Hello,
Thanks for your query.
There are a number of simple dry mouth syndrome treatments that are designed to restore moisture to your mouth. Your dentist may recommend:

Sugar-free candy, sugar-free gum or gum specially made to stimulate saliva flow.
Specially formulated oral rinses.
Artificial saliva (saliva substitute).
More fluid intake (frequent sips of water, sucking ice chips).
Oral moisturizers (sprays or gels).
Oral prescription medications to induce saliva production.
I do hope that you have found something helpful and I will be glad to answer any further query.
Take care

Thanks for your query, I have gone through your query. The reduced salivary secreton can occur because of any obstruction in the salivary gland duct like stones or secondary to drugs like antihypertensives, antidiabetic, antiallergic etc. The cause has to be found out first.
the salty taste could be because of any pus discharge from gum infection or tooth infection. consult a oral physician and get yourself examined to rule out the above said conditions.
for the dry mouth you can take artificial salivary substitutes like wet mouth gel, sugar free candies,. Keep sipping water. For salty taste if any tooth or gum infection causing pus discharge has to be treated. you can use mouth wash.
i hope my answer will help you, take care.
