Dental Cleanings: 4 Important Things to Know!

Patients usually note how smooth their teeth feel after dental cleanings. Additionally, if they tend to accumulate stain on their teeth, the increased whiteness after a cleaning is a desirable outcome as well. However, much of the benefit of a dental cleaning happens in areas we don’t even see. Below, I will discuss the benefits of a dental cleaning as well as how often we should be having them.

What does a Dental Cleaning consist of?

During a dental cleaning, a Registered Dental Hygienist will remove plaque and tartar from under your gums. This is called “scaling” and it comprises the majority of time taken during a cleaning appointment. “Scaling” typically involves use of both hand tools and a power washer or “Cavitron”. A hygienist also polishes your teeth during a cleaning.

Where necessary, a Hygienist may recommend application of fluoride to make your teeth more resistant to cavities. They may also measure the depth of your gum pockets at a cleaning appointment. If you are due for a checkup, your Family Dentist will examine your teeth.

How much does a Dental Cleaning cost?

The cost of a dental cleaning can vary greatly. The reason is that scaling and polishing are billed according to the amount of time (or number of “units”) taken to provide complete service. Units are 15 minute packets of time. If a hygienist scales your teeth for 30 minutes, that is 2 units of time. Some people build more tartar and hard plaque between cleanings. Consequently, they would require a great number of units of scaling compared to a patient with little tartar on their teeth.

With respect to polishing, a patient that builds more stain on their teeth between cleanings would typically require more polishing time to remove all stain. Thus some variability exists between patients in terms of how much scaling and polishing they require at dental cleanings.

A unit of scaling in the 2019 Ontario Dental Association (ODA) Fee Guide is $57. 2 units of scaling costs $114. An additional half unit of scaling costs $29. The most commonly billed number of units scaling for an adult cleaning is 2.5. If we call that a cleaning for the average adult, you are looking at a cost of $143. With a unit of polish ($31) added on, you are looking at approximately $174.

Other items that may add cost to a cleaning appointment include dental x-rays, fluoride application, and a checkup or recall exam.

The amounts I provide above are meant as a guideline. I cannot guarantee that your Family Dentist follows the ODA Fee Guide (and they are certainly entitled to set their own fees). Your best course of action is to get a cost estimate from your Dentist for these services.

What are the benefits of regular cleanings?

Regular dental cleanings have a number of benefits. They remove stain, brighten your teeth, and make everything feel smooth again. However, there are other massive benefits that you may not be able to see or feel:

  1. Removal of plaque and tartar from your gum pockets. You can’t feel the plaque and tartar buildup underneath your gums, but it’s there. It takes about 90 days after a cleaning for bacteria to buildup at the bottom of a gum pocket. These bacteria cause inflammation and can result in deepening of gum pockets. Cleaning these pockets keeps inflammation down. This helps to prevent deepening of gum pockets.
  2. Improvements to your systemic health. There is an abundance of evidence that bacteria can enter your circulatory system through your gums. These bacterial deposits have been linked to circulatory problems like atherosclerosis. With regular dental cleanings, you keep bacteria loads in proper balance. Even though you don’t feel it, the cleanings are making your whole body much healthier!
  3. Regular surveillance. Cleaning appointments allow for you to request a checkup by your Family Dentist. Additionally, your Dental Hygienist can advise you if they see any areas for concern. This might be a cavity (requiring a dental filling) or gum recession where treatment or a change in your home care can make a big difference! When you do not go for regular cleanings, you don’t know if certain areas are deteriorating. Sometimes a simple change in home care habits is all it takes to prevent a major problem.

How often should I have a Dental Cleaning?

The answer to this question depends on a number of factors. Generally, a patient that brushes 2-3 times daily while flossing 1-2 times daily can wait 6 months between cleanings. This is the most common “recall” or “re-care” interval. However, if you are in a high-risk group for cavities, gum disease, or both, you should see your Family Dentist more frequently (typically every 3-4 months). High-risk groups include:

  • Smokers (higher risk of gum disease or Periodontitis)
  • People with poorly controlled Diabetes (higher risk of Periodontitis and oral infections)
  • Patients with active gum disease
  • People with “dry mouth” or Xerostomia (higher risk of both Periodontitis and Cavities)
  • Patients who build plaque and calculus rapidly
  • People who frequently develop cavities
  • Patients going through orthodontic treatment with braces or Invisalign (higher risk of cavities)

Importantly, the recommended dental cleaning interval may change for a single individual through their lifetime. Consult your Family Dental Clinic to find out what interval would best suit you.
