Stinky teeth are a result of food being left in between the teeth for too long, causing bacteria to break down the food and create bad breath. Be sure to take self-care by flossing after meals, using a toothpick to remove it or using an interdental brush, all of which are relatively easy and effective methods. A lot of stuffing between teeth is caused by periodontal problems, which may continue to cause inflammation of the periodontium, leading to receding gums, gingival papillitis and possibly aggravating periodontal disease. Therefore, if this happens, one should go to the hospital as soon as possible for an examination to discover the cause of food stuffing in the teeth and to carry out the corresponding treatment. Patients should also take care of themselves in daily life and not let food stay in the gap between their teeth for too long.
