Baby Tooth Fell Out But Permanent Tooth Is Not Coming In: What to Do?

Normal Timeline for Permanent Teeth

Permanent teeth typically emerge 1-6 months after the baby tooth falls out. However, this timeframe can vary greatly from child to child. Girls generally tend to get their teeth slightly earlier than boys.

Lower front incisors (ages 6-7) are the first permanent teeth to emerge, followed by upper incisors (ages 7-8). Molars and canines are completed between ages 9-12.

Why Might a Permanent Tooth Be Delayed?

The most common reason is insufficient space. If the jaw bone structure hasn't developed enough or neighboring teeth have narrowed the gap, the permanent tooth may struggle to emerge. This is called an 'impacted tooth.'

Other reasons include absence of the permanent tooth bud (agenesis), supernumerary teeth blocking the path, cystic formations, and tooth bud damage from trauma.

When Should You Be Concerned?

If more than 6 months have passed since the baby tooth fell out and the permanent tooth still hasn't emerged, consult your dentist. A panoramic X-ray can evaluate the presence and position of the permanent tooth bud.

Asymmetric eruption (one side came in but the other didn't) is also a situation that should be evaluated.

Treatment Options

In most cases, patient waiting is sufficient. If an impacted tooth is detected, surgical exposure and orthodontic guidance may be needed.

If the permanent tooth bud never formed (agenesis), preserving the baby tooth as long as possible is prioritized, with prosthetic solutions considered at a later age.
