Is gingivitis curable? if so, what are some home remedies?

It is curable..: But you really need to be evaluated by a dentist. You've diagnosed yourself and you may have a bigger problem than you realize.

Yes, see below:: First and foremost one needs to practice good oral hygiene, brushing teeth and gums with a soft brush and flossing. I strongly advise using a WaterPik or (even better) Hydrofloss to clean particles out of tiny pockets at base of teeth. Healthy diet (avoid sugar). Quality multivitamin and CoQ10. I like Oral Health tincture from HerbPharm, swish in mouth AM and PM. See http://tinyurl.com/he532py

Good oral hygiene: Dentist should differentiate between gingivitis and periodontitis. Have a professional cleaning to start, then brush & floss as instructed by your Dentist for best results.

Proper home care: Gingivitis is the inflammation and swelling of the gums preceding any permanent bone loss. If gingivitis is not treated it can lead to periodontal disease which is when bone loss starts to happen. Regular 6 month cleanings at the dentist and proper home care of brushing and flossing should reverse gingivitis. This can be determined by your dentist.
