What can cause this pain?

Toothache has several recognised causes, including decay, a dental abscess, a cracked or damaged tooth, a loose or broken filling, gum disease, grinding, braces, and sensitivity.

Possible causes to discuss
Possible causeWhat to tell the dentist
Tooth decaySay when the pain began and whether a sweet or hot trigger brings it on[2]
Toothache from another dental problemDescribe the exact site, intensity, and whether the pain is spontaneous[2]
Crown-related problemSay whether the crown is loose, damaged, or uncomfortable when biting[2]

[2]

What relief is safe tonight?

Avoid the trigger while the tooth hurts and take pain medicine only according to its label. Temporary relief does not treat the dental problem causing the pain.

[2][3]

How will a dentist diagnose it?

The history records where the pain is, how long it lasts, and whether heat, cold, sweet food or drink, chewing, or brushing brings it on. Examination and dental radiographs help assess the tooth.

[1][2]

What treatment depends on the cause?

The treatment follows the cause: decay, a damaged tooth, a filling problem, gum disease, grinding, or a dental infection each needs its own dental treatment. Root canal treatment is used when the pulp needs it.

[2][3]

How can you reduce the chance of it returning?

Brush with fluoride toothpaste twice a day for about two minutes, clean between your teeth daily, limit sugary foods and drinks to occasional treats at mealtimes, and attend regular check-ups.

[1][2]

When should you seek dental care?

Get dental care when toothache lasts more than two days or does not settle with painkillers. Fever, pain on biting, red gums, a bad taste, or cheek or jaw swelling need prompt dental attention.
