Do Baby Teeth Need Root Canals? Common Myths Debunked

Yes, baby teeth sometimes need root canal treatment, and it's often the best way to protect your child's health. When decay or injury reaches the nerve of a baby tooth, it can cause severe inflammation or infection. In these situations, a children’s dentist may recommend a treatment such as a pulpotomy or pulpectomy to remove the damaged or infected tissue and save the tooth. This helps the baby tooth stay in place until the permanent tooth comes in.

It's a common question of many parents: "Why treat a tooth that's going to fall out anyway?" The answer is that many baby teeth, especially back molars, stay in the mouth until age 10 to 12. They hold space for the adult teeth and help your child chew, smile, and speak. An untreated infection can also spread and damage the developing permanent tooth underneath.

Below, we clear up the most common myths about baby root canals. We cover whether they hurt, when extraction is a better option, and what to expect at the appointment.

What Does a Baby Root Canal Actually Do?

A root canal treatment can help remove the infected or damaged pulp by cleaning and disinfecting the inside of the tooth to relieve pain and save the tooth rather than removing it. Plus, saving a baby tooth can also be important because RCT maintains space for the child's permanent teeth and supports normal chewing and development. 

A baby root canal is a treatment that saves a decayed or injured baby (primary) tooth instead of removing it. Inside every tooth is soft tissue called the pulp, which holds nerves and blood vessels. When deep decay or trauma reaches it, the pulp becomes infected or inflamed.

In children, this treatment usually comes in two forms– pulpotomy and pulpectomy.

Aspect	Pulpotomy	Pulpectomy
Definition	Removes affected pulp from the crown.	Removes pulp from the crown and roots.
Pulp removed	Part of the pulp.	Entire pulp.
Healthy pulp	Root pulp is preserved.	No pulp is preserved.
Used when	Damage is limited.	Pulp is severely damaged or infected.
Treatment area	Pulp chamber only.	Pulp chamber and root canals.
Main purpose	Preserve healthy pulp and the tooth.	Remove infection and save the tooth.

Note: Which one your child needs depends on how far the infection has spread. Your child's dentist will confirm this with CBCT.

Common Myths About Baby Root Canals

Myth 1: "Baby teeth fall out anyway, so treatment isn't worth it"

This is the most common child root canal treatment myth. Yes, children's teeth are temporary, but they are not unimportant.   

The Parent Should Know

Children have 20 baby teeth. Each one of them works for eating, speaking and maintaining the space needed for adult teeth until the permanent teeth come in. That's why losing a baby tooth too early because of severe decay or infection can cause problems later.

The back baby molars are especially important because they usually stay in the mouth until around age 10 to 12. If one becomes badly infected, a root canal may be needed to save the tooth until it is naturally ready to fall out. Leaving an infected baby tooth untreated can lead to pain, swelling, or an abscess.

Myth 2: Root Canal Treatment Makes a Baby Tooth Useless

Another common myth about the baby root canal is that after treatment, the tooth becomes useless. Your child may be unable to eat normally or speak. 

What Happens in Real Treatment

A pediatric dentist will first examine your child's tooth, symptoms, and overall condition with an X-ray. For more details, CBCT 3D imaging is considered to determine the extent of decay or infection. Your child receives local anaesthetic to numb the tooth and surrounding area before treatment to make your child comfortable during the process.

However, if your child is anxious about a dental visit, talking with a dental professional can help you understand their concerns, and the dentist can discuss ways to make the visit easier.

Some children may be offered nitrous oxide (laughing gas) for extra comfort. Ask your dentist which options they provide.

Questions to ask your dentist

Do not judge “root canal treatment” by someone's scary story or bad experience. 

Before treatment, you can ask questions in your mind to make the appointment less intimidating.

• How will my child's tooth be numbed?

• How will you help my child stay comfortable?

• What can I expect after treatment?

• Will my child need a crown or another restoration?

• What should I do if my child has discomfort afterwards?

Note: Some children may have mild soreness or discomfort after treatment. If your child has significant or worsening pain after treatment, contact the dentist for advice.

Myth 3: Baby Tooth Extraction Is Always Better Than RCT

Usually families assume that baby teeth will fall out anyway, so removing a badly damaged tooth seems easier than doing root canal treatment. They may also think extraction is quicker, simpler, and avoids another dental procedure.

What your dentist considers

When a baby molar is lost too early, the surrounding teeth can shift into space. Depending on the child's age and dental development, this may affect the space available for the permanent tooth and may lead the dentist to consider a space maintainer.

