Patients smiling for a general dentistry guide

During dental scaling with an ultrasonic scaler, a hygienist guides a vibrating tip and a water spray around each tooth to break up plaque and hardened tartar. Expect water, a humming sound and a buzzing feeling, followed by hand instruments and polishing. Some sensitivity is possible, especially with inflamed gums or exposed roots, and the team can adjust as you go.

Key Takeaways

  • Dental scaling is the professional removal of plaque, tartar and stain. Ultrasonic scaling is one way to do it, often combined with hand instruments.
  • A visit usually starts with a health review and exam, not with the scaler.
  • Water, sound and vibration are normal parts of ultrasonic scaling. Raise a hand at any point if something is uncomfortable.
  • Mild sensitivity or tender gums afterward can happen. After a deep cleaning, ADA MouthHealthy notes pain for a day or two and sensitivity for up to a week are possible.
  • Brushing and cleaning between teeth should continue the same day unless you are told otherwise.

What is dental scaling?

Dental scaling is the professional removal of plaque, tartar (calculus) and surface stain from teeth, along the gumline and, when needed, below it. Tartar is plaque that has hardened with minerals from saliva, and ADA MouthHealthy notes that once tartar forms, only your dentist can remove it.

Dental scaling can be done with an ultrasonic scaler, with hand instruments, or both. At Landmark Dental Care, hygiene visits use the Cavitron, a brand name for an ultrasonic scaling device, together with hand scalers for finishing. The Cavitron's tip vibrates rapidly while a stream of water cools it and washes away loosened debris.

Routine scaling is different from scaling and root planing, often called a deep cleaning. A deep cleaning treats gum disease by removing deposits deeper under the gumline and smoothing the roots. This article focuses on routine and maintenance scaling, with notes on where a deeper cleaning differs. For the device itself, see our guide to what a Cavitron dental cleaning is.

Before scaling starts

A cleaning appointment begins with questions and a look at your mouth, not with the scaler tip. Expect the team to ask about:

  • changes to your health, medications or allergies since your last visit;
  • pregnancy, heart conditions, or implanted devices such as a pacemaker;
  • bleeding gums, sensitive teeth or any spot that hurts when you chew;
  • recent dental work, oral surgery, whitening or orthodontic appliances;
  • how past cleanings felt and whether anything made them difficult.

This review matters because it can change the plan. Instrument choice, intensity, pacing and appointment length may all be adjusted to your answers.

The hygienist or dentist then checks your teeth and gums, looking at plaque, tartar and inflamed areas. Some visits include gum measurements (periodontal charting) to track pocket depths. X-rays are taken only if they are needed to check an area of concern; the Canadian Dental Association notes that a healthy adult without recent problems probably will not need X-rays at every appointment.

If you are anxious, have a strong gag reflex or want to agree on a stop signal, now is the time to say so. For how hygiene visits are offered at our practice, see Landmark Dental Care's professional cleaning page.

What happens during ultrasonic scaling, step by step

Once the assessment is done, the scaling itself follows a fairly predictable pattern. Here is what each stage usually looks and feels like.

Step What the clinician does What you may notice
1. Positioning Reclines the chair, places suction, may offer glasses Light in your eyes, a suction tip near your cheek
2. Ultrasonic scaling Guides the vibrating tip along each tooth, section by section Hum, buzzing, cool water, suction noise
3. Rechecking Pauses, clears water and looks at each area Brief breaks; a chance to swallow or rest
4. Hand finishing Uses manual scalers to remove what remains and check smoothness Light scraping, pressure, quieter
5. Polishing Removes surface stain with a paste Gritty texture, a smooth feel afterward
6. Fluoride (if recommended) Applies fluoride based on cavity risk A brief taste; follow any instructions about eating
7. Wrap-up Reviews findings and home care Tips for the spots that built up the most

The clinician usually works around the mouth in sections, spending more time where tartar is heavier. If buildup is significant, they may go over an area more than once, which can make the visit feel longer than a light maintenance cleaning.

Water

A steady spray of water cools the vibrating tip and flushes loosened debris away. Suction removes it from your mouth. You may be asked to turn your head slightly or close a little around the suction so water does not pool. Breathing through your nose helps.

Sound

The ultrasonic handpiece makes a hum or high-pitched whine. The sound is normal and does not mean a tooth is being damaged. If sound bothers you, ask whether you can wear earbuds or headphones.

Vibration

The tip vibrates against the tooth. It usually feels like buzzing or tickling. On an exposed root or an inflamed patch of gum it can feel sharper. That is useful information for the clinician, not something to endure in silence. Raise a hand or speak up, and they can pause, change the angle, adjust the intensity or switch to hand instruments.

Ultrasonic scaling is a professional procedure that depends on training in tip choice and technique. Home picks and gadgets are not a substitute, so leave tartar removal to your dental team.

Hand finishing, polishing and fluoride

After the ultrasonic portion, most appointments continue with hand instruments. Scalers and curettes give the clinician tactile feedback, so they can feel any small ledge of tartar left behind, especially between teeth, around fillings and crowns, and in tight spots.

Hand finishing does not mean the ultrasonic step failed. The Scottish Dental Clinical Effectiveness Programme (SDCEP) supports using powered instruments, manual instruments or a combination, and many clinicians use both. Our comparison of ultrasonic and hand scaling explains why.

Polishing usually comes next. A paste applied with a soft rotating cup removes surface stain and leaves teeth feeling smooth. Not every stain comes off in one visit, and polishing does not change the natural shade of your teeth or treat decay.

Fluoride may be offered at the end, depending on your cavity risk and age. It is a separate preventive step from scaling. If fluoride is applied, follow any instructions about eating or drinking afterward.

