What the record tells you
Plaza Dental Group, the trading name of Soh of Missouri Samson Liu PC, is an NPI registry record for a dental organization at 105 N Keene St Ste 100 in Columbia, Missouri 65201. CMS issued NPI 1528628716 on 19 June 2019, and the practice last updated its own entry on 28 September 2026. That is recent, so the contact details are likely to be current. CMS records it as a subpart of Soh of Missouri Samson Liu PC, so billing and pricing may follow the parent's policies.
It is registered under 2 dental taxonomy codes: General practice dentistry (1223G0001X), 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. The same registered name appears at 10 distinct addresses nationally. That is either a group practice or a name common enough that unrelated offices share it, so ask whether pricing is set locally or by a parent company.
Columbia holds 63 registered dental practices inside the Columbia, MO area, which has 68 in total on the Missouri side and ranks 4th in the state. 38 of the Columbia records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 61.8%, dental clinic or center 17.6%, pediatric dentistry 10.3%. The closest other registered practices are Parrott Dental LLC (0.2 miles, Columbia), Shelley Ann Lyle DDS PC (0.3 miles, Columbia) and Mary K Davis DDS LLC (0.3 miles, Columbia), with 2 more inside 0.3 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 (573) 817-2222 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, October 2026, snapshot 12 October 2026. US federal public data (FOIA-disclosable, no charge). CMS NPI files. NPI registry records, status as reported by CMS in the October 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 Plaza Dental Group.
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. Treat them as a starting point and call two or three offices for an actual quote.
