Root Canal Infections: Testing for Hidden Bacteria in Dentistry

The Silent Threat

Root canal–treated teeth can harbor hidden infections. These infections may not cause immediate pain but can release harmful bacteria into the bloodstream. At Amore Dentistry, we use advanced testing to detect pathogens and guide safer treatment decisions.

Why Standard Root Canal Tests Fall Short

• Conventional x-rays often miss lingering infection.

• Biofilm inside root canals can hide pathogens.

• Symptoms may appear years later, linked to systemic illness (Siqueira & Rôças, 2009).

Modern Microbiological Testing

• PCR (polymerase chain reaction) identifies bacterial DNA.

• DNA Connexions® testing reveals specific organisms.

• Common culprits include Enterococcus faecalis, Fusobacterium, and spirochetes.

Holistic Options for Infected Root Canals

• Extraction with guided bone healing.

• PRF/ozone to disinfect surgical sites.

• Biocompatible restorations instead of metals.

Know Before You Decide

Testing infected root canals empowers patients to make informed, holistic choices about their dental and systemic health.
