Does every closing California dental office have the same record-retention period?

No general California law sets one retention period for every dentist. The familiar adult and minor periods in HSC §123145 apply only when a provider licensed under one of four listed HSC provisions ceases operation.

Direct answer

Do not treat seven years as a universal private-dental-office rule; the Dental Board has said no general law sets one period for all dentists.
For providers licensed under HSC §§1205, 1253, 1575, or 1726 that cease operation, adult records must be preserved at least 7 years after discharge and unemancipated-minor records at least 1 year past age 18 and never less than 7 years after discharge.
Medi-Cal, payer, contract, litigation-hold, and professional-liability requirements must be analyzed separately.

Common trap

Do not turn HSC §123145's narrow facility-closure rule into a universal seven-year floor for every dentist.
