While you’re brushing or flossing, you may notice warning signs such as red, swollen or tender gums. You may also notice bleeding gums. It’s important to note that there may not be any discomfort until the disease has reached an advanced stage – and that’s another reason why it’s so important to visit your dentist regularly for cleanings. Your dentist will monitor your oral health and help you identify and prevent problems before they become more serious. Additional warning signs that you may have periodontal disease include: Gums that are pulling away from your teeth (receding gums) Teeth that are loose or separating from each other Persistent bad breath and/or a bad taste in your mouth A change in the fit of partial dentures, if you wear them
