After the root canal final stage (Stage III), your tooth may feel tender for a few days, especially when you chew, and your lips and tongue may stay numb for several hours. This is normal. The most important next step is the final restoration: a crown or bridge is recommended after root canal treatment to protect the tooth. This guide covers the days after root canal final stage (Stage III) treatment, care after root canal completion and why the crown after RCT should not be delayed.

What happens at the final root canal stage (Stage III)

Stage III is the final stage of root canal treatment. Before starting it, your dentist checks that the earlier stages were successful; see our guides to RCT Stage I and what to expect after the second root canal visit.

At this visit, the cleaned and shaped root canals are filled and sealed with a special filling material called gutta-percha. Sealing the canals helps prevent bacteria from entering the tooth again. The top of the tooth is then closed with a filling until the crown or bridge is made.

Numbness after the appointment

The local anaesthetic used to numb the tooth also numbs your lips, tongue and nearby teeth for several hours. While they are numb, it is easy to bite your lip, cheek or tongue. Avoid chewing anything on the side of the treated tooth until the numbness has completely worn off.

    Some discomfort after the Stage III appointment is normal, especially while chewing. You may notice mild tenderness or a dull ache in the tooth. This tenderness is expected and is not an emergency. The tooth and the area around it may feel sensitive for a few days (ADA MouthHealthy), and it should gradually ease rather than get worse.

    Care after root canal completion

    Medicines

    • Take any medicines exactly as your dentist recommends. If antibiotics have been prescribed, take them for the full number of days indicated, even if you have no discomfort or signs of infection.
    • If no painkiller was prescribed and you have sharp pain after the appointment, you can take an over-the-counter painkiller that is suitable for you, following the directions on the pack.
    • If the discomfort is not controlled with painkillers, or swelling develops suddenly, please call us straight away.

    Warm salt water rinses

    To reduce pain, swelling or discomfort, rinse with warm salt water at least 3 to 5 times a day. Dissolve a teaspoon of common salt in a cup of lukewarm water, then rinse, swish and spit. Read more about salt water rinses. Continue to brush and floss normally.

    Eating and protecting the tooth

    Until the final crown or bridge is fitted, the tooth is more likely to break:

    • Avoid biting hard foods and chewing sticky foods such as chewing gum, caramels and ice.
    • Avoid biting your fingernails, pencils or pens.
    • If possible, chew on the other side of your mouth.

    Crown after RCT: why the final restoration matters

A final crown or bridge is recommended after root canal treatment, and this may need additional appointments. A crown restores the damaged tooth and protects it from breaking. Any delay in the final restoration (crown or bridge) can result in a fracture and possible loss of the tooth. Leaving the treatment incomplete can also lead to re-infection, or re-contamination through leakage. Your dentist will advise which restoration suits your tooth and when it can be done.

Read more in do you need a crown after root canal treatment?, see our dental crowns and bridges page, and once your crown is fitted, follow our instructions after crown and bridge cementation and tips to care for crowns and bridges. Some people notice mild sensitivity after a crown for a short time.

Check-ups after root canal treatment

A root canal treated tooth can still decay, so keep up good daily care: brush twice a day, clean between your teeth and keep your regular check-ups. A periodic examination after 6 to 12 months is essential so that your dentist can confirm that the tooth has healed properly.

Most root canal treated teeth heal well, but a small number need re-treatment to achieve a good result. Read more about how long a root canal lasts and root canal re-treatment.

When to contact ADC

Please call us promptly if:

  • the pain is not controlled with painkillers, or it gets worse instead of better
  • swelling develops suddenly
  • the filling on top of the tooth breaks or comes out before your crown is fitted
  • the tooth cracks or a piece breaks off
  • your bite feels high or uneven when you close your teeth together

Get urgent medical help if you have swelling that affects your breathing or swallowing.

This article sets out the pros and cons of laser root canal therapy: what a laser adds, what the evidence shows, and what a laser does not change.

