Acute toothache: what to do at home before your visit, and what NOT to do
Acute toothache nearly always means inflammation — of the tooth's nerve or of the tissue around the root — and it does not resolve by itself. Before you see a dentist you can safely ease the pain with an oral painkiller and something cool on the outside of the cheek. What you must not do is warm the tooth, put tablets on the gum, or take antibiotics on your own. If the pain comes with facial swelling, a fever or difficulty swallowing, you need emergency care.
Why a tooth hurts
Pain is a signal, not a diagnosis. Several different causes can lie behind it, and the treatment depends on which one:
- Deep decay. A brief pain from sweet, cold or hot things, which fades quickly once the trigger is removed.
- Pulpitis — inflammation of the nerve. The pain is severe and throbbing, often worse at night, and radiates to the ear, the temple or the neighbouring teeth. Painkillers help only briefly.
- Periodontitis of the root apex — inflammation near the tip of the root. The tooth hurts when you bite on it and feels as though it has grown taller and stops the jaws closing.
- A cracked tooth. A sharp pain at one particular moment as you bite.
- Pericoronitis — inflammation of the gum over an erupting wisdom tooth.
- Pain after recent treatment or a new filling — a normal reaction for the first few days, but it needs checking if it grows worse.
Only an examination, often with an X-ray, establishes the exact cause. Telling pulpitis from apical periodontitis on your own is difficult — and in any case what you should do at home before the appointment is much the same.
What you can do at home before the visit
The aim at home is only to reduce the pain and do no harm until you reach the dentist. It is not treatment.
- Take a painkiller by mouth. An over-the-counter NSAID (ibuprofen, for instance) or paracetamol, at the dose on the label and provided there are no contraindications. Swallow the tablet with water.
- Clean the tooth carefully. If food trapped in the cavity or between the teeth is triggering the pain, brush gently and use floss.
- Rinse the mouth with warm (not hot) water or a weak salt solution, to clear away food debris.
- Hold something cool against the outside of the cheek for a few minutes if there is swelling — it may ease the discomfort a little.
- Sleep with your head slightly raised — throbbing pain often feels worse lying flat.
What you must NOT do
Some folk remedies are not merely useless: they can make things worse and complicate the treatment that follows.
- Warming the tooth or the cheek with a hot water bottle, a warm compress or a hot rinse. Heat increases the inflammation and the swelling and speeds the spread of pus.
- Placing a tablet (aspirin or similar) on the tooth or gum. It does not relieve pain, but it does cause a chemical burn of the mucosa.
- Taking antibiotics on your own. They do not relieve pain, they do not replace treatment, and they encourage bacterial resistance. Only a doctor decides whether they are needed.
- Rinsing with spirits to "warm things up" or holding alcohol in the mouth — the mucosa is injured and the problem remains.
- Trying to open, drill or extract the tooth yourself.
- Enduring several days on painkillers in the hope it will pass. The pain may quieten for a while, but the process usually advances.
When you need emergency care
Seek urgent care the same day if the pain is accompanied by any of these red flags:
- noticeable swelling of the face, cheek, neck or under the eye;
- a fever or general weakness;
- difficulty swallowing or breathing;
- an inability to open the mouth wide;
- severe throbbing pain that painkillers do not touch.
These are signs that the infection is spreading beyond the tooth. In that situation there is no time to lose.

The doctor's view
How the cause of the pain is treated at the Houston clinic
At the appointment the doctor finds the cause of the pain — with an X-ray if needed — and deals with that, not just the symptom. All restorative work at the clinic is carried out under a microscope, which makes it possible to remove the diseased tissue precisely and, where possible, to save the tooth.
- Restorative work and cosmetic restoration (decay, rebuilding the tooth) — from UAH 1 750.
- Endodontics under a microscope (root canal treatment or retreatment for pulpitis or apical periodontitis) — from UAH 6 600.
- Oral surgery and extractions — from UAH 2 100, when the tooth can no longer be saved.
After the first consultation you receive a digital A treatment roadmap — a step-by-step plan with prices, and no surprises along the way.
Frequently asked questions
Can I put up with acute toothache and wait for it to pass?
No. Toothache rarely passes without consequence — most often it means inflammation of the nerve (pulpitis) or of the tissue around the root. Even if the pain quietens for a time, the process usually advances. A painkiller helps you get to the appointment; it does not treat the cause. Book a dentist as soon as you can.
Which painkiller can I take for toothache?
Usually an over-the-counter NSAID such as ibuprofen, or paracetamol, at the dose on the label and provided there are no contraindications. The tablet is swallowed with water, not placed on the tooth or gum. If you have a chronic illness, are pregnant, or take other medicines, agree the drug and the dose with a doctor or pharmacist.
Why must I not warm an aching tooth or cheek?
Heat increases the blood flow and can speed the spread of a purulent infection and worsen the swelling. Warm compresses, a hot water bottle and hot rinses are contraindicated in acute pain. If there is swelling you may hold something cool against the outside briefly — but the essential thing is to see a dentist.
When is toothache a reason to seek urgent care?
Seek help immediately if the pain comes with marked swelling of the face or neck, a fever, difficulty swallowing or breathing, swelling under the eye, or an inability to open the mouth. These are signs of spreading infection and require emergency care.
Can I start taking antibiotics for toothache on my own?
No. Antibiotics do not relieve toothache and do not replace treating the cause. Taking them on your own breeds bacterial resistance and blurs the clinical picture. Only a doctor, after an examination, decides whether one is needed.
