Green Tea

3) Green Tea Natural Cure for Gingivitis
My drinking green tea has proven to be a great home remedy for gingivitis.  It is only a matter of minutes after I’ve had some green tea that the pain, discomfort, and swelling dies down.
 
I have found that bicarbonate of soda (baking soda) is a great home remedy for my gingivitis.  It really helps to treat my gums when they swell up and bleed.  Usually within 30 minutes of having my bicarb treatment, and the pain and swelling will be gone.
 
I have some good advice to help you with gums that are swollen and painful.  Get some hydrogen peroxide and add it to some water and rinse with it several times thorough out the day.  You’ll soon see some good results.

4) Diet as Natural Remedy for Gingivitis
A good home remedy for treating gingivitis should be focused on your diet.  If your diet is rich in vitamin C you’ll help yourself combat gingivitis.  Your overall diet should be low in saturated fats and have lots of fresh fruits, and vegetables.  Also you need to have enough fiber in your diet.  The less you have vitamin C in your diet and the more is an increased risk of developing gingivitis.  Often times, people will need to take a vitamin C supplement in effort to help restore the health of their gums.  You should always try to eat foods that are rich in vitamin C.  You should avoid white flour, white rice, syrups, and drinks with sugar of fruit juices.

5) Salt as Gingivitis Natural Cure
I have a home remedy I use for gingivitis when I start to experience swelling in my mouth.  I gargle a couple times a day with my own saline solution that I make containing warm water mixed with a little salt.  This always seems to take away the swelling and pain.
