Common Signs of Dental Disease and Dry Mouth

Signs of Dental Disease

If the older adult is not brushing or flossing, and there seems to be no physical limitation to prevent this, perhaps there is tooth decay or gum disease present. If the individual is able to cognitively understand your questions, ask if there is mouth pain. Some indications that there is tooth or gum pain can be:

  • Verbal complaints or visible expressions of pain
  • Visible tooth decay
  • Persistent bad breath
  • Stained teeth
  • Filmy or dull looking teeth
  • Bleeding gums
  • Swelling in the mouth
  • Difficulty chewing
  • Not eating
  • Dentures are not in the mouth
  • Dentures that don't appear to fit
  • Loose teeth

If the person has Alzheimer's or another form of dementia, he or she may not be able to tell you that there is pain. Caregivers – wearing protective gloves and if necessary, a surgical mask – can carefully examine the individual's mouth for some of the following signs:

  • Visible tooth decay

  • Red or swollen gums
  • Loose teeth
  • Dry or cracked lips
  • Mouth or tongue sores
