Foods with fiber such as vegetables and fruits help with saliva flowing. Calcium in dairy products and cheese help to remineralize teeth that might have lost due to acids. Green and black teas contain polyphenols that can interact with plaque bacteria from growing or producing acids that destroys teeth. Chewing sugarless gums increases saliva production and removes food particles from your mouth.
Bleeding gums can be caused by many different reasons, but mostly due to plaque accumulation. Plaque contains germs which attack the healthy tissues around the teeth. This will cause the gums to become inflamed and irritated, which may cause them to bleed when brushing or flossing. This is called Gingivitis and is the initial stage of gum disease or periodontitis. You should continue to brush properly for 2 minutes at least 2 times a day with a soft bristled toothbrush. Brush around the gum area gently. You will continue to have gingival bleeding when brushing or flossing, until your gums become healthier. Make an appointment with your dentist and have him/her check your gums and your teeth. Take care.
