The teeth and milk molars, like the permanent ones, have a series of functions to fulfill: chewing (incising, cutting, grinding), supporting the pronunciation of certain sounds, and also a social function, since they intervene in the smile, in the self-esteem.
It will surely be unfair, but when we see a child with black teeth in line at school, it doesn't make a very good impression on us. Finally, baby teeth are saving the space that permanent teeth will need.
When a baby tooth develops a cavity, not only can it be should be arranged, as far as possible. Filling a tooth consists of removing the tissue in poor condition and replacing it with an artificial material that allows the tooth to continue performing its function. It is surprising how the hardest tissue that exists in the body, much more so than bones, remains with the same soft and sticky consistency that bread crumbs have when attacked by bacteria.
After cleaning, we place an artificial material in a deformable state (such as plasticine) and that it remains hardened in that hole that we have previously cleaned. Normally they harden thanks to the light emitted by a special lamp.
The technique used will vary depending on how much tooth has been lost and the age and collaboration of the little patient. In very young children, techniques are performed that the WHO recognizes as ART or (TRA in Spanish, 'atraumatic restoration techniques'), which consists of cleaning with a very small instrument called a spoon, without a turbine ('lathe'), and without anesthesia because by cleaning manually we avoid all the annoyances that the use of rotary instruments implies. That is, we 'scratch' the tissue in poor condition and it is not necessary or anesthesia, nor the wheel or sprays with water, things that make young children very uncomfortable.
We place a glass-cement-based material, which has the advantage that it releases fluoride at the boundaries between the filling and the tooth, thus making it difficult for new cavities to emerge around the filling. But these restorations can never be considered permanent. They help to slow down the progress of cavities, but they do not restore anatomy or aesthetics, something that can be achieved in older children.
In older children it is necessary to anesthetize because we are going to enter deeper areas of the tooth. We are going to try to clean much better, we need more working time and better conditions. The material used is normally composite, which is inserted in layers inside the tooth and each layer is hardened separately with the lamp.
Anyways a decayed tooth or a filled tooth are risk factors for future cavities. A visit to the dentist every 6 months is essential to ensure that cavities do not develop. The sooner they come out, the worse their prognosis.
