As mentioned before, periodontal disease is usually painless. However, there are certain signs that do occur that can signal a problem. Bleeding gums, during eating or brushing, can be a sign that periodontal disease is present. Swollen tender gums, receeding gums, persistent halitosis (bad breath), loose or separating teeth, a change in the bite or change in the fit of prosthesis are also other potential signs of this problem.
If you have experienced any of the above symptoms, do not ignore it.
