Certain Medications and Mouthwashes
Many people don’t realize that certain medications and mouthwashes can cause yellow teeth. The side effects of certain drugs, such as antibiotics and heart medications, are some of the most common causes of yellowing teeth. The active ingredient in these drugs can deposit on your teeth and discolor them. If you take these medications, ask your dentist if they will cause discoloration or if you should use an alternative medication.
Side effects of certain mouthwashes may also lead to yellowing. For example, mouthwashes containing alcohol can dry out your mouth, making bacteria more likely to grow on your teeth. The bacteria produce a substance that is yellow in color and deposits onto the surface of the tooth, which causes discoloration.
