In short

Root canal treatment, also called endodontic treatment, removes the inflamed or infected nerve from inside a tooth, then cleans, disinfects, fills and seals the root canals, with the aim of keeping the natural tooth. Dr. Binyahya Dental Clinic in Hajer District, Dhahran, provides root canal treatment and re-treatment, carried out by Dr. Mohammed Abdullah, who has about 15 years’ experience and more than 4,000 successful root canal cases. Suitable cases are completed in one visit, using rotary instruments with laser assistance.

Deep or persistent toothache can be a sign that the nerve inside the tooth is inflamed. Root canal treatment, also known as endodontic treatment and often called “having the nerve removed”, aims to keep the natural tooth rather than extract it. When deep decay or a crack reaches the pulp, the living tissue inside the tooth that holds the nerve and blood vessels, the pulp can become inflamed or infected, and this usually does not settle on its own. During treatment the affected pulp is removed, and the root canals are cleaned, disinfected, filled and sealed.

Diagnosis does not rest on how severe the pain is. The dentist examines the tooth and the gum around it and uses X-rays to assess the nerve, the roots and the surrounding bone; the digital panoramic X-ray is taken in the clinic during the same visit. On that basis the dentist decides whether the tooth needs root canal treatment. Not every tooth can be kept: when a root has cracked lengthwise, too little of the tooth remains to restore, or most of the supporting bone has been lost, extracting and replacing the tooth may be the better option, and the dentist explains this to the patient before a decision is made.

Suitable cases are completed in a single visit, from opening the tooth to sealing its canals. An active abscess or swelling, curved canals, or a tooth that has been treated before may need two visits or more, with medication and a temporary filling placed in the tooth in between; Dr. Mohammed Abdullah sets the number of visits after the examination and X-ray. He has about 15 years in preventive and restorative dentistry and more than 4,000 successful root canal cases, and his work covers acute tooth pain, advanced root canal treatment and re-treatment of root canals that were not successful the first time.

Treatment does not end when the canals are sealed. A tooth loses some of its strength after root canal treatment and usually needs a final filling or a crown to protect it from fracture, particularly a back tooth, which bears the load of chewing. Delaying this step can leave the tooth open to fracture or to bacteria re-entering the canals, so it is advisable not to leave a long gap between the root canal and the final restoration. The final filling and the crown are both provided at the clinic.

Treatment at the clinic

Advanced root canal treatment and acute tooth pain

Root canal treatment is carried out by Dr. Mohammed Abdullah, who has about 15 years in preventive and restorative dentistry and more than 4,000 documented successful root canal cases. His work covers acute tooth pain and advanced root canal treatment.

A single visit for suitable cases

Suitable cases are completed in one appointment, from opening the tooth to sealing the canals. After the examination and X-ray, the dentist decides whether a case is suitable or needs a second visit.

Rotary cleaning and shaping of the canals

The rotary system cleans and shapes the root canals electronically with motor-driven instruments, which helps prepare them evenly and often in less time.

Laser-assisted canal disinfection

The laser is a supporting technique that helps disinfect the root canals; it does not replace cleaning and rinsing them with disinfecting solutions. The dentist decides whether a case calls for it.

Root canal re-treatment

Inflammation can return to a tooth that has had a root canal if bacteria remained in a canal that was not cleaned, or leaked into it later. Dr. Mohammed Abdullah then re-cleans, disinfects and reseals the canals where the case allows, with the aim of keeping the tooth rather than extracting it.

In-clinic panoramic X-ray and a dedicated sterilization room

The digital panoramic X-ray unit is in the clinic, so the tooth is imaged during the same visit, and instruments are sterilized in a dedicated sterilization room before use.

When is this treatment advised?

  • Severe or throbbing toothache, particularly pain that wakes the patient at night or worsens on lying down.
  • Sensitivity to hot or cold that lingers for minutes or longer after the trigger is gone.
  • Pain when chewing or when pressure is applied to the tooth.
  • Swelling of the gum or face, or an abscess or pimple-like bump near the tooth.
  • A tooth turning darker, particularly after a knock or an old injury.
  • Deep decay or a crack that has reached the nerve, as seen on examination and X-ray.
  • Pain or infection returning in a tooth that has already had a root canal, which may call for re-treatment.
  • There may be no symptoms at all, and the dentist finds an inflamed or damaged nerve at a routine check-up and X-ray. In every case, the dentist decides after the examination whether the tooth needs root canal treatment.

Treatment steps

  1. 1

    Examination and X-ray

    Dr. Mohammed Abdullah examines the tooth and uses X-rays to assess the nerve and roots; the digital panoramic X-ray is taken in the clinic. He then explains the plan, the expected number of visits and the cost before treatment starts.

  2. 2

    Local anaesthesia

    The area around the tooth is numbed with a local anaesthetic, and the dentist checks that it has taken effect before starting. Nitrous-oxide (laughing-gas) sedation is available; the dentist decides on its use according to the patient’s health and level of anxiety.

  3. 3

    Opening the tooth and removing the nerve

    The dentist makes a small opening in the surface of the tooth and removes the inflamed or infected pulp from the pulp chamber and from each canal.

  4. 4

    Cleaning and disinfecting the canals

    The canals are cleaned and shaped with the rotary system and rinsed with disinfecting solutions, and a laser is used to help disinfect them where the case calls for it.

