Root Canal Treatment in Woodbridge: Save Your Tooth and Stop the Pain

Root canal treatment in Woodbridge removes infected or inflamed pulp from inside a tooth, cleans and seals the canals, and lets you keep your natural tooth. A toothache that lingers after hot or cold, or swelling near a tooth, is a common sign the nerve is in trouble. It’s very treatable, but it won’t heal on its own, so book an exam at Columbus Dental Centre before a small problem becomes an abscess.

Severe pain at night or facial swelling should be treated as urgent. As an emergency dental clinic in Woodbridge, we make room for patients in pain as quickly as we can.

What is a root canal?

Quick answer

A root canal is a procedure that treats the soft tissue (pulp) inside a tooth when it becomes infected or badly inflamed. The dentist numbs the tooth, removes the damaged pulp, disinfects and shapes the canals, then fills and seals them. Most back teeth then get a crown for strength.

Many root canals start as a cavity that went too deep. Catching decay early with fillings and restorations is the easiest way to avoid one.

After treatment, a back tooth usually needs a crown. With CEREC same day crowns in Woodbridge, we can often mill and place a ceramic crown in one visit instead of leaving you with a temporary for weeks.

For some gum and soft-tissue problems around a treated tooth, laser dentistry can be a gentler option.

And if a tooth is too damaged to save, we’ll talk through painless tooth extraction and replacement openly. Ready to get it checked? Book a root canal assessment online.

What are the signs you need a root canal?

Some infected teeth hurt a lot. Others barely hurt and only show up on an X-ray. Watch for these signs.

01

Lingering sensitivity

Pain from hot or cold that lasts 30 seconds or more after the food or drink is gone.

02

Throbbing or night pain

A deep ache that wakes you up or pulses with your heartbeat often means the pulp is inflamed.

03

Pain when biting

Sharp pain when you chew or tap on the tooth can point to infection around the root tip.

04

Swelling or a gum pimple

A bump on the gum that oozes or keeps coming back is often a draining abscess.

05

A darkening tooth

A tooth that turns grey or darker after an injury may have a dying nerve.

06

A deep crack or chip

Fractures that reach the pulp let bacteria in, even before the tooth starts to hurt.

Some infected teeth cause no symptoms at all. That's one reason regular checkups with X-rays matter.

Is a root canal painful?

Short answer

With modern local anesthetic, a root canal usually feels like getting a large filling. Most of the pain people connect with root canals comes from the infection beforehand, and treatment is what relieves it. Mild tenderness for a few days afterward is normal.

Lots of people walk in nervous, so comfort is built into every step:

  • Numbing gel before the injection, and time for the freezing to work fully
  • A rubber dam to keep the tooth dry and stop debris reaching your throat
  • Breaks whenever you need them, with a hand signal agreed in advance
  • Clear updates on each step, so nothing comes as a surprise

Very inflamed teeth

A “hot” tooth with severe inflammation can be harder to numb. When that happens, we use additional anesthetic techniques, or settle the tooth down first and finish at a second visit.

If you have strong dental anxiety, tell us when you book. We’ll plan a longer appointment and discuss sedation where it’s appropriate.

What happens during root canal treatment?

Here's each stage of root canal therapy at our Woodbridge dental office.

  1. Exam and digital X-rays

    We check the tooth, test how the nerve responds and take digital X-rays to see the root shape and any infection at the tip.

  2. Freezing the area

    Local anesthetic numbs the tooth and the gum around it. We confirm it's fully numb before starting.

  3. Isolation with a rubber dam

    A thin sheet isolates the tooth, keeping it clean and dry throughout treatment.

  4. Removing the pulp

    A small opening is made in the top of the tooth, and the infected or inflamed pulp is removed from the chamber and canals.

  5. Cleaning and shaping

    Fine instruments shape each canal while disinfecting rinses wash out bacteria. Badly infected teeth may get medication and a temporary filling between visits.

  6. Filling and sealing

    The canals are filled with a rubber-like material called gutta-percha and sealed so bacteria can't get back in.

  7. Crown or final restoration

    Back teeth usually get a crown to protect them from cracking. Front teeth sometimes only need a filling.

Most root canals take 1 or 2 visits of roughly 60 to 90 minutes each. Molars have more canals, so they take longer than front teeth.

Is a root canal on a front tooth different from a molar?

Yes, mostly in time and complexity. Front teeth usually have a single, fairly straight canal. Molars at the back can have 3 or 4 canals, sometimes curved, narrow or hard to find.

