Dental X-rays are a cornerstone of modern, preventive dentistry. They reveal concerns that are not visible, guide precise treatment, and help keep care conservative. If you are searching for dental X-rays in Ottawa or wondering why X-rays are important, this guide explains how imaging works, what it shows, and how we keep exposure as low as reasonably achievable. Our goal is to provide clear, reassuring information that helps you feel confident about your oral health and every step of your visit at Florence Dentistry in downtown Ottawa.
X-rays are used thoughtfully and only when they meaningfully support diagnosis or treatment. With today’s digital technology and safety protocols, dental radiographs are quick, comfortable, and tailored to your needs. Most importantly, they allow problems to be found early, when solutions are simpler and more comfortable.
What dental X-rays show that a visual exam cannot
A careful visual exam is essential, yet many dental issues start beneath the surface. X-rays complement what your dentist sees and feels during an exam by revealing:
- Decay between teeth and under existing fillings that is hidden from view
- Infections at the tooth root, including early abscess changes
- Bone levels around teeth to assess gum health and detect early periodontal changes
- Tartar deposits under the gums that may not be visible above the gumline
- The full length of each tooth, including the roots and surrounding bone
- Tooth development and position in children, teens, and young adults
- Wisdom tooth position and proximity to nearby structures
- Cysts or other changes that require monitoring or treatment
By identifying issues in their early stages, X-rays make it possible to treat small problems before they become larger ones, protecting your comfort, time, and budget.
Types of dental X-rays you may need
Modern dentistry relies on a few main types of dental X-rays. Your dentist will recommend the images most appropriate for your age, health, and current concerns.
Bitewing X-rays
Bitewings are the most common type taken during routine checkups. They capture the crowns and upper portions of the roots of the back teeth on the upper and lower jaws in a single view, making them ideal for detecting decay between teeth and monitoring bone levels over time. Bitewings are quick to capture and provide a detailed look at areas that are otherwise hard to assess.
Periapical X-rays
Periapical images show an entire tooth from crown to root tip, as well as the surrounding bone. They are especially useful when you have symptoms like lingering sensitivity, a localized ache, or tenderness when biting. These images help evaluate root health, identify infections, and assess changes around the tip of the root.
Panoramic images, when appropriate
A panoramic image provides a broad overview of both jaws, the jaw joints, and the sinuses. It can help assess tooth development, evaluate wisdom tooth position, and screen for larger changes. Panoramic imaging is recommended only when it benefits diagnosis or treatment planning.
Safety and radiation, how we keep exposure low
Patient safety is central to our imaging protocol. Dental X-rays use a very small amount of radiation, and modern digital sensors reduce exposure compared with older film systems. At Florence Dentistry, we follow the ALARA principle (as low as reasonably achievable), which means we take only the images that are necessary for accurate diagnosis and care.
- Digital technology: Digital sensors are highly sensitive, which allows for clear images with minimal exposure.
- Protective measures: When indicated, a lead apron and a thyroid collar are used to shield areas of the body that are not being imaged.
- Tailored approach: We consider your age, dental history, cavity risk, and current symptoms when deciding which images to take and how often to take them.
- Context for peace of mind: The exposure from routine dental X-rays is small and comparable to the background radiation we experience in daily life.
If you are pregnant or think you might be, let us know. Dental X-rays may still be recommended in specific situations when the benefits outweigh the risks, and additional safeguards are used. Your dentist will discuss timing and necessity with you so you can make an informed decision.
How often are dental X-rays recommended?
There is no single schedule that fits everyone. Your X-ray interval is personalized based on your cavity risk, gum health, and dental history.
- New patients: Baseline images are typically recommended to understand your current oral health. This may include bitewings and, when appropriate, other views to complete the picture.
- Low cavity risk: Patients with healthy gums and low decay risk may need bitewings roughly every one to two years.
- Higher cavity risk: If you have a history of decay, dry mouth, multiple restorations, or other risk factors, bitewings may be recommended more often to catch changes early.
- Children and teens: Because enamel on new teeth is more vulnerable and changes can happen quickly, more frequent monitoring may be suggested during growth years.
- Periodontal considerations: If you are being monitored for gum disease, periodic images help track bone levels and support a targeted maintenance plan.
- Pregnancy and special situations: Imaging is used only when necessary and with additional safety measures, focusing on the most informative views that support your care.
Your dentist will explain why a specific set of images is recommended at a given visit and how those images guide your care.
What to expect during a dental X-ray appointment
Dental X-rays are designed to be quick and comfortable. Here is a simple overview of what you can expect:
- Preparation: You may be asked to remove glasses, earrings, or removable dental appliances that could interfere with the images.
- Positioning: For bitewings and periapicals, a small digital sensor is placed gently in your mouth. Clear instructions and a few seconds of stillness are all that is needed. For a panoramic image, you will stand or sit while the machine moves around your head to capture the full view.
- Comfort tips: If you have a strong gag reflex or a smaller mouth, let us know. We have strategies to make the process smoother, such as adjusting sensor placement, using cushioning, or starting with the least challenging images first.
- Hygiene and infection control: Sensors are covered with single-use barriers, and all equipment is disinfected according to strict protocols.
- Timing and review: Most image sets take only a few minutes. Your dentist will review the images with you, point out any findings, and explainthe next steps if needed.

Myths and facts about dental X-rays
Understanding the role of X-rays can help you make informed choices about your care.
- Myth: X-rays are unnecessary if nothing hurts. Fact: Many dental problems are painless at first. X-rays reveal issues early, so treatment stays simple and comfortable.
- Myth: Radiation from dental X-rays is high. Fact: modern digital X-rays use a very small amount of radiation, and protective measures further reduce exposure.
- Myth: Everyone needs the same X-rays every year. Fact, frequency, and type are personalized based on your health, history, and risk level.
- Myth: X-rays are only for cavities. Fact, they help monitor gum health, check roots and bone, evaluate tooth development, and screen for broader changes.
How X-rays support precise, conservative care
X-rays are valuable because they make care more targeted and less invasive:
- Early detection means smaller fillings and faster appointments
- Clear views of roots and bone guide decisions when a tooth feels sore or sensitive
- Tracking bone levels helps plan cleanings and home care strategies that protect your gums
- Images taken after treatment confirm healing and reinforce that the plan is working
- Baseline records allow your dentist to compare images over time and spot subtle changes
When you understand why X-rays are important, it becomes easier to see how they fit into a preventive approach that preserves your natural teeth and avoids surprises.
Costs, insurance, and planning your care in Ottawa
The cost of dental X-rays depends on the number and type of images needed. Many dental benefit plans include coverage for routine bitewings at checkups and may cover additional images when they are required for diagnosis. If you have benefits, a pre-treatment estimate can clarify expected coverage before your visit. If you do not have coverage, we will explain the recommended images, why they are needed, and the associated fees so you can make a confident decision.
Remember that X-rays often reduce overall costs by catching concerns early, which helps avoid extensive treatment. Pairing regular exams with the right imaging schedule is one of the most effective ways to maintain long-term oral health.
