A full denture is the best solution for people looking for a prosthesis that will replace all their teeth at once. Traditional full dentures are removable, sitting on top of your gums using suction to keep them in place. Lower dentures are a bit more unique, as they rely on your lips, cheeks, and tongues to keep them in the right spot. If you need to stabilise your dentures throughout the day, you can use as few as four dental implants designed to hold everything in place. In some cases, fixed hybrid dentures eliminate the need for removable dentures.
