Extraction of deciduous teeth

deciduous teeth extraction

The life of a temporary tooth is limited. Its fall is physiologically governed by dental root resorption phenomena, and its purpose is to be replaced by a permanent tooth. Thus, the temporary tooth is the only organ to be replaced by another.

The deciduous teeth play a very important role in the oral function: chewing or preparation of the alimentary bolus, immobilization of the mandible during swallowing. They also participate in the phonation and undoubtedly to the aesthetic aspect of the face by making pleasant smile. In addition, they are essential for maxillofacial growth.
These forces us to consider the great impact of deciduous teeth extraction in children.
Unfortunately, some local and general indications such as caries and its infectious complications, trauma..., force us to extract the temporary teeth before their physiological fall. This situation often leads to complications.
In this article, we will see when to extract the deciduous teeth, when to keep them and the consequences.

When to extract deciduous teeth ?

Many situations require the extraction of temporary teeth:
In orthodontics, it is sometimes necessary to extract some temporary teeth if the space is too limited or if the eruption direction of the final teeth is abnormal. The goal is to promote the eruption of definitive teeth in the best conditions.
The extraction of temporary teeth is indicated in case of periodontal diseases. These diseases affect the gum and sometimes the bone, and create an environment where it is impossible to heal the tooth. Therefore, the dentist will have to extract the temporary tooth.
Some caries complications indicate the extraction of these teeth. Among the complications: Cellulite, abscess, cyst. The extraction is justified also in the case of a severe trauma, dental anomaly of genetic origin or if the tooth treated is not restorable.
The indications just quoted are all local, which means that they concern just the oral environment, there are indeed general indications that depend on the health state of the child.
Among these general indications there is the failure of the immune system, cardiovascular problems, diabetes. These conditions require a short treatment which is the extraction in order to avoid the risks of remote infection.

When not to extract deciduous teeth ?

Temporary teeth play a double role, on the one hand in the oral functions, on the other hand in the growth of the face and the maintenance of the space for the definitive teeth. Without them, there is no function, therefore no growth. Thus, dentists and orthodontists seek to preserve them as long as possible until their normal date of fall.
These teeth must be preserved if there is a way to heal and restore them with an organic material or prosthesis.

What are the consequences of deciduous teeth extraction?

Considering the important role of temporary teeth, their extraction may be accompanied by complications depending on the extracted tooth. The extraction of the anterior teeth will cause phonetic disorders and pronunciation problems, because the anterior teeth participate in the emission of certain sounds such as "D" "T" and "L". The anterior teeth also participate in swallowing, they serve as a support for the tongue to send the alimentary bolus to the esophagus, not to mention the psychic disorder due to the alteration of the self-image.
Extraction of the posterior teeth will cause masticatory disorders in addition to occlusion problems at the origin of inter-dental and inter-maxillary disharmony. The contact between the temporary molars serve to stabilize the mandible, in the absence of these contacts, it will adapt to the situation by modifying its growth and position, hence the problems of bad occlusion.
