What the record tells you
Discovery Dental, the trading name of Al Khayyat D D S INC, is an NPI registry record for a dental organization at 825 W San Marcos Blvd in San Marcos, California 92078. CMS issued NPI 1235026097 on 23 June 2025, and the practice last updated its own entry on 23 June 2025. That is recent, so the contact details are likely to be current.
It is registered under 2 dental taxonomy codes: General practice dentistry (1223G0001X), 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 7 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.
San Marcos holds 68 registered dental practices inside the San Diego-Chula Vista-Carlsbad, CA area, which has 1,588 in total on the California side and ranks 4th in the state. 44 of the San Marcos records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 60.5%, dental clinic or center 21.8%, pediatric dentistry 6.7%. The closest other registered practices are San Marcos Orthodontics (0 miles, San Marcos), San Marcos Smile Dental (0.2 miles, San Marcos) and Stellar Orthodontics (0.2 miles, San Marcos), with 2 more inside 0.3 miles.
On our figures a routine adult cleaning in California runs $130 to $200 cash and scaling and root planing $200 to $330 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 (760) 471-2231 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. It is not a review, an endorsement or a check on Discovery Dental.
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.
