Flossing is very important and should be done at least once a day. Use a threader to pull the floss under your archwire. Pull the floss between each tooth moving it up and down gently all the way under the gums. Use a different section of floss between each tooth.
An interdental toothbrush is a great tool for keeping your teeth, braces, and gums clean and healthy. It can be used under wires and around braces. Be slow and careful in order to not damage your braces.
It is very important to brush your retainer every time you use it, as it can accumulate food particles and cavity-causing plaque. Additionally, you should soak your retainer in a cup of room-temperature water with a denture-cleaning tablet every day to prevent plaque build up and oral infections. It will also keep your retainer clean and tasting better. Never use hot water with your retainer as it can distort the shape.
Hard Foods, like ice or pizza crust
Sticky Foods, like chewing gum, caramel, starburst
Sweets, like hard candies, now and later, and high sugary foods
Sugary Drinks, sodas and fruit drinks sweetened with sugar
It is best to avoid these foods that can damage the wires and braces and avoid those foods that are more prone to cause white spots due to high sugar content.
