Hello, Welcome to icliniq.com. A hole signifies that you have got caries. You might have food lodgement at the site too. I would suggest you get an X-ray to determine the extent of caries involved, and I will decide whether you need the treatment or not for the time being. Could you please get back to me and specify which tooth is involved? If possible, please send me a picture so that I can guide you appropriately.
