Dental problems can occur to people of any age, and it should not be taken lightly. If you are practicing good oral hygiene practices and a regular visit to the dentist, you can relatively prevent the problems easily. However, you should wait to consult your dentist while facing any type of tooth pain. 

Here we are focusing on one of the serious dental problems called ‘hot tooth’.

What is a hot tooth?

The term ‘hot tooth’ refers to a condition of the inflamed tooth pulp. It can occur due to extensive tooth decay, gum disease, or leaking old filling. The hot tooth is irreversible pulpitis, pointing to spontaneous severe, or moderate pain. Sometimes the hot tooth pain is unbearable, and a patient visits a dentist clinic in an emergency. 

The hot tooth syndrome develops when the pulp’s chronic inflammation progresses into an acute flare-up. During this acute pulp infection, the blood vessels dilate their permeability, enabling the plasma proteins to escape the blood and enter into the connective tissue spaces outside the capillaries. This results in edema and intensified pressure on the nerve fibers. As a result, the discomfort and pain of the affected area start. The hot tooth’s impact is more visible if the tooth has an amalgam (silver) or gold restoration as the metals are good thermal conductors. 

The most common sites of hot tooth occurrence include:

  • Primary and permanent teeth 
  • Sites of recent or defective restorations
  • Sites of recent trauma

Symptoms of hot tooth

A hot tooth generally occurs because of the infection, and it shows the following symptoms along with a moderate to severe pain:

  • Tooth sensitivity (to hot and cold food)
  • Toothache
  • Sensitivity to sweet food
  • Inflammation
  • Swelling on the site
  • Bad breath
  • Fever (if the inflammation is severe)
  • Bad taste in the mouth

Causes of hot tooth

Enamel and dentin layers protect the pulp from any infection. When the protective layers are damaged, the bacteria get into the pulp, causing the condition (hot tooth). As the pulp resides trapped inside the tooth’s walls, the swelling causes pressure, pain, and infection.

The layers (enamel and dentin) can be damaged by varied conditions such as:

  • Tooth decay or cavities
  • Fractured tooth 
  • Tooth or facial injury

Besides, prolonged poor oral hygiene may cause major dental problems, including a hot tooth.

In the case of a hot tooth, it’s not actually the tooth but the nerves that cause a lot of pain.

Even the smallest thing can send a lot of pain.