Before you leave, it is worth asking which areas needed the most attention and whether your recall interval should change. The CDA notes that how often you need dental visits depends on your individual oral health needs.

Sensitivity during and after dental scaling

Sensitivity during dental scaling is common enough to plan for. It is not a sign that you are doing anything wrong. Inflamed gums, gum recession, exposed roots, recent whitening, grinding and cracked teeth can all make vibration or cold water feel sharper.

During the visit, options may include:

  • slower pacing and more breaks;
  • lower intensity on sensitive teeth;
  • more use of hand instruments in sensitive areas;
  • a desensitizing product applied to specific teeth;
  • local anaesthetic for very sensitive areas, when appropriate.

Sensitivity that shows up on just one tooth deserves a mention. A cracked tooth, a failing filling or a localized gum problem can make that site react more than the rest of your mouth. Telling the clinician exactly where helps them decide whether to examine it before finishing.

After the appointment, teeth may feel sensitive to cold, sweet or air for a short time, and gums may feel tender when you brush. Gums that bled because they were inflamed can look irritated briefly while they heal. After a deep cleaning, ADA MouthHealthy notes that some pain for a day or two and sensitivity for up to a week can occur. If sensitivity lasts longer than that, let the office know.

No clinic can honestly promise that dental scaling will feel comfortable for everyone. Good care means asking, listening and adjusting.

Aftercare for the next few days

For most people, normal life resumes right after a routine cleaning. Here is a simple guide.

When What to do Call the office if
Right after Eat and drink normally unless told otherwise; wait if you were numbed Numbness lasts much longer than expected
That evening Brush gently with a soft brush; clean between teeth Bleeding does not stop with light pressure
Next 1–3 days Use a desensitizing toothpaste if suggested; avoid very cold drinks if they sting Pain is getting worse, not better
Following weeks Keep up daily brushing and cleaning between teeth Sensitivity persists or is limited to one tooth
Next visit Return at the recall interval your team recommends Any new swelling, bleeding or loose teeth

A few practical tips:

  • Keep brushing and flossing. Plaque begins forming again within hours. Skipping home care because your teeth feel clean lets it build up faster.
  • Be gentle, not absent. If your gums are tender, use a soft brush and careful flossing, but still remove plaque.
  • Follow product directions. If a desensitizing toothpaste or rinse was suggested, use it as directed.
  • Skip home remedies. Do not place aspirin, acidic mixtures or household products on your gums.

Facial swelling, fever, difficulty swallowing or pain that keeps getting worse are not expected after routine scaling. Call the office for assessment. If swelling is spreading or you have trouble breathing or swallowing, call 911 or go to the Emergency Department at the Colchester East Hants Health Centre in Truro. You can also call 811 for nurse advice at any time.

Special situations

Children. Many children have little tartar, and scaling may be brief or done by hand. The water and sound can surprise a child, so a quick demonstration helps. In Nova Scotia, the Children's Oral Health Program covers scaling among its services for eligible children aged 14 and younger with a valid health card.

Pregnancy. Hormone changes can make gums more likely to bleed and swell. Cleanings remain part of normal care during pregnancy. Tell the team so they can plan positioning and any X-ray decisions.

Pacemakers and implanted cardiac devices. The American Dental Association notes that evidence on ultrasonic scalers and cardiac devices is mixed and that guidance recommends keeping the handpiece at a distance from the device and consulting a cardiologist when there is concern. Bring your device details so the team can plan, which may include hand instruments instead.

Seniors and dry mouth. Medications that dry the mouth can speed up plaque and tartar buildup. Exposed roots are more common with age and can be more sensitive.

Dental anxiety. Agree on a stop signal, ask for breaks and let the team know if sound, water or pressure bothers you most.

Implants, crowns and braces. These may need specific tips or hand instruments. Mention any dental work you have had elsewhere.

How long dental scaling takes and what affects cost

How long dental scaling takes depends on the amount and location of tartar, your gum health, how sensitive your teeth are and whether an exam, X-rays, polishing and fluoride are included. A light maintenance cleaning is usually shorter than a first visit after a long gap. If you need to plan around a time limit, ask when booking.

Cost follows the same factors. This article does not list prices, but these usually make a difference:

  • how much tartar needs to be removed and how long that takes;
  • whether it is a routine cleaning or periodontal therapy such as scaling and root planing;
  • which other services happen at the same visit;
  • how long it has been since your last cleaning.

As of 2026, the Government of Canada lists cleaning (scaling) among the preventive services covered by the Canadian Dental Care Plan, with cost-sharing based on family income. Call the office to confirm current CDCP participation and billing, and see our CDCP page for more. Private plans vary, so check your plan's limits on scaling. If a deeper cleaning is recommended, our guide to regular cleaning versus deep cleaning explains how the two differ.

FAQ

How long does dental scaling take?

It depends on how much tartar there is, your gum health and what else is included in the visit. A light maintenance cleaning is usually quicker than a first cleaning after a long gap, so ask when booking if you need to plan your time.

Is it normal for my teeth to feel sensitive after scaling?

Yes, mild sensitivity to cold or tender gums can happen, especially around exposed roots or previously inflamed gums. Call the office if pain is severe, keeps getting worse or comes with swelling.

Why is there so much water during ultrasonic scaling?

The water cools the vibrating tip and flushes loosened plaque and tartar out of the area. Suction removes it so you can breathe comfortably; breathing through your nose helps.

Can I eat after dental scaling?

Usually, yes. Most people can eat and drink normally after a routine cleaning. If fluoride was applied or you were numbed, follow the team's instructions and wait until feeling returns before chewing.

Can I brush and floss after dental scaling?

Yes. You can brush and clean between your teeth the same day unless your team tells you otherwise. If gums feel tender, use a soft brush and a gentle touch, but keep removing plaque so it does not build up again.
