Under normal circumstances, babies will have their first baby tooth at around six months of age, and all twenty baby teeth will come in at around two and a half years of age. However, there is a great deal of individual variability in the specific timing of each baby’s teething, with the earlier ones growing their first teeth at around four months, and the later ones erupting their first teeth at around ten months. Teething in a four-month-old baby is a normal phenomenon and is not a cause for concern. However, there is a clinical need to rule out the possibility of horse teeth growing on the gums. Horsetooth is the product of the dental plate in the process of development, left behind, in the form of a great difference with the normal teeth, however, the color is closer to the normal teeth, some parents can not distinguish between horsetooth and the real teeth. Special attention should be paid to the fact that horse teeth will fall out on their own within a period of time, and after that, the subsequent teeth will erupt normally.
