Dental Health Blog

It's one of the most common questions we hear at Gentle Family Dentistry in Hampton, NH: "Do I really need to come in every six months?" The answer is almost always yes — and the research from the American Dental Association (ADA) backs that up. But the full picture is a little more nuanced, and understanding it can help you take better control of your long-term oral health.

Whether you're a patient in Hampton, Portsmouth, Exeter, Dover, or anywhere along the NH Seacoast, here's what the ADA actually recommends — and why it matters more than most people realize.

The ADA's Official Recommendation

The American Dental Association recommends that patients visit a dentist regularly — and for most adults, "regularly" means every six months. This means two professional cleanings and two comprehensive exams per year.

However, the ADA also acknowledges that recall intervals should be individualized based on each patient's disease risk. Not everyone fits neatly into a once-every-six-months schedule, and that's by design.

Why Twice a Year Is the Standard Starting Point

The six-month interval isn't arbitrary. It's based on how quickly bacterial plaque can mineralize into tartar (also called calculus) — and tartar cannot be removed by brushing or flossing alone. Only a dental hygienist with professional instruments can remove it.

Here's what happens when tartar builds up unchecked:

• It irritates the gums, leading to gingivitis (the earliest stage of gum disease)
• If left untreated, gingivitis advances to periodontitis — a serious infection that destroys the bone and tissue holding your teeth in place
• According to CDC data cited by the ADA, an estimated 47.2% of adults over age 30 in the United States have some form of periodontal disease — roughly 64.7 million Americans — and many don't know it
• Among adults 65 and older, that figure climbs even higher

Regular cleanings break this cycle before it starts. And cavities are far more common than most people realize — 91% of U.S. adults aged 20–64 have had at least one cavity in a permanent tooth. A professional cleaning every six months keeps tartar levels low, lets your hygienist catch early signs of gum disease, and gives Dr. Li the opportunity to detect cavities and oral cancer at their most treatable stages.

When You May Need to Come In More Often

Six months is the minimum for most healthy adults. But certain conditions increase your risk of dental problems — and for those patients, Dr. Li typically recommends cleanings every 3–4 months:

• Active gum disease (periodontitis): More frequent cleanings, called "periodontal maintenance," are a cornerstone of keeping gum disease from progressing
• Tobacco use: Smoking and chewing tobacco dramatically increase the risk of gum disease, oral cancer, and tooth loss
• Diabetes: There is a well-documented two-way relationship between diabetes and gum disease — each makes the other harder to control
• Dry mouth (xerostomia): Saliva is your mouth's natural defense against bacteria. Patients on certain medications or those with systemic conditions that cause dry mouth are at significantly higher cavity risk
• Pregnancy: Hormonal changes during pregnancy increase susceptibility to gingivitis, making dental visits especially important
• A history of frequent cavities: Some patients are simply more cavity-prone due to genetics, diet, or salivary chemistry
• Orthodontic appliances: Braces and aligners create more surfaces where plaque can hide

What About Children?

The American Academy of Pediatric Dentistry (AAPD) recommends that a child's first dental visit happen by age 1 — or as soon as the first tooth erupts, whichever comes first. This might seem early, but early visits accomplish several things:

• Establish a "dental home" so your child sees the dentist as a safe, familiar place
• Allow the dentist to monitor jaw and tooth development from the very beginning
• Let parents ask questions about brushing, diet, and pacifier use
• Create positive associations that last a lifetime

After that first visit, most children benefit from the same six-month schedule as adults. At Gentle Family Dentistry, we see patients of all ages — from toddlers through seniors — and we love making dental visits a positive experience for the whole family.

The Daily Habits That Make Every Visit Count More

Your dental visit is only two hours out of your entire year. What you do the other 8,758 hours matters enormously. The ADA recommends these daily habits to keep your mouth as healthy as possible between visits:

• Brush twice a day with a fluoride toothpaste for at least two minutes each session — roughly 30 seconds per quadrant of your mouth
• Clean between your teeth daily using floss, an interdental brush, or an oral irrigator. Adults who regularly floss are significantly less likely to develop periodontitis
• Limit sugary beverages and snacks — multiple systematic reviews have confirmed the link between sugar intake and cavity development
• Use a soft-bristle toothbrush and replace it every three to four months (or after illness)
• Don't smoke or use tobacco — tobacco use is one of the strongest risk factors for gum disease, oral cancer, and tooth loss

What Happens at a Dental Checkup?

A lot more than most people expect. At Gentle Family Dentistry in Hampton, NH, a routine visit typically includes:

• Professional cleaning (prophylaxis): Removal of plaque and tartar from all tooth surfaces and below the gumline
• Periodontal (gum) assessment: Measuring pocket depths around each tooth to detect early gum disease
• Digital X-rays (as needed, typically once a year): Reveal cavities between teeth, bone loss, and issues not visible on the surface
• Comprehensive exam by Dr. Li: Checking for cavities, evaluating existing restorations, examining the jaw joints (TMJ), and screening for oral cancer
• Oral cancer screening: A quick visual check of the tongue, cheeks, throat, and lymph nodes — takes about 60 seconds and can be life-saving
• Personalized treatment recommendations: If Dr. Li finds something that needs attention, you'll leave with a clear picture of your options and costs

The Cost of Skipping

We understand life gets busy. But the cost of not going to the dentist is almost always higher than the cost of going. A cavity caught at a small, early stage is a simple filling. Left untreated, the same cavity can grow to require a crown — and if it reaches the nerve, a root canal followed by a crown.

Gum disease, similarly, is far easier (and less expensive) to treat in its early stages (gingivitis) than in its advanced stages, where bone grafting and surgical procedures may be required.
