Diseases
Retained canines in the upper jaw are relatively common. Due to the late eruption, the canine tooth has hardly any space and then appears completely outside the dental arch, from where it must be repositioned in the arch with the help of brackets and fixed braces. The bracket is glued to the crown of the tooth and the tooth is pulled into the created gap by means of bands.
Sometimes the tooth lies so crosswise in the jaw that it can only be removed surgically. Sometimes the attempt of tooth transplantation is started and the tooth is transplanted to where it belongs during the operation, but this is only possible in very rare cases. A non-attachment of the canines is not very common and almost never occurs.
A milk canine that does not want to fall out even in teenage or adult age is therefore a good indication of displaced teeth. Milk teeth are resorbed at the root by the permanent teeth and eventually fall out because of the lack of hold. If the following tooth is missing, there is no resorption and the milk tooth is preserved.
Milk teeth are smaller and bluer in color than permanent teeth. The canine teeth of the upper jaw are also called “eye teeth”. The name comes from the fact that its root reaches almost to the bony orbita (the bony orbit).
Inflammations at the root tip therefore often manifest themselves with swelling and redness below the eye. Pusty abscesses that form in the course of an untreated root inflammation can therefore break open into the orbit of the eye or massively impede vision because the eye swells up. The dentist opens the abscess carefully and lets the pus drain off. The swelling of the eye should then go down immediately.
