<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I have just noticved a small indentationhole in my gums immediately below one of my bottom front teeth, my teeth are in decent condtion although I have noticed a slight change in the health of my gums which im not sure is the start of receeding gums, at the moment Im more worried about this indentationhole. Would you have any adive as to what it could be besides goign to see a dentist, by the way it doesnt hurt.  <response>: Hi, Thanks for writing, A hole in the gingival can be a sinus opening, but for that infection has to be present nearby. As you have stated the condition of your teeth are decent, so it can be a reason due to your gums. Oral prophylaxis scaling will be required to improve your gums condition. A diagnostic x-ray and a clinical examination will be required to reach to any confirmed conclusion. Maintain your oral hygiene well, brush twice daily, use a mouthwash along. Stay healthy, Thank you.
