Tooth pain: what it usually means
Toothache is not one condition. Where it hurts, what triggers it and how long it lasts point to quite different causes — and the difference decides whether you need to be seen today or next week.
What the type of pain tends to indicate
These patterns are common, but they overlap. Only an examination and usually an X-ray can confirm what is happening:
- Sharp pain with cold that stops quickly — often exposed dentine or a small area of decay
- Lingering pain after hot or cold — suggests the nerve inside the tooth is inflamed
- Pain when biting down — may be a crack, a high filling, or infection at the root tip
- Constant throbbing, worse lying down — usually an infected nerve or an abscess forming
- Dull ache around the back of the jaw — frequently a wisdom tooth
- Widespread ache, worse in the morning — often clenching or grinding rather than one tooth
Pain that stops is not the same as pain that is resolved
A tooth that hurt badly for days and then went quiet has sometimes not recovered — the nerve inside may have died, which ends the pain while the infection continues silently. It is one of the more common reasons people arrive later with a swelling that could have been avoided.
If severe pain disappears on its own without treatment, it still deserves an examination.
When to be seen, and how soon
This is general guidance, not a diagnosis. If you are unsure, message us and describe what is happening.
- Swelling of the face, cheek or under the jaw
- Difficulty swallowing, breathing or opening the mouth
- Fever alongside dental pain
- Pain following an injury to the face or a knocked-out tooth
- Pain that wakes you at night or is not controlled by ordinary painkillers
- A bad taste, discharge or a pimple-like spot on the gum
- Pain on biting that has lasted more than a few days
- A tooth that has changed colour
- Brief sensitivity to cold that settles within seconds
- Mild discomfort around a wisdom tooth that comes and goes
- Occasional twinges with sweet food
What you can do meanwhile
None of this treats the cause, but it can make waiting more bearable:
- Take your usual over-the-counter painkiller at the dose on the packet, unless a doctor has told you otherwise
- Keep your head raised — lying flat often makes throbbing worse
- Rinse gently with warm salty water
- Avoid very hot, very cold and very sweet food on that side
- Do not place aspirin or clove oil directly on the gum; it can burn the tissue
How we treat it
Which of these applies depends on the cause, which an examination confirms:
- Root canal treatment — when the nerve inside the tooth is infected
- Wisdom tooth removal — when the pain is coming from a wisdom tooth
- Crowns — when a cracked or heavily filled tooth needs protecting
- Gum treatment — when the ache is coming from the gum rather than the tooth
Common questions
Can a toothache go away on its own?
The pain can, but the cause usually does not. Pain that stops suddenly after being severe sometimes means the nerve has died, and the infection continues without symptoms. It is still worth an examination.
Are antibiotics enough for a dental infection?
Antibiotics may reduce swelling temporarily, but they do not remove the source. Dental infections are treated by dealing with the tooth itself. They should only be taken when a dentist or doctor has prescribed them.
How soon can I be seen for dental pain?
Message us on WhatsApp describing the pain and we will advise how urgently you need to be seen. Please note the clinic is closed on Thursdays.
Will I definitely need a root canal?
No. Plenty of toothache is caused by decay that only needs a filling, or by a gum problem. A root canal is only needed when the nerve inside the tooth is irreversibly affected.
