My holes closed over in a week?

How fast can they close?? Obviously I know deep healing is from within and it’s not actually healed but like…I started with blood clots Monday and it’s Friday now and my holes are completely covered by pink and healthy gum tissue. The bottom 2 are covered and the upper 2 still has stitches but also looks good. I don’t even have anything to irrigate anymore. Still won’t try eating a burger until maybe next week but yea, I think this was really quick??
