how long does a root canal procedure take

Most routine root canals take about 30–90 minutes of chair time, with more complex cases sometimes lasting up to 2 hours and occasionally being split over two visits.

Quick Scoop

• Simple tooth (like a front tooth with one canal): often 30–60 minutes in a single visit.

• More complex tooth (like a molar with several canals): roughly 60–120 minutes, sometimes closer to 90 minutes or a bit more.

• Number of visits: many dentists finish in one visit, but some cases are scheduled over two (or more) shorter visits, especially if the infection is severe or the tooth has tricky anatomy.

• Extra time: if you also need a crown afterward, that’s usually a separate appointment of about an hour.

What Affects How Long It Takes?

• Which tooth is treated (front teeth are simpler, molars more complex).

• How many root canals the tooth has and how curved or narrow they are.

• How bad the infection or damage is and whether it’s a first-time treatment or a retreatment (re-do usually takes longer).

• Whether your dentist does it in a single longer visit or prefers multiple shorter ones.

Simple Timeline Example (One Visit)

• Numbing and setup: about 10–20 minutes.
• Cleaning and shaping the canals: about 30–60 minutes, longer for molars.

• Filling and sealing the tooth: about 10–20 minutes.

So, if you’re planning your day, it’s wise to block about 1.5 to 2 hours for the appointment, even though the actual work on the tooth is often closer to an hour for straightforward cases.
