Hi! Welcome to Healthcaremagic.
I read your query. Is this pus in only limited part of gums as you mentioned or is it generalised? Do you notice any cavity in tooth near pus area?
If there is, this pus can be due to dental infection, for which you need to visit a
dentist.
If there is no cavity, then this pus can be due to
gum disease. Is the tooth in that area mobile, calculus deposit or gum receding?
You need to visit a dentist. Get an x-ray done if required. In case of gum disease, you will be given an antibiotic course. If there is not much bone loss and tooth firm, scaling and curettage will help in removing infection.
Maintain good
oral hygiene. Do warm saline rinses. Use
chlorhexidine mouthwash twice a day.
Massage gums using gum paint. Take healthy diet and multivitamins. Have regular oral prophylaxis. This require good and sustained oral care.
Hope the answer helps you. Thank you.