  5. 5

    Filling and sealing the canals

    The canals are filled with a dedicated root-filling material and sealed to keep bacteria out. In suitable cases this is completed in the same visit; otherwise medication and a temporary filling are placed until the next appointment.

  6. 6

    Final filling or crown

    After root canal treatment, a tooth usually needs a final filling or a crown to protect it from fracture, especially a back tooth. The dentist recommends what suits the case, and it is done at the clinic.

Aftercare instructions

  • Do not eat until the numbness has completely worn off, which can take a few hours, because the numbness can lead you to bite your cheek or tongue without noticing.
  • Mild soreness or tenderness when biting is expected for a few days, because the tissue around the root is irritated; it usually eases with the painkiller the dentist prescribes or recommends.
  • Chew on the other side and avoid hard or sticky foods on the treated tooth until the final filling or crown is in place, because the tooth is weaker than usual until it is restored.
  • A little of a temporary filling may wear away. If it falls out or breaks, contact the clinic, because it protects the canals from bacteria until the next appointment.
  • Keep brushing and flossing as usual, gently around the treated tooth, to keep the area clean without irritating it.
  • If the dentist prescribes an antibiotic or other medicine, take it exactly as directed for the full course, because stopping an antibiotic early can allow the infection to return.
  • Do not put off the final filling or crown: delaying it can leave the tooth open to fracture or to bacteria re-entering the canals.
  • Contact the clinic on 0538588580 if the pain gets worse after two or three days instead of easing, if swelling appears, or if the bite feels high on that tooth. Swelling that spreads quickly, or comes with fever or difficulty swallowing or breathing, needs hospital emergency care straight away.

Frequently asked questions

Can a root canal be done in one visit?

Yes, in suitable cases, and Dr. Mohammed Abdullah decides after the examination and X-ray whether a tooth is one of them. Some cases, such as an active abscess or swelling, complex canals or a re-treatment, may need two or more visits, with medication and a temporary filling placed in the tooth in between.

How many visits does root canal treatment take, and how long is each visit?

One visit is enough for suitable cases; complex cases and re-treatments need two or more, and Dr. Mohammed Abdullah gives the expected number after the examination and X-ray. The length of a visit depends on the tooth and how many canals it has: molars, which have several canals, take longer than front teeth.

Is a root canal painful?

Root canal treatment is done under local anaesthetic, and many patients feel mainly pressure rather than pain during it; the treatment itself removes the source of the pain, the inflamed nerve. Mild soreness or tenderness when biting may remain for a few days and usually eases with painkillers. Laughing-gas sedation is available, and the dentist decides whether it is suitable according to the patient’s health and level of anxiety.

What is root canal re-treatment, and when does a tooth need it?

Re-treatment is a new root canal treatment on a tooth that was treated before and has become painful or inflamed again, and Dr. Mohammed Abdullah carries it out. Inflammation can return if bacteria remained in a canal that was not fully cleaned, or leaked into it after a delayed crown or through new decay. The dentist removes the old filling material, then re-cleans, disinfects and reseals the canals under local anaesthetic, sometimes over more than one visit. After the examination and X-ray, the dentist decides whether the tooth can be kept.

Does a tooth need a crown after a root canal?

Often yes, especially a back tooth, because a tooth becomes weaker after root canal treatment and more likely to fracture; the dentist decides based on how much of the tooth remains. A front tooth with plenty of healthy structure left may only need a filling. Crowns and fixed bridges are provided at the clinic, and it is advisable not to leave a long gap between the root canal and fitting the crown.

When can I eat after a root canal, and will it hurt afterwards?

Eating is fine once the numbness has completely worn off, which usually takes a few hours. Until the final filling or crown is placed, chew on the other side and avoid hard or sticky foods, to protect the tooth from fracture. Mild soreness or tenderness when biting for a few days is expected and usually eases with painkillers; if the pain gets worse or swelling appears, contact the clinic on 0538588580.

Who carries out root canal treatment at the clinic?

Root canal treatment is carried out by Dr. Mohammed Abdullah, who has about 15 years in preventive and restorative dentistry and more than 4,000 successful root canal cases. His work covers acute tooth pain, advanced root canal treatment and re-treatment of root canals that were not successful the first time, using rotary instruments and, where the case calls for it, a laser.

How much does a root canal cost?

The cost is set after the examination; contact us on 0538588580. It depends on the tooth, how many canals it has, whether this is a first treatment or a re-treatment, and whether a filling or a crown is needed afterwards. The dentist explains the plan and its cost to the patient after the examination and X-ray, before treatment begins.

Does the clinic see patients with acute tooth pain?

Yes, Dr. Mohammed Abdullah treats acute tooth pain. Appointments are booked by phone or WhatsApp on 0538588580 within opening hours, Saturday to Thursday from 2:00 PM to 10:00 PM; the clinic is closed on Friday. The dentist starts with an examination and X-ray to find the source of the pain before recommending treatment.

Does insurance cover root canal treatment?

For insurance questions, contact the clinic on 0538588580 by phone or WhatsApp; it is also advisable to check the details of the policy with the insurer. An examination can be booked in the same call, since the root canal plan and its cost are set after it.
