Glossary Q&A
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.
