How often does insurance cover D1110?

Usually twice a year (about once every six months) under preventive benefits, often at or near full coverage.

How much does a D1110 cleaning cost?

Often around 75 to 200 USD depending on location and office, though many plans cover it fully as preventive care.

What's the difference between D1110 and a deep cleaning?

D1110 is a routine cleaning for a healthy mouth. A deep cleaning (scaling and root planing) treats active gum disease and uses different codes.

Is there a separate cleaning code for children?

Yes. A child prophylaxis is reported with D1120. The choice between D1110 and D1120 depends on the patient's age and dentition.

Does D1110 include the exam and X-rays?

No. The cleaning, the exam, and any X-rays are separate codes, even when performed at the same visit.

D1110 Dental Code: Adult Cleaning (Prophylaxis)

Code Summary

D1110 is the CDT code for an adult prophylaxis — the routine professional cleaning that removes plaque, tartar, and stain from your teeth to keep your gums healthy. It's the standard "cleaning" most adults get at their recall visit.

What D1110 means

D1110 covers a routine cleaning for an adult patient. "D" is dental, "11" is the prophylaxis group, and "10" is the adult version. A hygienist or dentist removes soft plaque and hardened tartar from above the gumline, then polishes the teeth. It's a preventive service aimed at stopping gum disease before it starts.

It's usually performed at the same visit as your exam and any recall X-rays, though each is coded separately. There's a matching child cleaning code (D1120) for younger patients, so the right one depends on the patient's age and dentition.

The most important distinction is D1110 versus a deep cleaning. A routine prophylaxis treats a basically healthy mouth. If there's active gum disease with deeper pockets, that calls for scaling and root planing or periodontal maintenance (D4910) — different procedures with different codes. Billing a routine cleaning when periodontal treatment was actually done is a common coding error.

When it's typically used

D1110 is reported for adults at routine preventive visits — commonly twice a year — when the mouth is generally healthy and the cleaning is for maintenance rather than treatment of active gum disease.

How much does D1110 cost?

An adult cleaning is a modest fee, often roughly 75 to 200 USD depending on region and office. It's frequently part of the bundle patients think of as their twice-yearly visit, alongside the exam and X-rays.

Is D1110 covered by insurance?

Most plans cover routine cleanings under preventive care, very often at or near 100 percent, but limit them to two per year (sometimes once every six months). Periodontal patients may fall under different coverage rules for maintenance cleanings.
