Why was this tooth root canaled in the first place? Did it have a large cavity or did it break? How many times was it root canaled and was there any other treatment done on this tooth like an apicoectomy?

So all of these years and noone ever mentioned that white material seen on the x-rays? If the previous dentist did not have digital at the time the pre op xray was taken, then tell him you want him to make a copy of the xray that he has to keep in his records and you want the original. They legally have to oblige your request. The reason you want the original is because a copy may not be very diagnostic. Also, if an endodontist did the root canal... he may have taken a pre op also and you can call him for that original or digital whichever he has.

Anytime you have an infected or root canaled tooth removed, you should always be given a post op appointment within 2 weeks of the extraction. That is just lame to tell you everything is fine and not to come back. :/

Unfortunately more times than not patients with root canaled teeth will have radiographic artifacts or pathology that goes undiagnosed.... never mind mentioned to the patient.... for years upon years. This is truly misleading the patient to believing that because the tooth is root canaled there cannot be a problem with it. I am sorry to tell you that you are a perfect example of that nonsense

This white area could be on the sinus scan as it is very close to the sinus if not in it. But it may not be standing out as anything significant. I think if the ENT was to see the dental xrays he may look twice at the scan and be able to pick it out. A dental CT scan may show this area more clearly but it might be on the sinus one and I would hate for you to have additional radiation for nothing.

I can confidently tell you this..... all root canaled teeth are inflamed and infected as those tiny accessory canals are jammed with necrotic nerve tissue rendering the tooth very unhealthy. So it is no surprise that you have had various physical symptoms over the years most likely associated with that sick tooth. Now the tooth is gone but the bone is still inflamed and it will be for awhile and the white material may be causing further irritation in an already irritated area.

Sometimes the body heals the inflamed area and the symptoms go away. Other times there is a constant irritant. There really is no way to know for certain how this will go.

Whether or not it is wise to go in and remove that material is a judgement call from the oral surgeon and the ENT. It would first be best to determine exactly where it is located so the path of entry is as non invasive as possible. It is up to the OS and the ENT as to what other scans or xrays may be helpful in doing that.
