Halitosis (bad breath) is estimated to be the third most frequent reason for patients to seek dental care, following tooth decay and gum disease. Pharmacists can promote oral health and give patients advice on prevention and management of halitosis

Between 80% and 90% of offensive breath odours of intra-oral origin can be attributed to volatile sulphur compounds, produced by bacteria commonly found in the coating located on the upper posterior surface of the tongue. Pharmacists can promote oral health and advise patients on methods to prevent and manage halitosis, such as tongue scraping.
