"False teeth" is a common term used to describe dental prostheses that replace missing teeth in the mouth. However, there are several other synonyms that can be used interchangeably with "false teeth." A popular alternative is "dentures," which refers to a removable device that provides a natural-looking set of teeth. "Dental prosthesis," "dental plate," and "oral appliance" are other synonyms that accurately describe artificial teeth. "Dental implants" are another option, but these are surgically implanted into the jawbone rather than being removable. Ultimately, the choice of terminology depends on the context and audience, but these synonyms can add variety to written or oral discussions about dental health.
