Baby Teeth Matter: Why Paediatric Dental Care Starts Early in Markham

"They're just baby teeth they fall out anyway."

It is one of the most common things paediatric dentists hear from parents. And it is also one of the most consequential misconceptions in children's oral health.

Baby teeth are temporary. But the damage caused by neglecting them is not. The habits, infections, and developmental problems that begin in the primary teeth follow children into their permanent dentition and the consequences range from crowded adult teeth requiring orthodontics to infections serious enough to require surgery under general anaesthesia.

Dental surgery for early childhood caries is the most common day surgery procedure at most paediatric hospitals in Canada. That single statistic from the Canadian Dental Association tells the full story of what happens when baby teeth are not taken seriously. PolicyMe

This guide explains why baby teeth matter far more than most parents realise, when paediatric dental care should begin, what happens when problems are left untreated, and how Markham families can give their children the strongest possible foundation for lifelong oral health.

Do Baby Teeth Need to Be Fixed?

Yes and here is why the "they'll fall out anyway" logic fails.

Treating cavities in baby teeth is necessary because the bacteria that cause decay do not disappear on their own. If left alone, the bacteria can damage nearby permanent teeth as they come in. Colgate

Baby teeth are not simply placeholder teeth that exist to fill space until the real ones arrive. They are living, functional teeth with their own nerve supply, blood vessels, and surrounding bone all of which are shared, in part, with the developing permanent teeth beneath them. An untreated infection in a baby tooth does not stay contained. It spreads through the root into the surrounding bone, where the permanent tooth bud is developing. A permanent tooth damaged by infection before it has even erupted is a problem that no amount of subsequent dental care can fully undo.

Untreated cavities in baby teeth can cause very serious harm in the short term. In the long term, untreated baby teeth cavities can cause a negative impact on how the child's mouth develops. Forestbrook Dental

Beyond infection, there is the simple reality of pain. Children feel dental pain exactly as adults do. A child with an untreated cavity is a child who is uncomfortable during meals, distracted at school, waking at night with toothache, and developing a negative association with their mouth and teeth that shapes their relationship with dental care for decades.

The 5 Critical Roles Baby Teeth Play

Understanding what baby teeth actually do makes their importance impossible to dismiss.

1. Chewing and Nutrition

Baby teeth are functional teeth they allow children to chew a normal diet that provides the nutrition essential for brain development, growth, and immune function. A toddler or pre-schooler who has lost teeth prematurely due to decay cannot chew properly. If teeth are lost too early, improperly chewed food will upset digestion. Children with significant early tooth loss often default to softer, more processed foods with corresponding nutritional consequences. Ouellettefamilydentistry

2. Space Reservation for Permanent Teeth

Each baby tooth holds the physical space in the jaw for the permanent tooth that will follow it. This is not a passive function the baby tooth actively prevents adjacent teeth from drifting into the gap it occupies. A prematurely lost baby tooth will allow neighbouring teeth to drift, blocking the space of the developing adult tooth, leading to crooked teeth. Premature tooth loss is one of the most preventable causes of orthodontic problems and one of the most expensive downstream consequences of untreated baby tooth decay. Ouellettefamilydentistry

3. Jaw Development

Chewing on healthy, properly-formed teeth stimulates the growth and development of the jaw. Chewing on well-formed teeth helps jawbones to grow properly. If some of a child's teeth are missing, the jaws can grow off balance, causing problems down the road. Jaw imbalances that develop in early childhood can require significant orthodontic or even surgical correction in the teenage years. Ouellettefamilydentistry

4. Speech Development

Teeth are essential structures for speech. Many consonant sounds particularly "th," "f," "v," "s," and "z" require specific tongue-to-tooth contact or the teeth to be present as a reference point for tongue placement. Children who lose front teeth prematurely often develop speech patterns that compensate for the gap, some of which persist even after the permanent teeth erupt. Early dental care that preserves baby teeth protects speech development during the critical early language years.

5. Psychological and Social Confidence

Children are acutely aware of how they look and how they compare to their peers. A child who has visibly decayed, discoloured, or missing front teeth experiences self-consciousness that affects their willingness to smile, speak up in class, and interact socially. Children who experience pain or noticeable decay may feel self-conscious about smiling or talking. This is not a trivial consideration the social confidence that comes from a healthy smile in early childhood contributes meaningfully to psychological development. PubMed Central

When Should Kids Start Seeing a Dentist?

