Hello and welcome to hcm,
From the details provided,its not clear that what was your concern for dental surgesy.
Since there is terrible odour,chance of sinus infection is high.
Take complete course of antibiotics.
Maintain good oral hygiene.
Smell will gradually subside once the infection relieves.
Also consult a physician regarding the stomach-ache.
Get your entire mouth examined and get all your decayed teeth restored and scaling done.
Grossly decayed teeth has to be removed.
Also check whether wisdom tooth is impacted ,and if impacted either operculectomy/extraction of tooth has to be done.

Dear friend.

Thanks for sharing your concern.

Halitosis or bad o dour in your mouth is due to two reasons,one is that your maxillary sinus is infected and not well treated,secondly poor oral hygiene.

please speak to your dentist regarding this and use antiseptic rinses locally to prevent lodgement of any food particles or bacteria.

you can get rid of this symptom only after infection is completely cured.

Hope it helps

Take care.

Thanks.

Hi,

Thanks for asking the query,

Halitosis in mouth can be due to poor oral hygiene that is plague and calculus deposition, can be due to sinus infection.

Stomach upset can be due to antibiotics prescribed to you, or there are chances drainage of abscess in the oral cavity.

Smell will subside after the infection subsides.
Get complete mouth scaling and polishing done.
Also consult to an Gasteroenterologist to look for any GIT disturbances.

Maintain a good oral hygiene.
Use chlorhexidine mouthwash gargles twice daily.

Hope this helps out.

Regards..

hello there ,

Bad or fowl mouth odor is caused by number of reasons such as;

Poor oral hygiene , improper brushing techinques which lead to accumulation of food debris and bacterial plaque and calculus deposits deep in the gum pockets and root surfaces of the teeth .
bacterial plaque and calculus on the teeth gives fowl odor.

Gingivitis and periodontitis is another condition which leads to fowl mouth odor.

Ulceration when infected with bacterial or viral invasion may lead to fowl smell.

sinus infection ,postnasal drip , periodontal abscess draining in the oral cavity leads to oral malodour. stomach reflux , GERD and other gastric problems may also lead to acidic mouth odor.

you need to consult a physician to get the problem confirmed.

i hope this helps ,

take care.
