While there is not one standard rate of pay for any particular job, the field of dentistry is a generally stable and lucrative field of work to go into. Most dentists get paid from 70,000 to 130,000 a year with those working in clinics making towards the lower end and those who own and operate their own private practices earning at the higher. Dentists who are also oral surgeons and so able to perform minor surgeries can also earn more.
