The bell stage is known for the histodifferentiation and morphodifferentiation that takes place. The dental organ is bell-shaped during this stage, and the majority of its cells are called stellate reticulum because of their star-shaped appearance.
Tooth development or odontogenesis is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth. Although many diverse species have teeth, non-human tooth development is largely the same as in humans. For human teeth to have a healthy oral environment, enamel, dentin, cementum, and the periodontium must all develop during appropriate stages of fetal development. Primary (baby) teeth start to form between the sixth and eighth weeks, and permanent teeth begin to form in the twentieth week. If teeth do not start to develop at or near these times, they will not develop at all. Continue reading →
The process of teething often follows hereditary patterns, so if the parents teethed early or late, your baby may follow the same pattern. However, the most babies have their first teeth come in when they are between 4 and 7 months old. In rare cases, a baby’s first tooth is visible at birth. We call this kind of teeth as neonatal teeth. Those teeth that emerge through the gum during the first month of life are called as natal teeth. Rarely, their presence is just one of several unusual physical findings which make up a syndrome. If the possibility of a syndrome exists, consultation with a pediatrician and/or geneticist can be helpful. The tooth is often loose and is commonly removed prior to the baby’s hospital discharge to prevent aspiration into the lungs. It is good to mention about teething during prenatal counseling because it most likely will be the first postnatal oral issue that parents confront. Continue reading →
