A constant toothache can be exhausting. Whether the pain is dull and persistent or sharper and harder to ignore, the experience of ongoing dental discomfort naturally raises questions: What can I safely do right now? Is this serious? Should I be worried?

This article is designed to answer those questions calmly and clearly. It covers practical, low-risk steps that may help you manage discomfort temporarily while you wait for a dental assessment. It also explains why persistent tooth pain should not simply be managed at home indefinitely, and which symptoms may require more prompt dental attention. If you want a broader overview, this guide on common causes of toothache is a helpful companion.

Important: The guidance in this article is general educational information. It does not identify the cause of your toothache or replace a clinical dental assessment. Persistent dental pain should always be evaluated by a suitably qualified dental professional.

What Constant Toothache Can Mean

Persistent or continuous tooth pain can have a number of possible causes. A dental assessment is the appropriate way to identify what is happening in your specific situation — no article can do that for you. However, understanding the range of possible reasons may help ease some of the uncertainty while you wait.

Causes that a dentist may consider include:

Dental decay (tooth decay / caries): When decay progresses through the enamel and into the deeper layers of a tooth, it can cause ongoing discomfort, particularly when eating or drinking. You can compare symptoms with progressive tooth decay symptoms.
Inflammation of the dental pulp (pulpitis): The soft tissue inside the tooth, known as the pulp, contains nerves and blood vessels. When it becomes inflamed, often as a result of decay, trauma, or a cracked tooth, it can cause significant and persistent pain.
Dental infection or abscess: An infection at the root of a tooth or in the surrounding gum tissue can produce constant tooth pain, sometimes with swelling, a bad taste, or sensitivity to pressure. Look out for warning signs of dental abscess.
A cracked or fractured tooth: Cracks in teeth can be difficult to see and may cause pain that varies depending on the direction of pressure when biting.
A damaged or lost filling or crown: If a restoration is damaged or has come away, the exposed tooth may be sensitive or painful.
Gum-related problems: Certain gum conditions can cause localised dental pain or sensitivity that persists.
Dental trauma: A knock or injury to a tooth can cause ongoing pain, even when there is no obvious visible damage.
Tooth sensitivity: In some cases, persistent sensitivity to temperature or pressure can feel like continuous pain, particularly in people with exposed dentine or receding gums.

This list is not exhaustive, and one person's constant toothache may have a very different cause from another's. Only a clinical examination — and where appropriate, dental X-rays — can begin to establish what is happening.

Practical Self-Care Before Dental Assessment

The steps below may help reduce the level of discomfort you are experiencing while you wait for a dental appointment. They are general in nature, and their effectiveness will vary depending on the underlying cause of your pain.

These measures are for temporary symptom management only. They do not treat the cause of your toothache.

1. Keep the mouth as clean as possible

Maintaining oral hygiene is important even when you are in pain. Allowing plaque and food debris to accumulate around a painful tooth may worsen irritation. Gentle brushing with a soft-bristled toothbrush, used carefully around the affected area, is generally advisable.

If flossing around the painful tooth causes significant discomfort, try gently removing any trapped food with an interdental brush or by gently rinsing the area.

2. Rinse with warm salt water

Rinsing with a warm salt water solution — approximately half a teaspoon of salt dissolved in a cup of warm water — can help to keep the area around a painful tooth clean and may reduce localised gum irritation. This is a simple, low-risk measure. It does not treat any underlying dental condition, but many people find it temporarily soothing.

3. Avoid obvious triggers where possible

If you notice that certain temperatures or foods consistently worsen the pain, try to avoid them while you wait for assessment. Common triggers can include very hot or very cold foods and drinks, very sweet foods, and biting on hard items. Avoiding these where practical may reduce the frequency or intensity of pain episodes.

4. Rest and reduce physical stress on the tooth

Avoid chewing directly on the side of the mouth where the pain is located if this is comfortable and practical. Chewing on the opposite side may reduce the mechanical pressure on the affected tooth.