Front teeth

Treatment is often finished in one visit. Because front teeth take lighter biting forces, many only need a tooth-coloured filling afterward. If the tooth has darkened, internal whitening or a veneer can bring the colour back in line with its neighbours.

Premolars

These usually have 1 or 2 canals. A crown is often recommended, especially if the tooth already had a large filling.

Molars

Molars take the heaviest chewing load and have the most complex root systems. Treatment can take longer or need a second visit, and a crown is almost always recommended afterward to protect the tooth from cracking.

Whatever the tooth, we’ll show you the X-ray, explain how many canals we expect to treat and give you a realistic idea of the number of visits before we begin.

Root canal vs extraction: which is better?

Both stop the infection. The difference is what you're left with afterward.

FactorRoot canal and crownExtraction

Chewing and biteStays normalChanges unless the gap is replaced
Nearby teethStay in placeCan drift into the gap

Treatment time1 to 2 visits plus a crownUsually 1 visit
Long-term costUsually less than extraction plus an implant or bridgeLower upfront; replacing the tooth adds more later
Best whenThe tooth has enough healthy structure to restoreThe tooth is cracked below the gum or too damaged to save

When a tooth can be restored, saving it is usually the better choice. When it can't, we'll explain replacement options such as implants, bridges or dentures.

What causes the pulp inside a tooth to get infected?

The pulp is the living core of the tooth: nerves, blood vessels and connective tissue. Enamel and dentin protect it, so bacteria need a way in.

  • Deep decay. The most common cause. A cavity left untreated eventually reaches the pulp.
  • Cracks and chips. Even hairline cracks can let bacteria through.
  • Repeated dental work. Teeth that have had several large fillings over the years are more prone to pulp problems.
  • Trauma. A blow to the mouth can damage the nerve, sometimes years before symptoms appear.
  • Leaking old fillings or crowns. Gaps at the edges let decay start underneath.

Is a toothache an emergency?

A lingering toothache is urgent but usually not dangerous today. Swelling is a different story. Facial swelling, fever or a bad taste with pain means infection may be spreading, so call us the same day. If swelling reaches your eye or neck, or you have trouble breathing or swallowing, go to a hospital emergency department right away.

How we confirm a tooth needs a root canal

We don’t guess. Diagnosis combines your symptoms, a cold test to see how the nerve responds, tapping and biting tests, a gum check and digital X-rays. Sometimes a tooth needs only a new filling, and sometimes the pain is coming from a different tooth than the one you’d point to. Getting the diagnosis right is half the treatment.

Who performs root canals: a general dentist or an endodontist?

Quick answer

Both can. In Ontario, general dentists registered with the RCDSO routinely perform root canal treatment. Endodontists are specialists with extra training who often handle complex cases, such as calcified or very curved canals, retreatments and root-end surgery.

Most front teeth and premolars, and many molars, are treated in a general practice like ours. It saves you a referral, a second set of X-rays and often weeks of waiting while the tooth hurts.

When a case looks complex on the X-ray, we’ll say so before starting. Sometimes the best plan is to refer you to an endodontist and then place the crown here afterward. You won’t be pushed into treatment that belongs with a specialist.

Questions worth asking any dentist

  • How many canals does this tooth have, and do any look difficult?
  • Will I need a crown, and when?
  • What happens if the tooth doesn’t respond as expected?
  • What would extraction and replacement involve instead?

What are the most common root canal myths?

Root canals have a bad reputation they mostly don't deserve. Here's what the evidence says.

Myth

Root canals are extremely painful.

Fact

With modern anesthetic, most patients say it feels like a filling. The infection causes the pain; treatment relieves it.

Myth

Pulling the tooth is always simpler.

Fact

Extraction often leads to drifting teeth, bone loss and the need for an implant or bridge. Your natural tooth, when it can be saved, is usually the best tooth you'll have.

Myth

If the pain stops, the infection is gone.

Fact

Pain can stop because the nerve has died. Without treatment, the infection can stay and spread into the bone.

Myth

Root canals make you sick.

Fact

This idea comes from research done about 100 years ago that has since been discredited. Current evidence doesn't link root canal treatment to illness elsewhere in the body.

Myth

A root-canal-treated tooth only lasts a few years.

Fact

With a good crown and regular care, treated teeth often last for decades, many for a lifetime.

What is recovery like after a root canal?

Most people go back to work or school the same day. Expect the tooth and gum to feel tender for 2 to 5 days, especially when you bite.

