When To Worry About A Tooth Infection

Dental Health & Gum Disease : Symptoms of a Root Canal Infection

If you suspect you have a dental abscess, dont wait until it ruptures to seek treatment. Dental infections should be treated promptly to prevent the spread of the infection.

Common symptoms of a dental infection that requires urgent dental care include:

  • Noticeable sore under the gums
  • Swelling and inflammation near the affected tooth
  • Bad taste in the mouth
  • Loose tooth
  • A severe, throbbing toothache that doesnt go away
  • Swollen and painful lymph nodes in the neck
  • Pain when chewing or biting down


Tooth abscesses are dental emergencies. They need to be drained by a professional quickly to prevent spreading. A noticeable sore and severe, throbbing pain are the most common symptoms.

How Long Can a Tooth Infection Go Untreated?

If you wait too long to treat a tooth infection, it can begin spreading to other areas of your body, including the neck, head, or jaw. A general dentist must professionally drain an abscessed tooth by extracting it or performing a root canal.

Usually, this includes draining pus and bacteria, which is why some people are actually unaware they have an infection. It is unpredictable to determine how long a dental abscess will drain until it stops and causes facial cellulitis .

You should never pop or squeeze an abscess because the infection can be pushed deeper into the tissues of your mouth.

Risks of not treating a tooth infection promptly:


General Signs That You Might Need A Root Canal

What are the signs that you may need a root canal to repair an ailing tooth?

At the centre of your teeth, beneath the protective enamel, is a soft pulp known as dental pulp. This pulp extends all the way down to the root of your teeth. This pulp is home to blood vessels, nerves, and connective tissue that can easily be infected when exposed to the outer world. Once a tooth becomes badly damaged , bacteria can sneak into the compromised tooth and enter the pulp.

If the damaged tooth is not repaired quickly, these bacteria can cause an infection that kills the pulp, causes bone loss, and potentially causes the loss of the entire tooth.

Tooth pain alone does not mean you need a root canal. But if there is pain, you should watch for several specific signs of what may be an infection serious enough to require treatment.

Tooth Pulp Root Canals & Infections

All teeth are filled with soft tissue consisting of nerves and blood vessels, also known as pulp. The pulp extends down into the tooths roots in individual channels called root canals. A single tooth has between one and four canals .

When a tooth experiences severe decay that wears through the protective outer layers of the tooth , the bacteria reach the soft pulp inside of it and multiply rapidly. This leads to a worsening infection that can spread all the way down into the root ends and create a pus-filled cyst called an abscess.

Swelling Of Your Gums

Once you undergo a root canal, your gums do swell. However, if it feels like theyre swelling more than usual, thats worrisome. An over swelling or tenderness of your gums when you put pressure on them is one of the signs of root canal infection. Is your swelling still present for an extended period with a pimple forming on the gum? Then you should consult a dentist right away.

How Root Canal Treatment Is Done

3 Symptoms Of Root Canal Infection That Shouldnt Be Ignored

To treat the infection in the root canal, the bacteria need to be removed.

This can be done by either:

  • removing the bacteria from the root canal system
  • removing the tooth

But removing the tooth is not usually recommended as it’s better to keep as many of your natural teeth as possible.

After the bacteria have been removed, the root canal is filled and the tooth sealed with a filling or crown.

In most cases the inflamed tissue near the tooth will heal naturally.

Before having root canal treatment, you’ll usually be given a local anaesthetic.

This means the procedure should be painless and no more unpleasant than having a filling.

Root canal treatment is usually successful. In about 9 out of 10 cases a tooth can survive for up to 10 years after root canal treatment.

Tenderness Or Root Canal Pain

Once you have fully recovered from the root canal procedure itself, the tooth should not remain sensitive. If you feel tooth pain after root canal whenever you apply pressure to the tooth, something has probably gone wrong with your root canal. This problem is normally caused by an inflammation of the surrounding tissues. This inflammation is usually caused by pus and other infectious material leaking out of the tooth.

Dentists use something called a percussion test to check this symptom. Thankfully, this kind of thing is simple enough to perform on yourself. First, watch this video to get an idea of how it works.

As you can see, you will need to begin by examining the tooth with your finger to see if it is tender. If it isnt tender, try biting down on a Q-tip with that tooth. If that doesnt cause any pain or discomfort, you can take a small blunt object and gently tap the tooth. Be very careful here, and use something made of plastic rather than steel just to be on the safe side.

Symptoms Of Lingering Endodontic Problems

When any of the previous circumstances occurs with your root canal tooth, you may experience a range of symptoms. Here are some signs that indicate it may be time to make an appointment with your dental professional, according to the AAE:

  • Sensitivity to hot and cold, or lingering pain after consuming hot or cold food
  • Sharp pain when biting down or when tapping the teeth together
  • Constant pain and pressure
  • Swelling of the gums, with or without the presence of a pimple-like bump near the tooth on the gums
  • A dull ache experienced consistently in the same area

Getting A Root Canal Replacement

Sometimes a root canal procedure does not permanently solve the problem of an abscessed tooth. You may break the tooth long after the root canal therapy, allowing bacteria to enter. A root canal dentist can offer a root canal replacement to help you heal. If you lose pieces of your tooth, your dentist may use a composite resin to rebuild the tooth before adding a root canal crown.

You should be especially concerned if you experience frequent pain with no apparent cause, or if the pain grows steadily worse over time.

How Can A Root Canal Treated Tooth Get Reinfected

Technically, a pulp-less root canal cannot be infected anymore because the infection can only happen on living tissue.

Having said that, a root canal treated tooth is still supported by surrounding living tissue, eg. gum and jawbone. An infection can still happen in two scenarios:

  • If new decay forms around the filling of the root canal treated tooth. When this happens, the fillings defect can allow the bacteria to enter the poorly filled root canal and reach to the tip of the root. From there, the bacteria can start infecting the bone tissue surrounding the root tip . Examples are bacteria remnants in the canal or new cavity forms under the tooth filling. You can click here to read more about Why Do Teeth Decay Under Fillings.
  • If the bacteria have already existed in the bone tissue before the root canal treatment is done. In this case, root canal treatment will not be able to remove those bacteria as they reside outside the root canal .
  • To suggest an analogy, a decorative plant will not be damaged by bugs. However, the bugs could still invade the soil supporting the plant, giving trouble to you.
