You have probably heard the advice since childhood: visit the dentist twice a year. But is that really enough for everyone? The answer, according to current research and the clinical experience of our team at Westar Dental, is that it depends on your individual risk factors. Some patients thrive with two cleanings per year, while others benefit significantly from three or even four.
Dr. Hanul Oh take a personalized approach to preventive care at our Westerville, OH practice. This guide explains the science behind cleaning frequency, helps you understand your own risk profile, and walks you through what happens during a professional dental cleaning and exam.
The Standard Recommendation: Twice a Year
The American Dental Association recommends that most adults visit the dentist at regular intervals determined by their dentist, which for many healthy patients works out to every six months. This schedule is based on the rate at which plaque and tartar accumulate on teeth and the time it takes for early-stage gum disease to develop if left unchecked.
For a patient with good oral hygiene habits, no history of gum disease, and no significant risk factors, a cleaning every six months is generally sufficient to maintain optimal oral health. During each visit, the hygienist removes plaque and tartar that brushing and flossing cannot eliminate, and the dentist conducts a thorough examination to catch problems early.
Who Needs More Than Two Cleanings Per Year?
Research consistently shows that certain patients benefit from more frequent professional cleanings. Dr. Oh evaluates each patient's unique circumstances and may recommend cleanings every three to four months if any of the following risk factors are present:
History of Gum Disease (Periodontal Disease)
If you have been diagnosed with gingivitis or periodontitis in the past, you are at elevated risk for recurrence. The bacteria that cause gum disease can recolonize quickly, and more frequent cleanings help keep them under control. Patients who have undergone scaling and root planing (deep cleaning) are typically placed on a three- to four-month maintenance schedule.
Diabetes
Diabetes and periodontal disease have a well-documented bidirectional relationship. High blood sugar impairs the body's ability to fight bacterial infections in the gums, and gum inflammation can make blood sugar harder to control. Diabetic patients often benefit from cleanings every three to four months.
Smoking and Tobacco Use
Tobacco use is one of the most significant risk factors for gum disease. Smoking reduces blood flow to the gums, impairs healing, and makes the mouth more hospitable to harmful bacteria. Smokers frequently need more aggressive preventive care to maintain gum health.
Pregnancy
Hormonal changes during pregnancy increase susceptibility to gingivitis, a condition sometimes called pregnancy gingivitis. The American Dental Association and the American College of Obstetricians and Gynecologists both support dental cleanings during pregnancy. Many practitioners recommend an additional cleaning during the second trimester.
Dry Mouth
Saliva plays a critical role in neutralizing acids and washing away food particles. Patients with chronic dry mouth — whether from medications, medical treatments, or conditions like Sjogren's syndrome — are at higher risk for cavities and gum disease and may need more frequent visits.
Weakened Immune System
Patients undergoing chemotherapy, organ transplant recipients on immunosuppressive drugs, and those with HIV/AIDS are more susceptible to oral infections. More frequent monitoring and cleaning help prevent complications.
Bottom line: The twice-a-year guideline is a minimum for healthy patients. If you have one or more risk factors, your dentist may recommend a personalized schedule of three to four cleanings per year. This is not upselling — it is evidence-based preventive medicine.
What Happens During a Professional Dental Cleaning?
Understanding what goes into a professional cleaning helps explain why it is so important and why brushing and flossing alone are not enough. Here is what to expect at a typical cleaning appointment at Westar Dental:
1. Examination and Assessment
Before the cleaning begins, the hygienist or dentist examines your mouth. This includes checking for signs of gum disease (measuring pocket depths around each tooth), looking for cavities, evaluating existing restorations, and screening for oral cancer. Digital X-rays may be taken periodically to reveal issues below the surface that are not visible during a visual examination.
2. Scaling (Tartar and Plaque Removal)
Using specialized instruments, the hygienist carefully removes plaque (soft bacterial film) and tartar (hardened calculus) from all tooth surfaces, including areas below the gumline. Tartar cannot be removed by a toothbrush or floss — only professional instruments can eliminate it. This is the most critical step in preventing gum disease progression.
3. Polishing
After scaling, a mildly abrasive polishing paste is applied with a rotating rubber cup to remove surface stains and smooth the tooth enamel. Smoother surfaces are more resistant to plaque accumulation between visits.
4. Flossing
The hygienist flosses between every tooth to remove any remaining debris and to check for areas of bleeding, which may indicate early gum inflammation.
5. Fluoride Treatment (When Recommended)
For patients at elevated cavity risk, a professional fluoride varnish may be applied. This concentrated fluoride strengthens enamel and provides protection against decay for several months.
6. Dentist Examination
Dr. Oh then performs a comprehensive examination, reviewing X-rays, evaluating gum health, checking the bite, and discussing any findings or treatment recommendations with you.

The Long-Term Benefits of Regular Dental Cleanings
Consistent preventive care is one of the best investments you can make in your overall health. The benefits extend well beyond a brighter smile:
- Early detection of cavities: Small cavities caught early can be treated with simple fillings rather than crowns, root canals, or extractions.
- Gum disease prevention: Professional cleaning is the most effective way to prevent gingivitis from progressing to periodontitis, which is the leading cause of tooth loss in adults.
- Oral cancer screening: Every cleaning appointment includes a visual and tactile screening for oral cancer. Early detection dramatically improves survival rates.
- Systemic health connections: Research has linked periodontal disease to increased risk of heart disease, stroke, diabetes complications, and adverse pregnancy outcomes. Keeping your gums healthy supports your whole body.
- Cost savings: Preventive care is dramatically less expensive than restorative treatment. A cleaning costs a fraction of what a root canal, crown, or implant costs. Patients who maintain regular cleanings spend significantly less on dental care over their lifetime.
- Fresh breath: Persistent bad breath (halitosis) is frequently caused by bacteria buildup that professional cleaning addresses at its source.
What If It Has Been a Long Time Since Your Last Cleaning?
If years have passed since your last dental visit, you are not alone, and there is no reason to feel embarrassed. Many patients delay care due to anxiety, cost concerns, or simply a busy schedule. At Westar Dental, our team treats every patient with compassion and without judgment, regardless of how long it has been.
If significant tartar has accumulated, your first visit back may involve a deeper cleaning called scaling and root planing, which is performed under local anesthesia for comfort. For patients with dental anxiety, Dr. Oh offer sedation options including nitrous oxide, oral sedation, and IV sedation to make the experience as comfortable as possible.
After the initial deep cleaning, you will be placed on a personalized maintenance schedule — typically every three to four months — until your gum health stabilizes. From there, you may be able to transition back to a standard six-month schedule.
