Dental veneers are a major concern for every patient with missing teeth, as teeth are important organs for chewing food and taking in nutrients, and are responsible for aesthetic and speech functions. However, teeth are often missing in life due to various reasons. Some people do not set teeth in time after missing teeth, so that the neighboring teeth on both sides of the tilt shift and elongation of the opposite jaw teeth, which further cause food blockage and waste tartar accumulation, the oral balance is destroyed, chewing function declined. Therefore, missing teeth should be repaired in time. At present, there are several methods to repair missing teeth: 1, fixed denture: is the denture with crowns fixed on the two ends of the abutment teeth, the advantages of its small size, a small sense of foreign body, without the need for patients to take out to clean and restore chewing function is good (up to 80% of the real teeth). 2.Active denture: metal and plastic dentures are fixed to the neighboring teeth and mucosa, the advantages of a wide range of restorations, less cutting of the dentition, the price is cheaper. 3, artificial dental implants: is in the missing teeth with surgical methods, artificial tooth roots implanted into the jawbone, in the denture will be installed on the artificial tooth roots. How long will it take to set dentures after tooth extraction? First of all, it depends on whether the wound at the missing tooth is completely flat or not. Tooth extraction causes trauma to the alveolar bone and mucous membranes, and the healing process of the wound varies from case to case, usually taking one and a half to three months. If you wait a little longer after an extraction, your teeth will heal better and your dentures will be more likely to succeed. But too long after the extraction and then set dentures, there will be neighboring teeth tilt on the bite too long, at this time set teeth is more difficult, so the patient can go to the hospital about two months after the extraction of teeth set teeth, generally speaking, this is the best time for restorative treatment.
