During a dental exam, your dentist reviews your medical and dental history, takes X-rays when needed, examines your teeth and gums for signs of decay and disease, screens for oral cancer, and works with a hygienist to professionally clean your teeth. According to the CDC, only about 65% of adults aged 18 and older had a dental exam or cleaning in the past year. That means roughly one in three adults is skipping this basic preventive care. Below, we walk through every step of a dental exam so you know exactly what to expect and why each part matters.

What Is Done in a Dental Examination?

In a dental examination, the dentist performs a thorough evaluation of your teeth, gums, jaw, tongue, throat, and surrounding soft tissues. The goal is to detect problems early, when they are small, easy to treat, and far less expensive to fix.

Here in Littleton, Colorado, we follow the same process at every visit. It starts the moment you sit down in the chair. We review your medical history to check for any changes in medications, health conditions, or concerns since your last visit. This step matters more than most people realize. Conditions like diabetes, heart disease, and autoimmune disorders can directly affect your oral health. According to the CDC, people with diabetes are twice as likely to develop gum disease. We need to know about those conditions to tailor your care properly.

After the history review, the exam itself covers several key areas. We check every tooth for signs of decay, cracks, and wear. We evaluate your gums for inflammation, recession, and early signs of periodontal disease. We examine your bite and jaw alignment for signs of grinding or TMD. We inspect the soft tissues of your mouth, including your tongue, cheeks, and the floor of your mouth, for anything unusual. And we take X-rays when needed to see what is happening below the surface.

According to the ADA, only about 50% of Americans visit the dentist twice a year as recommended. The other half are missing out on the early detection that prevents small issues from turning into big, costly problems.

Step-by-Step: What to Expect at Your Dental Exam

Knowing what happens at each stage can take the mystery out of the visit, especially if it has been a while since your last one.

Medical and dental history review. We start by asking about any changes to your health. New medications, recent surgeries, allergies, and chronic conditions all influence how we approach your care. If you are a new patient, this step is more detailed. We want to get to know you, hear your concerns, and understand your full health picture before any work is done.

Digital X-rays. X-rays reveal what the eye cannot see, including cavities between teeth, bone loss around roots, infections below the gum line, and impacted teeth. We take full-mouth X-rays for new patients and update them once a year for existing patients. The radiation exposure from modern digital X-rays is extremely low. According to MedlinePlus (National Library of Medicine), the dose is very small and the images are invaluable for catching hidden problems early.

Visual and clinical examination. The dentist uses a mirror, explorer, and other instruments to inspect every tooth surface, check existing fillings and restorations for wear, and evaluate gum health. We measure the depth of the pockets between your gums and teeth, which is one of the best indicators of gum disease. Healthy gums typically have pockets of 1 to 3 millimeters. According to the CDC, nearly 46% of adults aged 30 and older show signs of gum disease, so this measurement is a critical part of every exam.

Oral cancer screening. This is a part of the exam many patients do not even realize is happening. We examine the soft tissues of your mouth, head, and neck for any unusual lumps, sores, or discoloration. At our Littleton office, we also use the Velscope oral cancer screening device, which uses a specialized light to detect abnormal tissue that may not be visible to the naked eye. According to the American Cancer Society, oral cancers are most commonly diagnosed in adults over 55, making routine screening essential.

Professional cleaning. After the exam, the hygienist performs a thorough dental cleaning. This includes scaling to remove plaque and tartar from your teeth and below the gum line, polishing to smooth the enamel and remove surface stains, and flossing between each tooth. A fluoride treatment may be applied for added protection against decay.

Discussion of findings. The dentist reviews everything with you: what looks good, what needs attention, and what the recommended next steps are. If treatment is needed, we discuss the options and develop a plan together. We believe the most successful outcomes happen when patients are fully involved in the decision.

How Long Does a Dental Exam Take?

A dental exam typically takes 45 to 60 minutes when combined with a professional cleaning. For new patients, the first visit may take 60 to 90 minutes because it includes a more detailed history review, full-mouth X-rays, and a comprehensive evaluation of your overall oral health.

The time is well spent. According to a study published in the Journal of Public Health Dentistry, adults who receive regular preventive dental care have significantly lower overall dental costs compared to those who skip preventive visits. Those who skip also have higher rates of emergency department visits for dental pain, oral surgery, and opioid prescriptions. A one-hour exam every six months is a small investment that prevents much bigger problems down the line.

At our Littleton practice, we offer early morning appointments starting at 7:00 AM and evening hours until 7:00 PM on Tuesday through Thursday. We know schedules are tight, and we work to make it as easy as possible for families in the South Denver area to stay on track with their exams.

Why Does a Dentist Feel Under the Jaw?

A dentist feels under the jaw to check for swollen lymph nodes, unusual lumps, or tenderness that could indicate an infection, inflammation, or something more serious like oral cancer.

