I HAD TOOTH #18 EXTRACTED 3 WEEKS AGO AND NOW

I HAD TOOTH #18 EXTRACTED 3 WEEKS AGO AND NOW I HAVE A LARGE BONE SPUR ON THE LINGUAL SIDE OF MY GUM. IT SEEMS TO BE GETTING BIGGER AND IT HURTS. WHAT ARE TREATMENT OPTIONS?
I HAVE ALREADY HAD IT GRINDED DOWN ONCE AND NOW IT IS HAVING SMALL SPLINTERS AGAIN FROM AREA. MY ORAL SURGEON SAYS WE ARE NOW "PICKING BONE". ITS A VICIOUS CYCLE. WHY CANT HE JUST GO IN AND CUT ALL THE BONE AWAY AND PULL THE GUM OVER IT?
