Acute toothache: what to do at home before your visit, and what NOT to do

Updated 2026-06-22 · Author: Dmytro Kobozev, restorative dentist and head doctor

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:

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.

What you must NOT do

Some folk remedies are not merely useless: they can make things worse and complicate the treatment that follows.

When you need emergency care

Seek urgent care the same day if the pain is accompanied by any of these red flags:

These are signs that the infection is spreading beyond the tooth. In that situation there is no time to lose.

A note for patients

A short reminder for when a tooth starts hurting in the evening or at the weekend and you still have to get to your appointment.

What you can do

  • Take a painkiller by mouth, following the label
  • Clean the tooth gently and use floss
  • Rinse with warm water or a salt solution
  • Hold something cool against the cheek for a few minutes
  • Sleep with your head slightly raised
  • Book a dentist as soon as possible

What you must NOT do

  • Warm the tooth or cheek, or use hot rinses
  • Place aspirin or any tablet on the gum
  • Take antibiotics on your own
  • Rinse with spirits or hold alcohol in the mouth
  • Try to open or extract the tooth yourself
  • Put up with it for days and postpone the visit

The doctor's view

"The commonest mistake patients arrive with is trying to sit out acute pain on painkillers. The tablet switches off the symptom, while the inflammation of the nerve or around the root quietly advances. The longer you wait, the smaller the chance of keeping the tooth alive, and the more often root canal treatment — or even extraction — becomes necessary. The second common mistake is warming the cheek: where there is pus, heat works against you. So the rule is simple: take the painkiller, do not apply heat, and book the earliest appointment. Modern treatment under a microscope can, in most cases, stop the pain and save the tooth — if you come in time." — Dmytro Kobozev, head doctor of the Houston clinic.

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.

After the first consultation you receive a digital A treatment roadmap — a step-by-step plan with prices, and no surprises along the way.

The cause of the pain and the treatment plan are established by a doctor after an examination; the final decision is taken at an in-person consultation.

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.
