Hutchinson's incisors are caused by congenital syphilis. Congenital syphilis is seen in babies born to mothers with syphilis, a sexually transmitted infection. Babies with this condition have teeth that are smaller and more widely spaced than normal, with notches in the middle. Hutchinson's incisors are one part of Hutchinson’s triad, or three symptoms of congenital syphilis, which includes keratitis (inflammation and redness of the cornea or front part of the eye) and deafness in addition to Hutchinson's incisors. Treatment typically focuses on treating the child’s syphilis, and some patients choose to have their teeth straightened so that they are more aesthetically pleasing.
