when do the primary teeth fall down?

The milk teeth begin to form in the third week of intrauterine life, so that When the child is born it already has the germs of the 20 temporary or “milk” teeth and the differentiated cells that will give rise to the 32 definitive teeth.

From three to six years it is important that children follow a varied diet and chew food well so that the change from temporary teeth to definitive. These have a slightly more yellowish colorhence the first teeth are called “milk”.

When do the permanent teeth come out?

At the age of 6, changes begin to occur in the teeth. of the child. The lower incisors begin to move, fall out and the permanent ones appear.

He first molar erupts at 6-7 years without any teeth falling out; second molar erupts at 12-13 years old; and the third molar or wisdom toothat 18-21 years old.

This period is called Mixed dentition as there are primary and permanent teeth.

when do the primary teeth fall down?

It will depend on how they erupt the definitive teeth, which appear approximately:

The lower central incisors come out at 6-7 years The upper central incisors, at 7-8 years The upper lateral incisors, at 8-9 years The lower lateral incisors, at 7 -8 years The lower canines, at 9-10 years The upper canines, at 11-12 years old The upper first premolar at 10-11 years The lower first premolar, at 10-12 years

These data are indicative and may vary depending on the development of the childif you are used to chewing hard and crunchy foods (which favors the change), if you have space in your mouth or if you are missing teeth (agenesias are becoming more frequent).

What happens if the final teeth come in before the milk ones fall out?

The final teeth are larger, so sometimes they do not fit and come out from behind of the milk ones.

This does not cause any problem unless the child rubs his tongue. It is better to wait for the tooth to fall out on its own. and the tongue pushes the final tooth into position.

At the same time it happens that the teeth of the 6 years or first definitive molars are beginning to eruptwhich appear behind the last milk teeth, without any falling out.

Sometimes this situation goes unnoticed by both parents and children, but the gum can become inflamed and the new tooth can damage the other jaw with its cusp. It is important to detect it in case children do not chew correctly, in addition to rule out the existence of cavities between the milk molars.