The Canadian Dental Association (CDA) recommends a child's first visit take place within 6 months of the first tooth erupting and no later than 12 months of age as a dental best practice to help prevent early childhood caries. Canada.ca

Most parents are surprised by how early this is. The instinct is to wait until there are enough teeth to make an appointment "worthwhile" or until the child is old enough to cooperate. Both instincts, while understandable, work against the child's best interests.

The first dental appointment is not primarily about treatment. It is about:

• Establishing a dental home before anxiety has any chance to form

• Assessing the child's caries risk and tailoring a prevention plan accordingly

• Educating parents about brushing technique, diet, fluoride, and bottle habits

• Identifying any early developmental concerns eruption patterns, tongue tie, jaw development when intervention is most simple

A child who begins attending dental appointments by their first birthday experiences the dental office as a normal, familiar, non-threatening place. A child who first visits the dentist at age four or five often because something is already wrong has a fundamentally different and more anxious introduction to dental care.

If your child has not yet had their first appointment, the right time to book is now not when they are older. For a complete walkthrough of what happens at a first dental visit, see our detailed guide to your child's first dentist visit in Markham.

Early Childhood Caries: Canada's Most Common Childhood Chronic Disease

Early childhood caries (ECC) is the clinical term for tooth decay in children under six years of age. It is not simply a matter of a child having a "sweet tooth" or poor brushing it is a complex infectious disease with a well-documented risk profile and serious long-term consequences.

The Canadian Dental Association recognises that early childhood caries is a complex and multifactorial chronic disease that is heavily influenced by biomedical factors diet, bacteria, and host and by social determinants of health. ECC is an infectious, transmissible, diet-dependent disease that may begin soon after dental eruption and that may progress rapidly. It has a lasting detrimental impact on both primary and permanent teeth. PolicyMe

Two words in that definition deserve particular attention: infectious and transmissible.

Cavity-causing bacteria primarily Streptococcus mutans are not present in a newborn's mouth at birth. They are acquired from caregivers, most commonly through saliva contact. Sharing spoons, blowing on hot food before feeding, testing a bottle's temperature with your own mouth, or kissing a child on the lips can all transfer these bacteria from an adult's mouth to an infant's. A parent with untreated cavities is at higher risk of transmitting cavity-causing bacteria to their child.

This has a practical implication for Markham families: maintaining your own oral health is a form of protecting your child's oral health. Attending your own routine appointments and treating your own cavities reduces the bacterial load in your saliva and the risk of transmission.

What Happens When Baby Tooth Problems Are Left Untreated

The progression from a small cavity in a baby tooth to a serious health consequence follows a predictable path and it moves faster in children than in adults because baby tooth enamel is thinner and more porous.

Stage 1 Small cavity. 

A minor cavity in a baby tooth can be treated simply and quickly with a small filling. The procedure is fast, straightforward, and minimally uncomfortable with local anaesthetic. Cost is low. Recovery is immediate.

Stage 2 Cavity reaches the pulp. 

If left untreated, decay progresses through the enamel and dentine into the pulp the nerve and blood vessel chamber of the tooth. At this stage, the child begins to experience pain, particularly with sweet foods, temperature changes, and biting pressure. Treatment now involves a pulpotomy (baby root canal) or extraction. More complex, more time-consuming, and more expensive.

Stage 3 Abscess forms. 

Bacteria from the infected pulp spread through the root tip into the surrounding bone. A dental abscess develops a pocket of pus causing swelling, severe pain, and potential spread of infection to adjacent structures. Treatment requires extraction and may require antibiotics. The permanent tooth developing beneath is now at direct risk of damage.

Stage 4 Premature tooth loss. 

The tooth is lost before its natural time. The surrounding teeth begin to drift. The space for the permanent tooth closes. Orthodontic treatment braces or aligners becomes likely or necessary at significantly greater cost.

Stage 5 Surgery. 

For children with multiple affected teeth, or for children too young or anxious to cooperate with in-office treatment, dental surgery under general anaesthesia may be the only remaining option. Dental surgery for ECC under general anaesthesia is the most common day surgery procedure at most paediatric hospitals in Canada. PolicyMe

Every stage of this progression was preventable. The investment in prevention and early treatment is a fraction of the cost financial, physical, and emotional of the later stages.

Prevention: What Actually Works

The most effective approach to paediatric dental health is a combination of professional preventive care and consistent home habits. Here is what the evidence supports.

