Dr. Anagha Joshi has employed advanced technology and continuing education to stay up-to-date on all aspects of masticator maintenance for nine years. During the approximately hour-long visitation, Dr. Joshi ventures into facial caverns in search of cavities, gum disease, and ingrown milk moustaches. Then, low-radiation digital x-rays expose hidden oral underworlds, uncovering subsurface cavities and other problems between tooth, gum, and bone. Unlike many artistic dentists, Dr. Joshi resists the urge to spoil spotless tooth canvases with freestyle toothpaste doodles, and instead unleashes her creative impulses in a stunning series of oil paintings.
