Permanent tooth growing behind a baby tooth

Child's mouth with growing tooth behind baby tooth

We perform a baby's teething is a special event. Sometimes difficulties and abnormalities accompany this push.

If your child has a permanent tooth growing behind a baby toothIf you are a dentist, it is likely that you have questions, as this phenomenon is not trivial. In fact, it can happen that a permanent tooth erupts before the baby tooth falls out. In this case, it is important to consult a pedodontist in order to rule out any future problems or anomalies.

Why does a permanent tooth grow behind a baby tooth?

L'The timing of teething is generally the same from one baby to the next. However, it is not uncommon to see permanent teeth growing behind baby teeth. In fact, since there are delayed eruptions, some teeth may erupt early. In this case, the permanent tooth erupts before its normal eruption date and before the baby tooth has fallen out.

It is important to note that early tooth eruption has no particular clinical significance. However, tooth eruption delays should be evaluated during a dental visit to avoid any of the following situations:

  • Injury to the antagonistic gum or tongue by the natal or neonatal tooth,
  • Premature loss of the overlying temporary tooth,
  • Eruption of a supernumerary tooth visible only on X-ray,
  • Hyperthyroidism (thyroid gland disorder).

What if a real tooth grows behind a baby tooth?

When a permanent tooth grows in before the baby tooth falls out, we see two rows of teeth with the permanent tooth behind the baby tooth.

A permanent tooth growing behind a baby tooth is not a problem as long as the child does not complain of pain. However, if your child is in pain or if you have any doubts about the implantation or the proper growth of the teeth, a visit to the dentist is strongly recommended.

In the vast majority of cases, if the child is pain free, the dentist will wait until the baby tooth falls out. However, after a period of two months following the dental check-up or diagnosis, it is advisable to extract the baby tooth. The purpose of the tooth extraction is to prevent the permanent tooth from growing out of line with the dental arch. If nothing is done, the baby's permanent tooth could grow into the roof of the mouth, for example.

Please note that in case of inaction, consequences can be visible in the long term (shifted, misaligned or even crooked teeth) and cannot be corrected without a long orthodontic treatment.

Also note that other difficulties in the eruption of baby teeth may occur. It is indeed possible that the your baby's first tooth is growing crooked.

What your dentist suggests if your baby has a tooth growing in the roof of his mouth

To summarize, in the event that a permanent tooth grows in the palate of your childThe action plan would be as follows:

  • Wait for the baby tooth to fall out by itself: The final tooth will then be placed in the place of the first one,
  • If the baby tooth does not fall out or is slow to do so: the baby tooth is extracted, which will allow the permanent tooth to gradually relocate in its dedicated place.

If the second option is chosen, the dentist will anesthetize the gums with a cotton ball (or a shot if the child is old enough).

In conclusion, if you have the slightest doubt and are concerned about the eruption of an early baby tooth, don't hesitate to make an appointment with your dentist. He or she will examine your child's mouth and tell you what to do.
