How Often Should You Really Get a Dental Cleaning?

You've heard "every six months" your whole life. But where did that advice come from — and is it actually right for you?

The Origin of the Six-Month Rule

Dr. G recommends coming in every six months — not because it is a rule, but because catching a small problem early is almost always faster, easier, and cheaper than fixing a big one later. As he puts it: the exams where everything looks good are his favorites, because they are quick, easy, and you are back out the door.

Who Needs Cleanings More Often?

Patients with active or recently treated gum disease are typically placed on a 3–4 month maintenance schedule to prevent recurrence. Others who often benefit from more frequent visits include smokers, people with diabetes, those who tend to accumulate heavy tartar quickly, and patients with a consistent history of new cavities. Pregnancy also increases gum disease risk, making more frequent monitoring worthwhile during that period.

Who Might Be Fine with Once a Year?

A smaller group of patients — those with excellent home care, consistently clean exams, stable gum health, and low cavity risk over many years — may maintain their oral health well with annual visits. This is the exception, not the rule. It should be a decision made with your dentist based on a track record of exam results, not an assumption you make on your own.

What Happens at a Cleaning?

A routine cleaning (prophylaxis) involves scaling to remove plaque and tartar from all tooth surfaces including just below the gumline, polishing to remove surface stains, and a comprehensive exam that includes X-rays and an oral cancer screening. The whole process typically takes 60–75 minutes for an established patient. First-visit appointments take a bit longer due to the full health history review and baseline X-rays.

My Insurance Covers a Free Cleaning — Can I Just Book That?

It depends on the health of your gums. Dental insurance typically covers two routine cleanings per year — but those are designed for patients with healthy gums and no active gum disease. If we find signs of periodontal disease at your exam, a routine cleaning isn't the appropriate treatment. You'd need a deeper cleaning called scaling and root planing, which is a different procedure with different insurance coverage and out-of-pocket costs.

We always do a full exam before any cleaning so we know exactly what your mouth needs. We'll explain what we find and walk you through your options and costs before any treatment begins — no surprises.

The Bottom Line

Every six months is the right starting point for most adults — but it's exactly that: a starting point. At your first visit, your dentist will evaluate your individual risk factors and recommend a schedule that fits your actual oral health needs. If you haven't been in recently, the most important step is simply booking the appointment and letting us take it from there.
