hello and welcome
as per the details provided,the origin of discharge of saliva has to be ruled out.

this can be a sinus infection too.

a thorough clinical as well as radiological examination is mandatory for diagnosing the source of infection.

sialography,radiological examination of teeth as well as hard palate has to be ruled out.
cosistency of saliva has to be checked.

I would suggest you to visit a dentist and get thorough clinical examination.
deep scaling and restoration of teeth has to be done.
take care.

Maxillary sinus may be accidentally opened during tooth extraction/dental work and can lead to bitter taste in mouth and leakage in mouth. Roots of upper teeth are close to the sinus and mouth sinus communication could have occurred during tooth extraction. This complication is more common when teeth project into sinus when there is considerable bone present between floor of sinus and root apices. In most cases, opening which occurs is small and blood clot filling the extraction socket will close the openings unless the sinus is infected. If opening is of considerable size, then sutures are placed across the socket to approximate gingival tissues. Some absorbable material may also be used. Large openings can be closed with buccal flap. You can visit an oral surgeon for evaluation and treatment.

Hi,

Thanks for asking the query,

This can be due to dental infection or infection of nasal or paranasal sinuses.
I would advice to undergo complete dental examination.
Get an x-ray done .

It would be better if you get mucus culture done.

You can also get an allergy testing done & CT Scan.

hope this help out,
Regards.

Hello,
Thanks for posting your query,
You might be suffering from sinus infection.
visit the dentist and get it evaluated
you have to get some radiological examination for better diagnosis and treatment plan according to that.
oral prophylaxis is mandatory and get all your tooth checked and maintain in good health
Spicy foods that contain hot peppers may help clear sinuses
Inhaling steam 2 - 4 times a day is extremely helpful, costs nothing, and requires no expensive equipment
I hope this information has been both informative and helpful
Regards

Hello,
I am Dr.Neha Gupta (dentist) and am glad to address to your query here.
you might be having infection in sinus.
Sinusitis is inflammation (swelling) of the lining of the sinuses, caused by a viral or bacterial infection.
A thin, flexible tube (endoscope) with a fiber-optic light inserted through your nose allows your doctor to visually inspect the inside of your sinuses.
get plenty of rest
drink plenty of fluids
apply warm compress
sleep with your elevated head
