Welcome to HCM,
You are having severe gum disease
and this is very common problem and awareness about teeth and gums is very less, please understand clove oil is no treatment for Pyrrhoea.
You have to visit a Dentist
and if required a Periodontist.
Get examined by a good Dentist and if required get your full mouth Xray known as OPG
(Orthopantogram). Once abnormality is confirmed and if you have any diseased teeth they will require treatment like RCT or extraction depending on condition.
If you have mild gum disease a proper ultrsonic scaling would help to some extent if it is severe then a flap gum surgery would be required by a Periodontist.
If you have any deficiencies he/she will prescribe you medication then condition of your gum may improve.
Even after all treatment you will have to take care of teeth with proper brushing and mouth wash and dental flossing .
