Direct fillings

To cut the long story short direct fillings are made on the spot by the dentist. A well-known type is the tooth-colored direct filling that is hardened with light.

Tooth-colored direct fillings

Tooth-colored direct filling is one of the most wide-spread types of fillings that are hardened with light.

After removing the decay the filling will be placed into the prepared tooth and will be fixed by sticking. According to age and depending on the size and location of the decay it is recommended to use different types of tooth-colored fillings for molars and front teeth. This is due to the different cosmetic expectations and different load-bearing capacities in the case of different teeth. So in the case of front teeth fillings we should use aesthetic tooth-colored direct fillings – their load-bearing capacity is lower but it is enough for the reduced occlusal pressure in this area. However in the case of molars we have to consider the load-bearing capacity first and we have to use an adequate type of filling material to achieve this. This is less aesthetic than the filling material used in the case of the front teeth, but it can be hardly seen so it doesn’t have an aesthetic disadvantage.

However in the case of all tooth-colored direct fillings we have to consider the so-called setting contraction that has a bad influence on durability. As a result of this phenomenon a gap is formed between the new filling and the tooth and its size depends on the size, extension of the cavity, on the quality of the filling and on the filling technique. The small gap is not visible but it can be easily reached by the bacteria that cause tooth decays and so they can form a decay between the filling and the tooth. Warning signs of a subdecay: appearance of a line at the edge of the filling that is at first yellowish, than brownish and it keeps getting darker and darker.

Advantages: it is very aesthetic and it can be made on the spot.

Disadvantages: limited durability.
