Whether a tooth can be extracted in case of toothache needs to be judged according to whether there is inflammation or not, and cannot be generalized. If it is caused by inflammation, such as pulpitis or periapical inflammation, or if the gum swelling is more obvious, the tooth cannot be extracted. Because tooth extraction at this time will lead to the spread of inflammation and easily lead to facial swelling and other infections, so it is necessary to carry out anti-inflammatory treatment first, and then consider whether it is necessary to extract the tooth after the inflammation is under control, and this type of toothache can usually be cured by root canal treatment, etc. In time, without tooth extraction, it will not affect the chewing function. If there are cavities in the teeth or wisdom teeth growing in the wrong position or periodontitis causing severe loosening of the teeth, the teeth can be extracted. After tooth extraction, you should rinse your mouth more often to keep the traumatic surface clean. In daily life, you should master the correct way to brush your teeth, don’t touch your teeth or chew harder food with your teeth often, and go to dentistry for dental care once every six months to a year.
