My daughter had this, we changed her toothpaste and it helped massively! Her breath doesn’t smell now! Xx
@Becca he seems ok within himself but I did notice a little bit of a runny nose tonight so maybe it could be a cold.
@Hazel what toothpaste have you changed to?
Mine has bad breath when he is teething...has yours got any left to come through?
Has he got a cold or seem under the weather? This happened to my daughter when she was poorly and turned out to be a really sore throat!
