Which dental exam do you need?

Reviewed by Dr. Samar Fadavi, DDS

Short answer: Most people need one of four exam types: a complete exam when you are new to a practice or have not been seen in years, a recall exam at regular check-ups, an emergency exam for a specific problem, and a specific exam to recheck one area. Your dentist recommends the type and timing based on your mouth and health.

What type of dental exam do you need?

“Dental exam” sounds like one thing, but dentists use several kinds of exam for different situations. A first visit at a new office looks very different from a six-month check-up, and both differ from a visit for a sudden toothache. Knowing the difference helps you understand what will happen in the chair, what to bring, and how your insurance or the Canadian Dental Care Plan may treat each visit.

Why the type of exam matters

Each exam type has a different depth and purpose. Choosing the right one means you get a thorough look when you need it, without repeating a full assessment at every visit. It also matters for coverage, because insurance plans often limit how often each type of exam is covered.

Complete exam

Also called a comprehensive exam, this is the most thorough. It is usually done when you are new to a dental office, when it has been several years since your last visit, or periodically as your dentist recommends. It includes a full medical and dental history, a check of every tooth and existing filling or crown, gum measurements around each tooth, a look at your bite and jaw joints, an oral cancer screening of the tongue, cheeks, palate, lips and throat, and a check of the lymph nodes in your neck. X-rays are taken as needed to see between teeth, around roots and in the jawbone.

Recall exam

This is the regular check-up exam, often booked with a cleaning. The dentist updates your health history, looks for changes since last time, checks gums and existing dental work, and repeats the oral cancer screening. Small x-rays of the back teeth, called bitewings, are taken at intervals based on your risk of decay.

Emergency exam

Also called a limited exam, this focuses on one problem: pain, swelling, a broken tooth, a lost filling or an injury. The dentist examines the area, usually takes an x-ray of the tooth involved and explains what is wrong and what can be done. The goal is relief and a clear plan. You do not need to be an existing patient for this kind of visit.

Specific exam

This rechecks a known area, such as healing after an extraction, a tooth the dentist has been watching, or gum pockets after treatment.

Children’s exams

Exams for children also check how teeth are coming in, how the jaws are growing, and habits such as thumb sucking. They are a chance to discuss brushing, diet, fluoride and sealants with parents.

Treatment consultations

Before implants, wisdom tooth removal, complex root canal treatment or orthodontics, the dentist may need more detailed imaging. Our office offers CBCT 3D imaging, which shows bone, nerves and roots in three dimensions when a standard x-ray is not enough.

The x-rays an exam may include

• Bitewings. Small images of the back teeth that show decay between teeth and the bone level around them. These are the most common x-rays at recall exams.
• Periapical x-rays. Images of one or two whole teeth from crown to root tip. They show infections at the root, cracks and bone loss, and are often taken at emergency exams.
• Panoramic x-ray. One wide image of both jaws, the teeth, the jaw joints and the sinuses. It is useful for wisdom teeth, children’s developing teeth and an overall picture.
• CBCT 3D imaging. A three-dimensional scan used for specific questions such as implant planning, complex root canals or wisdom teeth close to a nerve.

Digital dental x-rays use a small amount of radiation, and they are taken only when the information will change your care.

What the dentist looks for in your gums

Healthy gums are pink, firm and do not bleed when gently probed. The dentist looks for redness, swelling, bleeding, recession, tartar below the gum line and teeth that have become loose. These signs show whether you have gingivitis, which is reversible, or periodontitis, which damages the bone that holds teeth in place and needs ongoing care.

Oral cancer screening in more detail

During a screening, the dentist looks at the lips, the inside of the cheeks, the gums, the tongue (including its sides and underside), the floor of the mouth, the roof of the mouth and the back of the throat. They gently feel the tongue, the floor of the mouth and the neck for lumps. Most findings turn out to be harmless, such as a bitten cheek or an irritated spot from a sharp tooth. Anything that does not heal within about two weeks is rechecked, and if it still looks unusual the dentist arranges a referral for further assessment. Risk rises with tobacco use, heavy drinking, sun exposure on the lips and age, but screening is for everyone.

Exams when you have a health condition

Diabetes, heart disease, cancer treatment, pregnancy and many medications affect the mouth. If you have a condition like these, your exam includes questions about it, and the dentist may suggest more frequent visits or extra preventive care such as fluoride.

