On average, a full set of dentures contains 32 teeth, which is the same number of teeth that are in a natural adult mouth. However, the number of teeth on a denture can vary depending on the patient's needs and preferences. Some people may opt for partial dentures that replace only a few missing teeth, while others may require a complete set of dentures to replace all of their teeth. Always work alongside your dentist to decide on the best type of denture for your needs.
