Final answer:
Severely decayed and endodontically treated primary teeth are treated by a dentist with restorative procedures including fillings or crowns, depending on the extent of damage and decay.
Step-by-step explanation:
The dentist will treat severely decayed and endodontically treated primary teeth with restorative procedures such as fillings or crowns.
When primary teeth are severely decayed and have undergone endodontic treatment, typically a root canal, a dentist will proceed to restore the teeth. This involves removing all decay and damaged tissue, ensuring the affected areas are thoroughly cleansed to prevent the spread of infection. In smaller cavities, a simple filling may suffice.
This procedure involves covering the tooth with a protective cap, restoring its shape and function. Microbes such as Streptococcus mutans substantially contribute to tooth decay by producing acids that erode tooth enamel and dentin. These restorative treatments are crucial to ensure the longevity and health of the primary teeth until they naturally fall out to make way for permanent teeth.
