Most people should visit the dentist every six months for a routine checkup and professional cleaning. The Centers for Disease Control and Prevention recommends that every adult see a dentist at least once a year, but twice-yearly visits give your dental team the best chance to catch problems early and keep your teeth and gums healthy.
That twice-a-year standard is not a random number. It is based on how fast plaque builds up and hardens on your teeth, how quickly small cavities can grow into bigger ones, and how silently gum disease can progress without visible symptoms. According to the CDC's 2024 Behavioral Risk Factor Surveillance System survey, only 66% of U.S. adults visited a dentist in the past year. That means roughly one in three adults went at least 12 months without a checkup, leaving small problems to grow into painful and expensive ones. This article explains how often adults and children should visit, what happens during a checkup, who needs more frequent visits, what happens when you skip too many appointments, and how insurance typically covers preventive dental care.
How Often Should Adults Visit the Dentist for Checkups?
Adults should visit the dentist for checkups every six months as a general guideline. This recommendation comes from the American Dental Association, which advises scheduling routine exams and cleanings twice per year to maintain strong oral health. The CDC sets the minimum at once per year for all adults, but most dentists prefer the six-month interval because of how quickly dental problems develop.
Plaque, the sticky film of bacteria that forms on your teeth, begins accumulating within 20 minutes after eating. Within 24 to 48 hours, unremoved plaque hardens into tartar (also called calculus). Tartar cannot be removed by brushing or flossing at home. Only a dental professional using a scaler or ultrasonic instrument can remove it. Tartar buildup leads directly to tooth decay and gum disease. A six-month cleaning schedule keeps tartar from accumulating to levels that cause damage. The ADA reports that only 50% of Americans actually visit the dentist twice a year, which means half the population is falling behind on preventive dental services that could prevent costly problems later.
Can You Go to the Dentist Once a Year Instead of Twice?
Yes, you can go to the dentist once a year instead of twice, if you are at low risk for dental disease. Low-risk patients are adults with no history of cavities in the past three years, no signs of gum disease, no tobacco use, no chronic health conditions that affect oral health, and strong daily brushing and flossing habits.
Some research suggests that healthy adults with excellent oral hygiene can safely extend their recall interval to 12 or even 18 months without a significant increase in dental problems. However, the majority of adults have at least one risk factor that makes twice-yearly visits the safer choice. According to CDC data, nearly 46% of U.S. adults aged 30 and older show signs of gum disease, and 25% have untreated cavities. Your dentist can assess your individual risk and recommend the recall interval that fits your mouth.
How Often Should Children Visit the Dentist?
Children should visit the dentist every six months, starting by age one or when the first baby tooth comes through the gums, whichever happens first. The American Academy of Pediatric Dentistry and the ADA both recommend this early start because tooth decay can begin as soon as teeth appear in the mouth.
CDC data shows that 86.9% of children aged 2 to 17 had a dental visit in the past year, a higher rate than adults. That is encouraging, but the remaining 13% of children are missing out on checkups that catch cavities early and apply protective treatments like fluoride varnish and dental sealants. According to the CDC, dental sealants alone prevent 80% of cavities on the chewing surfaces of back teeth in children. Our pediatric dentistry team focuses on making visits comfortable and building good habits from the very first appointment.
Why Are Dental Checkups Important?
Dental checkups are important because they accomplish three things that brushing and flossing alone cannot: professional cleaning that removes tartar, early detection of dental and oral health problems, and screening for conditions you cannot see or feel on your own.
Even people who brush twice a day and floss daily miss plaque in hard-to-reach spots between the teeth and under the gumline. That missed plaque hardens into tartar, which traps bacteria against the tooth surface and gum tissue. Professional cleanings remove tartar before it causes cavities or gum inflammation. A 2020 study in the Global Burden of Disease series found that more than 90% of adults have had at least one cavity in their lifetime, which shows how common decay is even among people who try to take good care of their teeth.
Checkups also detect problems you cannot see. Small cavities, early-stage gum disease, hairline cracks, and the beginning stages of oral cancer often produce no pain or visible symptoms in their earliest stages. Your dentist can spot these warning signs during a routine exam and treat them before they grow into more serious, more expensive problems. Research from the National Institute of Dental and Craniofacial Research shows that untreated dental disease costs the U.S. economy more than $45 billion annually in lost productivity, much of it preventable through regular preventive care.
What Do Dentists Check for During a Cleaning?
Dentists check for cavities, gum disease, oral cancer, bite alignment issues, signs of teeth grinding (bruxism), and any changes in your mouth since your last visit during a cleaning. The exam portion of your visit is just as important as the cleaning itself.
