Baby teeth are not “temporary” teeth to be neglected. They guide jaw growth, enable a balanced diet, and hold space for permanent teeth. A child suffering from an untreated cavity is also a child who sleeps poorly, eats poorly, and concentrates less at school. At Clinique Métro Papineau, children’s oral health is a priority.
Essential Summary
| Age | Dental Stage | Recommended Action |
|---|---|---|
| 0–1 year | First baby teeth | First dental visit |
| 2–4 years | All baby teeth present | Brushing 2x/day, appropriate fluoride |
| 6–7 years | First permanent molars | Dental sealants recommended |
| 10–12 years | Baby tooth replacement | Orthodontic assessment if needed |
Key Stages of Dental Development from 0 to 12 Years
A child’s dental development follows a precise timeline every parent should know.
6 to 12 months: First baby incisors appear. Start brushing with the first tooth using a toddler-appropriate toothbrush and a rice-grain amount of fluoride toothpaste.
2 to 3 years: All 20 baby teeth are generally in place. Introduce dental floss to clean between teeth.
6 to 7 years: First permanent molars appear — the “six-year molars.” These teeth are particularly vulnerable to cavities because their deep grooves trap plaque.
10 to 12 years: Progressive replacement of baby teeth by permanent ones. This is the ideal time for a first orthodontic assessment if needed.
According to Clinique Métro Papineau, a Montreal dental clinic, children who begin regular dental visits before age 2 develop 40% fewer cavities before age 5 compared to those whose first visit occurs after age 3.
Childhood Cavities: Prevention and Treatment in Montreal
Early childhood caries (ECC) is the most widespread chronic disease in children — more common than asthma. It is caused by bacteria (Streptococcus mutans) that ferment sugars and produce acids that attack enamel.
Risk factors:
- Bottle of milk or juice at bedtime
- Prolonged night nursing without subsequent brushing
- Frequent consumption of juice, sugary drinks, or sweet snacking
- Family history of cavities
Prevention:
- Fluoride varnish application in clinic (2 to 4 times per year for high-risk children)
- Sealants on permanent molars
- Balanced diet limiting free sugars
An untreated cavity on a baby tooth can infect the permanent tooth germ beneath it. It’s never trivial to “let go” of a baby cavity.
First Dental Visit: How to Make It a Positive Experience
The first dental visit sets the tone for a lifetime. A child who has a bad experience at age 3 may avoid the dentist well into adulthood.
Here’s how to maximize the chances of a positive first visit:
- Choose a clinic with a child-friendly waiting room and staff trained in pediatric dentistry.
- Avoid negative words: “it won’t hurt,” “he won’t give you a needle” — the child’s brain retains the word “needle.”
- Play “dentist” at home before the appointment to familiarize the child.
- Schedule the visit in the morning, when the child is rested.
At Clinique Métro Papineau, first visits are often “familiarization visits”: the child tours the room, touches instruments, meets the team — with no care performed if the child isn’t ready.
FAQ: Frequently Asked Questions
At what age should my child start brushing independently?
The motor coordination needed for effective brushing is generally not acquired until age 7 to 8. Before that age, always supervise and finish your child’s brushing.
Should cavities in baby teeth be treated?
Yes, absolutely. Baby cavities can cause pain, infect the underlying permanent tooth, and require premature extraction that shifts other teeth and creates orthodontic problems.
Does RAMQ cover dental care for children in Quebec?
Yes, RAMQ covers certain dental care for children under 10. Restrictions apply depending on the type of care. Check your eligibility with Clinique Métro Papineau.
