Depending on the number of missing teeth, 70-somethings can choose between removable partial dentures, fixed dentures or dental implants. A doctor’s visit is required to make a definitive diagnosis as to which is the best option. 1. Removable partial denture: it is mainly used when most of the teeth are missing or the free ends of the teeth are missing and cannot be fixed, which is a common restoration method for the elderly; however, it is inconvenient because it has a sense of foreign body and needs to be taken down regularly for cleaning. 2. Fixed denture: it is mainly suitable for individual tooth loss, and there are natural teeth on both sides of the missing teeth, which has the characteristics of comfort and aesthetics; however, it is not suitable for most of the missing teeth or teeth missing at the free end. 3. Dental implants: they are suitable for all kinds of missing teeth symptoms and have comfortable and durable characteristics; however, they require healthy periodontal tissues, and dental implants for those who are too old or with systemic diseases need to be cautious. Therefore, it is recommended that 70-year-olds with missing teeth should seek medical advice and choose the appropriate restoration method under the guidance of the doctor, which is more conducive to the restoration of oral function.