What happens at a dental exam, step by step

1. Before the visit, gather your health information. Make a list of medications, allergies, recent surgeries and any conditions such as diabetes or heart disease.
2. Arrange your records. If you are new, tell us the name of your previous dentist. With your permission we can request recent x-rays, which may avoid taking new ones.
3. Write down your concerns. Sensitivity, a sore spot, bleeding gums, a cosmetic question: noting them helps you remember in the chair.
4. History review. The visit starts with a conversation about your health, medications and any problems.
5. The exam itself. The dentist checks teeth, gums, bite and soft tissues. For a complete exam, gum pocket depths are measured and recorded around every tooth.
6. X-rays if needed. The type and number depend on the exam and your risk. Not every visit needs them.
7. Your plan. You hear what was found, in plain language, with problems sorted into urgent, soon and can wait. You can ask for a written treatment plan and an estimate.
8. Your next visit. The dentist suggests a recall interval. For some people that is every six months; for others it is more or less often.

What to avoid

• Waiting until something hurts. Decay and gum disease often cause no pain until they are advanced. Regular exams catch them while treatment is simpler.
• Assuming a cleaning is the same as an exam. A cleaning removes plaque and tartar. The exam is the dentist’s assessment of your whole mouth.
• Refusing all x-rays without discussing it. If you have concerns, ask why an x-ray is recommended. Decay between teeth and infections at the root tip often cannot be seen any other way.
• Leaving out medications or conditions. They affect what is safe and what we look for.
• Ignoring a sore that will not heal. Any mouth sore lasting more than two weeks should be checked, even between regular exams.

How often each type of exam is usually needed

There is no single schedule that fits everyone. A recall exam is commonly booked every six months, but people with healthy gums and few past cavities may be fine with a longer interval, while people with gum disease, diabetes, dry mouth, braces or a history of frequent decay often benefit from visits every three to four months. A complete exam is usually done when you are new to an office and then every few years, or when your health changes. Emergency or limited exams happen whenever a specific problem appears. Your dentist will suggest an interval based on your own risk and explain why.

X-rays follow the same idea. They are taken when the dentist needs information that cannot be seen by eye, not on a fixed calendar, and the frequency depends on your age, history and current findings.

How to prepare for your exam

• Bring a list of medications, allergies and recent health changes, including surgeries or new diagnoses.
• Bring your insurance details or CDCP information so billing can be set up before treatment.
• Write down any symptoms: sensitivity, bleeding gums, jaw clicking, a rough edge, a bad taste.
• If you have old X-rays from another office, ask for them to be sent ahead of time.
• Brush and floss as usual; there is no need to do anything special.
• If you feel nervous, say so when you book, so the team can plan extra time.

Coming prepared helps the dentist choose the right type of exam and makes the most of your appointment.

If you are not sure which type of exam you need, simply describe your situation when you call. The front desk will book the right length of appointment, and the dentist will confirm the type of exam once you are in the chair.

When to see a dentist

• You are new to the area or it has been a while. Book a complete exam. Our new patients page explains the first visit.
• You are due for a check-up. Our check-ups and cleanings page covers routine care for the whole family.
• Something hurts, is swollen or broke. Book an emergency exam. See our emergency dentist page for same-day visits.
• You noticed a change. A lump, a white or red patch, a loose tooth or gums that bleed every day all deserve a look.

Questions about dental exams

How often do I need a check-up?

It depends on your risk. Many people do well with a check-up every six months. People with gum disease, frequent decay or certain health conditions may need visits more often, and some low-risk adults can go longer. Your dentist recommends an interval for you.

Do I need x-rays at every visit?

No. X-rays are taken when they will answer a question, at intervals based on your risk and history.

What is an oral cancer screening?

It is a look and a gentle feel of the tongue, cheeks, floor of the mouth, palate, lips, throat and neck for lumps, patches or sores. It takes a few minutes and is part of complete and recall exams.

What is gum charting?

The dentist uses a thin, marked probe to measure the space between each tooth and the gum. Healthy spaces are shallow. Deeper pockets can mean gum disease.

Can I come in for just one problem?

Yes. An emergency exam focuses on that problem. We can book a complete exam later if you want one.

Will my plan cover the exam?

Most dental plans cover exams, often with limits on how often each type is covered. We bill insurers directly and accept the Canadian Dental Care Plan. Check your plan details or ask us to help.

Why does a complete exam take longer?

Because it looks at everything: every tooth surface, every gum pocket, your bite, jaw joints and soft tissues, plus a full health history and often a set of x-rays. It becomes the baseline we compare against at future visits.

Do children need a different kind of exam?

Children have the same exam types, adapted to their age. Our children’s dentistry page explains what happens at each stage.

What should I bring to my first visit?

Bring your medication list, your insurance or CDCP details, any recent dental records you have, and a list of questions. If you have a denture, night guard or retainer, bring that too.

How long does each exam take?

A complete exam with x-rays takes longer than a recall exam, and an emergency exam is usually the shortest. When you book, we let you know how much time to set aside.

Can I get a copy of my x-rays?

Yes. Your records belong to your care. Ask us and we can send them to you or to another dental office with your written permission.
