It's casued by bacteria or cavaties.
I work in the dental field and if you havent had your teeth cleaned within the last six months its probably just bacteria. The back teeth are the hardest to reach yourself. I wouldn't worry too much just call your dentist and get in for a cleaning and make sure your getting it done by the hygeinest not the actual dentist. Good Luck
I go to the dentist every 6 months. I even complained about the bad breath and all the dentist said was to brush more often. I've used every mouthwash, toothpaste, floss that has been out there. Thanks for the advise anyway :(
there is a mouth wash you can use for bad breath ask you dentist next time you go I cant remeber the name
It sounds like the two teeth are a food trap. Even if you floss every day, if you have a food trap it can be pretty stinky. If those teeth in the back have existing fillings, maybe it is time for them to be redone. If there are no fillings and the teeth don't have any cavities, leave it alone. Just keep flossing after every meal.
Try "SMART MOUTH" mouthwash. You can get it at Walgreen's. It's about $10. I had the same problem...floss then use it, it REALLY WORKS!!!!
