Dental Hygienist Salary in South Carolina 2026,
$84,340 Median | BLS Data by City

A median $84,340 a year, or $40.55 an hour, per BLS OEWS May 2025, with the middle half between $79,400 and $94,830 and a full range of $65,700 to $97,220. That is 14.0% below the $98,100 national median. Because part-time work is common in this occupation, the hourly figure is often the more useful comparison.

Charleston-North Charleston at $94,570, followed by Hilton Head Island-Bluffton at $90,660. Greenville-Anderson-Greer at $85,290, Spartanburg at $83,780 and Columbia at $82,370 trail well behind. The coastal premium of eight to twelve thousand dollars is the largest geographic lever in this occupation in South Carolina, though coastal housing costs absorb part of it.

Through the Board of Dentistry at the Department of Labor, Licensing and Regulation. You need a CODA-accredited dental hygiene programme, a passing score on the national written examination and a board-accepted clinical examination. Administering local anaesthesia requires a separate board authorisation, and that is the addition most worth having — it broadens what a practice can bill for your chair time and is standard in periodontal-heavy practices.

In defined settings, yes. South Carolina permits hygienists to provide preventive services in public health and school settings under general rather than direct supervision, which is how the state extends care into rural counties where dentist coverage is thin. In private practice the standard supervision requirements apply. The public health route is a genuine option for hygienists who want a different kind of practice, though it does not generally pay at the coastal private-practice rate.

Because the $65,700 tenth percentile is measuring part-time and partial-year schedules rather than full-time entry pay. It sits nearly fourteen thousand dollars below the 25th percentile of $79,400 — a step far larger than any other in the band — and dental hygiene has one of the highest voluntary part-time rates of any licensed health occupation. A full-time South Carolina hygienist should be reading the $79,400 to $94,830 range as the realistic market, and the $40.55 hourly median as the cleaner benchmark.

Partly. Charleston at $94,570 pays about twelve thousand dollars more than Columbia at $82,370, which is a substantial difference in an occupation whose full band spans only about thirty-one thousand. But Charleston and Hilton Head are the two most expensive housing markets in South Carolina, and a good share of that premium is compensation for the cost of living there rather than a real gain. The nuance worth knowing is that South Carolina's low assessment ratio on owner-occupied property softens the coastal housing cost more than it would in most states — the annual carrying cost of a Charleston house is lower relative to its price than the sticker figure implies.

Part-time work, and the compression at the top. Dental hygiene annual wage series blend full-time and part-time workers, which is what produces the very low $65,700 tenth percentile; the $40.55 hourly median is the number to negotiate against. At the other end, the 75th percentile of $94,830 and the 90th of $97,220 are barely twenty-four hundred dollars apart, which means the upper quartile is effectively the ceiling of employed hygiene practice in this state. The figure also excludes production bonuses that some practices use.

The coastal markets first — Charleston at $94,570 or Hilton Head at $90,660 against Columbia at $82,370. The local anaesthesia authorisation second, because it changes what you can do chairside and what a practice can bill. Periodontal and specialist practices third, where the procedure mix supports a higher rate. Beyond that, adding days or covering temporary assignments across multiple practices is the main way South Carolina hygienists increase annual earnings, given how tight the top of the band is — and it is worth negotiating on the hourly rate, since that is what actually varies.
