Understanding Root Canal Infections

Inside every tooth, beneath the white enamel and hard dentin, there’s a soft tissue called pulp. This pulp contains:
• Blood vessels
• Nerves
• Connective tissue

If bacteria get inside the tooth and infect the pulp, you have a root canal infection.

What Causes a Root Canal Infection?
A root canal infection happens when bacteria invade the pulp. This can be caused by:
• Tooth decay (cavities that reach the pulp)
• A crack or chip in the tooth
• A fractured tooth root
• Repeated dental procedures
• Injury to the pulp (even if the outside looks fine)

Root canal infections can develop without symptoms, so early detection is key!

What Happens if You Ignore a Root Canal Infection?
A root canal infection won’t go away on its own. If left untreated, it can lead to:
• Severe tooth damage – The infection spreads, destroying the tooth structure.
• Tooth loss – Extraction may be needed if too much of the tooth is damaged.
• Shifting teeth & bite problems – Missing a tooth can cause teeth to move out of place.
• Jawbone loss – Without a tooth, the jawbone in that area starts shrinking.
• Serious health risks – The infection can spread to the bloodstream, leading to sepsis, bone infections, or even heart problems.

Watch out for these symptoms:
• Persistent tooth pain
• Sensitivity to hot and cold
• Swollen gums or jaw
• Pimple-like bump on the gums
• Tooth discoloration
• Cracked, chipped, or loose tooth
• Pain when chewing or applying pressure

How is a Root Canal Infection Treated?

Standard Root Canal Treatment (RCT)

  1. X-rays are taken to check the infection.

  2. Local anesthesia is applied to numb the area.

  3. A small opening is made in the tooth to remove the infected pulp.

  4. The inside of the tooth is cleaned, shaped, and sealed.

  5. A temporary filling is placed until the final crown is added.
