Everything you should know about Root Canal Treatment

Root Canal

Toothaches and dental infections should never be ignored or simply medicated with the hope they resolve on their own. In many cases, severe tooth pain and sensitivity indicate the need for a root canal – a routine dental procedure that is highly effective at saving damaged or compromised teeth. While the thought of having a root canal may elicit feelings of anxiety or dread, the procedure has come a long way and is far less uncomfortable and cumbersome than its reputation often suggests. Here we will discuss everything you should know about a root canal treatment!

In basic terms, a root canal involves accessing the soft inner tooth tissue, pulp, and nerves, debriding out any decayed matter or infection, disinfecting and sealing the inner tooth, and then repairing the tooth with a crown.

Everything You Should Know About Root Canal Treatments

If you experience severe or persistent tooth pain, sensitivity, or infection, consult your orthodontist in Vernon dentist immediately.

Signs You Might Need a Root Canal

Here are common signs you may need a root canal and how dentists perform this important tooth-saving therapy.

Persistent tooth pain

Tooth pain that comes and goes or wakes you at night signals advanced decay, abscess or infection of the tooth’s inner pulp requiring root canal therapy. Dull, throbbing aches typically indicate inflammation or dying tissue, while severe, sharp pain usually means a pocket of infection or abscess is present. Either way, lingering sensitivity or pain to hot or cold temperatures means pulp vitality is compromised and a root canal is often the remedy to provide long-term relief.

Sensitivity to hot and cold foods

Healthy teeth with intact nerves and pulp may experience temporary temperature sensitivity. But pronounced or prolonged sensitivity to hot or cold foods or drinks indicates dying or inflamed inner pulp. The innermost pulp contains sensitive nerves and the blood supply necessary to keep teeth alive. Once decay or trauma penetrates the protective enamel and dentin layers, irritation and infection of the central pulp follow. A root canal treatment clears out the inflamed or dying pulp and nerve tissue to stop this pain-inducing sensitivity.

Swollen or tender gums

If you notice puffy, red, or tender gums around an otherwise healthy-appearing tooth, a root canal may be needed to curtail a silent infection. Dental decay and disease advance stealthily inside a tooth long before any external symptoms arise. In some cases, the body will fight back internally against invading decay-causing bacteria. This sparks inflammatory signals and infection just below the gum line even before structural damage occurs. A root canal will nip this issue in the bud.

Steps Involved in a Root Canal Treatment

The first step is an exam appointment to fully assess your afflicted tooth’s health and function. Expect dental X-rays to visualize the inner tooth anatomy and check for infection or abnormal structures. Your dentist will also closely inspect the tooth crown and surrounding gum tissues for signs of decay, fracture, swelling, or sinus tracts indicating infected inner pulp. Based on these evaluations and your symptoms, your dentist confirms whether nonsurgical root canal therapy is indeed the appropriate treatment for your situation.

With the need for a root canal established, the dentist then discusses every facet of the procedure, technology, and materials to be used as well as expected outcomes and aftercare. Patient education ensures you feel completely comfortable before undergoing the definitive root canal.


Your comfort is the top priority during a root canal, so the tooth and surrounding gum tissues are fully numbed using local anesthesia before any further treatment. Typically, mild numbing medication is first administered followed by an injection of novocaine-like agents that block sensation to the targeted area for a few hours. As the anesthetic takes effect, you should feel no pain or discomfort during the actual root canal treatment.

Removing the Pulp

After confirmation of thorough anesthesia, the root canal begins. First, a tiny hole is drilled through the top biting surface of the tooth to access the inner soft pulp tissue. Any infected or dead pulp is then thoroughly scraped out using miniature dental files of increasing sizes to shape the inner root canal spaces. This is akin to scooping out the seeds, membranes, and soft tissues from the center of a cantaloupe after slicing it open at the top.

Water irrigation flushes out any loose debris until only a clean, hollowed tooth structure remains. Your dentist may also utilize dental microscopes, ultrasonic instruments, and canal disinfecting solutions like sodium hypochlorite for the most meticulous cleansing possible.

Cleaning and Shaping

The newly hollowed pulp chamber and root canals must next be meticulously “cleaned” via precise reshaping to receive the canal fillings. Miniature files buff away debris clinging to root canal walls then smooth and widen the spaces for optimal obturation, or filling.

A final flush then cleans and disinfects the hollowed tooth mechanism one last time, prepping it for obturation with the sealant fillings.

Filling the Canal

Once cleaned, shaped, and sterilized, the open root canal system is sealed shut from bottom to top with an impervious biocompatible material to prevent future invasion of bacteria and reinfection.

In some cases, post-reinforcement and preparation for eventual crown placement also occur before a temporary filling is placed to shield the access hole between visits. That covers Everything you should know about Root Canal Treatment!

Does a root canal hurt?

While the injection of local anesthesia can cause some mild discomfort, most patients report little to no pain during the procedure thanks to thorough numbing.

How long does a root canal take?

Most root canal treatments are completed in just one 60-90 minute appointment, though teeth with more extensive decay or more than one root canal may require additional follow-up visits.

Do you need a crown after a root canal?

While not strictly necessary, getting a crown after a root canal helps strengthen the restored tooth and prevent future cracking or fractures once inner tooth tissues are removed.
