What Are the Main Reasons for A Toothache?


Toothache is a severe pain around the tooth that may be caused by various distinct factors. The nerve and blood tissues found in the interior layer of the tooth, known as the pulp, keep our teeth alive and functional. Our body is usually formed so that it is adapted to perceive different types of sensations based on the type of nerve endings present in different tissues.

Tooth Decay

The prime reason for a toothache is tooth decay or a cavity that can cause a mild to sharp pain when biting down or eating something sweet or acidic. It is important to see your dentist and get a filling before the cavity causes more severe problems.


Another major reason for toothache is an abscess or an infection that can cause throbbing pain as a result of an untreated cavity, injury, or dental work. An abscess associated with a fever typically requires antibiotics and drainage, and your dentist or endodontist will complete a root canal.

Tooth Sensitivity

Tooth sensitivity is the other problem that lasts only moments when teeth come in contact with liquids, cold air, and food is likely due to receding gums or thinning of the tooth enamel. It is suggested by professional experts to switch to fluoride-containing toothpaste for sensitive teeth and a soft-bristled toothbrush.

Tooth Injury

Tooth injury like a chipped tooth from biting onto something hard can further lead to pain when biting or chewing, as well as sensitivity to hot, cold, sour, or sweet food. It is important to contact the doctor immediately for an emergency visit before the pain worsens.

Wisdom Teeth

Wisdom teeth can also cause pain when they are impacted or fail to break by the gumline. This typically causes inflammation of the gums, but pain may extend to the jaw and the ear. Take over-the-counter pain medication or see your dentist for a wisdom tooth removal.

All the dental specialists suggest having a routine checkup as and when you feel any discomfort or pain in your teeth or jaw so proper treatment can be administered. Leaving pain unprocessed can cause more severe, life-threatening issues to develop. There are multiple reasons for your nagging toothache, but by practising proper hygiene, avoiding nasty habits like teeth grinding, and scheduling regular visits to your dentist, any toothache can be fixed.
