Patient mobility is increasing. 'Dental tourism' is driven by numerous factors. These factors include the high cost of local care, delays in obtaining access to local dentists, competent care at many international clinics, inexpensive air travel, and the Internet's capacity to link 'customers' to 'sellers' of health-related services. Though dental tourism will benefi t some patients, increased patient mobility comes with numerous risks. Lack of access to affordable and timely local care plays a significant role in prompting patients to cross borders and receive dental care outside their local communities.
