Premature shedding of milk teeth

Throughout the life cycle of a person's teeth twice consistently change. The initial replacement of teeth is called dairy or baby teeth. For dentists, the name is usual as primary, incised or unstable teeth. After the loss of milk teeth, in their place eventually grow up indigenous. However, sometimes parents may face such a problem as premature loss of baby teeth.

The timing of non-permanent teeth

Lower jaw: central incisors - at the beginning of the second half of the year, lateral - 7 months, the fourth in a year or year and four months, fangs to about 20 months, fifth teeth a year and eight months and up to two and a half years. Upper jaw: central incisors 7.5 months, lateral at 8 months, fourth teeth per year and up to 16 months, fangs from year and four to year and eight months, fifth to 30 months.

Cause of non-permanent milk teeth

Loss of milk teeth begins with the beginning of the growth of permanent teeth. The process of loss of primary teeth is caused by the resorption of the roots of the dairy, that is, the root gradually dissolves.

With the germination of a permanent tooth that passes through the jawbone directly to the soft tissues of the jaw, the root of the proper primary tooth becomes smaller and smaller. And as a result, the root of the milk tooth can not hold it in the cavity any longer and the tooth freely separates from its place.

The effect of premature loss of primary teeth on the growth of permanent teeth

One of the significant functions of the milk teeth is the place indicators for the second shift, i.e. permanent teeth. In the event that the child, as it develops prematurely, drops out the milk tooth and does not retain its place, then in the future the permanent teeth that come to replace them may be twisted or their growth may become difficult.

Premature loss of primary teeth can cause permanent teeth to grow uneven. Consider an example of premature falling out of the second molar tooth of a child.

With a normal growth of teeth, i.e., a normal change of non-permanent teeth to permanent teeth, there must be a resorption of the roots of the primary teeth. Root resorption frees the place for the next permanent tooth and shows it the right place for its location in the dentition. In addition, if the primary second molar was available before the end of the eruption is permanent, then finding it on the spot helps to ensure a permanent and correct place for the permanent tooth.

But if the second milk molar has fallen prematurely at the initial stage of the change of teeth, its function of indicating the location for permanent location is not manifested. Because of this, the permanent first molar tooth will search for a suitable new location and begin to move to the center of the free space. As a result, a small molar tooth can generally remain without its proper place or there will be difficulty in erupting a small molar tooth, since it can not easily pass through the gum tissue.

To replace the point of indication, dropped out before the deadline of the tooth, use a special device.

If it is impossible to avoid the removal of the milk tooth at an early stage of permanent development and it is necessary to save space for the next permanent tooth, the dentists use the device - the holder of the site of the removed tooth. This device is attached to one of the teeth on the side where the tooth was removed, and from the second end the device is held with a wire on the tooth from the opposite side of the empty space. With the help of this method (retaining the place of the socket of the prematurely removed tooth), there remains a place for the subsequent growth of the permanent tooth and adjacent teeth will not move, occupying someone else's place. It helps the correct appearance of permanent teeth and the occupation intended for them. Such a device will help to avoid further intervention for the correction of teeth, such as braces. This holder is removed as soon as the perforation of the permanent tooth through the gum becomes evident.
