How A Decayed Portion Is Restored In Our Tooth?

Human tooth is made up of calcium and we all know the outer portion is strongest part enamel which easily sticks to the food particles which generates acids leads to a state called cavity. This cavity could be replaced using one of the well-known methods of tooth filling.

Why I need a replacement?

As we all know the teeth are of 3 layers enamel, dentin, and pulp. If the bacteria can penetrate through the strongest part enamel than reaching dentin and pulp won’t be a big process since they are very soft when compared to the outer part enamel. This leads to severe pain

What is filling?

They are a type of materials that are used to restore the damaged or decayed part of the tooth into its original shape and function. When a dentist decides to perform filling first they remove the decay tooth part and clean the damaged area and then goes for filling out the cavity part with the filling material.
