Kids
The first visit to the orthodontist is recommended at the age of 7-8 years, because at this age problems related to the jaws and/or dentition can already be diagnosed, since usually some permanent teeth have already emerged.
Early diagnosis does not necessarily mean that treatment will begin immediately, but it is very important, because with proper planning it can facilitate the treatment of an orthodontic problem. Especially when the problem is located in the jaws, it can be treated most effectively during and before the child's skeletal development is complete.
In any case, the orthodontist is able to identify the problem that exists and direct you accordingly, in terms of timely and correct intervention, in order to prevent or treat incipient orthodontic problems.
Orthodontic intervention in young children is targeted for the specific problem that will be diagnosed, in order to have the shortest possible duration and discomfort for the young patient. In practice, this means that the following are used orthodontic mechanisms (mobile or fixed) that do not necessarily include all teeth or both jaws, because we focus on the problem that concerns us directly.
Indicatively, if you notice crooked teeth, large gaps between teeth, "chipped" teeth, baby teeth that have been lost early, permanent teeth that are slow to appear in the mouth, asymmetry when closing the mouth, then your child needs to see an orthodontist. See the most typical ones early signs of orthodontic problems.
Since all children should visit the dentist or paediatric dentist for preventive reasons as soon as the first baby teeth emerge, you should also consult your colleagues who may be the first to detect an orthodontic problem.