Professional Fluoride Treatments

Fluoride varnish applied by a dental professional is one of the most evidence-based interventions in paediatric dentistry. It significantly strengthens the enamel of developing teeth, making them more resistant to acid attack from bacteria. We recommend fluoride treatments twice a year along with cleanings to keep teeth their strongest. Fluoride varnish takes less than a minute to apply, is completely painless, and is recommended from the eruption of the first tooth. Canada.ca

Dental Sealants

Tooth sealants are recommended because they seal the deep grooves in your child's teeth, preventing decay from forming in these hard-to-reach areas. Sealants last for several years but will be monitored at your regular checkups. Canada.ca

The back molars which emerge around age six have deep, narrow grooves on their chewing surfaces that are virtually impossible to clean effectively with a toothbrush. Bacteria accumulate in these grooves and produce the acid that causes cavities. A sealant is a thin, tooth-coloured resin applied directly to these surfaces that seals the grooves and removes the environment where decay starts. The procedure takes minutes, requires no drilling, and is completely painless. Research consistently shows that sealants reduce the risk of cavities in back teeth by over 80%.

Home Care Habits

• Brushing: Begin with a soft infant toothbrush and a rice-grain-sized smear of fluoride toothpaste at the first tooth eruption. Increase to a pea-sized amount at age three. Parents should brush for children until at least age six to eight.

• Flossing: Begin as soon as two teeth are touching side by side often from age two to four for back teeth.

• Diet: Limit sugary and acidic drinks to mealtimes only. Avoid putting children to bed with a bottle of milk, formula, or juice liquid pooling around teeth while a child sleeps is one of the primary drivers of early childhood caries.

• Avoid sharing saliva: Do not share utensils, toothbrushes, or blow on food before feeding young children.

  
  

Routine Check-Ups

Six-monthly check-ups from the first year of life allow the dental team to monitor developing teeth, apply fluoride and sealants at the right times, catch small cavities before they become large ones, and provide parents with updated guidance as the child grows.

Managing Kids' Dental Anxiety Around Early Treatment

Many parents delay their child's first dental visit or avoid treating a cavity that has been identified out of concern that the experience will traumatise their child. This is an understandable instinct but one that typically produces the opposite of its intended outcome.

A child treated early for a small, straightforward cavity has a brief, minimally uncomfortable experience. A child whose cavity is allowed to progress to abscess level has a far more complex and distressing experience confirming the anxiety rather than preventing it.

The key is choosing a dental practice in Markham that is genuinely experienced with children one that moves at the child's pace, explains everything in age-appropriate language, and creates a consistently positive association with the dental environment over multiple visits.

Frequently Asked Questions:

Do baby teeth need to be fixed? 

Yes. Untreated cavities in baby teeth allow decay to progress to the pulp and surrounding bone, causing pain, infection, and potential damage to the developing permanent teeth beneath. Bacteria from an infected baby tooth can damage a permanent tooth before it has even erupted. Early treatment a simple filling is faster, cheaper, and less uncomfortable than the complex treatment required once decay advances. Baby teeth also hold space for permanent teeth; premature loss causes neighbouring teeth to drift and often leads to orthodontic problems.

When should kids start seeing a dentist? 

The Canadian Dental Association recommends a child's first dental visit within six months of the first tooth erupting, or by their first birthday whichever comes first. Starting this early establishes a dental home before anxiety forms, allows for early caries risk assessment, and gives parents guidance on brushing, diet, and fluoride before problems develop.

Are dental X-rays safe for children? 

Yes paediatric dental X-rays use very low radiation doses, and modern digital X-ray technology has reduced exposure further still. The diagnostic benefit of X-rays identifying cavities between teeth and beneath the gumline that are invisible to visual inspection significantly outweighs the minimal radiation exposure. The frequency of X-rays is tailored to each child's individual risk level.

What is early childhood caries (ECC)? 

Early childhood caries is the clinical term for tooth decay in children under six years of age. It is an infectious, transmissible disease caused by bacteria transferred primarily through saliva contact often from caregivers. It is one of the most common chronic diseases in Canadian children and, if untreated, is the leading reason for day surgery under general anaesthesia in paediatric hospitals in Canada.

My child is scared of the dentist should I wait until they are older? 

No waiting tends to make anxiety worse, not better, particularly if problems develop in the meantime that require more complex treatment. The most effective approach is to start early with a child-friendly practice, book brief positive visits before any treatment is needed, and build familiarity gradually. See our complete guide to managing children's dental anxiety for practical strategies.

Does my child need fluoride supplements? 

Most Canadian children get adequate fluoride through fluoridated tap water and fluoride toothpaste. Professional fluoride varnish applications twice yearly at dental visits provide additional protection, particularly for children at elevated cavity risk. Your dentist will assess your child's specific fluoride exposure and recommend supplements only if genuinely needed.
