Pain from a broken tooth usually means the inside of the tooth or the gum is irritated, and it needs a dentist even if the pain comes and goes. Until you are seen, eat soft food, avoid very hot and cold drinks, and keep the area clean. Seek urgent care for swelling, fever, a bad taste or pus, or pain that medicine does not control. Trouble breathing or swallowing is a medical emergency.
This guide covers the wait, the warning signs, and what recovery usually looks like after the common treatments. If you want to compare the repair choices themselves first, see our guide to chipped and broken tooth repair options.
Why a broken tooth hurts
Under the enamel is dentin, which is more sensitive, and inside the tooth is the pulp with its nerve. When a break exposes either, air, temperature, sugar or biting pressure can trigger pain. A sharp edge can also cut the tongue or cheek, and the gum around the tooth can become sore. If bacteria reach the pulp, the pain can become constant and the tooth may become infected.
How much it hurts does not reliably show how serious the damage is. A deep crack may ache only now and then, while a small chip can feel very sharp. That is why an exam matters more than the pain level.
What you can do until you are seen
- Choose soft food and chew on the other side.
- Avoid extremes: very hot, cold or sugary food and drink can set off the pain.
- Use a cold compress on the outside of the cheek for swelling or soreness, for short periods.
- Cover a sharp edge with dental wax or a piece of sugar-free gum.
- Rinse gently with warm water and keep brushing, carefully, around the tooth.
- For pain medicine, follow the label and ask a pharmacist or clinician what is safe for you. The ADA acute dental pain guideline supports over-the-counter options for short-term relief. Never place aspirin on the tooth or gum.
Medicine and home care only ease symptoms. They do not repair the tooth. Write down what you took and when, and bring that to the visit.
Which warning signs are urgent?
| What you notice | What to do |
|---|---|
| Difficulty breathing or swallowing, or swelling spreading toward the eye or neck | Emergency medical care now. Call 911 for breathing problems. |
| Facial swelling, fever, a bad taste or pus near the tooth, or pain that medicine does not control | Contact a dentist urgently. Read about tooth infection treatment. |
| Throbbing pain that wakes you up or lingers after hot or cold | Ask for a prompt appointment. The nighttime toothache guide may help. |
| Short sensitivity or a rough edge, no swelling | Book the next suitable appointment. |
If you are unsure whether to go to a dentist or the emergency room for infection symptoms, see dentist or ER for a tooth infection.
What recovery usually looks like
Recovery depends on the treatment. The points below are typical, and your dentist’s own instructions come first.
After bonding or a filling
The numbness from the anesthetic wears off after a few hours. Avoid chewing until it has, so you do not bite your cheek or tongue. Some temperature sensitivity can follow. If your bite feels high or sensitivity does not settle, tell the office.
After a crown
You may first have a temporary crown. Avoid sticky and very hard food on that side, and tell the office if the temporary comes off. Mild soreness around the gum is common at first. A bite that feels uneven should be adjusted.
After a root canal
The tooth can feel tender for a few days, especially when you bite. Follow the medicine advice you are given. A root-canal-treated tooth often needs a crown afterward to protect it, so do not skip that appointment. Our page on emergency root canal treatment explains the steps.
After an extraction
A blood clot forms in the socket and protects healing. Avoid smoking, avoid poking the area and stick to soft food. Call the office for bleeding that does not stop or pain that gets worse after the first few days. See emergency tooth extraction for what happens.
If the pain does not improve as expected after treatment, or new swelling or a fever appears, call instead of waiting.
Different teeth, different questions
A broken front tooth raises appearance and function questions, and a broken back tooth usually involves chewing force and a larger repair. A broken tooth with a swollen gum can point to infection, so read when swelling around one tooth needs checking. A broken wisdom tooth is a separate case; see our wisdom tooth pain page.

Broken tooth pain questions
Why does a broken tooth hurt more at night?
Lying down can increase blood flow to the head, and with fewer distractions you notice pain more. The timing does not show the cause. Pain that wakes you needs a dental appointment.
Can I treat an infected broken tooth with antibiotics alone?
No. Antibiotics are sometimes added when an infection has spread, but the source in the tooth must be treated. Do not use leftover antibiotics.
How long does recovery take?
It depends on the treatment. Many people feel better within a few days of a filling, while a root canal or extraction can be sore for longer. Your dentist can give you a realistic timeline.
General education only. A dentist must examine the tooth before recommending treatment.
