Root Canal Treatment (Endodontics) in Vanak, Tehran

Root canal treatment (endodontics) is one of the most effective ways to save infected and damaged teeth, preserving the tooth rather than extracting it. At the practice of Dr. Zahra Sadat Shamekhi, a DHA-licensed general dentist practising since 2013 in Vanak, Tehran, root canal treatment is performed under complete anaesthesia, with high precision and strict sterilisation, so that your pain is relieved and your natural tooth is preserved.

Severe pain when chewing, prolonged sensitivity to hot and cold, gum swelling or darkening of a tooth can all indicate the need for a root canal. Below you will learn what root canal treatment involves, its benefits, the treatment steps and the role of a crown afterwards.

What is a root canal?

At the centre of every tooth is a soft tissue called the "pulp", which contains the nerve and blood vessels. When this tissue becomes infected or inflamed due to deep decay, a crack or trauma, it causes pain and, if left untreated, leads to an abscess and bone loss. During a root canal, the damaged pulp is removed, the root canals are disinfected and filled, and the tooth is preserved — healthy and functional — without its nerve.

Signs you may need root canal treatment

• Spontaneous or throbbing pain: especially at night or while chewing.
• Prolonged sensitivity: pain that lingers after contact with hot or cold.
• Gum swelling and abscess: a swelling or pus-filled bump near the root.
• Tooth darkening: discolouration caused by death of the internal tissue.

Benefits of root canal treatment

By saving the tooth instead of extracting it, root canal treatment preserves the health and natural function of your mouth. Its most important benefits include:

• Definitive relief from pain and infection
• Preservation of the natural tooth instead of extraction and implant placement
• Prevention of the infection spreading to the bone and neighbouring teeth
• Restoration of chewing ability and preservation of a beautiful smile

The root canal procedure

At Dr. Shamekhi's practice the root canal process is precise, sterile and completely painless:

1. 01. Examination, radiography and complete local anaesthesia of the area
2. 02. Creating the access cavity and removing the infected pulp
3. 03. Irrigation, disinfection and shaping of the root canals
4. 04. Filling the canals, restoring the tooth and, if needed, placing a crown

A crown after root canal treatment

A root-treated tooth becomes more brittle because it loses its internal tissue — especially molars, which bear heavy chewing forces. Placing a crown after root canal treatment prevents the tooth from fracturing and significantly extends its lifespan. The decision about the type and necessity of a crown is made after a careful assessment of the tooth.

Who is a candidate for root canal treatment?

• Deep decay reaching the pulp
• Abscess and root infection

• A deep crack or fracture in the tooth
• Trauma and damage to the tooth pulp
