Cracks are natural grooves on the chewing surface of molars. This is where food is easily trapped and creates favorable conditions for breeding pathogenic bacteria. So this area is often the place where caries form the most.
To prevent the development of caries in this area, you can refer to fillings. This procedure involves cleaning and then filling the crack with a unique substance. After filling, what will reduce the number of bacteria in the gaps?
Fillings can be done at any age and are also very quick. Talk to your dentist if you think you need a filling.
