Abstract
Aim: Halitosis is the unpleasant odor emitted from the oral cavity during exhalation and phonation. Using oral care products containing specific probiotics and paraprobiotics, combined with lifestyle changes, this study is aimed at resolving the patient's altered breath odor. Case Report: A 49-year-old male patient suffered from retronasal discharge, bacterial plaque on the back of his tongue, and bad breath. He underwent a professional oral hygiene session, received instructions in proper home oral hygiene techniques, and was advised on appropriate lifestyle changes. The use of oral care products based on probiotics and paraprobiotics was recommended. Sixty days later, the patient was reevaluated and was satisfied with the results, as his tongue had improved significantly, and he no longer experienced any bad sensations in his mouth. Conclusion: Systematic removal of bacterial biofilm and the use of probiotics and paraprobiotics can be useful in the prevention and treatment of halitosis.
