Tooth development Part 1

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

Restorative treatment may be needed at some point. Continue reading

Dental care for osteogenesis imperfecta patients Part 1

Osteogenesis imperfecta (OI) is always associated with bone fragility. In addition, OI may affect the growth of the jaws and may or may not affect the teeth. About half of the people who have OI have teeth that appear normal, and their major concerns are routine care. However, the other half has a defect in the teeth called dentinogenesis imperfecta (DI), sometimes referred to as opalescent teeth or brittle teeth. These teeth may be misshapen, may chip or break easily, and will require special care. Continue reading

Eruption dates

Human beings have two sets of teeth —- Primary (milk teeth) and Permanent. There are 20 primary and 32 permanent teeth. In some people one or more teeth may be absent, or they may have some extra teeth (supernumerary). Usually the first primary teeth erupt by 6 months and the first permanent by 6 years of age. Children loose their milk teeth between 6 and 11 years of age. By the age of 13 years almost all the permanent teeth have erupted: 8 incisors, 4 canines, 8 premolars and 12 molars. The last 4 molars commonly known as wisdom teeth appear much later, between 18 to 21 years. The main function of your teeth is to chew and cut food. Anterior teeth are used to bite and tear food while the posterior teeth help in chewing. Hence your dental health is an important part of your general health and your overall well-being.
