How to know if you need a root canal: Symptoms and solutions

28/04/2025

Dental pain is one of the most common discomforts and can be a symptom of various oral health problems. In some cases, it may indicate that the tooth pulp is inflamed or infected, requiring a root canal treatment to avoid extracting the affected tooth.

If you have ever wondered how to know if you need a root canal, this article will help you identify the symptoms to watch for and the available solutions to preserve your tooth. At Clínica Dental Dr Lluch, we have a team of endodontic specialists who will provide you with the best care to maintain your oral health.

What is a Root Canal and When is it Necessary?

Endodontics, also known as root canal treatment, is a dental procedure performed when the tooth pulp is damaged due to deep decay, trauma, or infection.

The dental pulp is the soft tissue inside the tooth that contains nerves and blood vessels. When it becomes inflamed or infected, it can cause intense pain, and if not treated in time, the infection can spread to the surrounding bone and tissues, compromising the health of the tooth and the mouth overall.

Root canal treatment removes the damaged pulp, cleans and disinfects the inside of the tooth, and seals it to prevent future infections. This treatment is an effective alternative to extraction as it allows for the conservation of the natural tooth and its functionality.

Symptoms That Indicate You Need a Root Canal

While pain is the most common symptom of a pulp infection, there are other signs that may indicate the need for a root canal treatment.

Persistent or Severe Dental Pain

One of the main signs that a root canal is necessary is continuous pain in a tooth, which may intensify when chewing or applying pressure. This pain can be intermittent or constant and, in some cases, does not go away with painkillers.

If you experience persistent discomfort, especially when eating, it is advisable to visit the dentist as soon as possible to prevent the infection from worsening.

Excessive Sensitivity to Heat and Cold

Dental sensitivity is normal to some extent, but when it persists even after the stimulus (such as cold or hot foods) is removed, it may indicate pulp damage.

If you feel sharp, prolonged pain after consuming hot or cold beverages, it is a sign that something is wrong inside the tooth.

Swelling and Redness of the Gums

Swollen, red, or tender gums around a tooth may indicate an infection in the root. In some cases, a dental abscess may form, which is a buildup of pus caused by a bacterial infection.

If you notice abnormal swelling in the gums, especially if accompanied by pain, it is essential to consult a specialist.

Darkening of the Tooth

When a tooth changes color and darkens, it may be a sign that the dental pulp is dead or undergoing necrosis. This darkening occurs due to the lack of blood supply to the tooth and is a clear indication that a root canal may be necessary.

Appearance of Fistulas or Abscesses

Dental fistulas are small bumps on the gums that may drain pus and are a clear sign of an internal tooth infection. These lesions may temporarily disappear, but if the infection is not treated, the problem will persist and worsen over time.

If you experience any of these symptoms, it is best to visit a dentist for a proper evaluation and diagnosis.

Why is it Important to Perform a Root Canal on Time?

When the dental pulp is infected, the problem does not resolve on its own. Without proper treatment, the infection can spread to surrounding tissues, causing more serious issues, such as:

  • Loss of the affected tooth.
  • Infections in the jawbone.
  • Spread of bacteria into the bloodstream, affecting overall health.

Timely root canal treatment prevents complications and allows the natural tooth to be preserved, which is key to maintaining good oral health and avoiding more invasive treatments in the future.

What is the Root Canal Procedure Like?

Root canal treatment is a safe and effective procedure carried out in several stages:

 Evaluation and Diagnosis

The dentist examines the tooth and takes X-rays to assess the extent of damage to the pulp and root canals.

 Application of Local Anesthesia

To ensure the procedure is painless, local anesthesia is applied to the affected area.

 Removal of the Damaged Pulp

A small opening is made in the tooth to access the pulp and remove the damaged tissue.

 Cleaning and Disinfection

The root canals are cleaned and disinfected to remove any bacteria present.

 Sealing of the Root Canal

Once clean, the canal is sealed with a special material to prevent future infections.

 Restoration of the Tooth

Depending on the damage, the tooth may require a reconstruction with a filling or a dental crown to restore its function and appearance.

How Long Does a Root Canal Treated Tooth Last?

A tooth treated with a root canal can last many years, even a lifetime, provided good oral hygiene is maintained and regular check-ups are performed.

To ensure the durability of the tooth, it is advisable to:

  • Maintain good oral hygiene with brushing and flossing.
  • Avoid chewing very hard foods in the treated area.
  • Attend regular dental check-ups to monitor the health of the treated tooth.
