An intraoral camera is a small, pen-sized dental camera with a light at its tip that shows magnified pictures of your teeth and gums on a screen while you watch. It helps your dentist explain and record what can be seen on the surface. It does not use radiation, and it does not replace an exam or dental X-rays when those are needed.
Key Takeaways
- An intraoral camera is a handheld wand with a lens and built-in light that sends close-up, magnified images of the mouth to a chairside monitor in real time.
- Intraoral camera images show surfaces you can see with light: enamel, fillings, crown edges, gums and other soft tissues. They cannot show roots, bone or decay hidden between teeth.
- The camera does not use X-rays or any ionizing radiation, so it can be used whenever a picture would help a conversation.
- Saved intraoral photos can serve as a baseline so your dentist can compare a watched area at later visits.
- A photo is one piece of information. Diagnosis still depends on your dentist's exam, your history and, when indicated, radiographs or other tests.
What is an intraoral camera?
An intraoral camera is a small digital camera designed to fit inside the mouth. Most look like a thick pen or a slim wand. At the tip there is a tiny lens and a light source, and the handle connects to a computer or monitor so the image appears on a screen beside the dental chair.
The purpose of an intraoral camera is simple: to let the dental team and the patient see the same thing at the same time. A dental mirror shows the dentist a small, reversed view that you cannot see from the chair. The camera turns that view into a large, well-lit picture on a screen.
Intraoral cameras are not new. A 2019 review in Clinical, Cosmetic and Investigational Dentistry notes that the first dental intraoral camera appeared in 1987, and that modern systems use LED lighting and digital sensors that produce clearer images than early models. Exact features, such as resolution, capture buttons, magnification levels and wired or wireless design, vary by manufacturer. This article describes the general idea rather than any single model.
For how the camera fits into visits at our practice, see Landmark Dental Care's intraoral camera page.
How does an intraoral camera work?
An intraoral camera works much like the camera in a phone, only smaller and built for close-up work in a wet, dark space. Light from the tip illuminates the area, the lens focuses on a tooth or a patch of gum tissue, and a sensor turns the reflected light into a digital image that appears on the monitor almost instantly.
The process at the chair usually goes like this:
- Positioning. The dentist or hygienist places the tip close to the area of interest. Because the wand is slim, it can reach the back molars and the tongue side of teeth, which are hard to show with a hand mirror.
- Lighting and drying. The built-in light removes shadows. The clinician may dry the tooth with a puff of air or move the cheek aside, because saliva and fogging can blur the picture.
- Live view. You see a live, magnified image on the screen as the camera moves.
- Capture and discussion. When the clinician finds a useful view, they freeze it, enlarge it and walk you through it. Only images that document a finding or set a baseline are usually kept.
Each image takes only a moment. The camera is used for looking, not for cleaning, drilling or scraping, so the wand itself rarely causes discomfort.
Does an intraoral camera use radiation?
No. An intraoral camera records ordinary visible light reflected from the surface of the tooth. Dental X-rays use ionizing radiation to pass through tissue and show what is inside, which is why the Canadian Dental Association says radiographs should be prescribed only when a clinical exam shows they are justified. The camera carries no radiation exposure, so it can be used freely when a picture helps.
What can intraoral camera images show?
Intraoral camera images show what can be seen with light on the surface of the mouth. Within that limit, they can be very detailed. The common uses below appear both in how Landmark Dental Care describes its camera and in the published literature on intraoral cameras.
Teeth and enamel
An intraoral camera can show visible decay on a chewing surface, dark or chalky spots, worn edges from grinding, and chips. It can also show fine crack lines on the crown of a tooth, especially when the light is angled across the surface. A visible crack line does not always mean the tooth is cracked through, which is one reason the photo is paired with testing.
Fillings, crowns and other dental work
The camera is useful for checking existing restorations. It can show a filling that has chipped, a gap or dark line at the edge of a crown, worn bonding or stain collecting along a margin. Seeing the edge of your own crown on a large screen often makes a recommendation to "watch" or "replace" much easier to understand.
