Dear Queenie,
A friend of mine has very bad breath, so bad that it is uncomfortable to have a conversation with her closer than like across a table.
Queenie, should I say something to her about it?—Holding my breath
Dear Holding,
Yes. Tell her as sweetly as you can manage that she should see her dentist, because bad breath can be a symptom of gum disease which can cause loss of teeth and even bone loss, and can become very painful and expensive to treat.
