The number of teeth you need for dental implants depends on your individual case. A single missing tooth can be replaced with a single implant and crown, while multiple missing teeth can be replaced with multiple implants and a bridge or denture. If you are missing all of your teeth, a full arch of teeth can be replaced with a series of dental implants and a denture.
In general, dental implants can be used to replace any number of missing teeth, from a single tooth to an entire arch of teeth. Your dentist or oral surgeon can evaluate your individual case and recommend the best treatment plan for you.
