What the record tells you
Mavis Ng DMD Comprehensive Dentistry PLLC is an NPI registry record for a dental organization at 840 Hanshaw Rd Ste 14 in Ithaca, New York 14850. CMS issued NPI 1588356257 on 22 May 2023, and the practice last updated its own entry on 7 June 2023. 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: Oral and maxillofacial surgery (1223S0112X), Dental clinic or center (261QD0000X). 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.
Ithaca holds 22 registered dental practices inside the Ithaca, NY area, which has 25 in total on the New York side and ranks 11th in the state. 5 of the Ithaca records also register dental clinic or center, so this is one of several local options in that category. Across the metro the mix runs general dentistry 56%, dental clinic or center 20%, orthodontics 20%. The closest other registered practices are Cayuga Family Dental LLC (0.7 miles, Ithaca), Tompkins Dental Health, PC (1 miles, Ithaca) and Tompkins Bright Dental PLLC (1 miles, Ithaca), with 2 more inside 1.1 miles.
On our figures a routine adult cleaning in New York runs $150 to $250 cash and scaling and root planing $225 to $370 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 (607) 257-2322 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.

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.
