Hi,
Thanks for posting the query,
Gingivitis is a condition which includes infection and inflammation of the gums .
It also shows symptoms like
redness , bleeding gums , pain and sensitivity of the tooth.
You need to get a complete mouth scaling and polishing done .
Root canal of the tooth is required when it is infected and the infection had spread to the pulp and periapical tissues . Take a complete course of antibiotic and
analgesic .
Get the root canal completed.
It is good that you had done with your blood testing , wait for the results.
Bacterial and viral infection can lead to
abscess formation ,
fever and sore throat.
You can take tab paracetomol TDS along with antibiotics and analgesic.
Maintain a good oral hygiene , use antiseptic mouthwash , use lukewarm saline gargles.
Hope this helps out.
Regards......
