White thing on tonsil part. Is it stone?

Hi dr I noticed this white thing above my tonsil in my mouth I can feel it with my tongue it's hard like food stuck I tried to remove with toothpick but not coming out Is it tonsil stones ? Or just debris caused due to unhygienic mouth or food particles ? It's there since many days so I don't think it's food It's been there for the longest time I visited an ent 3 weeks ago for acidity issues and he checked my mouth, I'm sure he must have noticed this as he checked me thoroughly he did not say anything What is this dr I'm scared Is it stone ? It doesn't cause me any trouble I do have mild cold almost always Is this a very insignificant finding. ? Am I worrying too much Pls reply respected dr I'm very scared Should I just leave it I think my ent did not find it important Pls guide me
