Cavities between front teeth
Cavities between front teeth are decay lesions on contacting enamel, often found by examination and bitewing imaging.
The short answer
Plaque bacteria use dietary sugars to make acids that dissolve enamel at the contact area between incisors or canines.
How can you clean and assess between front teeth?
Clean between teeth daily, use fluoride toothpaste, and arrange an examination to classify the lesion.
When should a dark mark between teeth be examined?
See a dentist for a dark mark, food trapping, sensitivity, pain, or a rough edge.
What should you ask about a cavity between teeth?