What a laser adds to root canal treatment

Laser root canal treatment usually means a standard root canal with one extra step: a thin laser fibre or tip is used inside the cleaned canals to help disinfect them. The laser does not replace the files and rinsing solutions that do most of the work. It is an add-on that some dentists use for selected teeth.

Root canal treatment removes infected or inflamed pulp, cleans and shapes the canals, disinfects them and then seals them so bacteria are less likely to return. In laser-assisted treatment, laser energy is added during the disinfection stage, in one of two ways:

  • Laser-activated irrigation: the laser tip sits in the rinsing solution and helps the solution move through the canal, including into narrow spaces.
  • Direct canal irradiation: a thin fibre is passed down the canal and moved slowly as it is withdrawn, to act on bacteria on the canal walls.

Different lasers may be used, such as diode, Nd:YAG and Er:YAG lasers. The choice depends on the equipment and the dentist's training.

If you are still unsure whether you need a root canal, start with do I need a root canal? How dentists decide. For the treatment in plain steps, read what happens during a root canal, step by step.

Why disinfection matters

The main canals have small side branches and many tiny tubes in the dentine. Bacteria can live in these spaces, where files cannot reach. Most of the cleaning is done by rinsing solutions such as sodium hypochlorite. A laser step, when it is used, is intended to help that disinfection, not to stand in for it.

What the evidence shows, and what a laser does not change

Research on lasers in root canal treatment is still developing. Laboratory studies on extracted teeth suggest that laser-activated rinsing can improve the removal of debris in some canal spaces. Clinical studies report mixed results, and a laser step is not required for every tooth.

A laser does not change the following:

  • The tooth still needs local anaesthetic. The laser does not make injections unnecessary. Modern local anaesthesia keeps most root canal visits comfortable.
  • Some soreness afterwards is still usual. Tenderness when biting for a few days is common after any root canal.
  • A crown may still be needed afterwards to protect the tooth. See do you need a crown after root canal treatment?

The laser root canal process, step by step

  1. Examination and X-rays. The dentist checks the tooth and takes X-rays, and sometimes a CBCT (3D) scan, to see the roots and any infection.
  2. Local anaesthetic and isolation. The tooth is numbed and is usually isolated with a rubber sheet (dental dam) to keep it clean and dry.
  3. Access, cleaning and shaping. An opening is made in the tooth. Files and rinsing solutions clean and shape the canals.
  4. Laser disinfection, when it is used. A thin fibre or tip is used in the canals as an extra disinfection step, either to activate the rinse or to irradiate the canal walls.
  5. Filling and a temporary or final restoration. The canals are sealed. A temporary filling may be placed, or a core and crown may be planned.

The number of visits varies with the tooth and the infection. Ask your dentist how many visits to expect in your case.

Who may benefit from a laser step

A dentist may suggest a laser step for teeth with complex canals, for long-standing infection, or for a tooth being treated again after an earlier root canal. Read more about root canal retreatment. For other teeth, thorough cleaning and rinsing without a laser is often enough. The decision is individual.

Questions to ask before treatment

  1. Does this tooth need a root canal, or are there other options?
  2. How many visits will it take?
  3. Will a laser or another activation method be used for this tooth, and why?
  4. Will I need a crown afterwards?
  5. What should I expect in the first few days?

Root canal treatment at ADC, Chandigarh

At ADC – Centre for Restorative and Implant Dentistry, root canal treatment, including laser-assisted root canal treatment, is usually carried out by Dr. Rosy Dhawan, MDS (Conservative Dentistry and Endodontics). Crowns after root canal treatment are planned by Dr. Mohit Dhawan, MDS (Prosthodontics, Crown and Bridge and Implantology). The service page is root canal treatment.

Frequently asked questions

Is laser root canal treatment safe?

When it is used by a trained dentist, with the right settings and with the tooth isolated, a laser step is an accepted add-on to standard root canal treatment. As with any dental procedure, it must be used with care so that heat does not harm the tooth or nearby tissue. Your dentist will decide whether it is suitable for your tooth.

Does a laser replace ordinary root canal cleaning?

