How Often Should Calgary Adults Actually Get a Dental Cleaning?
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…
