Mouth PainOne of dentistry's most common and effective restorations, root canal therapy--or endodontic therapy--preserves infected, cracked or heavily decayed teeth. A wonderful, comfortable alternative to dental extraction, a root canal treatment take only two visits with your dentists at Ajax Dental Centre. Dr. Saeid Jafarpour, Dr. Kevin Kwong and Dr. Azza Elhaddad qualify patients with oral examination and X-rays, determining if an ailing tooth can be saved. Learn more here.

The root canal procedure

After determining a root canal treatment would help your oral health, the dentist numbs the tooth with locally-injected anesthetic. Then, a protective dam is placed and a small hole- created to access the first of two, three or even four interior chambers, or root canals.

The root canals contain soft pulp which has a blood supply, nerves and connective tissue. This pulp is prone to infection when injured through trauma, decay or even numerous restorative procedures.

During endodontic therapy, your dentist will remove the pulp from each canal using a rotary tool or a series of tiny metal files. He or she will reshape and smooth the canal walls and instill antibiotic medication. A biocompatible putty called gutta percha seals and strengthens each canal, and a temporary filling covers and protects the tooth as it heals.

When you return to Ajax Dental Centre, the doctor will remove the temporary restoration and replace it with a beautifully crafted porcelain crown. The crown blends in with the rest of your smile in terms of color, shape and size. With careful oral hygiene and professional follow-up every six months, the restored tooth can last indefinitely, says the American Association of Endodontists.

Signs you may need a root canal

Many people who need root canal treatments often experience these common symptoms:

  • Dental sensitivity to pressure, heat, color or sugar
  • A throbbing toothache
  • Gum and/or jaw swelling
  • Enamel discoloration
  • Deep crack or chip
  • Bad breath
  • Drainage
  • A pimple at the gum line
  • Red, sore gums

Unfortunately, some patients exhibit no symptoms whatsoever. So, this is why people need routine preventive care at Ajax Dental Centre. Six-month cleanings remove harmful plaque, and regular examinations detect problems as they are developing.

Root CanalSalvage your natural tooth, gums and bone: those are the aims of root canal therapy performed by Dr. Jafapour, Dr. Kwong and Dr. Elhaddad, your dentists at Ajax Dental Centre. For years, root canals have returned failing teeth to full health, appearance and function. If you're having uncomfortable dental symptoms or worry that a tooth with several fillings may break, come to Ajax Dental Centre for a root canal consultation.

Root canals and you

Actually, everyone has root canals. They are the super-narrow, pulp-filled chambers inside your tooth roots. Both baby and adult teeth have them, and through decay, accidental injury or infection, they can become inflamed. The resulting symptoms are:

  • Unrelenting toothache pain
  • Sensitivity to pressure, cold and heat
  • Darkened enamel
  • Pus, drainage and bad breath
  • Swelling of the gums and jaw
  • Red gums
  • A pimple on the gums near the affected tooth

Fortunately, you can get some relief from these symptoms with ibuprofen and ice to the jaw. However, you should see your Ajax dentist as soon as possible for an evaluation. A close examination of your tooth, including X-rays, may reveal abscess and destruction of tooth enamel and dentin (the second tooth layer) and adjoining bone. Depending on your dentist's findings, your tooth could benefit from precise root canal therapy.

Details on the treatment

While some teeth are so damaged they cannot be salvaged, many can be. Whenever possible, your professional team at Ajax Dental Centre recommends root canal therapy to extract inflamed and infected pulp and seal and support the remaining hard dental structure. Fortunately, the adult tooth can stay strong and functional without the nerves and blood vessels which run through it.

Most patients do well with simple local anesthetic during their root canal treatments. When the area is sufficiently numbed, the dentist accesses the first canal. The pulp is removed, and the dentist adds antimicrobial medication. All canals are similarly cleaned and then sealed with biocompatible gutta-percha. The dentist places a temporary restoration (crown or filling) until the final crown is ready and the tooth is fully healed.

Your restored tooth

It will be:

  • Pain-free
  • Infection-free
  • Strong
  • Natural-looking and functioning
  • Long-lasting

In fact, your restored tooth is far superior to any conventional tooth replacement option and should last far longer, too.

It’s often best health-wise to preserve even the most troubled tooth—including a child’s primary (“baby”) tooth. If that sounds like too much effort for a tooth that lasts only a few years, there’s a big reason why—if it’s lost prematurely, the incoming permanent tooth above it could erupt out of position.

Preserving a decayed primary tooth could include procedures similar to a root canal treatment, commonly used in adult permanent teeth with inner decay. However, we may need to modify this approach to protect the primary tooth’s pulp. This innermost layer plays a critical role in early dental development.

Because an adult tooth has reached maturity, removing diseased pulp tissue has little effect on its permanent health. But the pulp contributes to dentin growth (the layer between it and the outer enamel) in primary and young permanent teeth, so removing it could ultimately compromise the tooth’s long-term health.

