How much will it cost to get my teeth filed/shaped properly? & is it safe?

Safe: Absolutely. Safer than riding in a car. Safer than getting into a bathtub. As to cost, that varies according to your need and the restorative procedures done to resolve your specific problems. See a Dentist, have a cleaning, examination, x-ray's, and then the Dentist can discuss treatment options and costs with you. Seek quality care.

Cost unknown: Impossible to tell you what your treatment will cost. Safe? Of course.

Contact DDS: Need specifics to comment. Most dentists will advise a consultation to ascertain your individual needs, complete with radiographs. It is very rare that any dentist will quote fees over the phone, since you need to visualize to make a diagnosis.
