Instead of using "halitosis" in a sentence, you could consider alternative ways to address the issue, such as:
* "Your breath smells a little strong."
* "Have you considered using mouthwash?"
* "I'm noticing a bit of an odor coming from your mouth."
* "Maybe you should see a dentist to check on your oral hygiene."
Remember, it's important to be tactful and understanding when discussing someone's breath.
