What the record tells you
Cosmetic & General Dentistry of Winthrop is an NPI registry record for a dental organization at 28 Old Western Ave in Winthrop, Maine 04364. CMS issued NPI 1407029184 on 2 April 2008, and the practice last updated its own entry on 2 April 2008. That was 18 years ago, so treat the phone number and the suite number as unconfirmed until someone answers.
It is registered under 2 dental taxonomy codes: Dental clinic or center (261QD0000X), General practice dentistry (1223G0001X). That puts it in 2 categories on this site, led by dental clinic or center. 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.
Winthrop holds 1 registered dental practice inside the Augusta-Waterville, ME area, which has 54 in total on the Maine side and ranks 3rd in the state. 1 of the Winthrop record also register dental clinic or center, so this is one of only a handful of local options in that category. Across the metro the mix runs general dentistry 48.1%, dental clinic or center 27.8%, orthodontics 13%. The closest other registered practices are Lakeside Dental LLC (5.5 miles, Manchester), Central Maine Dentistry (6.6 miles, Manchester) and Evergreen Dental Associates LLC (8.7 miles, Augusta), with 2 more inside 8.9 miles.
On our figures a routine adult cleaning in Maine runs $110 to $160 cash and scaling and root planing $180 to $275 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 (207) 377-6958 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.

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.

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.
