In brief
For a severe toothache, the immediate steps are: rinse gently with warm salt water, floss carefully to remove any trapped debris, take over-the-counter pain relief as directed on the package, apply a cold compress to the outside of the face if there is swelling, and contact a dental office promptly. Severe tooth pain almost always signals a problem — deep decay, infection, a cracked tooth — that home care can soothe but not fix, so the real treatment is an examination.
Key takeaways
- Salt-water rinses, careful flossing and package-directed pain relief are safe first steps.
- Never place aspirin against the gum; it chemically burns the tissue.
- Pain that suddenly disappears can mean the nerve has died — the problem remains.
- Swelling, fever or trouble swallowing changes a toothache into an emergency.
Safe steps you can take now
Rinse with warm salt water. Half a teaspoon of salt in a cup of warm water, swished gently, helps clean the area and can ease irritated tissue.
Floss around the painful tooth. A trapped popcorn hull or food fragment pressing on the gum can produce surprisingly intense pain. Careful flossing sometimes brings real relief.
Use over-the-counter pain relief as directed. Follow the package instructions for whichever product you normally use, and check with a pharmacist if you take other medications or have health conditions. Pain relief is a bridge to care, not a substitute for it.
Cold compress for swelling. Fifteen to twenty minutes against the outside of the cheek can reduce swelling and dull pain, particularly after trauma.
Keep your head elevated. Lying flat increases blood pressure in the head and often intensifies throbbing pain, which is why toothaches feel worse at night. An extra pillow helps.
What to avoid
Do not place an aspirin tablet against the gum or tooth — this old remedy causes chemical burns without treating the pain. Avoid very hot, very cold or sugary foods that provoke the tooth, and chew on the other side. Do not apply heat to the outside of the face if infection is possible, as warmth can encourage swelling to spread. And do not assume that pain fading on its own means recovery: when a toothache abruptly disappears after days of severity, the nerve inside the tooth may have died, while the infection continues silently — a pattern explained in signs you may need root canal treatment.
What severe tooth pain usually means
Toothaches severe enough to disturb sleep typically involve the nerve of the tooth: deep decay reaching the pulp, infection at the root, a crack, or a failing old filling. Depending on the diagnosis, treatment may involve a filling, root canal treatment or, in some cases, extraction. The specific cause cannot be identified without an examination and usually an X-ray — which is why prompt assessment through a clinic’s emergency dentistry process matters more than any home remedy.
When a toothache becomes an emergency
Seek care urgently — the same day where possible — for toothache combined with facial swelling, fever, a bad taste suggesting a draining abscess, or pain following trauma. The combination of swelling and tooth pain is covered in detail in facial swelling and tooth pain.
Call 911 or seek emergency medical care for trouble breathing, trouble swallowing, uncontrolled bleeding, major facial trauma or other potentially life-threatening symptoms.
When to contact a dentist
Any toothache that is severe, lasts more than a day or two, wakes you at night or keeps returning deserves an examination — soon, not at the next routine checkup. Early treatment is almost always simpler, more comfortable and more tooth-preserving than late treatment.

Frequently asked questions
Why is my toothache worse at night?
Lying down increases blood pressure in the head, intensifying pressure inside an inflamed tooth. Fewer daytime distractions also make pain more noticeable. Night-time throbbing is a classic sign of nerve inflammation.
Can antibiotics cure a toothache?
Antibiotics may control a spreading infection temporarily, but they cannot remove the source inside the tooth. Without dental treatment — a filling, root canal or extraction — the problem returns.
Do clove oil or other home remedies work?
Clove oil has mild numbing properties and may take the edge off briefly. Like all home measures, it manages symptoms without treating the cause, and undiluted oil can irritate tissue. Use sparingly, if at all.
How quickly should a severe toothache be seen?
Ideally within a day or two, and the same day if there is swelling, fever or the pain is unbearable. Contact the clinic, describe your symptoms, and the team can advise the appropriate urgency.
