Dental insurance providers attempt to reduce their costs by applying certain restrictions to your insurance policy.
The most common clause used by dental insurance companies to allow them refuse to pay for expensive treatment that you may need,
is a term called “least expensive alternative treatment” (LEAT), also known as the least expensive professionally acceptable treatment clause.

Under a LEAT clause, when there are multiple viable options of treatment available for a specific condition,
the insurance plan will only pay for the least expensive treatment alternative.
The diagnosis, evaluation and recommendation of the treating dentist must be evaluated by the insurance company before starting the treatment.
