If a tooth was hurting badly yesterday and feels almost normal today, it is tempting to cancel the dental appointment and move on. Sometimes a brief sensitivity really does settle down. But pain that disappears can also happen when the nerve inside a tooth becomes badly damaged or when an infection changes rather than resolves.
Short answer: If tooth pain was strong, kept returning, woke you up, hurt when you bit down, or came with swelling, do not use the disappearance of pain as proof that the tooth is healthy. A dental exam is the only way to know what changed.
At Arden Mill Family Dentistry in Fort Mill, we see this pattern often: a patient waits because the pain became tolerable, then the tooth flares again at a much less convenient time. The earlier we can identify the cause, the more options there may be to treat the tooth conservatively.
Why can a toothache come and go?
Tooth pain is a symptom, not a diagnosis. The source may be something relatively small, such as exposed root surface or a loose filling, or something that needs prompt treatment, such as deep decay, a crack, inflammation inside the tooth, or an abscess.
The American Association of Endodontists notes that sharp pain while biting can be associated with decay, a loose filling, a crack, or damage to the pulp inside the tooth. Constant severe pain or pressure with swelling may point to an abscess. Just as importantly, an abscessed tooth may or may not be painful.
That is why the pattern matters more than whether you happen to be pain-free at this exact moment.
If the pain stopped, did the nerve die?
It is possible, but you cannot diagnose that from symptoms alone. A tooth contains soft tissue called pulp, which includes nerves and blood vessels. Deep decay, trauma, repeated dental work, or a crack can inflame or infect this tissue.
In some cases, severe pain can lessen when the pulp loses vitality. That does not mean bacteria or infection have disappeared. An untreated infection can continue around the root and surrounding tissues even when the tooth is quieter.
Your dentist may use an exam, X-rays, bite testing, temperature testing, and other findings to determine what is actually happening.
Five signs you should not “wait and see”
Call a dentist (call us at 803-650-6424) promptly if you have any of the following:
Pain that returns repeatedly or lasts more than a day or two.
Pain that wakes you at night or makes it difficult to eat.
Pain when biting or when you release your bite.
Swelling of the gum, face, or jaw; a pimple-like bump on the gum; or a bad taste in the mouth.
A cracked, chipped, or visibly damaged tooth.
Fever, spreading facial swelling, trouble swallowing, trouble breathing, or feeling systemically unwell can signal a more serious infection. Seek urgent medical attention when breathing or swallowing is affected, and contact a dentist immediately for the dental source.
What will the dentist actually do?
The goal of an emergency dental visit is not to assume the worst. It is to find the source.
Depending on what we see, the answer may be as simple as adjusting or replacing a restoration, treating decay, or protecting a cracked tooth. If the pulp is irreversibly inflamed or infected, root canal therapy may be recommended to remove the affected tissue and preserve the natural tooth. If a tooth cannot be predictably restored, extraction may be discussed.
The right treatment depends on the diagnosis. That is also why taking leftover antibiotics without an examination is not a good solution. The American Dental Association recommends dental treatment, rather than antibiotics alone, for most localized pulpal and periapical dental pain. Antibiotics become more relevant when there is systemic involvement such as fever or malaise.
Can I manage the pain at home until my appointment?
If you can safely take them, over-the-counter pain relievers may help temporarily. Follow the package directions and your physician’s advice, especially if you have kidney, liver, bleeding, stomach, cardiovascular, pregnancy, allergy, or medication concerns.
Avoid putting aspirin directly on the tooth or gum. Do not rely on numbing products to delay care for swelling or severe symptoms. If the tooth is cracked, avoid chewing on that side until it is evaluated.
Home measures can make you more comfortable. They cannot tell you whether the underlying problem is getting better.

Frequently asked questions
Can a tooth infection go away on its own?
A dental infection should be evaluated rather than assumed to have resolved because pain improved. Infection around a tooth can persist or progress even when symptoms change.
Why does my tooth hurt only when I bite?
Pain on biting can be associated with decay, a loose restoration, a crack, or inflammation around the tooth. An examination is needed to distinguish among them.
Do I need an emergency dentist if the pain is gone now?
If the earlier pain was severe, recurrent, associated with swelling, or linked to a broken tooth, prompt evaluation is wise even if you feel better today.
Will I automatically need a root canal?
No. Tooth pain has many causes. A root canal is recommended only when the findings show that the pulp is irreversibly inflamed or infected and the tooth can be saved that way.
The safest next step: find out why it hurt
A quiet tooth is not always a healthy tooth. If you have had a significant toothache, a quick diagnosis now can help you avoid being surprised by another flare-up later.
