A toothache refers to pain in or around your tooth. Minor toothaches can occur from a temporary gum irritation that you can treat at home. More severe toothaches result from cavities, infection or other dental conditions that won’t get better on their own. If you have a severe toothache, you’ll need professional dental treatment.
Causes

Sinusitis – This is a condition in which your sinuses become inflamed due to a viral, bacterial, or fungal infection in your sinus cavity. Because the roots of your upper teeth are close to your sinuses, sinusitis can cause pain in your upper teeth.
Diseases – Heart disease and lung cancer can also cause toothaches. In some cases, toothache may be a warning sign of a heart attack.
Trigeminal neuralgia and occipital neuralgia – are painful neurological conditions that cause your trigeminal and occipital nerves to become irritated or inflamed. These nerves service your skull, face, and teeth. When they become inflamed, pain can feel like it’s coming from your teeth.
Gum disease – This can make your teeth sensitive. Your gums shrink away from your teeth, and that exposes the roots. You also can damage your gums if you brush too hard.
And Finally, There’s no way to know how long your toothache will last. It depends on the underlying cause. For instance, if you have temporary gum irritation, it should go away on its own in a day or two. But if you have a cavity or abscess, the pain may come and go somewhat, but it won’t go away completely. A dentist will perform an examination and ask about your symptoms. They may also take a dental X-ray to see if there are any issues going on beneath your gums.