5. Stay hydrated

Keeping well hydrated is always advisable. Dry mouth can sometimes worsen dental discomfort. Sipping cool (not ice-cold) water can help maintain comfort.

6. Use over-the-counter pain relief appropriately

See the specific section on pain relief below.

What to Avoid When You Have Toothache

Some commonly shared home remedies for toothache are not supported by reliable evidence and may cause harm. The following should be avoided:

Placing aspirin directly against the tooth or gum: Aspirin is an acid and can cause chemical burns to soft tissue when applied directly. It is not a safe or effective local treatment for toothache.
Applying household substances to the tooth: Do not apply household chemicals, bleach, or other non-dental products to teeth or gums.
Poking or probing a painful tooth: Avoid using objects to probe or scrape around a painful tooth. This can damage soft tissue and push bacteria into vulnerable areas.
Delaying assessment in the hope that the pain will resolve: While some minor dental discomfort can settle, constant tooth pain that persists over several days should not simply be managed at home indefinitely. It generally indicates that something requires clinical assessment.
Combining pain relief medicines without guidance: Do not combine over-the-counter pain relief medicines unless the combination is supported by current product guidance and appropriate professional advice. Read the product information carefully and, if in doubt, speak with a pharmacist.

Eating and Drinking With Toothache

What you eat and drink can influence the level of discomfort you experience while waiting for dental assessment.

Practical adjustments that may help:

Choose softer foods where chewing is painful. Soup, mashed potato, scrambled eggs, yoghurt, and similar foods may be more comfortable to eat temporarily.
Avoid very hard or crunchy foods that require significant biting force, as these may increase pain, particularly if the cause is a cracked tooth or damaged restoration.
Avoid extremely hot or cold foods and drinks if temperature changes worsen your symptoms. Try lukewarm or room-temperature foods and drinks temporarily.
Limit very sweet foods and drinks where possible. Dental decay and exposed dentine can be particularly sensitive to sugar.
Avoid acidic foods and drinks where practical — citrus fruits, fizzy drinks, and vinegar-based foods can irritate already sensitive tooth surfaces.

These adjustments are practical, temporary measures. Your normal diet can be resumed following appropriate dental treatment once the underlying cause has been identified and managed.

Oral Hygiene During Toothache

It is understandable to feel cautious about brushing near a painful tooth. However, maintaining oral hygiene remains important even when a tooth is causing discomfort.

Allowing plaque to accumulate around a painful tooth or the surrounding gum may contribute to further irritation and does not help the healing process. Gentle but consistent cleaning is generally preferable to avoiding the area altogether.

Practical guidance:

Use a soft-bristled toothbrush and apply gentle pressure around the affected area.
Continue to brush the rest of your teeth normally.
Use a fluoride toothpaste appropriate for adult use.
If your toothpaste contains a sensitivity-relief ingredient, this may help in some cases — speak with your pharmacist or dentist if you are unsure which product is appropriate for you.
Rinse gently after brushing rather than vigorously, which can temporarily remove the fluoride benefit.

If brushing causes significant bleeding, substantial swelling, or a marked worsening of your pain, note this and discuss it with your dentist promptly. Do not use it as a reason to stop cleaning your teeth entirely.

Pain Relief Considerations

Over-the-counter pain relief medicines may help to reduce the discomfort associated with a constant toothache temporarily. The following points are provided for general information only.

Important notes:

Always read the product information carefully before taking any medicine.
Follow the dosing instructions on the packaging.
Some medicines may not be suitable for everyone — for example, people with certain medical conditions, those taking other medicines, pregnant women, breastfeeding women, children, and older adults may need to take different precautions or avoid certain products. If you are unsure, speak with a pharmacist.
Do not exceed the recommended dose.
Do not take pain relief medicine simply to postpone seeking dental assessment.
OTC pain relief can reduce the perception of pain temporarily. It does not treat the underlying dental problem.

Common types of OTC pain relief that are sometimes used for dental pain in the UK include paracetamol and ibuprofen. A pharmacist can advise you on what may be appropriate for your situation based on your individual circumstances.

