Thanks for your query, I have gone through your query. The gingivitis is because of the gum infection secondary to the deposits. Consult a oral physician and get your teeth cleaned once and maintain oral hygiene after that. The other possible cause of the gingivitis could be open bit or mouth breathing. If it is because of open bite then the occlusion of teeth has to be corrected. Mouth wash will maintain the oral hygiene, you can continue to use mouth wash, But cause has to be removed. The peeling of the gum has started after taking that tooth paste, then you have to stop that tooth paste and use some other tooth paste. I hope my answer will help you, take care.
