It feels like I have something wedged between my back molar and my gum, or perhaps its a hole or something?  It just feels strange when I run my tongue across it.  But Ive tried flossing and nothing seems to be stuck?  And it looks fine when I look in the mirror.. What is this?
Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have feeling wedge in between gum and molar tooth this wedge can be due to periodontal problem may be due to formation of Periodontal Pocket or due to Caries also This can be confirmed by radiograph evaluation visit dentist and go for investigations X-ray. If it is due to periodontal problem go for Curettage and if it is carious then go for Restoration. Do warm saline gargle two - three times a day. Do chlorhexidine mouthwash twice daily. Hope this will help you.
