The first teeth begin to come out from the 6th month. In this period, babies may be restless. In the first period of the first tooth, itching sensation occurs in the mouth of the baby and the amount of saliva increases. It is recommended to perform the first doctor examination after the first tooth starts to come out and before the 1st year. The dentist controls the baby’s teeth, jaw, mouth and palate, and the baby’s ability to bite.
