or an emergency dental provider. Temporary pain relief measures may help manage discomfort overnight, but they do not treat the underlying problem.

Can toothache go away without treatment?

Pain may sometimes reduce or disappear without treatment. However, this does not always mean the problem has resolved. Pulp death, for example, can cause pain to stop temporarily while an infection continues to develop. Unexplained resolution of significant dental pain should still be assessed by a dentist.

Should I go to A&E for severe toothache?

A&E departments are not generally resourced to provide dental treatment. However, if you have difficulty breathing or swallowing, rapidly increasing facial or neck swelling, or signs of severe systemic illness alongside dental pain, you should attend A&E immediately. For toothache without these features, NHS 111 or an emergency dental provider is a more appropriate first contact.

What can I take for toothache pain at night?

Suitable over-the-counter pain relief — such as ibuprofen or paracetamol taken in accordance with the packet instructions — may help to manage discomfort temporarily. Suitability depends on individual health factors, including pregnancy, age, allergies and current medications. A pharmacist can advise on what is appropriate. Never exceed the recommended dose.

Will an emergency dentist need to take an X-ray?

An X-ray is commonly used to assess the extent of decay, check for infection at the root tip, or evaluate the surrounding bone. Whether an X-ray is taken will depend on the clinical examination and the information needed to make an accurate assessment. An examination and, where appropriate, an X-ray may be required.
