How much pain will I have after a root canal

when should I seek help?

A root canal is a major procedure, so pain is common after a rot canal. A rot canal involves deep cleaning of the inside of your tooth’s canal (inner chamber of the root), which in turn can irritate the surrounding nerves and gums.

Pain doesn’t have to last forever. In fact, a root canal is meant to help you avoid the pain associated with a decayed or cracked tooth. It is normal to experience mild to moderate pain for a few days after a root canal. Any pain beyond this point may warrant additional cleaning of your teeth with canals or other procedures.

Initial recovery period

In the past, root canals were extremely painful. People sometimes avoid such procedures because of this reason.  Dentists now have pain relievers that can be used to reduce the amount of pain you experience during the procedure.

Before the procedure begins, your dentist will apply a local anesthetic that reduces pain. You may still feel pressure during the cleaning, but you should not be in pain during the actual process.

As the local anesthetic wears off after a root canal, you may feel mild pain and sensitivity. It is related to the cleaning process. During the cleaning process, your dentist makes a small opening in the crown of the tooth and cleans out the diseased pulp inside the tooth’s pulp chamber. Uncomfortable, any pain and sensitivity following a root canal should only last a few days.

Since the pain experienced after a root canal is usually mild, you will likely only need relief pain medication. These include acetaminophen (Tylenol) and ibuprofen (Advil, Motrin IB). You’ll want to check with your doctor before taking these medications to make sure they don’t interact with any supplements or prescriptions you’re already taking. You should avoid chewing hard food immediately after the root canal, as this can cause more pain.

When to ask for help

Root canal pain should decrease over time. If you still experience pain or swelling, you should see your dentist. Most people need one to two sessions for a root canal to be successful. In severe cases, you may need more cleaning sessions. Recurrent pain can be an indication of this.

Your symptoms should ease if you are taking any over-the-counter pain medication. If they don’t, your doctor may recommend prescription-strength ibuprofen or narcotic pain relievers. They are only taken on a temporary basis.

Once your tooth is completely healed, your dentist can place a crown on top of it. They can be made of metal, porcelain, or gold. The idea here is to prevent future damage to already fragile teeth. Sometimes pain is a temporary side effect as you get used to the newly placed crown.

Pain management

Pain outside of the root canal should be addressed with your dentist. Aside from temporarily taking medication, there are other things you can do to manage the pain from a root canal. It is important to take care of your teeth, and you should avoid hard and bad foods until your pain improves. Quitting smoking can also help.

You may also consider stress relief activities as a pain management method. Meditation, yoga, and tai chi are all methods that can also take your attention away from your pain.


A successful root canal may cause mild pain for a few days. This is temporary, and should go away on its own as long as you practice good oral hygiene. If the pain persists for more than three days, you should see your dentist.

An alternative to a root canal is a tooth extraction, in which your dentist can replace the damaged tooth with a bridge, partial denture, or implant. This can be an expensive treatment and usually requires several visits to your doctor.

If you are a candidate for a root canal, you will experience less pain over time. According to the American Association of Endodontists, you are six times more likely to be pain free than someone who chooses not to have a root canal.

Tips for oral health

Good oral health practices can help reduce pain from a recent root canal. They can also help your new crown last for many years while protecting all of your other teeth. Consider the following suggestions:

  • Avoid eating hard foods, especially after root canal treatment.
  • Brush your teeth at least twice a day. Make sure to move the toothbrush in gentle circular motions to clean and exfoliate your teeth. You’ll want to take special care around a tooth with a recent root canal.
  • Floss once a day to help prevent future infections.
  • Reduce the amount of sugary foods and drinks you consume.
  • Schedule regular cleanings to help keep your teeth healthy and infection-free.

Do you need a root canal? 7 telltale signs

A root canal is the name of the dental procedure that cleans the decay in the pulp and root of your tooth.

There is an enamel layer on the outside of your teeth, another layer of dentin, and a soft inner core that extends into the root of your jaw. The core consists of the dental pulp, which contains nerves, blood vessels, and connective tissue.

When the lesion penetrates the softcore, the pulp may become inflamed or infected, or even necrotic (dead). A root canal is needed to clean the plant.

So, how do you know if you need a root canal? Are there telltale signs? Keep reading to learn more about the symptoms that indicate you need a root canal.

What is a root canal?

A root canal procedure is like a small roto-rooter, cleaning out decay and saving the affected tooth.

During a root canal procedure, your dentist will:

  • Remove bacteria and decay from the pulp, root and nerves of the tooth
  • Disinfect the area with antibiotics
  • Fill in the blanks
  • Seal the area to prevent new infestations
  • A root canal can be done by your general dentist or a specialist known as an endodontist.

Root canal treatment keeps your natural tooth in place and prevents further decay. But it makes the teeth more fragile. This is why a tooth that has had a root canal is often covered with a crown.

Fast facts about root canal

  • According to the American Association of Endodontists (AAE), more than 15 million root canals are performed in the United States each year.
  • According to the AAE, more than 41,000 root canals are performed every day.
  • Root canal procedures are generally considered the most painful type of dental treatment, but studies show that only 17 percent of people have a root canal, describing it as “the most painful dental procedure.” experience.”
  • A 2016 study found that root canal symptoms vary depending on the type of bacteria in the infection.

Symptoms of root canal

The only way to know for sure if you need a root canal is to visit your dentist. But there are many warning signs to look for.

If you notice any of these symptoms, it is important to see your dentist as soon as possible. The sooner your tooth is treated, the better the outcome will be.

1. Constant pain

Persistent tooth pain is one of the signs that you may need a root canal. Your toothache may bother you all the time, or it may go away from time to time but always return.

You may feel pain in the bone of your tooth. Or you may feel referred pain in your face, jaw, or your other teeth.

