When the permanent teeth appear, sometimes they are positioned in a disorderly manner against each other. This bad position of teeth can cause problems that go beyond aesthetics: a voltage in the muscles of the jaw, discomfort for brushing with an increased risk of caries and gingivitis, difficulty speaking or chewing, among others.
Thumb sucking too long can distort the palate and contribute to bad tooth alignment.
These disorders require orthodontic treatment (which means "right tooth"). Depending on the severity of the situation, treatment may involve placement of a dental appliance for several months or even several years. This mobile device or landline applies a force on one or more teeth and forced to move for align. In some cases, the orthodontist must remove one or more teeth before putting the device.
The usual age for putting orthodontic device is about eleven years, when the child is still growing, he is old enough to understand the importance of treatment and the number of permanent teeth is sufficient. Nevertheless, one device may be installed from the age of seven years or in adulthood. Note that this type of care is no longer reimbursed after the age of sixteen.
