Understanding the Type of Infection That Can Lead to a Root Canal

At Shwarts Family Dentistry, we often see patients who are experiencing severe tooth pain and wonder if they may need a root canal. While this procedure is commonly associated with relief from discomfort, the underlying cause of the pain is typically an infection in the tooth’s pulp—the soft tissue inside the tooth containing nerves and blood vessels. But what kind of infection leads to a root canal, and how does it develop?

What Causes a Tooth Infection?

A tooth infection occurs when bacteria penetrate the tooth’s enamel and reach the pulp. This can happen for several reasons, including:

  • Deep Decay: When cavities are left untreated, they can progress through the enamel and dentin, eventually reaching the pulp.
  • Cracks or Chips: A cracked or chipped tooth allows bacteria to bypass the enamel and infect the inside of the tooth.
  • Repeated Dental Procedures: Extensive dental work on the same tooth can weaken it, making it more susceptible to infection.
  • Injury: Trauma to the tooth can damage the pulp even if there are no visible cracks or chips, making it vulnerable to infection.

Signs You May Have a Tooth Infection

An infection in the pulp can be painful and dangerous if left untreated. Signs that you may have an infection include:

  • Severe Toothache: Throbbing or sharp pain, especially when chewing or applying pressure.
  • Sensitivity to Hot or Cold: A prolonged ache when consuming hot or cold foods and drinks.
  • Swelling: Swelling in the gums around the affected tooth, or even in the face or neck.
  • Fever or Fatigue: In some cases, the infection can lead to general illness, including fever and fatigue.
  • Discoloration: The tooth may become discolored due to infection.

Why a Root Canal is Necessary

If the infection reaches the pulp, a root canal is often the best option to save the tooth. During the procedure, the infected pulp is removed, the inside of the tooth is cleaned and disinfected, and the tooth is sealed to prevent further infection. Without this treatment, the infection can spread to other areas of the body, leading to serious health complications.

Preventing Tooth Infections

The best way to prevent a tooth infection—and the need for a root canal—is to maintain good oral hygiene. Brush and floss daily, and visit Shwarts Family Dentistry for regular cleanings and checkups. Catching decay early can prevent it from progressing to the point of infection.
