Most patients get mild symptoms, if any. One comparative study of 168 root canal patients in the International Endodontic Journal cited a pain level hovering just above one on a zero-to-10 scale. Researchers noted that 63% of participants recorded no anterior pain at all.
For many patients, getting a root canal is no more painful than getting a cavity filled thanks to the use of local anesthetic and modern endodontic techniques. Most people report feeling comfortable throughout their procedure, feeling pressure and movement at times, but not pain.
Is the second visit for a root canal painful? Not at all. During this visit, you have just completed a course of antibiotics, and your dentist has removed most of the infection within the tooth structure.
Though no more painful than getting a filling done for a cavity, many people fear getting a root canal because they've heard that they are painful. In reality, the most painful part of a root canal is the pain you are experiencing before the procedure is performed.
Is a root canal painful? Since patients are given anesthesia, a root canal isn't more painful than a regular dental procedure, such as a filling or getting a wisdom tooth removed. However, a root canal is generally a bit sore or numb after the procedure, and can even cause mild discomfort for a few days.
Root canal pain has a reputation for being unbearable or extremely painful, but this type of discomfort is not normal. Instead, those who undergo root canal procedures can expect mild to moderate discomfort during and after the procedure without the pain becoming too bad.
Root canals can be a painful procedure. In fact, many find it to be more painful than an extraction, but the use of local anesthesia can reduce the pain.
Fillings and root canals share symptoms such as pain, toothaches, swelling, sensitivity to extreme temperatures, and visible damage to teeth. The difference between the two is that if a root canal system is damaged and infected, the severity of symptoms will be much higher.
Root canals are considered to be the most painful because they require removing the nerve tissue on a tooth's root. The removal of the nerve tissue is not only excruciatingly painful but also commonly leads to infection.
The maxillary molars, especially the second molars, have the most complicated root canal system in permanent dentition. There are many variations in canal number and configuration in maxillary molars. Treatment may be unsuccessful because the dentist may fail to recognize the unusual canal configuration.
The root canal procedure is completed in two separate visits to ensure that the tooth is thoroughly cleaned out, sealed up, and protected from further damage.
Can I Brush My Teeth After a Root Canal? The short answer is yes! It's very rare that any dentist will instruct you to not brush your teeth after a dental procedure. Once the numbing medication has completely worn off, you are free to brush your teeth as you normally would.
Depending on the amount of infection in your tooth, root canal therapy may require one or two appointments. On average, a root canal takes about 30 to 60 minutes to complete. If you are having treatment on a larger tooth with multiple roots, it can take up to an hour and a half.
The intensity of tooth pain can be extraordinary, with severity rivaling true neuralgia – intense neurological pain of almost unparalleled proportions. So, why do toothaches hurt so much? Here's why: That painful tooth is literally in your head.

It has been generally accepted that mandibular molars are the most difficult teeth to anaesthetise, especially if irreversible pulpitis is present (1, 8).
Although a tooth that is treated in a root canal are weakened by decay and by treatment, they are also reinforced so they're usually strong enough to last for a long time, possibly decades.
Infection and abscess.
If you let a root canal sit for long enough, you'll likely get infected gums and even tooth abscesses. These are painful and can have lasting health complications in your mouth and throughout your body.
The need for a crown is typically determined by the amount of remaining tooth structure after a root canal. Generally, if more than half of the tooth is gone, a crown is indicated to restore the tooth's structural integrity.
Root Canals Aren't Possible with Severe Infection
If the deepest layers of the pulp become infected, it may be too late to save the tooth. In addition, if a large portion of the tooth is lost and a crown cannot be placed on what's left, root canal treatment is no longer a viable solution.
Tooth infections are severe and generally need people to be treated with antibiotics before proceeding with the removal. In such cases, dentists prefer performing endodontic therapy to preserve the tooth. However, if the tooth's internal structure is affected, the only alternative available is to extract the tooth.
In most cases, root canal therapy is a better way to treat an infected tooth than an extraction. However, there are exceptions, such as if the tooth has suffered extreme damage. Your dentist will carefully analyze your oral health before making a treatment recommendation.
After your final treatment, your restored tooth should no longer be painful, although it may feel sore for a few days. You can take over-the-counter painkillers, such as paracetamol or ibuprofen, to relieve any discomfort.
Swelling may increase 48-72 hours before diminishing. Swelling may be worse in the morning and usually subsides as the day continues. Slight bleeding or oozing may discolor saliva up to 24 hours after surgery. This is normal.
