The correct term for tooth decay is caries, and the price for caries extraction is usually around $100~300, and if the decayed tooth is an obstructed wisdom tooth, it may cost around $300~600, with additional costs if subsequent restorative treatment is required. Extraction of caries is suitable for those whose dental tissues are severely decayed and cannot be restored and utilized by existing restorative means, such as those whose teeth have too large a range of caries, with 3~4 axial wall defects or defects that reach deep to the subgingival area, or whose remaining roots are too short or curved, or those who have periodontal disease or periapical disease. Fixed partial denture restoration, implant denture restoration, removable partial denture restoration can be chosen after caries extraction to restore the form and function of missing teeth. It is recommended to visit the hospital for professional treatment.
