Dental x-rays are fast, easy, and one of the simplest ways we can spot problems early, even before you feel a thing. At Sullivan Dental Partners, we hear questions about x-rays all the time:
- “Do I really need dental x-rays every year?”
- “Aren’t x-rays dangerous?”
- “Can’t you just look at my teeth?”
These are great questions, and you deserve clear answers. So let’s break it down!
Why Are Dental X-Rays Important?
Your dentist can only see about 30–40% of your tooth without x-rays. The rest is hidden under enamel, between teeth, and below the gumline, which is exactly where a lot of dental problems like to start. Dental x-rays help us catch issues early, while they’re still small, manageable, and often less expensive to treat.
What Can Dental X-Rays Detect Early?
Dental x-rays allow us to spot problems that are invisible to the naked eye, including:
- Cavities Between Teeth — X-rays help us detect these cavities early, before they become deep and painful.
- Tooth Infections — X-rays help us identify infection before it causes swelling or severe pain.
- Bone Loss from Gum Disease — X-rays help us measure bone levels and catch periodontal issues before they lead to tooth loss.
- Cracks, Trauma, and Damage — X-rays help us check for hidden fractures or structural damage.
- Wisdom Teeth Issues — Wisdom teeth can cause crowding, impaction, infections, and pain, and they often do it before you can see or feel anything.
“But I’m Not in Pain. Do I Still Need X-rays?”
This is one of the biggest misconceptions in dentistry. Pain is not an early warning sign; it's usually a late-stage symptom. A cavity doesn’t typically hurt until it’s deep. Gum disease often doesn’t hurt until it’s advanced. And infections can quietly develop long before they flare up. That’s why dental x-rays are so valuable: they help us find issues while you still feel totally fine.
Are Dental X-rays Safe?
Yes, modern dental x-rays are extremely safe, especially when done appropriately. Dental x-rays use a very small amount of radiation. At Sullivan Dental Partners, we also take safety seriously and use best practices to minimize exposure, including:
- Digital imaging (lower radiation than traditional film)
- Protective shielding when appropriate
- Only taking x-rays when clinically necessary
How Often Do You Need Them?
The truth is: it depends on you. Someone with a history of frequent cavities may need x-rays more often than someone with a low risk. Kids and teens may need them more frequently because their teeth and jaws are changing. Adults with stable dental health may need them less often.
How In-House Imaging Technology Improves Your Care
One of the biggest advantages of Sullivan Dental Partners is that we use in-house dental imaging technology right here in our Brentwood dental office.
Faster Answers (Less Waiting)
When imaging is done in-house, we can take x-rays and review them immediately, often during the same visit.
Better Accuracy and Clearer Treatment Planning
Modern digital x-rays are clear and zoomable, helping us catch early decay, check bone levels, and evaluate tooth structure with confidence.
Better Communication Between Dentist and Patient
A huge part of good dentistry is trust. When we can show you what’s going on, you can make informed decisions. At Sullivan Dental Partners, we don’t want you to feel pressured into treatment. We want you to feel educated and comfortable.
Common Myths About Dental X-Rays
Myth #1: “If I brush and floss, I don’t need x-rays.”
Brushing and flossing are essential, but they don’t prevent every cavity, crack, or infection. X-rays are still needed for early detection.
Myth #2: “X-rays are only for cavities.”
Nope. Cavities are just one part of the story. X-rays help us evaluate roots, bone, infection, and overall oral health.
Myth #3: “X-rays are dangerous.”
Modern digital dental x-rays are low-dose and safe when used appropriately. We also limit X-rays to what’s clinically necessary.
