How many quadrants
Gum disease is often localised. Two quadrants cost roughly half of a full mouth, and the exam is charged once.
Cost guide
How much does a deep cleaning cost?
Scaling and root planing usually costs $185 to $350 per quadrant in Wisconsin, so a full mouth runs roughly $600–$1,400 across two visits. It is a periodontal treatment for gum disease, not a routine cleaning.
The bill, itemised
What's actually in the price
Deep cleaning is billed by quadrant because each quadrant is a separate appointment with its own numbing and charting.
Component What it is Typical range
Exam and X-rays Pocket depths, bone loss and a treatment plan $50–$250
First quadrant Scaling and root planing, four or more teeth $185–$350
Each extra quadrant Usually done at a second visit $150–$300
Local anaesthetic Normally included in the quadrant fee $0–$150
Periodontal maintenance A 3–4 month cleaning after treatment $100–$200
Typical full mouth (four quadrants) $600–$1,400
What moves the price
The per-quadrant fee is steady; what changes is how many quadrants need it and how far the disease has gone.
How deep the pockets are
Pockets of 5 mm or more with bleeding take longer than 4 mm. Advanced cases may add laser therapy or antibiotics.
One visit or two
Most practices split the mouth into two appointments so you can eat on one side; doing it in one sitting costs the same but is harder to tolerate.
Who does it
A hygienist working under a dentist is the usual and least expensive route. A periodontist charges more and is the right call for advanced bone loss.
Insurance
Does insurance cover a deep cleaning?
Usually yes, as a basic periodontal service at 50–80%, once your plan has the pocket-depth charting it asks for. Some plans require pre-authorisation.

Questions
What people ask before booking
Short answers to the questions that come up most. Every answer is checked against published fee surveys, not clinic marketing.
How is this different from a regular cleaning?
A routine cleaning removes plaque and tartar above the gumline. A deep cleaning goes below it, onto the root surface, and is only done when pockets are 4 mm or deeper with bleeding or bone loss.
Is it painful?
Each quadrant is numbed, so the appointment itself is usually comfortable. Most people have two to five days of sensitivity to cold and tender gums afterwards.
Why is it split into two visits?
Numbing both sides of the mouth at once makes eating and speaking awkward for hours. Two visits also let the clinician spend proper time on each side.
What happens if I skip it?
Gum disease does not reverse on its own. Untreated pockets deepen, bone is lost, and the eventual cost is extractions and implants rather than a $600–$1,400 cleaning.
Does dental insurance cover a deep cleaning?
Part of it, usually. Most plans cover deep cleanings at a set percentage after a deductible, up to an annual maximum that is typically $1,000–$2,000. Ask for a pre-treatment estimate before you book.
Can I get it cheaper at a dental school?
Often, yes. Dental schools treat patients under supervision at reduced fees in exchange for longer appointments; Marquette University in Milwaukee is the nearest option for most of Wisconsin.
