Can dental fillings be applied on primary teeth? If not filled, do they damage the permanent teeth?

– Primary teeth start to come in (erupt) at about 6 months of age and the complete set of primary teeth are formed around 2-2.5 years of age. Shortly after age 4, the jaw and facial bones of the child begins to grow, creating spaces between the primary teeth. This is a perfectly natural growth process that provides the necessary space for the larger permanent teeth to emerge. Between the ages of 6 and 12, a mixture of both primary teeth and permanent teeth reside in the mouth. The dental cavities on the primary teeth should definitely be treated. Otherwise the cavity evolves and the child feels a great pain. It also causes infection and this affects the permanent teeth. This affects the structure of the permanent tooth that erupts from the bottom and may damage the permanent tooth.
