There are some easy steps you can take to help make your teeth whiter by removing surface stains. Start by switching to a whitening toothbrush and toothpaste. There are also whitening mouthwashes that help to remove stains. For stains between teeth, flossing or using another type of interdental cleaning, such as dental picks, flossers, or interdental brushes, can help clean away stains. For stains below the surface of your teeth, consider using tooth whitening strips, or consulting with your dentist to weigh all of your options.
