A Dental Corporation’s Bylaws are the rules under which a corporation can operate.  They dictate the corporation’s internal business and layout rules and procedures for all of its affairs. The board of directors or shareholders may add, remove, or change provisions of the bylaws upon a satisfactory vote. Unless there are less than three shareholders, a Dental Corporation Bylaws must have at least three directors. It is very common for dental corporations in California to have only a single shareholder, in which case they are only required to have one director.