Gums and soft tissues
Intraoral camera images can document red or swollen gums, areas where gums have pulled back from the tooth (recession), and plaque or tartar along the gumline. The camera can also photograph the cheeks, tongue and palate. That makes it a useful way to record a spot your dentist wants to watch, so its size and colour can be compared at a later visit.
Plaque, tartar and home-care habits
One of the best-supported uses of intraoral photography is patient education. The 2019 review of intraoral camera applications concluded that showing patients images of their own mouths can reinforce oral hygiene instructions and improve follow-through with home care. Seeing plaque sitting along a specific gumline tends to be more memorable than hearing "brush better near the back."
What an intraoral camera cannot do
An intraoral camera cannot see inside a tooth, under the gums or through bone. Light reflects off surfaces; it does not pass through enamel. That single fact sets the camera's main limits, and it is worth being clear about them.
| Question | Intraoral camera | Dental X-ray (radiograph) |
|---|---|---|
| Uses radiation? | No, visible light only | Yes, a low, controlled dose of ionizing radiation |
| Shows tooth surfaces, fillings and crown edges? | Yes, magnified and in colour | Shows outlines and density, not surface colour |
| Shows gums and soft tissues? | Yes, visible surface only | Soft tissue detail is limited |
| Shows decay between back teeth? | Usually not, unless it reaches a visible surface | Often, with bitewing views |
| Shows roots, bone levels or infection at the root tip? | No | Yes, depending on the view |
| Field of view | Small area at a time | A group of teeth, a full arch or more |
| Main role | Explaining, documenting and monitoring what is visible | Finding what is hidden |
Several other limits are worth naming:
- It does not diagnose on its own. A magnified photo can make a harmless stain look dramatic, and it can make a real problem look small. Diagnosis combines the photo with probing, testing, your history and, when indicated, radiographs.
- It does not replace periodontal measurements. Gum health is assessed by measuring pocket depths and checking for bleeding, not by colour alone.
- It is not an oral cancer test. The camera can photograph a sore or patch so it can be monitored, but it cannot tell whether tissue is abnormal. Suspicious areas may need further testing or referral whether or not a photo was taken.
- It has a narrow field of view. It shows one small area at a time, not the whole mouth. Wider views come from panoramic X-rays or 3D imaging when they are needed.
If you want to know more about the hidden side of the picture, our guide to intraoral cameras compared with dental X-rays explains how the two tools work together, and why dentists take X-rays covers when radiographs are recommended.
What to expect when the camera is used
Most patients notice a small wand, a bright light at its tip and their own teeth appearing on a screen. The camera may be used during a checkup, a visit for a sore tooth, or before and after treatment. If you would rather not watch, say so, and the team can describe findings in words instead.
Here is what a typical camera moment looks like from the chair:
- You may be asked to open wider, turn your head slightly or lift your tongue so the lens can reach a back tooth.
- The clinician may dry the area with air first. That can feel cool, especially on sensitive teeth.
- The tip may rest lightly against a tooth or hover just above it. There is no cutting, heat or vibration.
- The image appears on the monitor. You can ask the clinician to pause, enlarge or point to exactly what they are describing.
Questions worth asking while the image is on screen
The intraoral camera is most useful when it leads to a clear conversation. While the picture is visible, you might ask:
- What exactly are you pointing to, and is it new since my last visit?
- Is this something to watch, or something to treat?
- What would make you recommend treatment sooner rather than later?
- Do you need an X-ray or another test to be sure?
- Is there anything I should do differently at home for this spot?
A clear image should reduce confusion, not create pressure. If a magnified close-up looks alarming, ask how serious the finding is in real life and what options exist, including monitoring when that is appropriate.
Special situations - children, anxiety, gagging and dental work
An intraoral camera is a low-effort tool for most people, but a few situations are worth mentioning to the team before the visit.
Children. Many children are curious about seeing their teeth on a screen, and pictures can make brushing advice more concrete for both the child and the parent. The camera uses no radiation, so there is no dose concern. Very young children may not sit still long enough for a clear picture, and that is normal. For more on protective care for kids, see our guide to dental sealants.
Dental anxiety. Some anxious patients find it reassuring to see exactly what is happening instead of imagining it. Others prefer not to look. Either preference is reasonable; just say which you prefer.
