When the child first starts exploring the world by themselves, with the help of their first baby walker, they are exposed to falls that can affect their face and teeth.

During the first years of life, the primary teeth are very closely related to the permanent teeth, which are forming inside the bone.

When injury occurs to the primary teeth in this period, it can affect the aesthetics of the permanent teeth, which will present at approximately eight years of age with whitish marks or a deformation in the crown depending on the extent of the injury.

The most serious lesions on the primary teeth can cause complications to the permanent successors; ie. intrusion (when the tooth is buried in the gum) and avulsion (when the tooth is knocked out). Both situations are more serious the younger the child is.

The primary tooth should not be replaced once it has been knocked out.
