What the record tells you
Belmont Dental Group, LLC. is an NPI registry record for a dental organization at 57 Concord Ave in Belmont, Massachusetts 02478. CMS issued NPI 1700596103 on 28 November 2022, and the practice last updated its own entry on 8 December 2022. That was 3 years ago; the details are probably current, but confirm the address when you book.
It is registered under 2 dental taxonomy codes: Dentist (122300000X), Dental clinic or center (261QD0000X). 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 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.
Belmont holds 26 registered dental practices inside the Boston-Cambridge-Newton, MA-NH area, which has 3,202 in total on the Massachusetts side and ranks 1st in the state. 10 of the Belmont records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 58.7%, dental clinic or center 21.2%, orthodontics 8.2%. The closest other registered practices are AMG Family Dental (0 miles, Belmont), Schrott Perio Implants, LLC (0.1 miles, Belmont) and Belmont Prosthodontics (0.8 miles, Belmont), with 2 more inside 0.8 miles.
On our figures a routine adult cleaning in Massachusetts runs $145 to $225 cash and scaling and root planing $215 to $350 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 (617) 484-2431 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 Belmont Dental Group, LLC..
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.
