Hello there ,
Thanks for writing your query,
According to your clinical history i suspect your wisdom tooth is in close proximity to the vital structures in the jaw like the mandibibular .
In such cases , extraction of the wisdome tooth is avoided as it my lead to damage to the nerve and permanent numbness.
infection in the tooth has gone worse and you have developed a periodontal abscess
due to spread of infection to the underlying tissues.
This type of periodontal abscess drains in the oral cavity and may lead to nausea and vomiting
This type of periodontal abscess needs to be drained and compressed in position and then followed by a course of antibiotic and analgesic
will subside the symptoms of pain and swelling.
once the abscess is drained the infected tooth needs to be explored for root canal
you need to get an x ray done the affected area to confirm the presence of infection, approach a dentist
for the treatment.
i hope this helps ,
