When Do Kids Start Losing Teeth? Complete Guide for Parents
Concise Summary:
Most children begin losing their primary (baby) teeth around age 6, although this can range from 5 to 7 years old. The first teeth to fall out are usually the lower central incisors, followed by upper central incisors. This process continues until about age 12, when most children have lost all 20 primary teeth. Factors like genetics, nutrition, and oral health influence the timing.
Understanding Baby Teeth and Permanent Teeth
Children are born with 20 primary teeth—also known as deciduous teeth or milk teeth. These teeth play a critical role in:
- Allowing children to chew and speak properly
- Maintaining space for permanent teeth
- Supporting jaw and facial development
Permanent teeth, also called adult teeth, gradually replace baby teeth, typically starting around 6 years old. Most children have a full set of 32 permanent teeth by late adolescence.

- Primary teeth / Baby teeth / Deciduous teeth
- Permanent teeth / Adult teeth
- Incisors, Canines, Molars, Premolars
Typical Timeline: When Kids Start Losing Teeth
While every child develops at their own pace, pediatric dentists provide an approximate timeline for tooth loss:
| Tooth Type | Average Age of First Loss | Notes |
|---|---|---|
| Lower central incisors | 6–7 years | Usually the first teeth to fall out |
| Upper central incisors | 6–8 years | Often follow lower incisors |
| Upper and lower lateral incisors | 7–8 years | Side teeth around front teeth |
| First molars | 9–11 years | Larger teeth in the back |
| Canines (cuspids) | 9–12 years | Pointed teeth next to lateral incisors |
| Second molars | 10–12 years | Last primary teeth to fall out |
Note: Some children may lose teeth earlier or later. Variations of 6–12 months are common and usually not a cause for concern.
Signs Your Child is About to Lose a Tooth
Parents may notice several signs that a tooth is ready to come out:
- Loosening teeth: Teeth feel wiggly when touched
- Slight discomfort or gum soreness
- Visible gaps as permanent teeth push through
Tip: Encourage gentle wiggling, but avoid forcing a tooth out. Natural tooth loss reduces the risk of infection or gum damage.
Factors Influencing Tooth Loss
Several factors can affect when a child starts losing teeth:
- Genetics: Children often follow the dental development patterns of their parents.
- Nutrition: Adequate intake of calcium, vitamin D, and phosphorus supports healthy teeth.
- Oral hygiene: Cavities, infections, or poor oral care can delay tooth loss.
- Medical conditions: Rare conditions like hypodontia (missing teeth) or hormonal imbalances can influence timing.
Entities:
- Calcium, Vitamin D, Phosphorus
- Hypodontia
Caring for Wiggly Teeth
Even before permanent teeth emerge, proper care is essential:
- Continue brushing twice a day with a child-friendly toothpaste
- Floss gently between wiggly teeth
- Encourage a balanced diet to strengthen emerging permanent teeth
- Schedule regular pediatric dental visits
Tip: Avoid sticky candies that can worsen decay in wiggly teeth.
When to See a Dentist
Consult a pediatric dentist if:
- No teeth have fallen out by age 7 or 8
- Permanent teeth appear before baby teeth fall out (causing crowding)
- Wiggly teeth are painful, swollen, or show signs of infection
Early evaluation ensures healthy tooth alignment and prevents future orthodontic issues.
FAQs About Losing Baby Teeth
Q1: At what age do children usually lose their first tooth?
A1: Most children lose their first tooth between 5 and 7 years old, typically the lower central incisors.
Q2: Is it normal for some kids to lose teeth early?
A2: Yes. Early tooth loss may happen due to genetics or trauma and is usually normal if permanent teeth are developing properly.
Q3: Can losing teeth be painful for children?
A3: Slight discomfort is normal. Encourage gentle wiggling and soft foods to reduce pain.
Q4: What should I do if a child’s permanent teeth come in before baby teeth fall out?
A4: This is called shark teeth. Usually, the baby teeth will fall out naturally. If not, a dentist may need to remove them.
Q5: How many teeth does a child lose in total?
A5: Children typically lose 20 primary teeth, replaced gradually by 32 permanent teeth.
Key Takeaways
- Children usually start losing teeth around age 6, but 5–7 years is normal.
- The process continues until age 12, when most primary teeth have been replaced.
- Genetics, nutrition, and oral hygiene influence tooth loss timing.
- Regular dental care and monitoring are important for healthy permanent teeth.
