Root Canal Treatment in Oakville

Your teeth have ‘roots’ that bind them to your jawbone. Pulp is a blend of blood vessels and nerves that exists inside each of your teeth. The pulp chamber, which extends down into the tooth roots, houses the pulp. The pulp chamber within the root is referred to as the root canal.

Why is root canal treatment needed?

Bacteria might enter your tooth if it is broken. If the pulp within the tooth becomes infected, the infection might move to the pulp within the root canal.

The goal of root canal therapy is to save your tooth by removing the damaged pulp and treating the infection.

You may require root canal therapy for a variety of reasons, including:

• Tooth decay that is severe
• Dental treatment on the tooth on a regular basis
• A broken tooth
• A shattered crown
• Fillings that are cracked or loose
• Periodontal disease
• A wound, such as a blow to the lips

If the infection is not treated, it might spread and cause an abscess, which is a collection of pus. This might be painful, sensitive, and cause swelling around your tooth and jaw.

Your tooth may appear darker in colour than your other teeth at times, which indicates that the nerve inside your tooth is dead or dying.

The root canal procedure is not uncomfortable. A local anaesthetic is usually used during the procedure, and it should feel no different than having a filling done.

If you are particularly concerned about undergoing root canal treatment, inform your dentist so that they can reassure you. Many of our locations also provide dental sedation to help you relax during your procedure.

Severe throbbing pain, a swollen face, or a tooth that hurts to bite on can mean infection has reached the nerve and needs attention the same day rather than at your next checkup. If that is what you are feeling right now, see our emergency dentist in Oakville page or call (289) 837-2222.

Signs You May Need a Root Canal

Not every toothache means root canal treatment, and not every tooth needing treatment aches. The signs we look for include a lingering ache that continues for more than a few seconds after something hot or cold, pain that wakes you at night or that is worse when you lie down, tenderness when you bite on one particular tooth, a tooth that has visibly darkened compared with its neighbours, a small tender bump or recurring “pimple” on the gum beside a tooth, and swelling of the gum, cheek or jaw.

Two situations deserve particular mention. First, pain that suddenly stops after being severe is not necessarily good news, because it can mean the nerve has died while the infection continues underneath. Second, facial swelling that is spreading, or any difficulty swallowing or breathing, is urgent and should not wait. See our emergency dentist in Oakville page for same-day guidance, or read what to do in a dental emergency.

What Happens During Treatment

Diagnosis

We take an X-ray and test the tooth’s response to temperature and pressure to confirm which tooth is involved and how far the infection has travelled. Referred pain is common, so testing matters more than pointing.

Anaesthetic and isolation

The tooth and surrounding area are fully numbed. A small rubber sheet isolates the tooth so it stays clean and dry, and so nothing enters your mouth during treatment. This is also what makes the procedure feel undramatic for most patients.

Cleaning the canals

A small opening is made in the biting surface, the infected pulp is removed, and the canals are cleaned, shaped and disinfected along their full length. Molars have more canals than front teeth, which is why treatment time varies between teeth.

Filling and sealing

The canals are filled with an inert material and sealed so bacteria cannot re-enter. Depending on the tooth and the amount of infection, this happens at the same visit or at a second appointment, with a temporary dressing in between.

Restoring the tooth

A root treated tooth has lost its internal blood supply and becomes more brittle, so it needs proper protection. Front teeth can often be restored with a filling, but back teeth that take heavy chewing loads usually need a crown. Skipping this step is the most common reason a successful root canal ends in a fractured tooth a year or two later.

Recovery and Aftercare

Most patients return to normal activities the same day. The tooth is often tender to bite on for a few days as the surrounding ligament settles, and over-the-counter anti-inflammatory pain relief is usually sufficient. Until the permanent restoration is placed, chew on the other side and avoid hard or sticky foods on the treated tooth, because a temporary filling is not built to take full load.

Contact us if pain increases rather than decreases after two or three days, if swelling develops, or if a temporary filling comes out. None of these are common, but all are straightforward to deal with early. Once the tooth is permanently restored, look after it exactly as you would any other tooth: brushing, cleaning between the teeth, and regular hygiene visits so the gum around it stays healthy. A root treated tooth cannot get toothache again, but it can still develop decay at the margins, and that is what we check at recall appointments.

Root Canal or Extraction?

Patients often ask whether it would be simpler to have the tooth out. Sometimes it genuinely is, and we will say so if the tooth is fractured below the gum or too little structure remains to restore. But keeping your own tooth is almost always the better outcome where it is feasible. A natural tooth root preserves the surrounding bone, keeps the neighbouring teeth from drifting, and maintains your bite in a way no replacement fully matches.

Extraction is also not the end of the cost. A gap in the chewing zone usually needs replacing with a bridge, an implant or a denture, and those options generally cost more over time than saving the tooth would have. We will lay out both paths with written costs and let you decide, and if extraction is the right answer for a wisdom tooth specifically, our wisdom teeth removal page covers that.

Cost and Coverage

Root canal treatment fees depend on which tooth is involved, because a front tooth has one canal while a molar may have three or four. We provide a written estimate before starting, including the cost of the final crown or filling so you can see the whole figure rather than half of it. Because root canal treatment restores function and treats infection, it is typically covered at least in part by Ontario dental plans, and we can submit a predetermination to your insurer first. Patients on the federal programme should see our Canadian Dental Care Plan page. If cost is the barrier, tell us, because staging the treatment is usually possible and delaying an infected tooth rarely ends up cheaper.

Root Canal Treatment in Oakville – Common Questions

Does a root canal hurt?

The treatment itself should not. The tooth is fully anaesthetised and most patients say it felt like having a long filling. The pain people associate with root canals is usually the infection beforehand, which the treatment relieves.

How long does it take?

Typically between sixty and ninety minutes per visit, and either one or two visits depending on the tooth and the level of infection. Molars take longer than front teeth.

How successful is it?

Root canal treatment has a high long-term success rate, and a properly restored tooth can last for decades. Success depends heavily on the tooth being crowned or filled promptly afterwards and on good ongoing hygiene.

Will the tooth change colour?

It can darken over time, particularly a front tooth. Internal whitening of that single tooth often works well, and where it does not, a veneer or crown restores the appearance.

Can I drive home afterwards?

Yes, with local anaesthetic only. Your lip and tongue will be numb for a few hours, so avoid hot drinks and be careful not to bite your cheek. If sedation is used, arrange for someone to accompany you.

Can antibiotics fix it instead?

No. Antibiotics can settle a spreading infection temporarily, but they cannot reach the dead tissue inside the canal, so the problem returns. The source has to be removed.

What if I put it off?

Infection inside a tooth does not resolve on its own. It typically progresses to an abscess, then to bone loss around the root, and eventually the tooth becomes unsaveable. Treating early is both simpler and less expensive.
