If there is no filling after extraction of a large tooth may affect the occlusal relationship, dental disorders, affect pronunciation and other consequences. 1. Occlusal relationship: after extracting a big tooth, if no filling is done, the teeth on both sides will be tilted to the side of the gap, and the teeth on the opposite jaw will be extended to the opposite side due to the lack of occlusal relationship, which may eventually bite into the mucous membrane of the gums on the opposite jaw, which will cause occlusal disorders of the teeth. 2. Dental disorders: If the teeth are extracted and not filled in time, the teeth on both sides will be tilted to the center, resulting in dental disorders. In addition, if the teeth are missing, it is easy to cause food blockage, which can easily lead to tooth decay and periodontitis. 3. Impact on pronunciation: missing teeth will also affect pronunciation and other teeth. Teeth are auxiliary organs for pronunciation, and missing teeth, especially missing incisors, will affect the patient’s pronunciation and lead to slurred speech. If a large tooth has been extracted, it is recommended to go to the hospital in time to fill the tooth to repair it. Fillings can be made using a removable denture or fixed denture or implant denture.
