What the record tells you
Sohdental, the trading name of Soh of Missouri Samson Liu PC, is an NPI registry record for a dental organization at 810 Ofallon Rd Ste 80 in Weldon Spring, Missouri 63304. CMS issued NPI 1427550078 on 28 February 2018, and the practice last updated its own entry on 2 September 2025. That is recent, so the contact details are likely to be current.
It is registered under 2 dental taxonomy codes: Dentist (122300000X), Orthodontics and dentofacial orthopedics (1223X0400X). That puts it in 2 categories on this site, led by general dentistry. A practice that registers more than one category is telling CMS it does more than one kind of dental work at this address, which is why it has a page here rather than a row. No other address in the registry carries this name, though a practice trading under a chain brand often registers each office under its own legal name, so check the brand as well. One other dental record shares the street address: Dynasty Dental LLC.
Weldon Spring holds 5 registered dental practices inside the St. Louis, MO-IL area, which has 748 in total on the Missouri side and ranks 1st in the state. 4 of the Weldon Spring records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 62.8%, dental clinic or center 19.4%, orthodontics 7%. The closest other registered practices are Dynasty Dental LLC (0 miles, Weldon Spring), Weldon Spring Dental (0 miles, Weldon Spring) and Monticello Sleep Dentistry LLC (0.2 miles, Weldon Spring), with 2 more inside 1.4 miles.
On our figures a routine adult cleaning in Missouri runs $90 to $135 cash and scaling and root planing $165 to $255 per quadrant, against a US average of $125. This practice's own prices are not in the registry and never will be: NPPES holds identifiers, not fees. Call (636) 244-4052 and ask for the cash price on code D1110, whether the exam and X-rays are included, and whether they run a membership plan if you have no insurance.

What to ask when you call
- The cash price for D1110, a routine adult cleaning, and whether the exam (D0120) and X-rays (D0274) are inside or outside that number.
- Whether you need scaling and root planing before a routine clean, and the per-quadrant price for D4341 or D4342 if so.
- Whether they run an in-house membership plan, and what it covers against what it costs a year.
- Whether they are taking new patients and how far out the next hygiene appointment is.
- The practice license, with your state dental board. An NPI is a billing identifier and proves nothing about licensing.
CMS NPPES NPI data file, August 2026, snapshot 10 August 2026. US federal public data (FOIA-disclosable, no charge). CMS NPI files. NPI registry records, status as reported by CMS in the August 2026 data dissemination file. NPPES is an identifier registry, not a license register: an NPI does not validate that a practice is licensed, accredited or currently open. Practices maintain their own NPPES entries. Every page shows the date the record was last updated; addresses and phone numbers are as self-reported and are not verified by us. This page describes a registry record. It is not a review, an endorsement or a check on Sohdental.
Price figures are our own, last verified April 2026. State averages are our estimates compiled from FAIR Health regional cost data and CMS Medicare fee schedules; the ADA discontinued its national Survey of Dental Fees in 2023, so no national fee survey exists.
