At every visit we turn the screen toward you and walk through your x-rays together, because you should never have to take our word for what is happening in your own mouth. Here is a short guide to reading them yourself.
Why we show you at all
An x-ray is simply a map of what a mirror cannot see: between teeth, below fillings, and under the gumline. Showing you the map is how we make our reasoning visible, so a recommendation is something you can see for yourself rather than something you are asked to trust.
The bright bits and the dark bits
On a dental x-ray, the harder and denser something is, the brighter it shows. Enamel and old metal fillings look bright white. Softer, decayed areas look darker, like a shadow creeping in from the side of a tooth. That shadow is usually what we are pointing at when we mention a small cavity.
| Bright white | Dense material, so enamel or an old metal filling. The brighter it is, the harder it is. |
|---|---|
| Dark shadow | A softer, less dense area creeping in from the side of a tooth. Usually early decay. |
| Even bone line | A steady, high line of bone between the teeth. The quiet fingerprint of healthy gums. |
| Dipping bone line | Bone that has receded below where it should sit. An early, visible sign of gum disease. |
| Dark halo at a root tip | A shadowed area around the very end of a root. Sometimes a sign of infection to watch. |
Reading the bone and the roots
The steady line of bone between your teeth should sit high and even. When it dips or recedes, that is the quiet fingerprint of gum disease, visible on film long before it is felt. The roots and the space around them tell us whether a tooth is settled and healthy underneath.
Questions are the point
You cannot break anything by asking what a spot is, and there is no such thing as a silly question about your own body. The whole reason the screen faces you is so you can point and ask. The more you understand, the better every decision about your care becomes.
