Pulpitis cannot be treated by tooth extraction. Initially, pulpitis involves an inflammatory response in the pulp tissue. Extracting the tooth at this stage can cause the inflammation to spread throughout the body and, in severe cases, can lead to sepsis. Therefore, it is absolutely necessary to avoid tooth extraction during a pulpitis attack. However, dental treatment can be performed during a pulpitis flare-up. Firstly, the acute pain in pulpitis is caused by increased pressure within the pulp. The primary method involves performing a pulpotomy to relieve this pressure. Once the pressure is alleviated, root canal medication can be applied, followed by root canal filling to complete the root canal treatment and preserve the tooth.
