When you have a toothache that won’t quit or a tooth with visible damage, and your dentist recommends a root canal procedure, you probably have questions. What is a root canal procedure, and what is my appointment going to look like?
Root canals are procedures that enable a dentist to access, clean, and repair damaged areas of a tooth to prevent bacteria and infection from spreading. This treatment makes it more likely that the tooth can be saved and addresses the pain and sensitivity in the affected area.
Here’s what you can expect during a root canal appointment, including how the procedure may vary and why some treatments require more than one visit.
How Long Is a Root Canal Appointment?
One of the first things patients want to know is how long does a root canal take?
Root canal appointments can vary depending on the nature of the issue. Typically, a root canal is completed in one or two sessions. These last anywhere from around an hour and a half to a few hours1. The dentist will walk you through the expected timeframe for your situation.
Root canal appointments take time because they require multiple steps. First, the dentist will numb the location near the tooth with an anesthetic and prepare the area with a dental dam. Then, they will create a small hole in the tooth to access and remove the infected pulp before cleaning inside the tooth2.
Once ready, the dentist will fill the prepped, hollowed area in the tooth with a dental material called gutta-percha and use an adhesive to seal the tooth. The tooth will become more brittle over time, so the dentist will place a crown to protect it. This can be done in the same visit but often requires a follow-up1.
Single vs. Multi-Visit Root Canals
A root canal may be completed in a single visit or multiple visits, depending on the severity of the situation. More complicated cases, such as the presence of lesions, may require multiple visits. Your dentist may also put a crown on your tooth in a follow-up appointment, so you have time to recover from the initial procedure.
Both approaches have their advantages and disadvantages. A single visit means fewer trips to the dentist, reduced gum irritation, and less opportunity for infection or contamination in between visits. However, a multi-day root canal may be more appropriate to ensure the area is completely sterilized before resealing the tooth3.
What Affects the Timeline?
Every patient’s oral health varies, which can impact the length of the procedure. The type of tooth receiving the root canal also plays a role because larger teeth with more pulp canals require more time and work.
Your front canine and incisor teeth only have a single canal. However, molars at the back of the mouth have several canals. This means root canals on molars typically take longer than those on incisors because each canal needs to be cleaned out, sterilized, and filled.
Since root canal times can vary, it’s best to plan for an appointment lasting at least 90 minutes while being aware that this can vary. Your dentist will talk through which of your teeth require treatment and the estimated timing.
The dentist may also want to allow time for the tooth to heal before adding a crown, which will add another visit to the overall timeline4.
What to Expect From Recovery Time
How painful is a root canal? The truth is that recovering from a root canal is relatively quick.
Typically, patients can expect to recover within a week with proper oral care. Regular brushing and flossing help prevent infections and protect the teeth and gums. The dentist may also recommend rinsing with salt water to reduce the risk of infection during recovery4.
Eating softer foods, such as yogurt, soups, smoothies, and pasta prevents you from putting excess pressure on the treatment area2. Avoid harmful habits, such as smoking, and chewing hard foods.
Your dentist or endodontist may prescribe a pain reliever or recommend over-the-counter options after a root canal to help manage discomfort4. It’s essential to follow their directions to help with recovery. If you experience persistent pain after the procedure, reach out to your dentist for guidance.

Frequently Asked Questions
Can a root canal be done in one visit?
It is possible to complete a root canal procedure in one appointment. However, it’s also typical for a root canal to require multiple visits to the dentist. The difference will depend on the overall health of the patient’s tooth and whether there are additional complications that need to be addressed or multiple teeth that require work.
Teeth that have root canals typically receive a crown as well for protection. The dentist may want to do this during a separate appointment, so the treated tooth has time to recover. In this case, most of the procedure is completed in one visit, but you’ll still need to come in again for a shorter visit.
The best way to learn whether you need a tooth canal and how many visits the treatment is likely to take is to schedule a consultation with Beam Dental.
How long until I can eat normally?
Patients can usually start eating within a couple of hours of the root canal, as long as the anesthetic has worn off. However, the dentist will likely recommend avoiding certain foods while your teeth and gums heal.
Following the appointment, it’s best to stick to softer foods and liquids, like soups and smoothies, for a few days. Avoid hard and sticky foods that may damage or irritate your mouth.
Does it hurt after the procedure?
It’s normal to feel for a few hours after the procedure and some discomfort for a few days after. You may also experience swelling around the tooth. Pain that lasts more than a week is worth a follow-up with the dentist.
Your dentist may recommend over-the-counter painkillers or prescribe one to help manage these symptoms after the procedure.
Good hygiene can also help reduce discomfort. Brushing and flossing keep bacteria away from sensitive teeth, and avoiding tough foods and smoking helps prevent irritation.
