Our Standard of Care

Why the Details Matter

Rubber dam — always

No exceptions. Rubber dam isolation is a non-negotiable standard of care for every root canal at our office. It protects you and protects the outcome.

Electronic apex locator + X-ray

Dr. Nail uses both an electronic apex locator and a working length radiograph to confirm working length — not one or the other. Dual verification means greater accuracy.

NiTi rotary instrumentation

Flexible nickel-titanium rotary files follow the natural curve of your canals without distorting them — a significant advantage over older stainless steel hand files.

MTA sealer — not ZOE

Dr. Nail uses modern calcium silicate (MTA-based) sealer rather than older zinc oxide eugenol formulations. Better biocompatibility, better seal, better long-term outcomes.

Thorough irrigation protocol

Alternating NaOCl and EDTA irrigation removes bacteria and the smear layer from the full length of the canal — including lateral canals that files cannot reach.

Final X-ray verification

Every root canal ends with a final radiograph confirming the fill is complete, dense, and at the correct length. No guesswork — documented proof of a quality result.
