Often the only solution for dilapidated, decayed teeth or those in a sick environment is extraction.

Often, only extraction is possible if teeth are dilapidated or decayed, or if their direct environment is affected. The infection in the tooth is transmitted to the top of the root and the surrounding bone, causing inflammation that can cause the gum to swell, causing the tooth to move and be sensitive to touch. Inflammations of the teeth in the upper jaw can be transmitted to the sinuses. In the case of chronic inflammation (with focus of infection), when on the radio the abscess is clearly visible on the top of the root, tooth extraction is necessary. Surgical extraction 

If the tooth cannot be removed by simple extraction, then surgery is necessary. It is necessary if the caries has attacked the collar or the coronary part of the tooth, because under the forceps of the forceps, this tooth could burst. The surgical operation is necessary when the root is strongly deformed, in case of intercalated canine, in case of wisdom tooth and for the molars of the upper jaw if the root is near the sinus, running the risk of the opening of the sinus. The operation begins with local anesthesia (injection of Lidocaine 2%), then an incision is made over the entire contour of the tooth. Once the gum is spread, the bone surrounding the roots is removed, then the tooth. The inflammatory foci present in the hole left by the tooth are also extracted, then the bone irregularities around the dental socket are corrected. Finally the edges of the scar are sewn together and the operating field is thus closed.
