What is a dental teeth eruption chart?

A dental chart is a graphic presentation of the human mouth, consisting of all the teeth' lineaments and adjacent parts. Dental charts are of great significance in diagnosing and treating dental disorders for dentists.

Stages of Tooth Eruption

The breaking through of primary teeth is a progressive process that commences in the womb and ends in the teenage years. The process can be divided into several stages:



 1. Embryonic Stage

The teeth start forming inside the jawbone during the embryonic stage of development. The buccal cavity organs have already evolved to do their tasks during this stage. This stage—the sixth and twenty weeks of pregnancy—is the first significant. The teeth in this stage possess a soft epithelium known as the dental lamina. The dental lamina will eventually turn to the enamel, dentin, and cementum once the hard tissues of the teeth have developed.


2. Bud Stage

The second stage of tooth eruption starts with the bud stage, which occurs at about 12 weeks of gestation. During this period, the dental lamina becomes thicker and a little bud. The conferment of this bud will bear the crown of the tooth.


3. Cap Stage

The cap stage of tooth eruption occurs during the sixteenth week of pregnancy. At this point, the bud keeps growing and shaping, forming a round head. Finally, this whole thing remains the tooth crown. The eruption chart for teeth explains that this stage is the most important one. 


4. Bell Stage

The subsequent tooth eruption stage is the mold stage, which begins around twenty weeks. During it, the cap proceeds with its growth and evolves into a bell-like body. Soon, the tiny bell will become a root of the tooth in compliance with the eruption chart of teeth.



5. Eruption Stage

The last but one stage in the tooth eruption sequence is called the eruption stage, and it occurs immediately after a baby is born. This is the part where the root of the tooth pushes through the gum tissues and can now be seen above the gums. The placement of dentitions depends on the patient, and it generally follows an order of incarceration.
