X-rays are an important diagnostic tool that help your dentist assess your oral health accurately.
Your dentist may recommend X-rays to:
- Identify decay that isn't visible during a routine visual examination
- Assess bone levels and detect any changes over time
- Check for decay developing beneath existing fillings
- Look for signs of infection near a tooth's root or the surrounding bone
- Give your dentist a clearer picture of the area before recommending treatment
X-rays are only recommended when clinically necessary, based on your individual dental history and needs, and are one part of a broader clinical assessment by your dentist.
