Dental X-rays are an important part of your child’s oral health care, helping dentists detect problems that cannot be seen during a routine check-up. But many parents in Singapore often ask:
“When should my child get dental X-rays?”
“Are dental X-rays safe for kids?”
“How often are they needed?”
This complete, research-backed guide explains the recommended age, frequency, safety and benefits of dental X-rays for children—so you can make informed decisions about your child’s oral health.
What Are Dental X-Rays & Why Are They Important?
Dental X-rays (radiographs) are images that help dentists see areas of the teeth, roots, gums, jawbone and surrounding structures that are not visible during a visual exam.
They help detect issues such as:
- Cavities between teeth
- Decay under fillings
- Gum and bone problems
- Missing or extra teeth
- Abnormal tooth development
- Impacted teeth
- Early signs of cysts or infection
According to research, dental X-rays allow dentists to diagnose hidden problems early—before they become painful or complicated to treat.
When Should Children Get Their First Dental X-Ray?
There is no fixed age, as it depends on the child’s oral health and cavity risk. However, general guidelines include:
Ages 1–3: First Dental Visit
- X-rays are usually not needed unless:
- There are visible cavities
- Trauma has occurred
- Teeth have unusual spacing or development
Most children do not need X-rays at this age.
Ages 3–6: Early Childhood
- Bitewing X-rays may be recommended if:
- The child has a high risk of cavities
- Dentists cannot visually inspect all tooth surfaces
This is often when children receive their first dental X-ray.
Ages 6–12: Mixed Dentition (Baby + Permanent Teeth)
As permanent teeth start coming in, X-rays help monitor:
- Tooth eruption patterns
- Jaw development
- Cavities between new teeth
- Potential orthodontic needs
Most children need periodic X-rays during this stage.
Ages 12+: Teens & Pre-Orthodontic Stage
X-rays help assess:
- Wisdom teeth development
- Bite alignment
- Orthodontic (braces/Invisalign) planning
- Early detection of gum issues
This age group may require panoramic or cephalometric X-rays depending on needs.
Are Dental X-Rays Safe for Children?
Yes—modern dental X-rays are considered safe for kids.
Digital X-ray technology emits very low radiation, much lower than traditional film X-rays. Protective equipment such as lead aprons and thyroid collars further minimize exposure.
Safety Measures Used in Children’s Dentistry
- Low-dose digital radiography
- Age-appropriate child settings
- Protective shield for body and thyroid
- X-rays taken only when necessary
According to research, the risk from dental X-rays is extremely low, while the benefit of early diagnosis is significant.
How Often Do Children Need Dental X-Rays?
X-ray frequency depends on cavity risk, dental history and oral hygiene:
Recommended Frequency
| Risk Level | How Often X-Rays Are Needed |
| Low Risk | Every 12–24 months |
| Moderate Risk | Every 6–12 months |
| High Risk | Every 6 months or as recommended |
High risk includes children with:
• previous cavities
• poor oral hygiene
• deep grooves in teeth
• dietary habits high in sugar
Benefits of Dental X-Rays for Children
Dental X-rays provide essential information that prevents future dental problems.
Key Benefits
- Detect hidden cavities early
- Monitor growth of permanent teeth
- Identify missing or extra teeth
- Detect impacted teeth or crowding
