Partial dentures sound exactly how they look. Instead of having an entire set of new teeth, partial dentures replace missing teeth with artificial teeth to give you a complete smile. Partial dentures are artificial teeth fixed to a pink gum-like base that clicks into your upper or lower jaw.  Like a retainer, they are removable and can be easily cleaned and can be an alternative to implants. They are a solution if most of your natural teeth can be kept in a healthy condition.
