Your text is clear and vivid, but if you’d like, I can help polish it for better flow and clarity. Here’s a slightly refined version:
Although many people experience small white balls at the back of their throat that often get coughed up into the mouth, this widespread condition is rarely discussed, and awareness of it remains low. Many suffer in silence, believing they’re alone or mistaking these for mere remnants of last night’s dinner. Another reason people don’t address their problem with tonsil stones is that they’re embarrassingly unpleasant and produce a foul smell.
If you want, I can offer other variations (more formal, casual, concise, etc.)!
