There are a few things you can do to help keep your teeth clean and healthy, without having to use floss. First, make sure you are using a toothbrush that is specifically designed for cleaning between teeth. This will help remove plaque and bacteria from your teeth more effectively. Second, use a mouthwash every day to clean away any built-up plaque and bacteria. Finally, brush your teeth regularly with a soft bristled toothbrush to remove any food particles that may have built up on the bristles.