Extraction may still be the appropriate treatment when a tooth cannot be predictably restored or maintained.

Myth 4: A Cavity Is Not a Big Deal If My Child Does Not Have Pain

A child may have a visible cavity but still can eat, sleep and enjoy normal activities. Since there is no toothache or obvious discomfort, parents assume decay is not a big deal.

What Parents Should Know

Children often can’t describe what they feel, and baby tooth infection can be confusing because it may cause little or no pain at first. 

Parents watch for these warning signs:

• White, chalky areas on the teeth

• Brown or dark spots

• A visible hole in a tooth

• Food getting stuck repeatedly

• Sensitivity when eating

• Swelling around the gums

• Bad breath that does not go away

• Difficulty chewing

• A child avoiding certain foods

• Waking during the night because of dental discomfort

If you notice any signs, talk to your child's dentist. Most Canadian dental associations recommend a first dental visit by age one or within six months of the first tooth. Regular dental examinations help identify decay and other oral-health problems early. The dentist may recommend X-rays when they are clinically appropriate.

Myth 5: "A Baby Root Canal Will Damage the Adult Tooth"

Parents may worry that RCT treatment on a baby tooth can affect the development of an adult tooth. This concern is common because the permanent tooth is developing in the same general area.

What your dentist considers

Leaving an untreated infection can also pose risk to the developing permanent tooth. A spreading abscess can leave marks or defects on the adult tooth as it forms.

That’s why a pediatric dentist's examination needs to check the permanent tooth developing underneath, how far the infection has spread, and whether the baby tooth can be safely repaired and saved.

The materials and technique used for a primary-tooth pulpectomy are selected with the developing permanent tooth and the natural resorption of the primary tooth's roots in mind. Your dentist can explain which material is being used and why..

Myth 6: "It's too expensive, so I'll wait"

Some parents think, ‘It’s only a baby tooth, so why spend money on treatment? I’ll wait. This usually comes from the idea that baby teeth are temporary and will eventually fall out.

What Parents Should Know

Cost worries are real, and waiting is understandable. But delay tends to raise the bill. Delaying treatment can allow decay or infection to progress, potentially making treatment more complex. If cost is a concern, ask your dental office about available coverage, payment options and whether your child may qualify for programs such as Healthy Smiles Ontario or the CDCP.

Some options that may help Scarborough  families:

• For families in Scarborough, Healthy Smiles Ontario provides dental coverage for eligible children and youth aged 17 and under.

• Private dental insurance through an employer often covers a portion of pulp therapy.

• The Canadian Dental Care Plan (CDCP) may help eligible families.  Check eligibility on the Government of Canada website, since rules have changed over time

Adjusted family net income CDCP co-payment

Family Income	CDCP Co-Payment
Under $70,000	0%
70,000–79,999	40%
80,000–89,999	60%

Note: These percentages apply to eligible services at the established CDCP fee. Also, eligibility currently requires adjusted family net income below $90,000, along with other requirements such as not having access to private dental insurance and meeting Canadian tax-residency/tax-filing requirements. And additional charges can still apply because CDCP established fees may differ from a provider's actual fees.

When Might a Child Need Root Canal Treatment?

A dentist recommends Pediatric Root Canal Treatment in the following situations: 

• Deep Tooth Decay: A cavity that gets deep enough to reach near or into the pulp. Bacteria can irritate or infect the sensitive tissue, causing inflammation or infection inside the tooth.

• Dental infection: An infected baby tooth can cause swelling, tenderness, pain, bad taste or other symptoms and requires professional assessment.

• Tooth trauma: A fall, sports injury or another accident can damage the pulp inside a baby tooth, even when the tooth looks fine from the outside.

• Extensive damage: Not every baby tooth needs pulp treatment. If baby teeth are damaged but the pulp is still healthy, then the child does not need pulp treatment. However, if the pulp is inflamed or infected, then pulpotomy or pulpectomy is considered.

Signs Your Child May Need Urgent Dental Examination

Young children, especially toddlers and preschoolers, may not be able to clearly explain where their tooth hurts or what the pain feels like.

Parents may instead notice signs such as

• Complaining that a tooth hurts

• Holding or rubbing the cheek

• Avoiding chewing on one side

• Crying during meals

• Avoiding cold or hot foods

• Difficulty sleeping

• Swollen gums

• A small bump or pimple on the gum

• Facial swelling

• A visibly damaged or deeply decayed tooth

Important: Facial swelling, swelling that is spreading, difficulty breathing or swallowing, or a child who appears seriously unwell requires prompt medical assessment. Contact your dentist or seek emergency medical care depending on the severity of the symptoms.

