Hi vRap,

The pocket behind the second molar was actually caused the wisdom tooth sitting so close to that molar. The wisdom tooth caused the bone to deteriorate in between the two teeth resulting in a deep pocket. If you had not removed that wisdom tooth the bone deterioration would have occured anyway and a cavity would have eventually formed on that second molar from food debris getting stuck in there. A cavity can still form in that area if that pocket continues to have food debris trapped in it. What usually works to prevent that from happening at this point is gentle but thorough toothbrushing and flossing in that area. Also, rinsing with xylitol after you brush at night will also help to keep the bacteria down. If the pocket is clean and food does not get trapped for more than a day, the pocket may shrink and tighten up. Keep in mind that plaque is bacteria and anytime it accumulates anyplace on your teeth.......there will be problems.

With regard to the exposed bone........this may or may not heal on it's own. It is something that has to be monitored at your regular checkups and with periodic xrays. If you develop any pain or achiness in that area.... even many months down the road, do not wait to see your dentist.
