The correct term for root infection is periapical periodontitis, which is usually not treated by medication, but usually opts for root canal treatment, which includes root canal preparation, root canal disinfection, and root canal filling, as described below.
1. Root canal preparation: professional instruments are used to remove the infected and necrotic pulp tissue and prepare the root canal into a shape that facilitates flushing and filling.
2. Root canal disinfection: The microorganisms and toxins in the root canal system are completely eliminated with medication, commonly used medication is calcium hydroxide.
3. Root canal filling: The root canal is tightly filled with a root canal filling material to isolate the root canal from the oral cavity or periapical tissues, promote healing of the periapical lesion, and prevent reinfection.
It is recommended to go to a regular medical institution to receive professional treatment.
