What the record tells you
New Concepts Dental Group, the trading name of Janet S Krefting DDS & Richard W. Waldman DMD, PC, is an NPI registry record for a dental organization at 330 Boston Rd, Unit 16 in N Billerica, Massachusetts 01862. CMS issued NPI 1114123577 on 22 June 2007, and the practice last updated its own entry on 11 September 2025. That is recent, so the contact details are likely to be current.
It is registered under 2 dental taxonomy codes: Dentist (122300000X), Periodontics (1223P0300X). That puts it in 2 categories on this site, led by periodontics. 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. One further NPI is registered to what looks like the same business at this address (New Concepts Dental Group, NPI 1053564633); it is covered by this page rather than given a page of their own.
N Billerica holds 1 registered dental practice inside the Boston-Cambridge-Newton, MA-NH area, which has 3,202 in total on the Massachusetts side and ranks 1st in the state. 1 of the N Billerica record also register periodontics, so this is one of only a handful of 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 New Concepts Dental Group (0 miles, No. Billerica), Charles C Hur DMD PC (0.1 miles, North Billerica) and North Billerica Smiles, LLC. (0.1 miles, North Billerica), with 2 more inside 0.2 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 (978) 663-7638 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 New Concepts 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.
