Three types of dental developmental anomalies exist:

Anomalies in the number of teethIn some people, there may be missing teeth (hypodontia or agenesis) or excess teeth (hyperdontia or hypergenesis). We exclude wisdom teeth here. In the first case, it is often the incisors or second premolars that are missing or will never develop. This anomaly ensures that the milk tooth does not fall out, because it is not pushed by the permanent tooth. The baby tooth can remain in place during adulthood. It is equally possible that the milk tooth may fall out without ever being replaced. This is where your dentist will be able to find a suitable treatment. If hypondontia is diagnosed early in childhood, the space can be filled with a prosthesis for implant placement later, once growth is complete. However, in adults, dentition has been established and existing teeth may have filled the gap left by the missing tooth. If this situation causes discomfort, you should consult a dentist who can provide professional advice. It should be noted that the total absence of teeth is less common (anodontia). In the second case, we are dealing with an excess of the number of teeth. It is important to have a dental and radiological examination to diagnose hyperdontia. Often, an accidental discovery of one too many teeth is made during an x-ray. Treatment consists of the extraction of problematic teeth, while ensuring that the need for orthodontics is minimized. The dentist will choose a treatment that will promote the best possible alignment of the remaining teeth. |
Shape anomalies (tooth volume)The shape anomalies concern, among other things, the crown of the tooth. The teeth then have a “rice grain” shape (microdontia) and their small size differs from that of neighbouring teeth. It is mainly the lateral incisors that are affected. It is possible to treat these anomalies with composite or porcelain veneers to obtain excellent aesthetic results. (Image source: Club scientifique dentaire) |