No. Files and rinsing solutions still do most of the cleaning. The laser, when used, is an extra disinfection step.

Will I be comfortable during the visit?

Root canal treatment is done under local anaesthetic. Most people feel pressure rather than pain during the visit. Some tenderness afterwards is still usual, with or without a laser step.

Does a laser-assisted root canal smell unusual?

Some people notice a brief warm or burnt smell if the laser is used on tissue. This is a known effect of the laser and does not, on its own, mean that something has gone wrong. Tell the dentist if it bothers you.

After the second visit of root canal treatment (Stage II), it is normal for the tooth to feel tender or mildly sore, especially when you chew, and for your lips, tongue and nearby teeth to stay numb for several hours. This discomfort is expected and is no reason for alarm. This guide covers the days after root canal second visit (Stage II): what is normal, how to manage pain between root canal appointments, how to protect the temporary filling and when to contact us.

What happens at the second root canal visit (Stage II)

Root canal treatment is usually done in stages. At the first visit, the infected or inflamed pulp is removed, the canals are disinfected and a temporary filling is placed; see our instructions after RCT Stage I. The second visit continues this work:

  • Cleaning and shaping: your dentist prepares the root canals with fine hand files and rotary instruments, shaping and contouring them so they can hold a long-lasting root filling.
  • Disinfection: the canals are disinfected repeatedly to remove infection and reduce the chance of re-infection. Laser disinfection with a diode laser can be used as an additional step when your dentist feels it will help your tooth.
  • Temporary filling: the tooth is sealed again with a temporary filling until the next visit.

One or more further appointments (Stage III) may be needed to complete the treatment, when the canals are sealed. Read what to expect after the final root canal stage, or see what happens during a root canal, step by step.

Numbness after the appointment

The local anaesthetic used to numb the tooth also numbs your lips, tongue and nearby teeth for several hours. While they are numb, it is easy to bite your lip, cheek or tongue without noticing. Avoid chewing anything on the side of the treated tooth until the numbness has completely worn off.

Pain after root canal second visit: what is normal

Some discomfort after the Stage II appointment is normal, especially while chewing. You may notice mild tenderness or a dull ache in the tooth. This tenderness is expected and is not an emergency. The tooth and the area around it may feel sensitive for a few days (ADA MouthHealthy).

If you had pain before your root canal treatment started, it may take some time for the tooth to return to normal. Allow the treatment sufficient time to work.

Pain between root canal appointments

Mild pain between root canal appointments is common, because the tissues around the tooth can stay tender while the canals are being cleaned and treated. It should gradually ease rather than get worse. Pain that is not controlled with painkillers, or swelling that appears suddenly, is not expected; please call us straight away (see "When to contact ADC" below). For more on easing tooth pain, read our guide to toothache treatment.

Managing discomfort: medicines and salt water rinses

  • Medicines: take any medicines exactly as your dentist recommends. If antibiotics have been prescribed, take them for the full number of days indicated, even if you have no discomfort or signs of infection.
  • If no painkiller was prescribed: if you have sharp pain after the appointment, you can take an over-the-counter painkiller that is suitable for you, following the directions on the pack.
  • Warm salt water rinses: to reduce pain, swelling or discomfort, rinse with warm salt water at least 3 to 5 times a day. Dissolve a teaspoon of common salt in a cup of lukewarm water, then rinse, swish and spit. Read more about salt water rinses.
  • Keep cleaning: continue to brush and floss normally.

Protecting the temporary filling

Illustration: simple ways to protect the temporary filling between root canal appointments. Not a patient photograph.

A temporary filling protects and covers the tooth between root canal stages. To look after it:

  • Avoid biting hard foods and chewing sticky foods such as chewing gum, caramels and ice.
  • Avoid biting your fingernails, pencils or pens.
  • If possible, chew on the other side of your mouth.

It is not unusual for a small part of the temporary filling to wear away or break off. If the whole filling comes out, please call us straight away so that it can be replaced without delay.