The lymph nodes under the jaw and along the neck are part of your immune system. When they are swollen or tender, it often means your body is fighting an infection somewhere nearby. During a dental exam, checking these areas helps the dentist detect problems that go beyond just the teeth and gums. According to the American Academy of Family Physicians, oral signs are frequently the first clue to underlying systemic conditions, including infections, autoimmune disorders, and certain cancers.

This is one of those steps that takes just a few seconds but can catch something significant early. We include it as part of every exam at our Littleton office because dentistry is about much more than just teeth. It is about your overall health.

What Does 7 Mean at the Dentist?

When you hear the dentist call out the number 7 during an exam, it refers to the depth of a gum pocket in millimeters. A measurement of 7 millimeters means there is significant space between the gum and the tooth, which is a strong indicator of advanced periodontal (gum) disease.

Here is how the numbers break down. Pockets of 1 to 3 millimeters are healthy. Pockets of 4 to 5 millimeters suggest early to moderate gum disease. Pockets of 6 millimeters or more indicate advanced disease that needs prompt treatment. A reading of 7 means bone loss has likely occurred around the tooth, and without treatment, the tooth is at risk of becoming loose or needing extraction.

During your exam, you may hear the dentist or hygienist calling out a series of numbers. Those are the pocket measurements being taken around each tooth, six measurements per tooth. It is one of the most important parts of the exam. According to the CDC, nearly 46% of adults over 30 have some form of gum disease, and many do not know it until these measurements reveal it. If you hear higher numbers, it does not mean you are in trouble. It means we caught it, and we can treat it. Patients with deeper pockets may need scaling and root planing (a deep cleaning) to get the disease under control.

What Can a Dental Exam Detect Beyond Cavities?

A dental exam can detect far more than just cavities. It can reveal gum disease, oral cancer, cracked or worn teeth, failing restorations, bite problems, teeth grinding (bruxism), TMJ disorders, bone loss, and even signs of systemic conditions like diabetes and nutritional deficiencies.

According to the Mayo Clinic, the mouth can be an entry point for infections that affect the rest of the body, and oral health problems have been linked to cardiovascular disease, diabetes complications, and pregnancy issues. A routine dental exam is one of the few medical appointments that screens for such a wide range of conditions in a single visit.

We take this seriously at our Littleton practice. Every exam includes an evaluation for TMD and bite issues, a check for signs of grinding that may require an occlusal guard, and a thorough look at existing dental work to make sure old fillings and restorations are still holding up. If a filling is breaking down, we can replace it before it leads to a larger cavity or a crack that needs a crown.

Frequently Asked Questions

What to Bring to the First Dentist Appointment?

To your first dentist appointment, bring a valid photo ID, your dental insurance card (if applicable), a list of current medications, and any previous dental records or X-rays if you have them. If you do not have previous records, that is perfectly fine. We will take new X-rays and do a complete assessment. You can also download and fill out our patient forms ahead of time to speed up the check-in process at our Littleton office.

How Often Should I Get a Dental Exam?

Most adults should get a dental exam every six months. This is the standard recommendation from the ADA. If you have gum disease, diabetes, or a high cavity rate, we may recommend exams every three to four months. According to the CDC, only about 65% of adults had a dental visit in the past year. Staying on schedule is the single most effective way to catch problems early and avoid expensive treatments later.

Are Dental Exams Painful?

Dental exams are not painful. The exam itself involves a visual inspection, gentle probing, and pocket measurements, none of which should cause pain. The cleaning portion may cause mild sensitivity if there is significant tartar buildup, but it should not be painful. For patients in Littleton who feel anxious, we offer no-fear dentistry with amenities like music headphones, flat-screen TVs, and sedation options to keep you comfortable.

What Can a Dentist Do for Nerve Damage?

A dentist can treat nerve damage inside a tooth with root canal therapy. This procedure removes the damaged or infected nerve tissue, cleans and seals the inside of the tooth, and saves the tooth structure. After a root canal, the tooth is usually protected with a crown. If the nerve damage is too severe and the tooth cannot be saved, an extraction may be necessary, followed by replacement options like a dental implant.

Does Insurance Cover Dental Exams?

Yes, most dental insurance plans cover two preventive exams and cleanings per year. We accept all insurance that allows you to choose your own dentist. If you do not have insurance, we offer our Dental Savings Network in Littleton with no yearly maximums, no deductibles, and no claim forms. We also accept CareCredit for flexible financing.

Do Kids Need a Different Kind of Dental Exam?

Kids go through the same basic exam process, but with extra focus on development, eruption patterns, and prevention. We recommend children see a dentist by age one, per ADA guidelines. Our pediatric dentistry services in Littleton include exams, cleanings, fluoride treatments, and sealants, all delivered in a way that makes kids feel safe and comfortable from their very first visit.
