Toothache That Won't Stop: When It's a Dental Emergency
Most toothache settles down, or at least makes sense, fairly quickly, sensitivity after a cold drink, a twinge after eating something hard. It's the toothache that keeps building, wakes you up at night, or doesn't respond to painkillers that tends to worry people, and rightly so.
This guide walks through what persistent tooth pain can mean and how to judge whether it needs to be seen to urgently, as part of our wider Dental Trauma and emergency care.
What Persistent Toothache Usually Means
Ongoing, worsening pain is often a sign that something inside or around the tooth needs attention rather than something that will resolve by itself. Common causes include:
- Untreated decay reaching the nerve of the tooth.
- A dental abscess, a build-up of infection at the root or in the gum, which can cause throbbing pain, swelling, and sometimes a bad taste.
- A cracked tooth, where the crack isn't visible but is irritating the nerve every time you bite.
- Gum disease, which can cause deep, dull discomfort around multiple teeth rather than one specific tooth. Our guide to gum disease covers the early signs in more detail.
- A failing filling or old restoration that's let bacteria in underneath.
Signs That Point to an Abscess
An abscess is one of the more urgent causes of toothache, and it's worth knowing the signs:
- A throbbing pain that doesn't ease with over-the-counter painkillers
- Swelling in the gum, cheek or jaw
- A bad taste from pus draining into your mouth
- Raised temperature or feeling generally unwell
Left untreated, an abscess can spread beyond the tooth, so this is one to act on quickly rather than wait out.
When to Treat It as an Emergency
Call us straight away, or seek emergency dental care if we're closed, or, if you have any of the following alongside the pain: facial or jaw swelling, difficulty swallowing or breathing, a fever, or pain that's severe enough to stop you sleeping or eating. These can indicate an infection that needs prompt treatment rather than something to manage at home.
If the pain is milder, intermittent, or clearly linked to something specific (a particular tooth, a particular trigger like cold drinks), it's still worth booking an appointment soon, but it's less likely to be a same-day emergency.
What You Can Do While You Wait to Be Seen
Over-the-counter painkillers taken as directed can help in the short term, a cold compress against the cheek can ease swelling, and avoiding very hot, cold or sugary food and drink on that side will reduce irritation. Avoid putting aspirin directly against the gum or tooth, it's a common myth that this helps, and it can actually damage the gum tissue.
What Happens at the Appointment
We'll examine the tooth and surrounding gum, and will likely take an X-ray to see what's happening below the surface, since the cause of toothache isn't always visible to the naked eye. Treatment depends entirely on the cause: this might mean a filling, root canal treatment, treatment for gum disease, or, if there's an abscess, draining the infection and prescribing antibiotics where appropriate.
Frequently Asked Questions
Can toothache go away on its own?
Mild, short-lived sensitivity sometimes does. Persistent or worsening pain almost always has an underlying cause that needs treating rather than waiting out.
Is it normal for toothache to come and go?
It can, particularly in the early stages of decay or a developing crack, but an intermittent ache is still worth having checked rather than waiting for it to become constant.
How do I know if I have an abscess?
Throbbing pain, swelling, a bad taste, or feeling generally unwell alongside the toothache are the key signs. If in doubt, contact us rather than waiting to see if it worsens.
Can antibiotics alone fix a dental abscess?
Antibiotics can help control infection, but they don't treat the underlying cause, the tooth itself will usually still need treatment such as root canal treatment or, in some cases, extraction.
What if I can't get a same-day appointment?
Call us and explain your symptoms, we'll advise on next steps and, if it's genuinely urgent and we can't fit you in, point you toward emergency dental services.
Persistent toothache is one of the more common reasons patients contact us, and it's almost always treatable once we know what's causing it. Visit our Dental Trauma page for more on how we handle dental emergencies, or get in touch and we'll get you seen.
