The term “permanent dentures” is deceptive and misleading. As we know, most things in life are not permanent, teeth and dentures alike. “Permanent dentures” are retained by screws or dental cement onto dental implants and cannot be removed by a patient; they can only be removed by your denturist. Eventually even these “permanent dentures” may wear or break or become stained and discolored and will require replacement. Typically, soreness should be resolved within two weeks; if it persists, likely something in the denture needs to be adjusted. You should see your denturist as soon as possible.
