A little over a year ago I went to have some dental work done. Growing up I had not insurance and had been to a dentist once in my 26 years. Last year it had been nearly 18 years. They were amazed I did not have even worse problems. I was able to afford half the work I needed at the time which was 4 fillings. I had a tooth that had been worked on and after about a month developed a large infection. Face totally swelled up.  Went back and they had to cut into the gum to drain. She had removed the filling and refilled it. She never mentioned to me the need to come back in the near future. About a month later I was eating a baked potato chip and part of the tooth broke off and part of the filling came out. Months later I began to notice a foul smell in my mouth and noticed the rest of the filling was loose. I tugged it out and out came a bunch of cotton stuffing that was yellow and disgusting smelling. The filling was also this porous white material which smelt just awful as well.  Ive had this huge hole in my tooth for over a year now. No problems with it as I make sure to clean it out after every eating. I dont understand if that was a normal filling or what the dentist had planned for the tooth.
Hi, Thanks for asking the query, According to your history I suspect that a temporary filling with a medicated piece of cotton was given to you whicChatDoctore out. You probably have developed pus in the tooth, foul smell is due to the food lodgment and pus accumulation.  Such an abscessed tooth is indicated for Root canal treatment to save it permanently. I would suggest you to visit the Dentist and get the checkup done, take an x-ray of the tooth. Go for symptomatic treatment of complete mouth scaling and polishing. Take complete course of antibiotics and analgesics. Maintain a good oral hygiene, use antiseptic mouth rinses twice daily. Hope this helps out. Regards.
