There are times when dental care cost is too high or you feel as if maybe what your dentist is suggesting may not be necessarily. During those times, it is okay to get a second dental opinion. Specially if you do not feel that the treatment plan suggest to you is necessary right.
If you have dental insurance depending on the plan you may have to change providers for a second option, if your plan is a provider only plan. Otherwise if you have a plan that lets you go to your own dentist or different dentist going to another provider for a second opinion is not an issue.
