<s>[INST] Good afternoon,I have a cracked tooth (tooth before the wisdom tooth in the left side) and the area around the tooth is red and has a medium size white bump next to it that just appeared today (10/7/14). I have a dentist appointment on  Wednesday, October 15th, 2014. May I know more or less what this could be? any opinions, will be greatly appreciate it. [/INST] Thanks for your query, I have gone through your query. The white bump around the cracked tooth can be a periapical or periodontal abscess secondary to infection from a cracked tooth. If I am your treating doctor, I would suggest you to take a radiograph like IOP AR to confirm the diagnosis. If there is an infection in tooth, then get it treated with root canal treatment. I hope my answer will help you, take care. </s>
