Before your visit, you may want to avoid eating, don’t brush your teeth harshly, and don’t forget any oral appliances you use. Avoiding food isn’t entirely necessary, but it’s nice to keep in mind that we’ll be subject to any food smells that are left in your mouth. Brushing your teeth lightly isn’t a bad thing, but cleaning too much before your appointment can actually impair our ability to see which areas of your mouth may be more prone to plaque buildup.
