Complete Dentures are used when you have no remaining upper (maxillary) and lower (mandibular) teeth. They fill the mouth, held in place by muscles and suction (on the top) and muscle (on the bottom). They are made from acrylic and designed to look like healthy teeth and gums.
However, since they cover the palate (the roof of the mouth) they interfere with your ability to taste.
Complete dentures are removable which makes them easy to clean. They can take some getting used to, but, if they’ve been correctly fitted you should adjust to your dentures within a day or two.
Partial Dentures are removable and used to replace multiple missing teeth by attaching them to remaining teeth or implants.
Less expensive versions will have visible metal clasps; more expensive Partials (Flexible Partials) have hidden clasps, blending them seamlessly into the mouth.
Partial Dentures help overall chewing capability and are easier to get used to compared to Complete Dentures and they don’t block your ability to taste. They need to be removed often to relieve pressure on other teeth, and should not be worn to sleep. They’re easy to clean and maintain.
Continued improvements in implant materials and procedures are rendering dentures less common but they remain a good option for limited budgets.
