Quick answer
Root canal treatment at Orion Dental Clinic in Greater Kailash 1, Delhi removes an infected pulp from inside a tooth, cleans and fills the canals and seals the tooth. Dr Anupam Sinha and Dr Natalia DeSilva use local anaesthetic, and treatment usually takes two or more appointments. A crown afterwards helps the tooth last.
01 Overview
What is root canal treatment, and how does it work in Greater Kailash 1, Delhi?
Inside every tooth is a soft core called the pulp, which runs down the root canals to the tip of each root. If the pulp becomes infected, through tooth decay, gum disease, a chipped, broken or cracked tooth or an abscess, the tooth can hurt and the infection can spread. Root canal treatment removes the infected pulp, cleans and shapes the inside of the tooth and fills and seals it so that it does not become infected again.1
It is usually the alternative to taking the tooth out. The NHS says that if an infected tooth is not treated with root canal treatment, it may need to be extracted.1 The page on tooth extraction explains that option, and the choice between them is made after an examination and X-rays.
Root canal treatment is often thought to be very painful, but the research suggests otherwise. Patients usually have pain before treatment, and in a systematic review the share with pain fell from 81% before treatment to 40% after a day and 11% after a week.4 Root canal treatment is also more successful than many people expect, although the figures depend on how success is measured, as explained below.23
Root canal treatment treats the cause of the pain, and most of the pain comes from the infection and not from the treatment.
02 Candidacy
Who needs root canal treatment in Greater Kailash 1, Delhi?
Root canal treatment is advised when the pulp of a tooth is infected or damaged, and the dentist decides after an examination and X-rays whether the tooth can be saved.1
When root canal treatment is usually advised
When another plan may be needed
- A tooth that is too badly broken or too weakened to be restored, which may need to be taken out.1
- A tooth with gum disease so advanced that it cannot be supported.
- A patient who cannot return for the appointments needed to finish and restore the tooth.1
- A tooth that cannot be restored with a crown or filling afterwards, because teeth with a crown did better.3
A tooth that can be saved and restored is usually worth treating, and one that cannot is usually better taken out.
03 Options
Which root canal treatment options are there in Greater Kailash 1?
There are choices about how many visits the treatment takes and what happens to the tooth afterwards.
Root canal treatment over two or more visits
The NHS says treatment usually takes two or more appointments of one to two hours each, with a temporary filling between visits.1
Usually 2 or more visits 1
Root canal treatment in a single visit
In a review of 10 trials, the healing rate of single-visit and multiple-visit treatment was similar, and short-term pain after filling was less common after a single visit.5
Similar healing 5
Taking the tooth out instead
If the tooth cannot be saved, or you choose not to treat it, it is taken out. See tooth extraction.1
The alternative 1
After root canal treatment the tooth is usually restored with a filling or a crown. Teeth with a crown after treatment survived better in a review of 14 studies, so ask about it. See dental crowns.3
The number of visits matters less to healing than the quality of the cleaning and the restoration afterwards.
04 Procedure
How is root canal treatment done, step by step?
Every case is individual, so your steps may differ. This is the usual order.1
The treatment cleans the inside of the tooth, and the restoration afterwards protects it.
Examination and X-rays for root canal treatment
The dentist asks about the pain, examines the tooth and the gum, and takes X-rays to see the roots and any infection at their tips.
Numbing the tooth
A local anaesthetic is given, so you are awake but should not feel pain.1 Extra anaesthetic is often needed for an inflamed tooth, so tell the dentist if you feel anything.4
Opening the tooth
The dentist drills a hole in the tooth to reach the pulp.1
Removing the infected pulp and cleaning the canals
The infected pulp is removed, any abscess is drained, and the inside of the tooth is cleaned and shaped ready for a filling.1
Filling and sealing the tooth
The canals are filled and the tooth is sealed. A temporary filling may be used between visits.1
Restoring the tooth
A crown may be needed if the tooth was badly infected.1 Teeth with a crown after root canal treatment survived longest in a review.3
Review
You come back for a check, and the tooth is X-rayed again later to see that the infection has healed.
05 Aftercare
Recovery after root canal treatment in Greater Kailash 1
Your dentist will give you written instructions, and those come first. These are the basics from the NHS.1
The first hours
Your jaw and face may stay numb for several hours, so be careful not to bite your cheek or tongue.1
The first days
The area around the tooth may feel swollen and sore, and it should get better in a couple of weeks.1 Pain is common in the first days and drops sharply by one week.4 Take paracetamol or ibuprofen as directed if you have pain.1
Protecting the tooth
Avoid knocking or biting hard on the tooth, and keep your follow-up appointments, including the one to restore it.1
Every day
Look after your teeth and gums and keep your regular check-ups.1
When to call us
Call the clinic on 098115 01995 the same day if the pain gets worse after the first few days instead of better, if swelling grows or spreads, if you have a fever, if the temporary filling comes out or the tooth breaks, or if your bite feels high. If you have trouble breathing or swallowing, or swelling that spreads across your face or neck, call 112 or go to a hospital emergency department.
Expect soreness for a few days, and call if it gets worse instead of better.
06 Limits and risks
When is root canal treatment not the right choice?
Root canal treatment saves many teeth, but it does not work for every tooth. A good dentist is willing to say so. These are situations where another plan may be better:
- A tooth that is too broken to be restored.
- A tooth with very little supporting bone or gum.
- A tooth that cannot be restored with a crown or filling afterwards.
- A patient who cannot return to finish the treatment and restore the tooth.
- A tooth that has already been treated and failed, for which a repeat treatment has a different outlook.
In these cases the tooth may be taken out, and the gap replaced, for example with an implant.
Risks and complications
Not every tooth heals. In a review of 63 studies, pooled success after at least a year was 68% to 85% when strict criteria were used, and the reported success rates had not improved over four or five decades. The authors rated the quality of the evidence as sub-optimal.2
Treated teeth can still be lost. In 14 studies, between 86% and 93% of treated teeth were still in place after 2 to 10 years, and survival was higher for teeth with a crown, with contact on both sides, that were not bridge or denture supports and that were not molars.3
Pain and soreness. Pain was common before treatment and fell sharply by a week, but extra anaesthetic was often needed.4 After filling, short-term pain was more common with several visits than with one.5
Other risks. As with any dental procedure, a tooth can fracture, a file can break inside a canal or a canal can be missed, and infection can return. Ask your dentist what applies to your tooth.
A good plan names these risks before treatment starts, and treats the restoration as part of the treatment.
07 Your visit
What happens at your first root canal consultation?
At your first visit, a dentist at Orion Dental Clinic asks about the pain: when it started, what sets it off and whether you have had swelling or a fever. You are asked about your health, medicines, allergies and earlier dental work. If you are in pain now, say so and we will see you as soon as we can.
The dentist examines the tooth, the gum and your bite, and takes an X-ray. You then talk through whether the tooth can be saved, what treatment would involve, how many visits it would take, what the options are, including taking the tooth out, and what the risks are, and you can take your time to decide, unless the infection needs treating quickly.
The first visit is to find out what is wrong and what can be done, and often treatment can begin straight away.
