What to do about chronic sinus infections after root canal/crown. Dentist is dismissive of the problem. 2 years ago i cracked a tooth because of a deep cavity i was unaware of (that parts my responsibility) the tooth was also infected. I had a root canal

I : I would recommend getting an evaluation by a board certified oral and maxillofacial surgeon. Their training would enable them to determine if the 2 year history of sinus infections is directly related to your dental health. Obviously I am not in a position to examine you or review xrays of the teeth and sinuses, but 2 years seems a long time to have chronic sinus infections without significant oral findings other than decay. It is normal for the root tips of the upper back teeth to be close to the sinus, in fact, in many cases the roots actually protrude into the sinus. That is why these teeth can sometimes be symptomatic with sinusitis. The oms can give you an opinion as to whether the tooth should be removed or it there are other options for treatment. ...Read more

I've had a recurring sinus infection, coupled with severe tooth pain. Do i possibly need a root canal?

Maybe...: It sounds like there is an infection that is tooth related. If this is the case and your tooth can be saved, a root canal may be your answer. There are too many issues to resolve without a professional evaluation. See your dentist asap and get well ;-). ...Read more

I have symptoms of sinusitis with mild facial swelling. A year ago, I had a root canal on the same side on the upper molar number two with a crown placed. That tooth is tender now. What could be the cause of swelling, tooth or sinus? I am not sure whom to

Dentist First: From you history, i would start with the root canal tooth, then work from there. It is possible, given your timeline, that the root canal possibly failed, and the infection recurred. If so, treatment is necessary and may allow you to still save the tooth. It is possible it's a sinus infection, but my first guess would be the rct tooth. You want a "pa x-ray", digital if possible, or ct scan. ...Read more

What are possible complications of a chronic infection in the sinus because of a perforation from a root canal?

What are possible complications of a chronic infection in the sinus because of a perforation from a root canal?

See Endodontist : It depends upon what was placed into your sinus. If it was the disinfecting solution the denist uses to clean your canals then the sinus usually recovers with no intervention. However, if the 'filling material' of the root canal was placed in the sinus then you need the help of an oral surgeon or ent. Since you said this is 'chronic' i would suggest getting this looked at soon. ...Read more

Ent and no sinus issues been to dentist and had a old root canal removed and had some infection been on penicillin  when i eat chruncy my ear plugs?

Ear problema: It's not a specific symptom to get plugged ears when eating crunchy. If, otherwise, you are doing well, i would not worry, just wait until you heal up and see how you feel then. If you have other symptoms - nasal congestion, drainage, facial pain, then you will need to address sinus issues and hopefully the ears will unplug once the sinus issues resolve. ...Read more

Antibiotics: If you have a sinus infection and those symptoms then you would need an antibiotic, a steroid nasal spray, two days of a decongestant spray such as afrin. Mucinex (guaifenesin) is an option to thin the mucus and possibly a decongestant pill like sudafed depending on certain factors in your history such as you blood pressure and heart status. If this is repetitive then allergy skin tests are necessary. ...Read more

I was wondering is it ok to undergo root canal when I have slight fever, i also have sinusitis?

I was wondering is it ok to undergo root canal when I have slight fever, i also have sinusitis?

Depends: It depends on whether you can breathe through your nose, and how bad your fever is. Of course it also depends on how much pain you are in. If you are not in severe pain, you should wait until your fever is better. Your sinusitis may be cause by an upper tooth that needs root canal treatment (if your root canal treatment is to be performed on an upper tooth). ...Read more

How toothache can cause sinusitis , with knowing the tooth with root canal treatment (upper right first molar)?

Not unusual: The roots of the upper first molar are often very close in proximity to the maxillary sinus. A sinus infection can cause a toothache, and a tooth infection can cause sinus pain. Or the two can occur independently. This tooth is the most common one for a root canal to fail due to its complexity. Seek evaluation by an endodontist, preferably one with 3-d imaging (cbct). Usually treatable. ...Read more

It is better to get a tooth removed or another root canal. I have had three infections in this tooth,?

Poor prognosis: The damaging microbes from the dental infection grow in the mouth and then find their way by spreading to other organs of the body making you sick. The prognosis of this tooth is poor. The current research points to a higher predictability of success with the extraction and dental implant placement in this situation. See your dentist ASAP. ...Read more

Dr. John Yu Dr. Yu
1 doctor agreed:

Not really: Tooth infection is caused by micro-organisms. As long as your tooth is sealed off smoking will not affect the tooth. However, smoking does constrict your vessels and decrease the healing ability of your gum and bone around the tooth. Smoking is not good for your gum health. ...Read more