Do not place pain relief tablets directly against a tooth or gum. Swallow tablets as directed by the product instructions.

If you are relying on OTC pain relief regularly for toothache that will not go away, this is a clear signal that a dental assessment is needed.

When Constant Toothache Needs Dental Assessment

A toothache that persists for more than a day or two — particularly one that is constant rather than occasional — generally warrants a dental assessment. Pain that does not resolve on its own, or that requires regular pain relief to remain manageable, is your body's way of signalling that something needs attention.

Reasons why persistent dental pain should be assessed rather than repeatedly self-managed include:

The underlying cause cannot be established without clinical examination. Only a dentist can identify what is causing your pain through examination, appropriate questioning, and where necessary, dental X-rays.
Some causes of constant toothache can worsen without treatment. Dental decay, pulp inflammation, and dental infections do not typically resolve without clinical management.
Early assessment may result in simpler treatment. Problems identified earlier may be more straightforward to manage than those that have been present for a longer period.
Pain management alone is not treatment. Managing symptoms temporarily is entirely appropriate while you wait for assessment, but it is not a substitute for it.

If you are registered with a dental practice, contact them to arrange an appointment. If you are not currently registered or cannot access your usual dental practice promptly, NHS 111 can provide guidance on accessing NHS dental services in your area. This related guide on when to book dental appointments may also help you decide timing.

When Toothache May Need Urgent Dental Attention

Most cases of toothache can be assessed at a routine or near-term dental appointment. However, certain symptoms may indicate a more pressing situation that warrants prompt dental contact.

Consider seeking urgent dental advice if you experience any of the following:

Swelling of the face, jaw, or neck
Swelling that is spreading or worsening
Difficulty opening your mouth fully
Difficulty swallowing or breathing
A high temperature (fever) alongside your toothache
A tooth that has been knocked out or significantly loosened due to trauma
Severe pain that over-the-counter medicines are not reducing
Pus, discharge, or an unpleasant taste that has developed around the affected tooth
Signs of a spreading or worsening infection

If you experience difficulty breathing or swallowing alongside dental swelling, seek emergency medical care immediately by calling 999 or attending your nearest A&E department.

For urgent dental concerns that do not require emergency medical care, contact your dental practice directly. If they are unavailable, NHS 111 (available by calling 111 or via 111.nhs.uk) can advise on accessing urgent dental services. If needed, review same-day emergency dentist options.

The absence of swelling does not mean that persistent toothache is insignificant. Constant pain in a tooth can still indicate a problem that requires clinical attention, even when there is no visible swelling. Do not delay seeking assessment on the basis that you cannot see anything wrong.

What Happens During a Dental Assessment?

If you have not visited a dentist recently, you may be uncertain about what an assessment for toothache involves. Understanding the process can make it feel more manageable.

A dental assessment for toothache typically involves:

A conversation about your symptoms: Your dentist will ask when the pain started, what makes it better or worse, whether it is constant or intermittent, and whether you have experienced any other symptoms.
A clinical examination: Your dentist will examine the affected tooth or teeth, the surrounding gum tissue, and potentially other teeth in the area. They may gently tap on teeth or apply temperature stimuli to help identify which tooth is causing the problem and to gain information about its condition.
Dental X-rays where appropriate: X-rays can help identify decay, infection, bone changes, or structural problems that are not visible during a surface examination.
Discussion of findings and options: Your dentist will explain what they have found and discuss the options available to you. The appropriate next step will depend entirely on what the assessment reveals.

The assessment itself is a clinical information-gathering process. It does not guarantee a particular outcome or commit you to a specific treatment. It does, however, allow a qualified professional to establish what is happening and advise you accordingly.

Frequently Asked Questions

Why does my toothache stay constant rather than coming and going?

Toothache that is constant — rather than triggered only by eating, drinking, or temperature — can sometimes suggest that the nerve tissue inside the tooth (the dental pulp) is significantly inflamed or affected. However, constant pain can also result from other causes, including infection, a cracked tooth, or gum problems. A dental assessment is needed to establish the reason in your individual case.