Your dentist or hygienist will measure the depth of the gum pockets around each tooth using a periodontal probe. Healthy pockets measure 1 to 3 millimeters deep. Pockets measuring 4 millimeters or deeper indicate the beginning of gum disease. The dentist also examines your tongue, the roof of your mouth, your throat, your neck, and your jaw joints for any lumps, swelling, discoloration, or other abnormalities. This oral cancer screening is a standard part of every routine checkup and takes only a few minutes, but it can catch cancer at an early, highly treatable stage.
What Happens During a Routine Dental Checkup?
A routine dental checkup follows a predictable sequence that covers both cleaning and examination. Knowing what to expect can help reduce anxiety, especially if it has been a while since your last visit. Here is the typical order of a dental checkup from start to finish:
The dental team checks you in, updates your medical history, and asks about any changes in medications, health conditions, or symptoms since your last visit.
If X-rays are due (typically once a year for bitewing X-rays), the hygienist takes them before the cleaning begins so the dentist can review them during the exam.
The hygienist performs the professional cleaning, which includes scaling (removing plaque and tartar from above and below the gumline), polishing the teeth with a gritty paste to remove surface stains, and flossing between each tooth.
The dentist performs a thorough examination of your teeth, gums, tongue, and soft tissues, using the X-rays, a small mirror, and a probe to check every surface.
The dentist discusses any findings with you, recommends treatment if needed, and answers your questions.
The front desk schedules your next checkup, usually six months out, and reviews any insurance benefits or billing.
The entire process is designed to be efficient, thorough, and comfortable. We walk every patient through each step so there are no surprises.
How Long Does a Dental Checkup Take?
A dental checkup takes 45 minutes to one hour for most patients. The cleaning portion accounts for about 30 to 40 minutes, and the dentist's examination adds another 10 to 15 minutes. If X-rays are needed, add approximately 5 to 10 minutes at the beginning of the appointment.
Patients who have not visited the dentist in over a year may need a longer appointment because more tartar has accumulated and the dentist may need additional X-rays or a more detailed exam. Patients with gum disease who require deep cleaning (scaling and root planing) typically need a separate, longer appointment that focuses specifically on treating the gum tissue below the gumline.
Who Needs to See the Dentist More Than Twice a Year?
Certain patients need to see the dentist more than twice a year because their health conditions, habits, or oral health history put them at higher risk for dental disease. For these patients, a checkup every three to four months gives the dental team enough time to monitor and manage developing problems before they advance.
The table below shows common risk categories with recommended visit frequency and the reason behind each.

Your dentist determines your risk category based on your clinical exam, your medical history, and your oral hygiene habits at home. The recall interval is not fixed for life. As your health improves or changes, the frequency can adjust. A patient who completes treatment for gum disease and maintains excellent home care, for example, may eventually move back to a standard six-month schedule.
What Is the Most Serious Dental Disease?
The most serious dental disease is periodontal (gum) disease, which affects the gum tissue and the bone that supports your teeth. Gum disease is the leading cause of tooth loss in adults and has been linked to increased risk of heart disease, stroke, diabetes complications, and respiratory infections. CDC data shows that nearly 46% of U.S. adults aged 30 and older have some form of periodontal disease, making it one of the most common chronic conditions in the country.
Gum disease develops silently. The early stage, gingivitis, causes red, swollen gums that bleed during brushing or flossing. Many people dismiss this bleeding as normal, but it is a warning sign. Without treatment, gingivitis advances into periodontitis, where the gum tissue pulls away from the teeth and the underlying bone begins to break down. Regular dental checkups catch gum disease at the gingivitis stage, when it is completely reversible with professional cleaning and improved home care.
What Happens if You Skip Dental Visits for Years?
Skipping dental visits for years allows small, painless problems to grow into serious, painful, and expensive ones. Cavities that a dentist could have filled in one visit become deep infections that need root canals or extractions. Gum disease that a cleaning could have reversed at the gingivitis stage advances to periodontitis and causes permanent bone loss.
The financial impact of skipping visits compounds over time. A simple filling might cost a fraction of what a root canal, crown, or extraction with replacement costs. The American Dental Association reports that 40% of U.S. adults only visit the dentist when they have a problem, which means they are paying for treatment of conditions that preventive visits could have avoided.
Untreated toothaches and infections that start as small cavities can escalate quickly into situations that require urgent same-day care. Tartar buildup, deepening gum pockets, and weakening enamel all progress silently between missed appointments.
Here are common warning signs that you have waited too long between dental visits:
Gums that bleed when you brush or floss, even lightly
Persistent bad breath that does not improve with brushing
Visible tartar buildup (a hard yellowish or brown deposit along the gumline)
Tooth sensitivity to hot, cold, or sweet foods that was not there before
A dull ache or sharp pain in a tooth that comes and goes
Dark spots or discoloration on any tooth surface
Any of these signs warrants a call to your dentist. The longer you wait after noticing symptoms, the more likely a small problem will turn into a dental emergency that needs immediate treatment.
