What the record tells you
Sequence Orthodontics is an NPI registry record for a dental organization at 23140 Moakley St Ste 3 in Leonardtown, Maryland 20650. CMS issued NPI 1205496726 on 17 June 2019, and the practice last updated its own entry on 17 June 2019. That was 7 years ago, so treat the phone number and the suite number as unconfirmed until someone answers. CMS records it as a subpart of Sequence Orthodontics, 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 orthodontics. 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 2 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. 2 other dental records share the street address: Breton Bay Dentistry and Pediatric Dentistry.
Leonardtown holds 8 registered dental practices inside the Lexington Park, MD area, which has 79 in total on the Maryland side and ranks 3rd in the state. 1 of the Leonardtown records also register orthodontics, so this is one of only a handful of local options in that category. Across the metro the mix runs general dentistry 60.8%, dental clinic or center 13.9%, orthodontics 12.7%. The closest other registered practices are Breton Bay Dentistry (0 miles, Leonardtown), Pediatric Dentistry (0 miles, Leonardtown) and Tongue Tie and Airway Center of Southern Maryland (0.9 miles, Leonardtown), with 2 more inside 1 miles.
On our figures a routine adult cleaning in Maryland runs $120 to $180 cash and scaling and root planing $190 to $300 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 (301) 997-0666 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 Sequence Orthodontics.
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.
