Will peridex do anything for tonsil stones?

Hi Handhurts2801,
Peridex is an antiseptic, so it may help with the odor, as kaismama has indicated.
But, it sounds as if you need an Antibiotic!
My daughter suffered many strep throats and ultimately ended up not telling me she had a sore throat, so she developed Scarlet Fever, with those funky little "squishy stones" on her tonsils, with breath that could wake the dead!
(Poor baby, she was too terrified of the doctor!)

Get thyself to a doctor asap, even if you've got to go to Urgent Care! You don't want this to end up being an out of control infection. Or, have you been to your doctor? If you have, what were you prescribed?

Best wishes and a speedy recovery to you,
Lara

It might do something for your breath short term. I'd be seeing an ENT dr and getting them removed.
