Dental procedures must respect esthetics, phonetics, masticatory and deglutition functions, oral functions and the neuromuscular system. The purpose of the present study is to make a literature review of the most important aspects of speech related to dental prostheses. Furthermore, propose a speech conference list to be used during dental treatment. Speech rehabilitation can be done by the reshape of teeth and palate of the dental prosthesis, reestablishment of the vertical dimension, of the free functional space and closest speaking space. For dental procedures, during the adjustment of prostheses, the most important sound is /s/. The correct production of speech might be altered when there is anterior open bite, teeth in bad position, teeth loss, inadequate shape and anatomy of teeth, alteration in vertical dimension, in free functional space and closest speaking space, discrepancy between overjet and overbite. The two most common speech errors are lisping and whistling. They are characterized as escape of air with substitution of certain sounds and whistle, respectively. All dentists must be aware not to install a new dental prosthesis with new speech sensations or alterations. To the correct production of sound, it is compulsory that all speech articulators and the stomatognathic system are well-balanced.
