A white clot is not what I would call normal. You may have an infection, and what you are seeing is a pus pocket. Call your dentist. He/she can call in an antibiotic for you to your pharmacy.
I have a white slime covering the white clot where teeth were pulled. The slime comes off after rinsing but white clot still there. Is this normal?
It is probably dead tissue, when you have a tooth pulled the site swells, as it heals dead tissue can come off. Just make sure not to dislodge the clot.
