In general, it would be wise to plan on financing your cosmetic dentistry on your own or through one of the various financing plans offered by many dentists. While some dentistry is necessary, cosmetic dental procedures are often elected by the patient. Some dental offices offer short term, in-house financing for their patients. Third party financing sources are available with options such as no interest for 12 months and/or interest rates equivalent to purchasing a used car. Of course, one's credit history, and, if necessary, the availability of a co-signer affect the outcome of such financing options and the ability to qualify.
