Hello, I will refer my patients to the periodontist for treatment of advanced periodontal disease or unresponsive tissue conditions. A change in tissue in color usually indicates a state of inflammation. Typically there is some swelling of tissue inbetween the teeth. Periodontal disease does not always warn patients with pain until an abscess or extreme amount of bone is lost. Lower front teeth may experience stress resulting in recession and loss of attached tissue. The attached tissue is the firmer tissue band that should surround and protect your teeth at the gum line. Did your dentist refer to mucoginigival concerns? Do you have bleeding, loose teeth or did the dentist mention probings? I recommend that you schedule your visit with the periodontist. You should plan on taking or having available a full set of x-rays. Your medical history and habits will be reviewed and considered in your evaluation. This specialist will recommend your needed treatment. You can relax and maintain good daily oral care and a balanced diet. Make sure that you do not have any vitamin deficiencies. Thank you for your inquiry. I am glad to assist you further if you have additional details to share with me.
