Strange Throat stuff

In the back of my mouth I can apply pressure just above my tongue and this white stuff comes out. What is this and should I be concerned?

You are likely retrieving something called a "tonsillolith".  Tonsil tissue is often what we call 'cryptic' and can easily accumulate this collection of dead skin, bacteria and food debris.  It generally looks whitish, with a cheesy consistency and smells like death.  Entirely benign, assuming this is what it is.

Hi there, I see you asked quite a long time ago now and your symptoms may have cleared up now, but you may be like me and they come and go many times through the year. I get them quite a lot, they are nicknamed tonsil stones and I find I get them more when Im stressed.
They are harmless but quite annoying and can leave a horrible taste in the back of your throat. They can be quite difficult to remove yourself if you have a sensitive gag reflex, but if youre like me then you'll have no trouble.
They are easy to remove with cotton wool buds, just shine a torch down your throat and apply pressure where you can see them and they just pop out with no pain. There are many holes in tonsils so can be tricky at times. Just make sure you brush your teeth really well and more importantly the back of your tongue. Because these "tonsil stones" are built up of bacteria. Hope I've helped. Zoe
