My dentist said a very sore spot in my mouth is probably a bone spicule. What now?

The dentist said to wait a month & if it's not better, to come back for possible referral to surgery or pathology. I can't find any helpful info online about bone spicules occurring in the mouth. I understand these are usually a spike of bone but I would like to know what the differential diagnoses are. I've been gargling with salt water & using a prescribed periodontal rinse & this evening there was less pain so I felt it & it definitely is not something soft like a pimple. I then managed to sc off a very tiny piece with my fingernail & it is definitely something very hard - like bone. Could someone please tell me what diseases a dentist or physician would suspect when a bone spicule appears or if this might just be something benign & what that might be. I have had no recent extractions in the area, but I did recently have gum surgery in an adjacent area. Thank you so much!
