Were you informed that you have the same dental problem occurring on the other side of your upper jaw in your root canaled second pre molar? The rc filling material was pushed through the root of that tooth also. How long ago was that rc done? You also have an impacted wisdom tooth in that quadrant, similar to the one you recently had removed on the other side. In fact, the wisdom teeth are almost a mirror image of each other.

THE RIGHT SIDE UPPER TOOTH WITH ROOT CANAL BEEN DONE ABOUT 10 YEARS AGO, IT NEVER BOTHERED ME, SO I WAS NEVER CONCERNED ABOUT IT.
YES, I WILL BE EXTRACTING THE UPPER RIGHT WISDOM TOOTH AS WELL.

You have very large sinuses. Which could be normal for you and/or that could indicate generalized sinus inflammation. Do you a history of allergies, sinus congestion, post nasal drip, colds, or infections?

NO, I DONT HAVE A HISTORY OF ALLERGIES, SINUS CONGESTION, POST NASAL DRIP, COLDS, OR INFECTIONS. SO, THE FACIAL/SINUS PRESSURE, CLOGGED EAR IS DEFINITELY SOMETHING NEW TO ME, WHICH IS VERY UNCOMFORTABLE SINCE I HAD IT FOR ALMOST 4 MONTHS NOW.

Anytime you have a root canaled tooth, you will have inflammation, chronic bacteria within the dentin tubules of the tooth and some degree of ischemia in the surrounding areas, there are no exceptions to that. With upper teeth, and in your case having large sinuses, the roots of your posterior teeth are in very close proximity to the floor of your sinus. So any tooth problems in your upper arch are likely to cause symptoms in possibly the sinus, maxillary bone, palate, ears, etc.

It is never ideal to retain any amount of rc dental materials that were pushed up beyond the apex of the tooth during a root canal procedure. That material will be a constant irritant and source for bacterial growth.

SO, MY BEST OPTION WOULD BE TO CLEAN EVERYTHING OUT, RIGHT?

The previous dental ct scan, if it included the right side of your head can help determine the location of the rc material pushed through that present rc tooth. Your dentist may try to convince you to have an apicoectomy surgery to remove that material while leaving the tooth in your head. That surgery may or may not remove all of the material as visual access will be difficult. However, that surgery will likely increase the inflammation associated with the rc tooth itself and ultimately the tooth will need to be extracted. Ideally, if you extract that tooth, the surgeon can use that access wound to remove the remnants of rc material.

THE REASON I DECIDED TO EXTRACT TOOTH #15 WAS BECAUSE I WAS TOLD THAT THE ONLY WAY TO CLEAN OUT THE OVERFILLED MATERIAL WAS TO REMOVE THE TOOTH OUT AND CLEAN EVERYTHING OUT WITH IT. HOWEVER, I AM NOT SURE WHY THE SURGENT WASNT ABLE TO REMOVE ALL OF IT. IF WE LOOK AT THE PRE AND POST XTRAYS WE CAN SEE THAT THE MATERIAL HAS SHIFTED A LITTLE, SO I AM WONDERING IF MAYBE THE SURGENT WOULD TAKE MORE TIME TO TRY TO CLEAN IT OUT MAYBE HE COULD OF REACH FOR IT?

A new panoramic xray may be diagnostic enough or a dental ct scan of your entire upper arch would show the location of the rc material in the left side (post extraction) and the rc material in the right side above that rc tooth. So the oral surgeon wouldn't be guessing where it is.

SO THE CT SCAN CAN ACTUALLY SHOW THE EXACT LOCATION OF LEFT MATERIAL?
WE DID DO A CT BEFORE THE EXTRACTION AND THE SURGENT STILL WASNT SURE HOW FAR UP WAS THE MATERIAL

The burning sensation crossing over your palate from your left to your right could be what is called referred pain. This is when the bundles of irritated nerves communicate with each other. In your case, you have 2 areas of nerve irritation, one on each side of your mouth.

EVEN IF THE RIGHT ROOT CANALED TOOTH DOESNT BOTHER ME?

Regarding the ER visit with your breathing episode.... could be GERD but could also be anxiety induced GERD or a vagus nerve reaction to stress induced anxiety.

I hope your oral surgeon is willing to discuss this with you thoroughly enough to help you make an informed decision.

THANK YOU!!