Toothache can have other causes besides root canal. Some other possibilities include:

  • gum disease
  • a cave
  • Referred pain from a sinus infection or another problem
  • Damaged filling
  • An infected tooth that can become infected

No matter what the cause is, it’s a good idea to see your dentist if you have a toothache, especially if the pain is persistent. Early diagnosis and treatment of toothache usually results in better results.

2. Sensitivity to heat and cold

Do your teeth hurt when you eat hot food or when you drink a cup of coffee? Or maybe your teeth feel sensitive when you eat ice cream or drink an ice-cold glass of water.


The sensitivity can feel like a dull ache or sharp pain. You may need a root canal if the pain persists for an extended period of time, even when you stop eating or drinking.

If your tooth hurts when you eat or drink something hot or cold, it may indicate that the blood vessels and nerves in your tooth are affected or damaged.

3. Discoloration of teeth

An infection in the pulp of your tooth can cause your teeth to become discolored.

Trauma to the tooth or rupture of the internal tissues can damage the roots and give the tooth a dark-black appearance.

According to Kenneth Rothschild, DDS, FAGD, PLLC, who has 40 years of experience as a general dentist, this discoloration is easier to see in the front teeth. “Tooth pulp can die when the blood supply is inadequate, thus indicating the possible need for a root canal,” explained Rothschild.

Although there can be other causes of tooth discoloration, it is always a good idea to see your dentist if you notice that the color of the tooth is changing.

4. Swollen gums

Swollen gums near a painful tooth can be a sign of a problem that requires a root canal. Inflammation can come and go. It may be tender when you touch it, or it may not be painful to touch.

Rothschild explained that “swelling is caused by acidic waste products of dead pulp tissue, which can cause swelling (edema) outside the root tip area.

You may have a little pimple on your gum. This is called a gum boil, parole, or abscess. Pus comes out from an infection in the tooth. It can give you an unpleasant taste in your mouth and make your breath smell bad.

5. Pain when you eat or brush your teeth

If your tooth is sensitive when you touch it or when you eat, it may indicate severe tooth decay or nerve damage that may require root canal treatment. This is especially the case if the sensitivity persists over time and does not go away when you stop eating.

Rothschild said, “The ligament around the root of the affected tooth can become very sensitive as the pulp dies.” “Extracts from the dying pulp can irritate the ligament, causing pain due to pressure from the bite,” Rothschild said.

6. Cracked or chipped teeth

If you chip or break your tooth in an accident, in a contact sport, or by chewing on something hard, bacteria can set in and cause inflammation and infection.

Even if you injure a tooth, but it is not chipped or broken, the injury can still damage the nerve of the tooth. The nerve can become inflamed and cause pain and sensitivity, which may require root canal treatment.

7. Tooth mobility

When your tooth is infected, it may feel dull.

“It can be caused by other reasons besides pulpal necrosis (nerve death), but it can be a sign that a root canal is necessary,” said Rothschild. “Acidic waste products from nerve death can soften the bone around the root of a dying tooth, causing mobility.”

If more than one tooth feels loose, the mobility is likely to be caused by something other than a problem that requires a root canal.

Does it damage the root canal?

A root canal procedure sounds scary, but with today’s technology, it’s usually not much different than a deep filling. There is little to no pain as your dentist will use local anesthesia to numb your teeth and gums so that you are comfortable during the procedure.

If you need a root canal and have facial swelling or a fever, your dentist may give you antibiotics beforehand to kill the infection. It may help reduce your pain.

The root canal method itself is similar to a large filling, but it will take longer. Your mouth will be empty while the dentist cleans the cavity, disinfects the root, and then fills it in.

Your dentist will use a rubber dam around the root canal tooth. This will help prevent any infected material from spreading to the rest of your mouth.

Your mouth may feel sore or tender after a root canal. Your dentist may suggest that you take an over-the-counter pain reliever such as acetaminophen (Tylenol) or ibuprofen (Advil).

A 2011 review of 72 studies of root canal patients looked at pre-treatment, treatment, and post-treatment pain.

How to prevent a root canal

To prevent root canals, it’s important to follow the same dental hygiene habits that help prevent cavities and other dental problems. To keep your teeth healthy, try to get in the habit of following these steps.

  • Brush your teeth at least twice a day.
  • Floss between your teeth at least once a day.
  • Use fluoride toothpaste or fluoride rinse.
  • See your dentist for a checkup every 6 months.
  • Get your teeth professionally cleaned by your dentist at least once a year.
  • Try to limit the amount of sugar and refined carbohydrates you eat. These foods have a tendency to stick to your teeth. If you eat sugary food, try to wash your mouth or brush your teeth after a while.

The analysis showed that the pain was very high before the treatment, but decreased within a day of the treatment, and then decreased to a minimum level within a week.

Can you still get pain in a tooth that has a root canal?

Yes, it is possible to have pain in a tooth that has had a previous root canal.

Some of the causes of this pain may be:

  • Your root canal is not healing properly
  • Because of the complex root anatomy, your rot canal may not be completely dislodged
  • New decay can affect the root canal filling material, causing new infections
  • A tooth lesion that allows new decay to enter the tooth
  • According to the AAE, retreatment — meaning another rot canal — is the best option for treating pain and other symptoms.

Other questions about root canals

Do you always need a crown if you have a rot canal? Will a root canal be performed by your dentist or an endodontist? We referred these questions to Rothschild.

The bottom line

An infection within the pulp and rot of your tooth can cause discomfort and pain. If you have persistent toothache or other symptoms, see your dentist as soon as possible to get a diagnosis and treatment.

Although the term “rot canal” seems to cause fear in many people, the dental procedure does not involve any particular pain. Almost all people feel better soon after treatment.
