<bot>: Hi, Thanks for asking the query, Sour taste in the saliva can be due to abscess formation it can be because of many reasons , gingivitis inflammation of the gingival due to plague and calculus deposition, Periodontal abscesses formed due to decayed tooth, Depositions on the tongue due to poor oral hygiene . Visit to the Dentist and get checkup done . Get complete mouth scaling polishing and root planing done. Maintain a good oral hygiene , use lukewarm saline gargles 3-4 times a day , use antiseptic mouthwash gargles twice daily . Avoid eating hot and spicy foods. Take vitamin supplements. Hope this helps out. Regards.
