The Ideology of the 6 Month Dental Cleaning
By Amanda Heilman, RDH
When it comes to dental health, you might have heard the following advice: “Visit your dentist every six months.” But have you ever wondered where this guideline came from? The 6-month cleaning interval isn’t rooted in solid scientific research; rather, it can be traced back to a clever marketing campaign in the early 1900s.
Claude Hopkins, an advertising pioneer, launched a campaign for Pepsodent toothpaste that linked tooth brushing to health and beauty. His catchy slogan, “Use Pepsodent every day – see your dentist twice a year,” established the norm for regular dental check-ups. While it certainly helped boost toothpaste sales, it also set a precedent that we still follow today.
The American Dental Association (ADA) recommends regular dental check-ups, but the frequency of cleanings should be personalized. Factors such as your risk of gum disease, family history, diabetes, and smoking can all influence how often you should see your dentist. For some, every six months is sufficient, for others, a visit every three or four months might be necessary.
Regardless of the interval, dental cleanings are crucial for maintaining good oral health. During a cleaning, your dentist or hygienist removes plaque, calculus, and stains that can accumulate on your teeth, even with diligent brushing and flossing. This approach helps prevent cavities and gum disease, keeping your smile bright and healthy. Routine check-ups allow your dentist to detect any potential issues early on. Catching problems while they’re small can save you from more extensive (and expensive) treatments down the line.
If your dentist or hygienist suggests more frequent cleanings, such as every three or four months, it’s important to understand that they have your best interests in mind. This recommendation isn’t about making more money; it’s about providing the best care for your individual health needs.

Maintaining your oral health is a lifelong commitment, and regular dental cleanings play a vital role. Whether you follow the 6-month rule or a different schedule, the key is to stay proactive and listen to your dental professionals. Your smile deserves it!
