It's not uncommon for a 12-year-old to still have some baby teeth, but it can also indicate a dental development issue. According to the American Dental Association (ADA), permanent teeth erupt at different times. The upper bicuspids may not erupt until 10 to 11 years, and the canines may not come through until between 11 and 12 years of age.
Here's a breakdown of why your child might still have baby teeth at age 12:
-
Normal Development: The timing of permanent tooth eruption varies. Some children simply develop at a slightly slower pace. As mentioned by the ADA, the upper canine teeth can erupt between 11 and 12 years old, so it can still be normal to see a retained baby canine.
-
Delayed Eruption: Sometimes, permanent teeth are present but are slow to erupt due to various factors.
-
Impaction: A permanent tooth might be blocked or unable to emerge properly.
-
Missing Permanent Tooth (Agenesis): In some cases, the permanent tooth simply never developed.
-
Overcrowding: Insufficient space in the jaw can prevent permanent teeth from erupting correctly, causing baby teeth to be retained longer.
| Reason | Description |
|---|---|
| Normal Development | Eruption of permanent teeth varies among children; upper bicuspids may not erupt until 10-11 years, and canines until 11-12 years according to the ADA. |
| Delayed Eruption | The permanent teeth are present but are slow to erupt. |
| Impaction | A permanent tooth is blocked and can't emerge properly. |
| Missing Permanent Tooth | Also known as agenesis, the permanent tooth never developed. |
| Overcrowding | Insufficient space in the jaw prevents permanent teeth from erupting correctly, causing baby teeth to be retained longer. |
What to Do:
- Consult a Dentist: It is important to consult with a dentist or orthodontist. They can examine your child's mouth, take X-rays, and determine the underlying cause of the retained baby teeth.
- Possible Treatments: Depending on the cause, treatments may include:
- Monitoring (if it's just a matter of timing)
- Extraction of the baby tooth to allow the permanent tooth to erupt
- Orthodontic treatment to create space or guide the permanent tooth into the correct position