Aftercare tips

  • Wait until the freezing wears off before eating, so you don’t bite your cheek or tongue
  • Chew on the other side until your final crown or filling is placed
  • Take over-the-counter pain relief as your dentist recommends
  • Keep brushing and flossing, gently around the treated tooth
  • Get the permanent crown on schedule, because a tooth with a temporary filling can crack

Call us if

  • Pain gets worse after 3 days instead of better
  • Swelling appears or increases
  • Your bite feels high or uneven
  • The temporary filling falls out

What can you eat after a root canal?

Once the freezing wears off, soft foods are easiest for the first day or two: eggs, yogurt, soup, pasta, fish, rice and cooked vegetables. Avoid very hard, sticky or chewy foods on that side until the final crown is in place. Hot and cold drinks are fine as long as they feel comfortable.

How much does a root canal cost in Woodbridge?

Short answer

The cost of a root canal depends mostly on which tooth is treated, because molars have more canals than front teeth. Retreating an old root canal, extra visits for a severe infection and the crown afterward also affect the total. You get a written estimate before we start.

Insurance and CDCP

Most dental plans cover root canal treatment under basic or major services. The Canadian Dental Care Plan covers root canal treatment as a basic service for eligible patients, and we bill Sun Life directly. A crown afterward may need preauthorization.

Why treating it early costs less

Treating a tooth while it can still be restored is usually far less involved than removing it and replacing it later with an implant or bridge. Waiting also gives a small infection time to become a large one.

What if an old root canal starts hurting again?

Most root canals succeed for many years. Sometimes, though, a treated tooth gets reinfected, often because a crown leaked, a new crack formed, or a canal was very curved or hidden.

Your options

  • Retreatment. The old filling material is removed, the canals are cleaned again and resealed.
  • Root-end surgery. For some teeth, a small surgical procedure at the root tip clears the infection.
  • Specialist referral. Complex anatomy may be best treated by an endodontist, and we’ll coordinate that if needed.
  • Extraction and replacement. When the tooth can’t be saved predictably, we plan the replacement with you.

Signs to watch for include tenderness when biting, a gum bump near an old root canal tooth, or swelling. Don’t wait it out. An X-ray usually tells us quickly what’s going on.

How can you avoid needing a root canal?

Not every root canal is preventable, especially after trauma. But most start with decay or cracks you can do something about.

01

Treat cavities early

Small cavities are quick fillings. Large ones creep toward the nerve. Regular checkups catch them while they're small.

02

Wear a night guard if you grind

Grinding and clenching cause cracks that can reach the pulp. A custom guard takes the force instead of your teeth.

03

Protect teeth during sports

A mouthguard for hockey, basketball or martial arts can prevent the kind of knock that kills a nerve.

04

Replace leaking fillings

Old fillings and crowns with gaps at the edges let decay start underneath where you can't see it.

05

Go easy on ice and hard candy

Chewing ice, pens or hard candy is a common way to crack a tooth.

06

Keep up with daily care

Brush twice a day with fluoride toothpaste, clean between your teeth daily and cut back on sugary snacks and drinks.

Do children ever need root canal treatment?

Yes, though it usually looks different. When decay reaches the nerve of a baby tooth, the dentist may do a pulpotomy, removing only the infected top part of the pulp and placing a medicated filling, often followed by a crown.

Why fix a baby tooth that will fall out anyway? Because some baby molars stay until age 10 to 12. They hold space for adult teeth, help kids chew and speak, and an infection there can affect the adult tooth developing underneath.

For older kids and teens with adult teeth, root canal treatment works much the same as it does for adults. If your child has a toothache, swelling or a darkening tooth after a fall, book an exam soon. We’ll explain everything in kid-friendly language and keep the visit as calm as possible.

Root canal treatment in Woodbridge: frequently asked questions

How long does a root canal take?

Most root canals take 1 or 2 appointments of about 60 to 90 minutes. Front teeth are usually quicker, while molars with 3 or 4 canals take longer.

Can I drive after a root canal?

Yes, in most cases. Local anesthetic does not affect your ability to drive. If you had sedation, arrange for someone to take you home.

Do I need a crown after a root canal?

Back teeth almost always need a crown because they take heavy chewing forces and become more brittle after treatment. Front teeth sometimes only need a filling.

Will antibiotics fix a tooth infection without a root canal?

No. Antibiotics can calm a spreading infection for a while, but they cannot reach the infected tissue inside the tooth. The source has to be removed with a root canal or an extraction.

How long does a tooth last after a root canal?

With a well-fitted crown and good oral care, a treated tooth can last for decades and often a lifetime. Regular checkups help catch any problem early.
