A baby tooth should ideally last until it is naturally replaced by a permanent tooth, typically around the age of 6 to 12 years old.
The lifespan of a baby tooth varies depending on its position in the mouth. Here's a general timeline:
- Lower and Upper Front Teeth (Incisors): These are usually the first to be lost, starting around age 6 or 7.
- First Molars: These baby molars are typically lost around ages 9-11.
- Second Molars: These baby molars are usually the last to go, around ages 10-12.
The general timeline indicates the last baby tooth is usually lost around the age of 12 years.
However, premature loss of baby teeth can occur due to:
- Tooth Decay: Cavities can weaken teeth, leading to early extraction.
- Injury: Trauma to the mouth can cause a tooth to be knocked out.
- Disease: Certain medical conditions can affect tooth development and retention.
If a baby tooth is lost prematurely, it's crucial to consult a dentist. Early tooth loss can cause adjacent teeth to shift, potentially leading to crowding or impaction of the permanent teeth. A dentist may recommend a space maintainer to preserve the space for the erupting permanent tooth.
