Thanks for your query, I have gone through your query. pregnancy gingivitis is common during pregnancy, nothing to worry, its because of the hormonal changes. Once you deliver everything will be fine. Right now nothing to be panic, just maintain the oral hygiene by brushing morning and night. Rinse your mouth thoroughly after eating anything. Do not use chlorhexidine mouth wash, instead you can rinse with warm water with little salt dissolved(saline) in it. Once you get time you can get your teeth cleaned. you will not loose any teeth just because of pregnancy gingivitis. I hope my answer will help you, take care.
