The terms 'dentist' and 'dental surgeon' are often used interchangeably because most dentists perform dental procedures and are essentially surgeons.

You need to visit a dentist when you have a toothache, gum bleeding, sensitive teeth, yellowing teeth or cavities. In addition, it is a good idea to visit the dentist once every 6 months for a routine, preventive check-up.

A dentist may need to perform an X-ray in order to confirm their diagnosis before deciding on the treatment course.