What Happens During a Baby Root Canal Appointment?

Knowing what to expect can make the appointment easier for both you and your child.

At Dentistry at Sullivan, Dr Sepideh Maleki and her team have been serving patients since 2019. With over 13 years of experience as a general dentist, Dr Maleki and her pediatric dental team assess the tooth and symptoms to determine the right treatment. 

• Dental Examination: Team examine your child's tooth, symptoms, and oral condition.

• X-rays when clinically appropriate: Sometimes we use  X-rays to see how far the decay or infection has spread. If a closer look is needed, we recommend 3D imaging to determine the extent of decay or infection.

• Local anaesthetic:  Local anaesthetic is used to numb the tooth and surrounding area before treatment to make your child comfortable during the process.

• Pulp Treatment: Depending on the tooth condition,  a pulpotomy or pulpectomy is performed to remove damaged pulp carefully from inside the tooth.

• Cleaning & Sealing: The root canal is carefully cleaned and disinfected to remove bacteria and sealed to help prevent bacteria and further damage.

• Final Restoration: After baby RCT, the tooth needs restoration; a stainless-steel crown may be placed to protect the treated tooth and restore normal chewing function.

• Follow Up: Regular check-ups at Dentistry at Sullivan in Scarborough help monitor the treated tooth and ensure it remains healthy until the permanent tooth develops.

How Can Parents Prepare Children for RCT?

Children often pick up on how adults talk about dental visits.

• Explain it Simply: Use calm, positive words to explain to your child what will happen. Avoid words like needle or pain.

• Dentist Guidance: If you don’t explain, then let the dentist explain the procedure in child-friendly language.

• Answer their questions: Let your child share their worries and answer the questions in an age-appropriate way.

• Bring Comfort Items: Bring a favourite toy, blanket, or other familiar item if the dental office allows it. It will help your child feel relaxed during the dental visit.

• Pick a Good Time: Avoid scheduling the appointment when your child is tired or hungry because they may be anxious or less able to cooperate.

• Comfort Your Child: Let your child know you'll be there to support them. It helps your child feel safe and less anxious.

Can Baby Root Canals Be Prevented?

You cannot prevent every cavity, but daily habits can lower the risk.

The Government of Canada recommends these early oral-care steps.

Stage	What to Do
Before first tooth	Clean baby’s gums
First tooth	Start brushing
By age 1	First dental visit
Within 6 months	See a dentist after the first tooth appears

For young children, prevention includes 

• Brush Twice Daily: Encourage your child to brush twice a day with fluoride toothpaste.

• Clean Between Teeth: Help your child clean between teeth when appropriate.

• Limit Frequent sugary Snacks or Drinks: Frequent exposure to sugars gives cavity-causing bacteria more opportunities to produce acids and damage enamel.

• Choose Water Between Meals: For children over 6 months, the Government of Canada identifies water as the best drink for thirst between meals, apart from breast milk.

• Visit Dentist Regularly: Regular dental visits let the dentist spot decay early and provide customised treatment.

Why Early Treatment Matters?

It can feel tempting to "wait and see" if your child has a small cavity and no pain.

But no pain doesn't mean no problem. Often it means the decay has already worked its way deeper into the tooth, which only makes treatment more complicated.

Untreated decay doesn't always hurt, but it can still affect your child's sleep, eating, and the healthy development of their permanent teeth. Catching signs early helps your child get the right treatment before dental problems become more serious.

Note: The Government of Canada explains that untreated cavities can become larger and may lead to pain, infection, tooth breakage, or tooth loss.

Sometimes the fix is simple. Other times, a deeper cavity calls for pulp therapy. And occasionally, the tooth isn't in good enough shape to save, and another option needs to be considered.

Important: The right treatment depends on your child's actual dental condition, not on assumptions about baby teeth in general.

Aftercare Instruction for Parents

• Avoid haAvoid hard or sticky foods while your child’s mouth is numb. Since they may not feel their cheek, lip, or tongue properly, remind them not to chew on these areas until the numbness wears off.

• Some children may have temporary tenderness after treatment. Follow the dentist's instructions for pain relief and contact the dental office if your child's pain is severe, worsening or accompanied by swelling, fever or other concerning symptoms.

• Brush gently twice a day and floss around the crowned tooth.

• Keep follow-up appointments so the tooth can be monitored .