Why it is important to complete your root canal treatment

Once root canal treatment has started, it is important to complete it. If the remaining stages are not completed on time, the tooth may become re-infected, may fracture, or may be re-contaminated through leakage around the temporary filling. After the canals are sealed, most teeth also need a final restoration; read do you need a crown after root canal treatment?

Keeping the treated tooth healthy

A root canal treated tooth can still decay, so keep up good daily care: brush twice a day, clean between your teeth and keep your regular check-ups. Most root canal treated teeth heal well, but a small number need re-treatment to achieve a good result. Read more about how long a root canal lasts and root canal re-treatment.

When to contact ADC

Please call us promptly if:

  • the pain is not controlled with painkillers
  • swelling develops suddenly
  • the whole temporary filling comes out
  • your bite feels high or uneven when you close your teeth together

Get urgent medical help if you have swelling that affects your breathing or swallowing.

    Please follow these Post-Operative instructions as they have been designed to assist you to heal rapidly and comfortably with minimal side effects.

    • Our Endodontist will examine and take low radiation X-Rays of the tooth. Root Canal therapy often takes two or more appointments(Stage I, Stage II, Stage III) to complete. It is important to complete the  once it has been started.
    • Local Anesthetic used to numb the teeth during Root Canal Treatment Stage I also numbs your lips, other teeth and tongue for several hours. You run through a risk of biting your own lips or tongue while they are numb. Avoid chewing anything on the side of treated tooth until the local anesthetic (Numbness) has completely worn off.
    • If you encountered pain prior to starting the Root Canal treatment, it may take some time for the tooth to get back to normal situation. Allow the Root Canal Therapy sufficient time and chance to work.
    • The preliminary objective of Stage I is to get you out of the pain. We removed the caries or cracks that allowed the bacteria to infect the nerve of the diseased tooth. Disinfection of the Root Canals along with pulp removal is undertaken effectively to get you out of the pain immediately.
    • Antibacterial medication is placed inside the tooth chamber to relieve pain and stop infection. Temporary filling is placed to seal the cavity and prevent bacteria from entering the tooth again and causing infection.
    RCT STAGE I
    • A temporary filling is used to protect and cover the tooth between Root Canal Treatment Stages. It is not uncommon for a small part of the temporary filling to break or wear down. In case the entire filling is dislodged, please call our office immediately so that we can replace it without much delay.
    •  Occasionally in case of severe infections or drainage of pus, an open dressing can be preferred by the Endodontist
    • It is normal for a patient to experience some discomfort after RCT Stage I appointment, especially while chewing. You may experience a little discomfort or even a dull tooth ache post treatment appointment. The discomfort and tenderness is normal and no reason for an emergency alarm.
    • To control discomfort you are advised to take medication as recommended by our Endodontist. If antibiotics have been prescribed, Please take them for indicated duration of days, even if there is no discomfort or no signs of infection.
    • If you were not prescribed any pain medication by our team but are experiencing sharp pain after your treatment appointment, we advise taking over the counter pain medication. Should the discomfort be uncontrolled with pain pills or sudden swelling develops, please call our office immediately.
    •  To reduce pain, swelling or discomfort it is highly advised that you rinse with warm salt water. Add half a tea spoon of common salt to a cup of Luke warm water. Stir gently and rinse every 3 to 5 times a day for next 1 week. Then rinse, swish and spit. Continue to brush and floss normally.
    • Avoid biting hard foods and chewing sticky foods such as chewing gum, Caramels, Ice etc. Avoid biting finger nails and pencils. If possible chew from the other side.
    • Failure to complete the other Stages (Stage II and III) of treatment in a time bound manner may result in possible Re-infection or tooth fracture or re-contamination due to leakage.
    • Endodontic treated tooth can still decay. You are advised to exercise proper dental care, oral hygiene, regular brushing and flossing.

    Despite our best efforts, about 90 to 95% of the Root Canal treated tooth heal successfully. Sometimes a small number of patients require re-treatment to accomplish successful results. In case of any emergency please feel free to contact our office at 0091-708-780-0016 or 0091-172-401-1943.
