An intraoral camera is a camera which is designed to be used in the mouth for the purpose of taking video or still photography. These cameras are most commonly used in dental offices, although patients can also use them at home to monitor dental health or to satisfy curiosity about what the inside of the mouth looks like.

The intraoral cameras designed for use in dental facilities come with disposable probes or probe covers to ensure that germs are not passed between patients, and they may come with a variety of options which enhance the functionality of the camera. Versions designed for home use are usually much more basic, but they can still be useful for people who want to see the inside of the mouth.

The intraoral camera is very small and approximately the size of a pen. Because of its small size, the camera can reveal images of the teeth from angles previously unseen. All exams using the intraoral camera are completely sanitary, as a different disposable camera cover is used on each patient every time.

The intraoral camera is not just a diagnostic tool, but it also serves as an educational one too. In the past, dentists have struggled to explain dental decay and other health problems to patients. Most people cannot see well into their own mouths, which leaves dentists to drawing diagrams or using props to attempt to explain what is going on in the mouth of their patients.

With the intraoral camera, however, the patient sees exactly what the dentist sees on an in-office screen. If necessary, the dentist can pause on a particular tooth or area of the mouth to point out problems and explain possible treatment options. This also frees the patient to ask questions and become a part of the examination process. When dentists can point out specific places on the actual teeth that are decaying, patients may have a better idea of how home hygiene practices and brushing techniques are affecting them.

Images taken by an intraoral camera can also be reviewed later, which can be useful for a dentist who feels a nagging suspicion that something is not quite right in the mouth of a patient. The intraoral camera can also be used to document procedures for legal and educational reasons, and to create projections of a patient's mouth which can be used in medical schools for the purpose of educating future dentists about various issues which pertain to oral health.
