What are dentate ridges on the edge of permanent teeth in children?

If you look closely, you can see that the winning surface of the permanent front teeth in children is serrated. Sometimes parents, when they first notice these toothed bumps on the edge of their child’s teeth, think there is a problem and that these teeth are caused by breaking or grinding.

You should know that the jagged edges of permanent teeth are completely natural. In fact, these indented ridges, called Mamelons, are related to the way permanent teeth grow, and all teeth look like this in the beginning.

In the first growth, the part of the tooth bud of the previous teeth that causes the growth of tooth enamel, is composed of three separate foci that these three foci are connected during the tooth growth process and the teeth that are on the edge of the front teeth. They are actually created due to the merging of these parts.

All teeth grow from something called the lobe, which is deep inside the gums. Different lobes grow together and each forms a different part of the tooth. In the case of front teeth, there are three lobes that together form the front of the tooth. By looking at dental mammals, you can see where these lobes meet and connect. There is a front lobe on the left, one in the middle and one on the right, which form a tooth as it grows and reaches each other.

Why are the edges of the front teeth not serrated in adults?

These ridges are usually seen for a short time and disappear very quickly. Because these teeth are not even and thin, they are quickly eroded and destroyed by chewing food. However, it is interesting to know that in some people these teeth remain for a long time.

In some adults, whose front teeth do not come together and do not make proper contact, mammoths remain. For example, if a person has open bite or overjet and the edges of his upper and lower front teeth do not come in contact with each other, the mammoths of the opposite teeth do not come in contact with each other and are therefore preserved. Adults who have not yet lost their teeth and do not like the appearance of it, can go to the dentist to have a cosmetic treatment (enamel shaping) to smooth it. As we age and wear the edges of the upper and lower teeth on top of each other, the depth of these teeth, which are in the enamel area, decreases and the teeth look smoother. This condition is completely normal on the front teeth and will not harm the person. However, in situations such as the front of the upper jaw or the back of the lower jaw, we will not see wear and smoothness of the edges of the teeth. Some habits in people may cause deep indentations or grooves in the anterior teeth, which deepen over time.
