Hello there ,
Thanks for writing your query,
Salty taste in the mouth is may be due to several reasons like underlying dental infections .
arising from infected teeth that may drain in the oral cavity leading to salty taste in mouth , nausea and vomiting.
which is caused due poor oral hygiene
,improper brushing and flossing that leads to accumulation of bacterial plaque and calculus deep in the gum pockets and root surfaces of the teeth.
Gingivitis presents with symptoms of redness , bleeding gums
, swelling , pain ,recession and sensitivity.
It needs to be treated by thorough professional deep scaling of gums and root planing of the teeth to remove all the irritants ,this will help in resolving the symptoms .
i would suggest you to go for symptomatic treatment at home like gargling with lukewarm saline water or antiseptic mouthwash like chlorhexidine
i would suggest you to get and OPG radiograph done which will help in diagnosis and accordingly treatment can be planned .
consult an oral surgeon and get the examination done
i hope this helps ,