Our goal then with a child’s tooth is to remove as much diseased tissue as possible while involving the pulp as little as possible. What techniques we use will depend on how much of the pulp has become infected.

For example, if decay has advanced to but hasn’t yet penetrated the pulp, we may remove all but a small amount of the decayed structure just next to the pulp to avoid its exposure. We may then apply an antibacterial agent to this remaining portion and seal the tooth to curb further infection.

If on the other hand the pulp has become infected, we may try to remove only the infected portion and leave the remaining pulp intact. We’ll only be able to do this, however, if we deem the remaining pulp healthy enough to remain infection-free after the procedure. If not, we may need to remove the entire pulp as with a traditional root canal. This option, though, is a last resort due to the possible effect on dentin growth and the tooth’s long-term health.

As you can see attempts to preserve a primary tooth can be quite involved. But if we can help it reach its full life span, it could mean better dental health for a lifetime.

What your dentists in Ajax, Ontario want you to know

There are many tales about root canals which can make you fearful. The truth is root canals have become the state-of-the-art dental root canaltreatment to relieve tooth pain and still keep your tooth. Not too long ago, your only choice to relieve pain from a badly decayed tooth was to remove the tooth.

Now, thanks to modern techniques, materials and tools, you can save your painful tooth. The answer is root canal therapy. Your dentists at Ajax Dental Centre in Ajax, Ontario want to share with you why root canals are nothing to be afraid of.

Many dentists agree your best choice is to keep a tooth whenever possible. If you have a tooth removed, you are faced with:

  • Living without the tooth, giving you an incomplete smile
  • Replacing the tooth with a removable partial which can move around, making it difficult to eat or speak
  • Replacing the tooth with bridgework, requiring restoration of the adjacent teeth to support the bridge
  • Replacing the tooth with a dental implant which can be expensive

Why not keep your tooth with root canal therapy? Your dentists in Ajax, Ontario can perform root canal treatment using the latest anesthesia procedures to make you comfortable. When the treatment area is completely numb, your dentist will remove the diseased tissue from inside your tooth, replacing it with a sedative material. This material calms the tooth down, relieving pain and pressure. When your tooth is no longer painful, your dentist will place an inert, rubbery material called gutta-percha into the tooth. Your dentist will close the tooth with a filling, or place a dental crown to protect the tooth and your treatment is complete.

You may need a root canal if you have deep dental decay or tooth trauma from an accident or injury. Whatever the cause of your tooth pain, when you visit Ajax Dental Centre, you can be assured of the best experience before, during, and after your root canal treatment.

If you need a root canal, don’t be afraid. Let your dentists at Ajax Dental Centre in Ajax, Ontario take away your pain. Help is just a simple phone call away, so call today!

If you think your child is too young to need root canal treatment, think again — there is no age limit for this treatment. If his/her primary (baby) teeth have been injured, or if decay has advanced deep into the roots of your child's teeth, a root canal treatment to stabilize teeth may be needed. Root canal treatment removes infection from the pulp, the living tissue that is found inside the tooth's roots. The pulp contains the tooth's nerves, so tooth pain is often an indication that decay has moved into the pulp.

When performing root canal treatment on primary teeth, we must keep in mind that the primary teeth's roots will be resorbed as part of the normal process in which the body makes room for the growing permanent teeth that will take their place.

If a child experiences tooth pain that is related to changes of temperature or pressure, or exposure to sweet or acidic foods, the infection is likely to be minor and easily repaired. But if he or she feels a constant or throbbing pain regardless of stimulation, it may indicate an extensive infection of the pulp and surrounding area.

If the infection is advanced, the baby tooth may have to be removed. But if baby teeth are lost prematurely, a malocclusion (from “mal” meaning bad and “occlusion” meaning bite) can easily result; so we make every effort to keep the baby teeth in place to guide the permanent teeth that are forming underneath them, inside the child's jaw. In such cases an endodontist (from the root “endo” meaning inside and “dont” meaning tooth) or pediatric dentist may perform root canal treatment, removing the diseased and infected pulp from within the tooth's roots and replacing it with a substance that can be absorbed when it is time for the baby tooth's roots to be resorbed naturally.

When baby teeth are injured through a fall or blow to the face (referred to as traumatic injury) they may develop discoloration varying from yellow to dark gray. This is a sign of damage to the pulp tissues inside the tooth's roots. Dark gray discoloration often indicates that the pulp tissues have died. In such cases root canal treatment is needed to remove the dead tissue. If a tooth is completely knocked out of the child's mouth, most dentists agree that it should not be replanted because of the risk of damage to the developing tooth underneath.

Root canal treatment for baby teeth is a better choice than tooth removal if at all possible. It helps a child retain full function of their teeth, jaws and tongue, preventing speech problems, and it helps guide the permanent teeth into their proper places.
