Can a dentist prescribe controlled substance to spouse if they are patient of record?

In the United States, dentists are not authorized to prescribe controlled substances to their spouses or any other family members. This is because prescribing controlled substances requires a valid Drug Enforcement Administration (DEA) registration, and dentists are not eligible to obtain a DEA registration.

Additionally, dentists are prohibited from prescribing controlled substances to themselves. This is to prevent dentists from abusing their prescribing privileges and becoming addicted to controlled substances.
