The first babies' teeth are the milk teeth, they start to grow from 6 months. This milk tooth is made up of different teeth, including the molars.

The characteristics of babies' molars

The molars in babies' baby teeth are similar to other temporary teeth. The first molars grow in around 12-18 months, after the incisors appear. Then the second molars develop between 25 and 33 months, after the canines have grown in.

Because of their larger size, the eruption of molars is often more painful than that of other teeth.

The molars are larger teeth, with a cubic shape and rounded corners, they have an important role in chewing and grinding food. They also have a function of posterior wedging of the mandible, preventing it from sliding forward.

Around age 6, a first permanent molar begins to grow. This permanent tooth comes in addition to the 20 temporary teeth. Its eruption is therefore not preceded by the fall of a baby tooth. This first permanent molar appears behind the last temporary molar.

The first permanent molar, which appears around the age of 6, is a very important tooth, but very fragile. It is quickly decayed because it is often difficult to access. It is therefore important to pay attention to tooth brushing from childhood.

In addition, you should not hesitate to make regular appointments with a specialized dentist to prevent any risk of cavities and to check the good health of your child's teeth.
