Pain in jaw and mouth after implant removal and bone graft

Mostly likely it is a post-op infection you have acquired. A very thin chance of allergy to graft material which was suppressed due to medication post surgery and might have flared up once the course was over. Please see your dentist at the earliest.

your statement indicating chances of infection. so its my advice to visit your dentist as soon as possible.

Hello,This doesn't sound normal. Healing time is usually one week. Your symptoms should improve with time not worsen. It sounds like you have developed a post op infection.  The grafting procedure might be compromised.  Have your surgeon reevaluate the site as soon as possible. If the graft is compromised:It will need to be removed,\The  assumed infection can lead to pain at the site of the surgeryPain can radiate to the jaw on the same side of the surgery  The white tissue can be attributed to clotting or indicative of poor healing (infection). If the graft is not compromised:You many need a different antibiotic.Follow up appointment to re-evaluation the surgical site to rule the other potential issues.Hope this is helpful. Best Regards,  

Thin my experience it seems as though you could have an infection. Bone grafts are tricky and if the gum opened up even a little bit around the graft, you could be experiencing complications. See your surgeon 

This is unusual.  Implant removal is very similar to tooth removal in the symptoms experienced after the surgery.  Symptoms typically present for 2-5 days.  To have pain a month later is very unusual.  You should go back to your doctor to evaluate.  This can be infection of the graft, infection of the bone, trauma from something or something else.  The earlier you go it to figure this out the better.