A strong gag reflex. Placing the wand near the back molars can trigger gagging in some people. Tell the team first. Breathing through your nose, taking short breaks and photographing the back teeth quickly can help.
Pregnancy. Because the intraoral camera does not use X-rays, it carries no radiation concern during pregnancy. If X-rays are also being considered, tell the team you are pregnant, since the Canadian Dental Association advises that elective radiographs may be deferred and essential ones kept to the minimum needed.
Crowns, implants and orthodontic appliances. The camera can photograph the edges of crowns, the gum tissue around implant crowns and areas around braces or retainers, where plaque tends to collect. These photos can be useful for tracking how tissues respond over time.
How intraoral photos are stored and used over time
Saved intraoral camera images become part of your dental record, alongside chart notes and any radiographs. Their value grows over time, because a photo from one visit can be compared with a photo from the next.
Common reasons to keep an intraoral photo include:
- Baselines. A picture of a small crack, a stained groove or a patch of receding gum gives your dentist something concrete to compare against later.
- Before and after. Photos taken before and after a filling, crown or cleaning can show what changed.
- Explaining a plan. If treatment is recommended, a saved image can help you explain the plan to a family member or think it over at home.
Insurance and benefit plans have their own documentation rules. Some plans may ask for supporting images or radiographs for certain treatments, and others do not. Whether a photo is submitted with a claim depends on the plan and the procedure, so it is best not to assume either way.
If you would like a copy of an image for your own records, ask the front desk how the practice shares images through its usual privacy-compliant process. Photos are health information, and they are handled the same way as the rest of your chart.
Does using an intraoral camera change the cost of a visit?
Whether a separate fee applies for intraoral photos depends on the practice, the reason the images are taken and how your benefit plan treats them. Many offices use the camera as part of a routine exam conversation. If cost matters to you, ask before the visit, and if you have public or private coverage, ask the office to confirm what your plan covers. If you have questions about the Canadian Dental Care Plan, see our CDCP information page.
Intraoral camera exams in Truro and Colchester County
Landmark Dental Care is a family general practice at 125 Queen St in downtown Truro, in a Victorian Queen Anne–style home. The practice lists the intraoral camera among the tools it uses during examinations, along with digital X-rays and 3D CBCT imaging when they are clinically needed. Patients come from Truro, Bible Hill and across Colchester County and Central Nova Scotia, Monday to Friday, 8:30am to 5:00pm.
If you are new to the practice and have recent photos or X-rays from another office, bring the details or ask that office to transfer them. Recent images can help your new dentist compare what has changed and may avoid repeating X-rays that are still adequate.
Families with young children may find the camera especially helpful for showing where plaque builds up. Nova Scotia's Children's Oral Health Program, billed through MSI, covers basic dental care such as exams for eligible children aged 14 and younger with a valid Nova Scotia health card; check novascotia.ca for current details.
FAQ
Does an intraoral camera hurt?
No, an intraoral camera does not usually hurt, because it only takes pictures and does not cut, scrape or vibrate. You may feel a light touch or a cool puff of air when a tooth is dried. People with a strong gag reflex may find placement near the back molars uncomfortable, so mention it first.
Is an intraoral camera the same as an X-ray?
No. An intraoral camera takes colour photographs of surfaces using ordinary light, while an X-ray uses a small dose of radiation to show structures inside teeth and bone. They answer different questions, and your dentist may use both at the same visit.
Can an intraoral camera find cavities?
It can show decay that has reached a visible surface, such as a chewing groove or the edge of a filling. It usually cannot show early decay between back teeth or under an existing filling, which is why bitewing X-rays are still recommended when your risk calls for them.
Can I see the photos my dentist takes?
Usually, yes. The main reason to use an intraoral camera is so you can see what your dentist sees on a screen. If you want a copy for your records, ask the office how images are shared under its privacy process.
Why did my dentist take a photo of something that looks fine?
A photo can serve as a baseline. If a spot, crack line or area of gum recession needs watching, a clear picture today lets your dentist compare it at the next visit instead of relying on memory.
