HI ROCKYY,

Thanks for posting your query.

The foamy liquid is due to the abscess formed at the periapical area of involved tooth.
The pus usually contains bacteria.
I would suggest you get the tooth either root canal treated or extracted depending on the condition of tooth.
Take complte course of antibiotics too.
The sour taste will disappear once the pus drains out completely.
Maintain good oral hygiene.
Please get the treatment soon as it can lead into sinus infection if left untreated.
Hope this helps.

Hi,

Thanks for asking the query,

It can be due to abscess formation ,either a periodontal abscess arising from the infected tooth or gingival abscess due to accumulation of bacterial plague and calculus deep in the gum pockets.

Draining of this abscess and pus in the oral cavity leads to nausea , vomitting , halitosis and stomach infection.

I would suggest you to go for complete clinical examination, get an x-ray done.
Drainage of the abscess is required.
Get complete mouth scaling and polishing done.
Take complete course of antibiotics and analgesic.
Use saline water gargles 3-4 times a day .
Maintain a good oral hygiene.

Hope this helps out.

Regards....

hello there ,

Infected or decayed teeth may spread infection to the underlying structures through the root apex leading to periapical infection and abscess formation.

Putrid drainage you can see is the periodontal abscess draining from the infected tooth.

i suggest you to get and X ray examination done for your teeth which will show the amount of damage and the teeth involved accordingly treatment can be done.

periodontal or periapical abscess needs to be drained followed by root canal treatment of the affected tooth and a course of antibiotic and analgesic will cure the problem.

i hope this helps ,

take care.
