A cleaning is one of the least expensive appointments in dentistry, and it prevents some of the most expensive ones. Here is exactly what happens in the chair, how we decide which kind of cleaning you need, and how often you should come back.

What is a dental cleaning?

A professional cleaning removes the two things a toothbrush cannot: plaque that has hardened into tartar (calculus), and bacteria that have collected just under the gumline. Once plaque mineralizes into tartar — which starts happening within days — no amount of brushing or flossing will take it off. It has to be removed with instruments.

At its core the visit is two steps: scaling, where a hygienist uses hand instruments and an ultrasonic scaler to break up and lift the deposits, and polishing, where a soft rubber cup and a mildly abrasive paste remove what is left without damaging enamel.¹

But a cleaning appointment is never only a cleaning. It is also the appointment where problems get found early — while they are still small, painless, and cheap to fix.

• An exam for decay, cracked teeth, and failing fillings or crowns
• A gum evaluation, where pocket depths are measured around each tooth
• X-rays when they are needed, to see what the eye cannot
• An oral cancer screening — a visual and tactile check of the tongue, mouth, jaw and neck, which the ADA reaffirmed in 2026 as the foundation of early detection²
• Fluoride, sealants, or specific home-care coaching where they will help

Gum disease is common, quiet, and preventable

Periodontal disease rarely hurts until it is advanced. That is what makes it dangerous: by the time a tooth feels loose, bone has already been lost, and bone does not grow back on its own. The numbers are worth knowing.

Gum disease is the leading cause of tooth loss in American adults. Beyond the mouth, keeping plaque and inflammation under control is associated with lower risk of several systemic conditions, including heart disease and stroke. Regular cleanings are among the most effective ways to interrupt that process early — and among the least invasive.

The four kinds of cleaning, from preventive to therapeutic

Most people assume “a cleaning” means one procedure. It doesn't. There are several, and the four below cover most cases. Which one you need is a clinical finding — based on your pocket depths, your X-rays and the amount of buildup present — not a matter of preference or budget. We measure first, then tell you what we found and why.

What to expect at your cleaning

A routine visit runs 30 to 60 minutes. In order:

1. Health history and a look around

We review anything that has changed — new medications, a new diagnosis, pregnancy, a heart condition — because all of it affects your mouth and how we treat it. Then a visual and tactile exam, including the oral cancer screening.

2. Measuring your gums

A thin probe checks the pocket depth around each tooth and where the tissue bleeds. This is the record that tells us whether things are stable, improving, or getting worse since last time.

3. X-rays, if they are due

Not at every visit. Only when the exam, your history, or the interval calls for them — to catch decay between teeth and to check the bone level around the roots.

4. Scaling

An ultrasonic scaler breaks up the larger deposits with vibration and a water spray; hand instruments finish the detail work along each surface and just under the gum margin. You will hear scraping. It should not hurt — tell us if it does.

5. Polishing and flossing

A soft rubber cup with prophy paste lifts remaining stain and bacteria, then everything is flossed and rinsed above and below the gumline.

6. Findings, fluoride, and a plan

We go over what we found, apply fluoride varnish if it will help, and set your next interval — six months for most people, shorter if your gums or your risk factors say so.
