Use Brushing Toothpaste - If your teeth aren't clean enough and your gums continue to be infected, your dentist may recommend brushing and flossing with specially formulated toothpaste. These types of products are designed especially to fortify your tooth enamel. The toothpaste works by coating the top of your tooth and drawing from the bacteria that causes plaque. It's special enzymes which attack the bacteria. This type of toothpaste works great if you brush your teeth regularly, particularly before bed time or when you first get up in the morning.
