How long is a dental hygiene license valid upon renewal?

• A. One year.
• B. Two calendar years.
• C. Until next renewal.
• D. Three years.

Answer: (B)

Licenses for dental hygienists in Louisiana are issued on a biennial renewal cycle, meaning they are valid for two calendar years after renewal. When you renew, you’re granted a license that covers two calendar years before the next renewal is due. This two-year period is set by the Board to align licensure with continuing education and ongoing oversight. The other options don’t fit because annual renewals aren’t the standard, “until next renewal” isn’t a defined timeframe, and three years exceeds the established cycle. If you’re planning renewal, check the Board’s notice for the exact expiration date and any CE requirements.
