Whitby Dentist. At the Thickson Square Dental Office in Whitby, Ontario, we offer a vast variety of dental services and procedures. We offer family and cosmetic dentistry. We also offer endodontics (root canals), oral surgery (extractions), tooth bleaching and crown and bridge and veneers. Your smile and appearance are important to us, and we will try to help you get the smile which you wish to have. We use composite resins (white fillings) almost exclusively so that no one is aware that you have had fillings. more... See more text
