Most people know they should get their teeth cleaned twice a year — but do you know why? Learn what happens during a professional cleaning and why it's the foundation of good oral health.
What Happens During a Professional Dental Cleaning?
A professional dental cleaning — also called a prophylaxis — is much more than a quick polish. Your dental hygienist uses specialized instruments to remove calculus (tartar) that has hardened on your teeth, which cannot be removed by brushing and flossing alone.
The cleaning process includes scaling (removing tartar above and below the gumline), polishing (removing surface stains and smoothing tooth surfaces), and flossing between every tooth. Your hygienist will also measure your gum pocket depths to check for signs of gum disease.
Why Twice a Year Is the Standard Recommendation
The American Dental Association recommends professional cleanings every six months for most patients. This interval is based on how quickly plaque mineralizes into tartar — typically within 24–72 hours — and how long it takes for bacterial buildup to cause significant damage.
For patients with a history of gum disease, diabetes, or other risk factors, more frequent cleanings (every 3–4 months) are often recommended. Dr. Gong will assess your individual risk and recommend the cleaning interval that's right for you.
The Connection Between Oral Health and Overall Health
Research has established strong links between gum disease and systemic conditions including heart disease, diabetes, stroke, and pregnancy complications. The bacteria responsible for gum disease can enter the bloodstream and trigger inflammatory responses throughout the body.
Regular cleanings reduce the bacterial load in your mouth and help prevent the chronic inflammation associated with these systemic health risks. Maintaining good oral health is genuinely good for your overall health.
What Happens If You Skip Cleanings?
When tartar is allowed to accumulate, it creates a rough surface that harbors bacteria and accelerates gum disease progression. Gingivitis (early gum disease) can progress to periodontitis, which destroys the bone and tissue that support your teeth — ultimately leading to tooth loss.
The cost of treating advanced gum disease, replacing lost teeth, or addressing the systemic health consequences of chronic oral infection far exceeds the cost of regular preventive cleanings. Prevention is always the better investment.
