1.A removable partial which is a plate you take out to clean and do not sleep with it,it is most economical option and an option for several missing teeth
2. A fixed bridge which is permanent and replaces the missing tooth but needs a tooth to be an anchor on either side of the missing tooth.
3. An implant- good option for single missing tooth and good option as it does not compromise adjacent teeth. Only downside is it can be expensive and requires longer waiting period for healing of each stage, so can take a little while before you get your tooth