At What Age Do People Lose Their Teeth?
People typically begin losing permanent teeth between the ages of 50 and 64, though tooth loss can happen at any age when dental disease goes untreated. According to the National Institute of Dental and Craniofacial Research, adults aged 20 to 64 have an average of 24.92 remaining teeth out of a full set of 32, and the number decreases steadily with age. Among adults 65 and older, approximately 25% have lost all of their natural teeth.
Tooth loss is not an inevitable part of aging. It is the result of decades of accumulated damage from cavities, gum disease, and trauma that regular dental checkups are specifically designed to prevent. When a tooth is lost, replacement options like dentures, bridges, or implants restore function, but nothing matches the strength and feel of a natural tooth. Keeping your natural teeth through consistent preventive care is always the best outcome.
Is It Too Late to Go to the Dentist if You Haven't Been in Years?
No, it is never too late to go to the dentist, even if you have not been in years. Dentists see patients in this situation regularly, and no one will judge you for the gap. The first visit after a long absence typically involves a comprehensive exam, a full set of X-rays, and a thorough cleaning, which may take longer than a standard appointment.
Your dentist will assess everything, build a clear picture of your current oral health, and create a treatment plan that addresses the most urgent needs first. Some patients need nothing more than a deep cleaning to get back on track. Others may need fillings, gum treatment, or other restorative work. In Cinnaminson, we see patients at every stage of their dental journey, and we work with you to build a path forward that fits your schedule and your budget. The most important step is making that first call, because waiting for pain to force you in always leads to more treatment than coming in proactively.
Does Dental Insurance Cover Two Cleanings a Year?
Yes, most dental insurance plans cover two preventive cleanings and exams per year, typically at 100% with no out-of-pocket cost to the patient. Preventive visits, which include the cleaning, the exam, and routine X-rays, are the most fully covered benefit in nearly every PPO dental plan because insurance companies know that prevention costs far less than treatment.
Data from the National Center for Health Statistics shows that adults with dental coverage are significantly more likely to visit the dentist: 69.6% of covered adults had a dental visit in the past year, compared to 56.4% of adults without coverage. Even if you do not have insurance, many dental offices offer in-house savings plans or payment options that make routine dental care affordable.
Our office accepts most PPO plans and also offers an in-office dental plan for patients without insurance. You can check our insurance and payment options page for full details on what is covered and how to get started.
Frequently Asked Questions
How Often Do You Really Need a Dental Checkup?
You really need a dental checkup at least once a year, per CDC guidelines, and ideally every six months, per the ADA recommendation. The exact frequency depends on your individual risk for cavities, gum disease, and other oral health conditions. Your dentist will recommend the schedule that gives you the best protection based on your clinical exam and medical history.
Do Dentists Recommend Cleanings Every 3 Months or 6 Months?
Dentists recommend cleanings every 6 months for most patients and every 3 to 4 months for higher-risk patients. High-risk categories include people with active gum disease, diabetes, a smoking habit, or a weakened immune system. The shorter interval gives the dental team more opportunities to remove tartar and monitor disease progression before it causes permanent damage.
Can Poor Dental Health Affect Your Overall Health?
Yes, poor dental health can affect your overall health. Research has linked untreated gum disease to increased risk of heart disease, stroke, diabetes complications, respiratory infections, and pregnancy complications. Bacteria from infected gums can enter the bloodstream and trigger inflammation in other parts of the body. The World Health Organization reports that over 3.5 billion people worldwide suffer from oral diseases, making them the most common chronic conditions globally.
Should You Still See a Dentist if Your Teeth Feel Fine?
Yes, you should still see a dentist if your teeth feel fine, because many dental problems develop without pain or visible symptoms in their early stages. Cavities, gum disease, and oral cancer can all progress silently for months or even years before you notice anything wrong. A routine checkup catches these problems early, when treatment is simpler, less invasive, and less expensive.
What Is the Best Age to Start Taking a Child to the Dentist?
The best age to start taking a child to the dentist is by age one or when the first baby tooth appears, whichever comes first. Early visits allow the dentist to check for proper development, apply fluoride varnish to protect new teeth, and educate parents on preventing tooth loss through good habits that start in childhood.
How Do You Find a Dentist if You Have Not Been in a Long Time?
You find a dentist after a long absence by calling offices in your area and asking whether they accept new patients who have not visited in several years. A good dental office will schedule a comprehensive exam without judgment and work with you on a step-by-step plan to restore your oral health. Many practices, including ours, prioritize making patients in this situation feel comfortable and supported from the very first call.
The Takeaway
Visiting the dentist every six months is one of the simplest and most effective things you can do for your teeth, your gums, and your overall health. Regular checkups catch small problems before they turn into big ones, keep tartar under control, screen for oral cancer, and give your dentist the ongoing relationship with your mouth that leads to better, more personalized care over time.
