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. Illustration: Cross-section of a tooth showing enamel, dentin, and infected pulp.

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! Illustration: Different causes of root canal infections.

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. Illustration: Timeline showing the progression of an untreated root canal infection.

Signs You Might Have a Root Canal Infection

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 Illustration: Checklist of symptoms associated with root canal infections.

How is a Root Canal Infection Treated?

Standard Root Canal Treatment (RCT)

X-rays are taken to check the infection.

Local anesthesia is applied to numb the area.

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

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

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

A Modern Alternative: The GentleWave® Procedure

The GentleWave® Procedure is a newer, advanced treatment that:

• Uses less drilling and filing, preserving more of the natural tooth

• Reduces post-treatment pain

• Promotes faster healing

• Can often be completed in one visit! Illustration: Comparison of traditional root canal vs. GentleWave® Procedure.
