What Causes A Pus Filled Bump On The Gum?

I have a small bubble on my top gum. I doesn't hurt all the time just sometimes. When I push on it pus come out and it smells and taste really bad. I have been telling my dentist for a year that I've had a cavity but he says he can't see one. Any idea what this could be?

Thanks for your query, I have gone through your query.
The bump on the gum could be because of the tooth infection secondary to the decay or it can be secondary to gum infection. Consult a oral physician and get it evaluated and take a radiograph to rule out tooth or gum infection.
If it is gum or tooth infection You can take a course of antibiotics and analgesics like amoxicillin 500mg and metronidazole 400mg tid for 5 days(if you are not allergic). After taking antibiotics you can get the tooth treated with RCT(if bone support is fine) for tooth infection.
if it is gum infection then get your teeth cleaned once and maintain the oral hygiene. If needed grafts can be placed to make the tooth firm.
Do saline gargling.
i hope my answer will help you, take care.

helloo...read through ur query...accordingly i must say that it can be due to pus in the gum(periodontal abscess)due to reduced oral hygiene...it can be also due to decay of tooth(we have to cancel that as ur dentist couldnt find any cavity)but nothing to be worried...do salt water gargle..use listerine mouthwash...brush twice daily..also take amoxicillin+metronidazole(doses as prescribed by ur dentist)...meet a periodontist and take an xray(if required).and get it treated based on clinical presentation..be cool..its just a common prob...nothing to be tensed..hope ur benefitted something from this reply..have a healthy day!!
