Laser-Assisted Root Canal Treatment
Root canal treatment (RCT) is used to treat infected or inflamed dental pulp. The pulp chamber and canals are cleaned, shaped and sealed, and the tooth is then restored — often with a crown — depending on how much tooth structure remains.
Laser-Assisted Root Canal Treatment is carried out by Dr. Gajulavarthi Joel Sandeep, MDS, Implantologist & Periodontologist, at our Guntur clinic and Narasaraopet clinic.
Common reasons patients seek treatment
- Persistent toothache or sensitivity to hot and cold
- Deep decay reaching the pulp
- Swelling or tenderness around a tooth
- Trauma affecting a tooth
Who it may suit
Patients with pulp infection or inflammation where the tooth structure can still be restored, following clinical evaluation.
General benefits
- May allow the natural tooth to be retained
- Can relieve pain caused by pulp infection
- Restores the tooth for normal function after a crown or filling
Treatment process
- 01
Examination and radiographs to assess the tooth
- 02
Local anaesthesia and isolation of the tooth
- 03
Cleaning and shaping of the root canal system
- 04
Sealing of the canals
- 05
Final restoration, such as a filling or crown
Symptoms that may lead to root canal treatment
- Prolonged sensitivity to hot or cold that lingers after the stimulus is removed.
- Spontaneous or throbbing toothache, sometimes worse at night.
- Pain on biting or pressure on a particular tooth.
- A darkened tooth, or a tender swelling or gum boil near it.
- A deep cavity, crack or previously large filling — sometimes with no pain at all.
What happens during the appointment
- Examination and radiographs confirm whether the pulp is involved.
- The tooth is numbed with local anaesthesia and isolated to keep the area clean.
- The inflamed or infected pulp tissue is removed and the canals are cleaned and shaped.
- The canals are sealed, and the tooth is restored with a filling.
- A crown is often recommended afterwards for back teeth, to protect the tooth from fracture.
Aftercare
- Mild tenderness for a few days is common and usually settles.
- Avoid chewing hard food on the treated tooth until the final restoration is placed.
- Complete the recommended crown or final restoration — an unrestored treated tooth is at higher risk of fracture.
- Keep up brushing, interdental cleaning and review appointments.
Frequently asked questions
Will the tooth need a crown afterwards?
Often yes. A crown may be recommended depending on how much natural tooth structure remains after treatment.
How many visits are needed?
This depends on the tooth and the extent of infection; some cases are completed in one visit and others need more.
What is re-RCT?
Re-treatment may be advised when a previously treated tooth develops further symptoms. It is planned after clinical evaluation.
When is a root canal necessary?
When the pulp inside the tooth is irreversibly inflamed or infected — usually because of deep decay, a crack or trauma. It is confirmed by clinical tests and radiographs, not by symptoms alone.
Is it better to remove the tooth instead?
Keeping a natural tooth is usually preferred where it can be restored predictably. If the tooth is badly broken down or the support around it is poor, extraction and a replacement option such as an implant or bridge may be discussed.
How many visits does root canal treatment take?
Some cases are completed in a single visit; others need two or more, depending on the tooth, the canals and whether infection is present.
Who should consult a dentist: Consult a dentist if you have ongoing tooth pain, sensitivity that lingers, or swelling near a tooth.
Treatment recommendations vary from patient to patient. A consultation with a qualified dental professional is required to determine the appropriate treatment.
