You can politely tell her yourself. Mouth odour this period is not funny.

just get here mouth wash without saying anything she will understand..

A friend that can't tell you the truth isn't a true friend. Your sister shouldn't pretend as if she doesn't know her friend is suffering from halitosis. She should tell her, it's treatable.

.

Be your "sister's friend" friend.
Tell her the truth as politely as possible.

'Aunty sososo, did you change your toothpaste?, this new one is not good . Your mouth is smelling onugbu or something else'

Message has been delivered and understood!

Tell me your tribe without mentioning the tribe..🤣🤣😂😂

Help her buy toothpaste. Maybe that would indirectly pass a message to her.

nasoh I take clear one girl mouth odour that year

Let me share a story with you:

A young lady was told about her bad breath but she never knew the extent not until she went to church and sat close to their reverend during Bible study.

According to her, the reverend made a "noticeable / obvious move" as a result of her breath in the middle of the class that embarrassed her. She felt bad, left and stopped going to church.

It also helped her to realise the extent of her problem and seek solutions. The smell was coming from her stomach.

She is now on medication and building up her confidence but she has vowed never to return to her church because of the attitude of the Reverend to her medical problem.

Please, be careful what you say and how you pass your message across. The odour might be more than not brushing daily.
Thank you
