During the Thanksgiving holiday, you are probably going to consume more foods that contain carbohydrates such as sugar and flour. The food particles from cookies, candy and cake will stick to your dental enamel, leading to a build-up of plaque. Scheduling an appointment at your local dentist office for a teeth cleaning after the Thanksgiving holiday is a great way to prevent cavities. There are also other excellent ways to protect your teeth throughout the Thanksgiving holiday to avoid developing dental decay.
