Periodontal or gum disease symptoms often do not occur until the patient may be in an advanced stage of the disease. Early signs or warnings include the following: red, swollen, tender, or bleeding gums. Also, gums that have receded causing the teeth to look longer. Loose or separating teeth can be a sign. Sores in your mouth or signs of pus or infection accompanied with persistent bad breath are another indication. Finally, any change in your bite or the fit of any dental appliances are a sign of periodontal change in health. These symptoms require an immediate evaluation with your dentist.
