Hello, I have read your inquiry. My initial screening would include an evaluation for: -Periodontal disease -Ulcerating gingivitis - Heavy plaque and tartar accumulation -Fungal oral yeast infection -Changes in your salivary glands -Dental infections with drainage A review of your medical history may show changes that could affect the mouth and gums. Have there been any recent changes to your diet?Have you started to use any new products? Allergic reactions are possible. Are there changes in medications or vitamins? Do you experience a dry mouth? A recent change such as stopping smoking can change your oral environment. Do you have any gastric disturbances? Do you have any sinus congestion? These are some questions that I would review with my patients upon a clinical exam. More details would be helpful. I recommend a clinical examination. If you are not up to date on your dental exam please schedule a routine visit and cleaning. Please maintain good oral hygiene. Warm saltwater rinses have a cleansing effect. Please follow through with a dental visit if this does not resolve shortly. Thank you for your inquiry. I am available to answer additional questions and would be glad to assist you further with more details provided.
