A root canal isn't as painful as its reputation suggests; modern dentistry uses strong anesthesia, making the procedure feel like a routine filling with mild pressure, while the treatment actually relieves the severe pain from an infected tooth. You might feel some soreness or mild discomfort for a few days afterward, manageable with over-the-counter pain relievers, but persistent or throbbing pain means you should see your dentist.
Myth 1: Root canal treatment is painful.
That may have been the case decades ago, but with modern technology and anesthetics, you won't experience any more pain than if you went to have a cavity filled.
A root canal procedure generally takes between 30 and 90+ minutes. It can also depend on what tooth you need a root canal on. Some teeth are easier to clean out because they have fewer roots, such as your canine teeth.
Most patients feel no pain during the procedure, only slight pressure or vibrations. After the procedure, mild discomfort or soreness may occur as the tissue around the treated tooth heals. On a pain scale of 1 to 10, post-procedure pain is usually around 2-3/10, comparable to mild soreness after a dental filling.
The most painful part of a root canal is often the pain you feel before the procedure begins.
Most root canals take about 60 to 90 minutes. Some may require more than one visit.
The 3-3-3 rule for toothache is a temporary pain management strategy: take 3 ibuprofen (200mg each) three times a day for 3 days, but 3 hours apart (or every 8 hours), to reduce inflammation and pain until you can see a dentist; it's crucial to consult a doctor first, especially with underlying conditions, as it's not a cure but a short-term fix for inflammation.
Your $3,000 root canal cost reflects the procedure's complexity, often involving back teeth (molars) with multiple roots, the need for a crown afterward, the specialist's expertise, advanced equipment, and the time-intensive nature of cleaning and sealing the infected pulp, with costs varying by tooth location, complexity, and materials used.
Root canals are often portrayed as the epitome of dental pain. However, modern techniques and anesthesia have made them much more tolerable. During a root canal, your dentist removes infected tissue from within a tooth. The discomfort usually comes from the infection itself, more so than the procedure.
Molars are large, flat teeth located at the back of your mouth. They are primarily used for grinding and crushing food. Molar root canals are usually more difficult than incisors because they have more roots and require specialized instruments to access them.
If you've recently undergone or are about to undergo root canal therapy, one of the most common concerns is “How long does it take to recover from a root canal?” The typical root canal recovery time is between 2–7 days, depending on the individual case and how well you follow your dentist's aftercare instructions.
The second visit is crucial for completing the root canal procedure and restoring the tooth's functionality and appearance. During this appointment, the dentist removes the temporary filling, thoroughly cleans the root canal, and fills it with a biocompatible material called gutta-percha.
Amount of natural tooth structure remaining
The more natural teeth you have left after your root canal, the better your options become. Teeth with substantial remaining structure might survive with just a filling, while those with minimal tooth left almost always need crown protection.
#1 Bring Headphones
If it's hard for you to stay calm amidst sounds of scraping and drilling, you're not alone. We encourage our patients to bring their phone or another device and a pair of headphones so they can listen to their favorite music or podcast during their root canal and tune out from all the dental noises.
When presented with both options of Root Canal vs Extraction, more often than not, opting for a root canal will be less expensive and allow you to keep your tooth. Nothing looks, feels or functions like a natural tooth. Finally, an extraction is a larger procedure and often is more uncomfortable than a root canal.
8 Signs That You Might Need a Root Canal
The "3-3-3 dental rule" usually refers to two different things: a hygiene habit (brush 3x a day, 3 mins each, change brush every 3 months) or a temporary pain relief method for toothaches (3 ibuprofen tablets, 3 times a day, for 3 days). The hygiene rule promotes better cleaning, while the pain rule manages inflammation until a dentist can be seen, but the medication rule requires caution and should be discussed with a doctor.
Pain During the Procedure
During the root canal itself, the pain is often minimal, ranging from a 0 to 3 on the pain scale. Thanks to effective anesthesia, most patients feel little more than pressure as the dentist works.
Commonly “Feared” Dental Procedures
It's necessary to have endodontic or root canal treatment when the inside of your tooth (the pulp) becomes inflamed or infected as a result of deep decay, repeated dental procedures, faulty crowns or a crack or chip in the tooth.
The average cost for a root canal in Australia ranges from approximately $900 to $3,400 (AUD) for the procedure itself, excluding the often-needed dental crown, with front teeth being cheaper and molars more expensive due to complexity. A crown can add another $1,500 to $3,000+, making the total often between $2,000 to over $5,000. Costs vary by tooth type (front vs. molar), infection severity, the dentist's specialization (general dentist vs. endodontist), and extra imaging like CBCT scans.
A root canal is designed to save your natural tooth and relieve pain, but like any medical procedure, success isn't always a guarantee. While most root canal treatments are highly effective, some may fail because of hidden infections, untreated canals, or cracks within the tooth.
The ER can provide temporary relief for severe tooth pain by offering strong pain medication and antibiotics for infections, and draining abscesses, but they can't fix the underlying dental problem, so they'll refer you to a dentist for permanent solutions like fillings or extractions. Go to the ER for severe pain with swelling, fever, or facial trauma, but know they're managing symptoms, not the cause.
The timeline depends on the cause and severity of damage. For minor decay, the nerve may take weeks to die. For severe trauma or infection, it could die within days.
