Partial and full dentures might feel loose and uncomfortable for a few weeks, and they may initially cause slight soreness and irritation, according to WebMD. Once the cheek and tongue muscles adjust to keeping them in place and wearers get used to inserting and removing them, these problems should disappear.
Partial dentures generally feature one or more replacement teeth attached to a thick plastic base. Sometimes, a metal frame is also connected to the base in order to keep the denture secure when it's inside of the mouth, explains WebMD. Partial dentures are designed to fill spaces caused by missing teeth, and they also keep the remaining natural teeth from changing positions to create a more natural look.
