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

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

Ear canal swelling due to sinus infection. How do I get it to go down?

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
