What causes a root canal to puncture a sinus?
6 doctors weighed in across 3 answers
Sinus: Upper back molar teeth can often have roots which protrude into the maxillary sinus cavity, in the upper jaw and cheekbone. A root canal in an upper back molar tooth could result in a tiny opening into the sinus or filling material in the sinus cavity. If you're concerned about it, return to see the dentist who performed the root canal and discuss it. You may need to see an endodontist.

Overinstrumentation: The canals have a particular 'length" to them. If the clinician was not careful about "working length" and went past the bottom of the tooth, you can "puncture" the sinus. But the instruments are so thin that it really is not a clinical issue and the "puncture" is self healing, very quickly.

RC: If the root is related to the sinus and is infected it may affect the sinus.
