What are my gums so irritated?
First off, good for you for taking care of your teeth! I am sure you are doing your best. Puffiness in the gum tissue can be caused by plaque or hormonal changes. Since you have braces, plaque is very hard to remove 100%. Your gums become inflamed in response to the irritation from the plaque. If you make sure you remove 100% of the plaque with brushing and flossing your gums will heal. You might need to add a mouth wash to your routine also. Be sure you are seeing your general dentist for regular cleaning and check ups. Ask if they can give you some floss theaders.
