Most Calgary adults should get a professional dental cleaning every six months — but that’s not a one-size-fits-all rule. Your ideal cleaning frequency depends on your personal oral health history, risk factors for gum disease, and how well plaque and tartar accumulate between visits. A licensed dentist or registered dental hygienist can assess your needs and recommend the schedule that’s right for you.
Why the “Twice a Year” Guideline Exists
The recommendation for biannual cleanings — also called prophylaxis — has been standard dental practice for decades, and for good reason. Professional cleanings remove calculus (tartar), the hardened mineral deposit that forms when dental plaque is left on tooth surfaces long enough to mineralise. No amount of brushing or flossing at home can remove calculus once it forms — only a licensed dental hygienist using specialised scaling instruments can do that safely.
Beyond removing calculus, a professional cleaning appointment typically includes:
- Supragingival and subgingival scaling (above and below the gumline)
- Tooth polishing to remove surface stains
- Periodontal pocket depth measurements
- Fluoride treatment (when recommended)
- Oral cancer screening
These appointments also give your dentist a regular opportunity to catch early signs of dental caries (cavities), gingivitis, and other conditions before they progress into more costly or complex problems.
When Every Six Months Isn’t Enough
For some patients, six months is simply too long to wait between cleanings. If you’ve been diagnosed with periodontal disease (gum disease), your dentist may recommend a more intensive cleaning schedule — often every three to four months. This type of care is called periodontal maintenance, and it’s designed to prevent the further destruction of the bone and soft tissue that support your teeth.
You may benefit from more frequent professional cleanings if you:
- Have a history of periodontal disease or have undergone scaling and root planing
- Are a current or former smoker (tobacco use significantly increases tartar build-up and periodontal risk)
- Have diabetes, which is strongly linked to increased susceptibility to gum infections
- Are pregnant — hormonal changes can cause pregnancy gingivitis, increasing inflammation and bleeding of gum tissue
- Have a dry mouth condition (xerostomia), which reduces saliva’s natural protective effect
- Wear orthodontic appliances or have bridgework and dental implants that require extra cleaning attention
When Once a Year May Be Appropriate
On the other end of the spectrum, some patients with excellent oral hygiene, low cavity risk, and no signs of periodontal disease may be suitable candidates for annual cleanings. However, this is relatively uncommon and should only be determined after a thorough clinical assessment — not assumed. Even patients with pristine home care can develop conditions that are only detectable through clinical examination and dental X-rays.
What Happens If You Skip Cleanings?
Going more than a year without a professional cleaning allows calculus to accumulate both above and below the gumline. Over time, this leads to chronic gingivitis, which — if untreated — can advance to periodontitis, a serious infection that destroys the bone supporting your teeth. Research consistently links untreated periodontal disease to systemic health conditions including cardiovascular disease, diabetes complications, and preterm birth.
In short, skipping cleanings doesn’t just affect your smile — it can affect your overall health.
What to Expect at a Cleaning Appointment in Calgary NW
At a typical cleaning visit, your dental hygienist will begin with a review of your medical history and any changes to your medications or health since your last visit. They’ll then perform a thorough assessment of your gum tissue, check for signs of cavities, and complete the professional cleaning. If it’s been a while since your last visit, the appointment may take longer or be split across two appointments — particularly if significant calculus removal is required.
Dental X-rays (radiographs) are typically taken annually or every 18 to 24 months to monitor for decay between teeth, bone levels, and other conditions not visible to the naked eye.

Frequently Asked Questions
How often should I get my teeth cleaned in Calgary?
Most licensed dentists in Calgary recommend a professional dental cleaning every six months for adults with good oral health. If you have a history of gum disease, smoke, or have certain medical conditions like diabetes, your dentist may recommend cleanings every three to four months instead.
Is it really necessary to get a dental cleaning twice a year?
For most adults, yes — biannual cleanings allow your dental hygienist to remove calculus (hardened tartar) that brushing and flossing cannot eliminate at home. These visits also give your dentist the chance to catch early signs of cavities, gingivitis, and oral cancer before they become more serious problems.
What happens if I only get my teeth cleaned once a year?
For some low-risk patients with excellent oral hygiene, annual cleanings may be sufficient, but this should only be determined by your dentist after a clinical assessment. Skipping regular cleanings allows calculus to build up below the gumline, which can lead to gingivitis and eventually periodontitis, a more serious form of gum disease.
How often do I need a dental cleaning if I have gum disease?
If you've been diagnosed with periodontal disease, your dentist will typically recommend cleanings every three to four months — a schedule known as periodontal maintenance. This more frequent care helps prevent further bone and tissue loss around your teeth and keeps the condition from progressing.
Does pregnancy affect how often I should get a dental cleaning?
Yes — pregnant women are at increased risk of pregnancy gingivitis due to hormonal changes that make gum tissue more sensitive and prone to inflammation. Licensed dentists often recommend that pregnant patients maintain their regular cleaning schedule or even increase the frequency during pregnancy to protect both oral and overall health.
How long does a professional dental cleaning take?
A routine cleaning appointment typically takes between 45 minutes and one hour, including the hygiene assessment, scaling, polishing, and any necessary X-rays. If it has been a long time since your last cleaning or there is significant calculus build-up, the process may take longer or be spread across two appointments.
