The difference between a light filling and a regular filling.

In most cases, a decaying tooth can be saved with a filling. The inhabitants have many questions about this procedure. For example, many are interested in how a light seal differs from a conventional one. Let's try to figure it out.

General information

Filling consists in filling the cavity formed in the tooth with a special compound. This measure protects the exposed tissue from further unhindered entry of microbes to them and allows you to restore, at least improve the appearance of the problem tooth.


The two dental products differ primarily in their composition. An obligatory component of a light seal is a substance that is sensitive to ultraviolet radiation. This type of material hardens only when exposed to a special lamp. An ordinary filling hardens directly in the air. Such drugs are different in composition. In some cases, they contain compounds with a preventive effect against caries.

The difference between light fillings and ordinary fillings is that it is much more convenient for a doctor to install the first of them. The plastic material is applied to the desired place in small portions. At the same time, the specialist has the opportunity to work calmly. After all, he himself decides at what moment to shine with a lamp, so that the next completed section hardens. Meanwhile, an ordinary filling sets quite quickly, so it is much more difficult to give it an ideal shape. You have to spend more time on grinding, which, by the way, this material is less susceptible to.

However, light filling is not without its drawbacks. On the one hand, it allows you to restore even extremely decayed teeth. On the other hand, it is not very suitable for eliminating very deep carious defects, since it is impossible to achieve the desired concentration of ultraviolet rays in hard-to-reach places. The usual composition, in turn, solidifies firmly and evenly both in the very depth of the cavity and from above.

As a rule, it is the usual filling that is placed on the molars located in the back of the mouth. But to carry out restoration in the so-called smile zone, it is best to use a light analogue whenever possible. Preparations of this type have many shading options, which makes it possible to install a completely invisible filling on the tooth.

What is the difference between light and conventional fillings when comparing their lifespan? Here it is impossible to give preference to one or another product. There are many points that matter in this matter. First, the material itself must be of high quality. Secondly, in the work it is important to comply with the appropriate technology. Thirdly, even a perfect filling will be short-lived if you do not treat it with care. As for the price, in general, dental restoration with the use of a light preparation is more expensive.
