Dental Assistant Salary in Tennessee 2026,
$46,720 Median | BLS Data by City

A median $46,720 a year, or $22.46 an hour, per BLS OEWS May 2025 — only 2.8% below the national median of $48,070. The middle half falls between $44,440 and $59,270 and the full band runs $37,810 to $61,260. Because Tennessee levies no state income tax on earned income, the take-home position is better than the gross comparison suggests.

Nashville-Davidson–Murfreesboro–Franklin at $48,540, marginally ahead of Memphis $48,200, Knoxville $46,790, Jackson $46,590 and Chattanooga $46,360. About twenty-two hundred dollars separates the whole table, so every major Tennessee market pays close to the state figure and choosing between them is a matter of housing costs and preference rather than pay.

Yes. The Tennessee Board of Dentistry registers dental assistants and separately requires dental x-ray certification before an assistant may take radiographs. That gives Tennessee a stronger and more portable credential structure than most southern states, where the role is either unregulated or governed only by what an individual dentist chooses to delegate. The board also sets which functions a dentist may delegate to a registered assistant.

No. Tennessee levies no state income tax on earned income, and the Hall tax on investment income was fully repealed in 2021. At the $46,720 median that is worth more than two thousand dollars a year compared with a state charging five per cent, and it applies to overtime and extra hours too. The trade-off is that Tennessee funds itself through a high combined sales tax, which falls hardest on households spending most of what they earn.

Because the 25th percentile at $44,440 and the median at $46,720 are close together while the 75th jumps to $59,270. That gap of nearly thirteen thousand dollars between the median and the 75th percentile is where specialty practice, lead assistant responsibility and coordination roles sit. In other words, most Tennessee dental assistants are clustered around a fairly narrow general-practice rate, and the earning opportunity is concentrated in a distinctly separate upper group.

It makes the qualification portable and verifiable, which sounds administrative but has a real wage effect. In states where dental assisting is unregulated, an assistant's value to a new employer rests on references and a trial period; in Tennessee, board registration plus x-ray certification is a documented baseline any practice can confirm, and the board's rules define what a dentist may delegate to a registered assistant. That is part of why Tennessee's 25th percentile of $44,440 sits so much higher than the unregistered floor in neighbouring states — the credential establishes a rate below which registered assistants generally do not go.

It blends part-time with full-time work, common in dental practice, so the $22.46 hourly median is the cleaner benchmark. The five published metros cover Tennessee's main markets well but leave rural East and West Tennessee practices outside the table. And a location quotient of 0.91 means the state employs the role slightly below the national rate, so the supply of posts is not quite as deep as the population would suggest.

Board registration and x-ray certification first, because they are the state's baseline and the step from the $37,810 tenth percentile to the $44,440 twenty-fifth is over six thousand dollars. Expanded functions second, governed by what the Board of Dentistry permits a dentist to delegate. Specialty practice third — oral surgery and orthodontics occupy the upper band, and the jump from the median to the $59,270 seventy-fifth percentile is where they sit. Lead assistant and practice coordination fourth, reaching the $61,260 ninetieth percentile. Geography contributes very little in this state, which is unusual and useful.
