Tooth-eating bacteria cause decay. If it is left untreated, the bacteria progress into the dental pulp and nerves of the tooth. This causes intense pain and discomfort. Progress of the infection can lead to discoloration of the tooth, swelling of the gum, discharge of pus, ultimately killing the tooth and damaging the surrounding tissues as well.
The root canal treatment removes the source of the infection by adequately disinfecting the tooth from inside.
This is a painless procedure done under a local anesthetic. At lifetime dental clinic, we provide expert professional root canal treatment, usually completed within a single or two appointments, using the latest technology, depending upon the intensity of the infection. The ultimate goal of the treatment is to preserve what is left behind than to replace the missing tooth and at the same time provide optimum health to the surrounding tooth structures.
Frequently Asked Questions
No. Root canal treatment at Lifetime Dental is performed under local anaesthesia — the procedure is not painful. Most patients report it feels no worse than a routine filling. Mild soreness for 2–3 days afterwards is normal and managed with standard pain relief. Dental anxiety patients can opt for conscious sedation for a completely relaxed experience.
Lifetime Dental’s two endodontists — Dr. Tanvi Nair (Laser RCT specialist, 11 years) and Dr.Deepika Parimoo (MDS Endodontics, 15+ years, awarded academic) — use the latest rotary
systems and laser disinfection to ensure precision, minimal trauma, and faster healing.
Common signs include: severe throbbing toothache, prolonged sensitivity to hot or cold, tooth discolouration, a pimple-like swelling on the gum, pain when biting, or a persistent bad taste. Importantly, some infected teeth cause no pain at all — only an X-ray can confirm whether infection has reached the nerve.
Root canals become necessary when oral bacteria infect the tooth’s pulp (nerve and blood vessels). Delaying treatment risks the infection spreading to bone, potential tooth loss, and increasingly complex surgical intervention. Book promptly if you have any of these symptoms.
Most root canal treatments at Lifetime Dental are completed in a single sitting — typically 60–90 minutes — using specialist rotary instruments and laser disinfection. Complex cases with severe infection or calcified canals may require two appointments. Lifetime Dental’s endodontists (not general dentists) handle all root canal cases.
The outdated belief that root canals take 3–4 sessions reflects general dental practice. When performed by a qualified endodontist using modern rotary and laser technology, single-sitting
completion is standard for most cases.
In almost all cases, yes. A root canal removes the living pulp, making the tooth brittle and significantly more prone to fracture. A crown placed over the treated tooth restores strength, shape, and normal biting function. Measurements of the crown are done digitally through an intra-oral scanner. Lifetime Dental recommends crown placement within 2–4 weeks of completing the root canal.
Crown options at Lifetime Dental include: porcelain fused to metal (PFM), full zirconia (strongest, most natural-looking) and all-ceramic crowns. Your dentist recommends the best
material based on tooth location, bite forces, and aesthetic preference.
Root canal treatment at Lifetime Dental starts at ₹5,000 per tooth, depending on tooth type (front teeth have fewer canals and are less expensive), infection complexity, the doctor performing the treatment, and the technology used. A crown is recommended after RCT (starting at ₹5,000 for children and ₹8,000 for adults). All costs are communicated before treatment begins — no surprises.
The cost reflects treatment by a qualified MDS endodontist using specialist rotary instruments, microscopic assistance where needed, and laser disinfection producing a higher standard of outcome than a general dentist performing the same procedure.
