The Ultimate Guide to Understanding the Meaning of Root Canal

The term “root canal” refers to both a dental procedure and a part of the tooth. It involves the removal of infected or damaged tissue within the tooth’s canal, aiming to save a tooth from extraction. This treatment addresses severe tooth decay or infection, alleviating pain and restoring oral health. Understanding the meaning of root canal is crucial for individuals seeking relief from tooth-related discomfort and preserving their natural teeth.

What is a root canal?

The procedure known as a root canal involves the extraction of the tooth’s pulp, which consists of nerves, connective tissue, and blood vessels. Typically, a general dentist or endodontist will administer local anesthesia before performing this procedure. Find out more about this commonly performed treatment and the possible risks associated with it.

When is a root canal needed?

When the soft inner part of a tooth, known as the pulp, becomes inflamed, injured, or infected, a root canal is necessary. Although the crown of the tooth may remain intact, removing the damaged pulp is the best way to preserve the tooth’s structure. 

The pulp can become damaged due to untreated cavities, multiple dental procedures on the same tooth, a chip or crack in the tooth, or an injury to the tooth. 

Common symptoms of damaged pulp include pain in the tooth, swelling, and a sensation of heat in the gums. To confirm the diagnosis, the dentist will examine the painful tooth and take X-rays. If a root canal is needed, the dentist may refer the patient to an endodontist.

How is a root canal performed?

In a dental office, a root canal procedure is carried out. Upon your arrival for the appointment, a technician will accompany you to a treatment room, assist you in getting settled in a chair, and place a bib around your neck to shield your clothes from stains.

Step 1: Anesthetic Application

The dentist administers numbing medication on the gum adjacent to the affected tooth. Following this, a local anesthetic is injected into the gums. While you may experience a brief sharp sensation or slight burning initially, this discomfort swiftly dissipates. Throughout the procedure, you will remain conscious, yet the anesthetic ensures you won’t feel any pain.

Step 2: Pulp Removal

Once the tooth is numb, the endodontist or general dentist creates a small opening at the top of the tooth. With specialized instruments called files, the infected or damaged pulp is meticulously removed. Thorough cleaning of the tooth’s canals is undertaken to ensure complete removal of the affected tissue.

Step 3: Antibiotic Application

After the pulp extraction, a topical antibiotic may be applied to the area to eradicate any remaining infection and prevent reoccurrence. Subsequently, the cleaned and disinfected canals are sealed with gutta-percha, a rubber-like material, and a sealing paste. Additionally, oral antibiotics may be prescribed for further infection control.

Step 4: Temporary Filling

To conclude the procedure, a soft temporary filling material is used to seal the small opening at the tooth’s top. This temporary sealant serves to safeguard the canals from potential damage caused by saliva.
