The odour coming from mouth 1 week after surgery is due to slough filling the adenoid
region..it will go away,dont worry.But fever everyday since then means his antibiotic needs to be changed to something more than amoxycillin
.He may take Betadine
mouth gargles after each feed,oral hygiene
is very important.That will reduce the foul smell.You may consult your ENT Surgeo for the change of antibiotic.
