In plain English
What toothache usually means
Toothache is pain in or around a tooth, and it covers a wide range: a quick twinge with a cold drink, a dull ache when you chew, or a deep throb that wakes you at night. The pain comes from the nerve inside the tooth or from the tissues that hold the tooth in place, and those can be irritated by many different problems, from early decay to a crack, a failing filling, inflamed gums, clenching, or an infection. The character of the pain offers clues but not an answer. Sharp and brief often suggests an exposed or irritated surface; lingering, spontaneous or throbbing pain suggests the nerve itself is inflamed; pain on biting points toward the root, the bite or a crack. These patterns overlap, and pain can also be referred from a neighboring tooth or even the sinuses, so the tooth that hurts is not always the tooth at fault. Pain that persists should be checked by a dentist within 1 to 2 days, and immediately if it comes with fever, swelling, or difficulty breathing or swallowing.
- Cavities or tooth decay
- Decay often starts with no pain at all, then brings short twinges with sweet, cold or hot food as it gets closer to the nerve. A visible hole, a dark spot or food packing into one place can accompany it, though decay between teeth usually shows only on an x-ray.
- Gum disease
- Pain from the gums tends to be a dull, sore, sometimes itchy ache around several teeth instead of one sharp spot. Gums may look red or puffy, bleed when brushed, or have pulled back so the roots are exposed and sensitive to cold.
- Tooth infection or abscess
- An infected tooth often produces constant, throbbing pain that worsens when you lie down or bite, sometimes with a swollen gum, a bad taste or fever. This is the cause that turns a toothache into an urgent problem, and swelling or fever means being seen immediately.
- Damaged filling
- A filling that has cracked, loosened or fallen out leaves the softer inner tooth open. Typical signs are a rough or sharp edge against the tongue, food catching in a new gap, and sensitivity to temperature or sweetness in a tooth that was comfortable before.
- Teeth grinding
- Clenching or grinding, often during sleep, can make several teeth ache without any decay. The discomfort is usually worst on waking, may involve both sides, and can come with sore jaw muscles, headaches at the temples or flattened, worn biting edges.
- Erupting or impacted tooth
- A tooth pushing through, most often a wisdom tooth at the back of the jaw, can cause pressure, sore gum behind the last molar and pain that comes in episodes. If the gum over it swells or the jaw becomes hard to open, it needs prompt attention.
What a dentist does about it
The dentist will usually ask where the pain is, how long it lasts, what triggers it and whether it wakes you, because the pattern narrows the possibilities. The exam typically includes looking at each tooth and the gums, tapping teeth, having you bite on something to find a painful cusp, applying cold to see how the nerve responds, and taking x-rays to check for decay, a deep filling or changes at the root. Treatment depends entirely on what is found. It may be as simple as a filling, a replaced restoration, a bite adjustment or a night guard, or it may involve gum treatment, a root canal, a crown or removing the tooth. When the source is unclear, a dentist may monitor it or refer you to a specialist.
Until you can be seen
These measures are for comfort while you wait for an appointment, not a substitute for one. Over-the-counter pain relief can be taken as directed on the label, and a pharmacist can help you choose. A cold compress on the cheek and a gentle salt water rinse may help. Some people find a little clove oil on a cotton ball gives brief relief; follow the product label. Avoid hot, cold or sweet foods and chew on the other side. Pain that lasts needs a dentist within 1 to 2 days even if these steps dull it. Fever, swelling, or difficulty breathing or swallowing means being seen immediately, and by 911 or the ER if breathing or swallowing is affected.
Note — Timing

Frequently Asked Questions About Toothache
My toothache went away overnight. Should I still book an appointment?
It is sensible to. Tooth pain that stops suddenly has not necessarily healed. A nerve that was inflamed can die, which ends the pain for a time while the underlying problem continues and may later turn into an infection. Decay and cracks also cause pain that comes and goes. A dentist can check what was behind it while it is likely still simpler to treat.
Why does tooth pain get worse when I lie down at night?
Lying flat increases blood flow and pressure in the head, and an inflamed nerve inside a tooth has no room to swell, so the throbbing often feels stronger. There are also fewer distractions at night. Propping your head up may ease it. Pain that is strong enough to wake you is a reason to call a dentist promptly, since it often means the nerve is involved.
When is a toothache an emergency instead of something that can wait a day or two?
Persistent pain alone warrants a dental visit within 1 to 2 days. It becomes urgent the same day if you have fever, swelling in the gum, face or jaw, or pain following an injury. Trouble breathing or swallowing, swelling spreading toward the eye or neck, fever with facial swelling, or bleeding that will not stop means calling 911 or going to the ER.
What causes toothache?
Toothache can be caused by: cavities or tooth decay, gum disease, tooth infection or abscess, damaged filling, teeth grinding, erupting or impacted tooth. A dental professional can determine the exact cause through examination.
Is toothache serious?
Toothache should be evaluated by a dentist, though it may not be an emergency. Within 1-2 days for persistent pain. Immediately if accompanied by fever, swelling, or difficulty breathing/swallowing.
Can I treat toothache at home?
Some home remedies may provide temporary relief for toothache, including: over-the-counter pain relievers, taken as directed on the package label, cold compress on cheek, salt water rinse. However, home care is not a substitute for professional treatment.
