The objective of a devitalization is to empty the living substances contained inside a tooth.
The dentist will remove the pulp of the tooth, blood vessels and the nerves, that's why we talk about devitalization.
Devitalization is also called root canal treatment (in relation to an organic canal) or endodontic treatment (in relation to the tooth tissues).
Devitalization becomes necessary when the tooth decay is deep in the tooth, that is to say, when the caries attacked the pulp. Caries first attack the tooth enamel then the dentine to finally get to the pulp.
When the pulp is affected, the risks of inflammation and necrosis are high. This is also what causes toothaches.
Devitalisation thus serves to prevent the spread of such an infection to other parts of the body through the bloodstream.
It is also possible to have to devitalize a tooth following a trauma, such as a fall or an accident, which would have resulted in the fracture of one or several teeth. In fact, when the teeth are broken in half, the living part (pulp, nerves ...) may become infected from exposure to air and various chewed food.
Devitalization is generally in this case, the first step of the insertion of a post and a crown.
The dentist will initially remove the infected tissue inside the tooth. Following this procedure, a disinfection of the interior of the tooth is required, then the empty hole in the tooth is filled with an antiseptic root canal filling material and a filling to restore the anatomy of the crown.
The tooth remains in the arch, it is simply inert. However, the tooth is weakened by the devitalization because it is no longer alive. This can lead to higher risks of breaking and color change.
It is therefore widely planned to place a post and a crown to protect it and avoid the inconvenience of an aesthetic order.
