How Often Should You Really Go to the Dentist?

By Dr. Jane Collins | November 12, 2025

We’ve all heard the rule since childhood: 'Visit your dentist twice a year.' For many, this six-month interval is the golden standard of oral hygiene. But is it really a one-size-fits-all requirement? The answer, like most things in healthcare, is unique to your specific body and history.

Where Did the 'Six-Month Rule' Come From?

Interestingly, the biannual recommendation didn't originate from modern clinical studies, but rather from early public health campaigns. However, it has stuck around because it works very well for the average person. Six months is typically the amount of time it takes for plaque to harden into tartar (calculus) that can no longer be removed by brushing alone.

Even with perfect brushing and flossing, tartar builds up in hard-to-reach areas. A professional cleaning is the only way to remove it before it causes gum inflammation.

Who Needs to Go More Often? (High-Risk Groups)

For many patients, twice a year isn't enough. Your dentist might recommend visits every 3 or 4 months if you fall into a high-risk category. This isn't about upselling services; it's about preventing irreversible damage. You may need more frequent visits if:

You have Gum Disease: If you have been diagnosed with gingivitis or periodontitis, you are prone to rapid bacteria buildup.
You Smoke or Use Tobacco: Tobacco use significantly increases the risk of gum disease and oral cancer.
You are Pregnant: Hormonal changes during pregnancy can cause 'pregnancy gingivitis.'
You are Diabetic: Diabetes can lower your resistance to infection, making gum disease more severe.

Can Anyone Go Less Often?

If you have impeccable oral hygiene, no history of cavities, and healthy gums, your dentist might suggest that once a year is sufficient. However, this is rare. The risk of skipping a visit is that small problems (like a tiny cavity or early gum recession) can turn into major, expensive procedures if left unchecked for 12 months.

The Verdict

The schedule should be determined by your dentist, not your insurance plan. After your next exam, ask your doctor: 'Based on my specific oral health, how often do you need to see me?'

Prevention is always cheaper and less painful than treatment. Don't wait for a toothache to schedule your next visit.