Can constant toothache go away by itself?

In some cases, mild dental discomfort may settle — for example, if it is related to temporary sensitivity or minor gum irritation. However, toothache that is constant and persistent over several days generally does not resolve without clinical attention. The underlying cause — whether that is decay, pulp inflammation, infection, or damage — typically requires dental treatment to address. Waiting for the pain to go away on its own is not advisable when pain is ongoing.

Can I brush my teeth if I have toothache?

Yes, in most cases. Gentle but consistent oral hygiene remains important even when a tooth is painful. Use a soft-bristled toothbrush and apply careful pressure around the affected area. Allowing plaque to build up around a painful tooth may worsen irritation and is generally unhelpful. If brushing causes significant bleeding or substantial new swelling, mention this to your dentist promptly.

What foods should I avoid with toothache?

Try to avoid very hot, very cold, hard, crunchy, or very sweet foods and drinks, as these can trigger or worsen discomfort depending on the cause of your toothache. Soft, lukewarm foods are often more comfortable to eat temporarily. These are practical adjustments for comfort — they are not a treatment for the underlying cause.

Why does my tooth hurt more at night?

Many people notice that toothache seems worse at night. This may be partly because there are fewer daytime distractions, making pain more noticeable. Some people also find that lying down increases blood pressure in the head and face, which can heighten the perception of dental pain. If night-time toothache is significantly affecting your sleep, this is another reason to seek prompt dental assessment.

Can a tooth hurt without any visible swelling?

Yes. Persistent tooth pain does not always present with visible swelling. Many dental problems — including pulp inflammation, early infection, or a cracked tooth — can cause significant discomfort without obvious external signs. The absence of swelling does not mean the problem is minor or that a dental assessment is not needed.

How long should I wait before seeking dental advice for constant toothache?

If toothache is constant and has persisted for more than a day or two, it is sensible to contact a dental practice. You do not need to wait until the pain becomes unbearable. Earlier assessment generally allows for more straightforward clinical management. If you cannot access your usual dental practice promptly, NHS 111 can help you find an appropriate dental service.

When is toothache considered a dental emergency?

Toothache accompanied by facial or neck swelling, fever, difficulty swallowing or breathing, spreading swelling, or severe uncontrolled pain may indicate a dental emergency. In these circumstances, contact your dental practice urgently or call NHS 111. If you have difficulty breathing or swallowing, call 999 or attend A&E immediately. Dental trauma — such as a knocked-out tooth — also warrants urgent dental attention.

Is it safe to use clove oil for toothache?

Eugenol, the active compound in clove oil, has been used in dentistry for many years and is found in some licensed dental preparations. However, clove oil in its undiluted form should be used with significant caution, as it can irritate soft tissues if applied incorrectly. If you are considering using a clove oil product for temporary toothache relief, choose a product specifically designed for dental use, read the instructions carefully, and speak with a pharmacist if you are unsure. It remains a temporary measure only and does not address the underlying cause of toothache.

What if I am anxious about visiting a dentist?

Dental anxiety is extremely common and entirely understandable. It is worth letting your dental practice know in advance that you feel anxious, as many dental teams are experienced in supporting anxious patients. Avoiding dental assessment because of anxiety may allow the underlying cause of toothache to progress. Many dental practices offer a calm and patient-centred approach, and discussing your concerns with the team before your appointment can help.

Taking the Next Step

If you are experiencing a constant toothache that has not settled within a day or two, the most important and genuinely helpful step you can take is to arrange a dental assessment.

Safe self-care — keeping your mouth clean, managing discomfort with appropriate over-the-counter pain relief as directed, choosing softer foods, and avoiding obvious triggers — can help you manage in the short term. However, no amount of self-care can establish the cause of your pain or provide clinical treatment.

Persistent toothache deserves proper attention. Contacting your dental practice to arrange an assessment is a calm, sensible, and proportionate response to ongoing dental pain.
