Not every 20-year-old needs a tooth extraction. The need for tooth extraction can vary depending on many factors that occur in the tooth. For example, if the tooth develops problems such as cavities, fractures, pain or infection, extraction may be necessary. If there is only an aesthetic problem in the tooth, tooth extraction may not be necessary. In addition, other treatment options may be considered instead of tooth extraction. They should talk to your dentist to evaluate the condition of your teeth and the most appropriate treatment options.
