Are Root Canals Safe? A Biological Dentist's Perspective
An Honest Look at a Common Question
Root canal treatment is a well-established way to save an infected tooth. The idea that root canals cause systemic disease comes from the century-old "focal infection" theory, which later research did not support. Research is ongoing on chronic infection at the root tip and its links with conditions such as heart disease, which is why we evaluate each tooth carefully and discuss all your options.
What Research Supports
| Claim or question | Where the evidence stands |
|---|---|
| Root canals are effective at saving infected teeth | Well supported |
| Root-canal-treated teeth cause systemic disease | Based on early 1900s focal infection theory; not supported by later research |
| Chronic infection at the root tip is linked with other conditions | Associations with heart disease and other conditions are reported; causation is not established |
| Leaving an infected tooth untreated is safe | Not supported; infection can spread |
Your Options for an Infected Tooth
| Option | Benefits | Tradeoffs |
|---|---|---|
| Root canal treatment | Saves your natural tooth and bite | Requires a crown in many cases; the tooth needs monitoring |
| Extraction with replacement | Removes the infected tooth entirely | Requires a replacement, such as an implant, bridge, or partial |
| Extraction without replacement | Removes infection at lower initial cost | Can lead to shifting teeth, bite changes, and bone loss |
