Can root canal treatment be seen on X-rays?

Hello, Director Lin.
About 18 years ago, I was hit in the mouth by the metal edge of a badminton racket while playing badminton, which severely injured my two upper front teeth (tooth numbers 11 and 21).
One of them was treated with root canal therapy and a crown was placed, while the other was treated by "filling the gap," but I don't recall whether root canal treatment was performed on that tooth.
Recently, the tooth that was filled has partially broken due to biting into something hard.
I would like to ask if a dentist can determine whether root canal treatment was done by visual examination or X-ray (since the paper medical records are too old to retrieve)? Additionally, since the area of the breakage is limited to about 60% of the filling material and does not seem to have affected the tooth itself, and I am currently not experiencing any pain, can this be managed by refilling the gap?

Yes, X-rays can indeed reveal past root canal treatments in dental care. When a tooth undergoes a root canal procedure, certain changes occur that can be detected on X-ray images. These changes include the presence of a root canal filling material, which appears radiopaque (white) on the X-ray, contrasting with the surrounding tooth structure and any potential decay or infection, which may appear radiolucent (dark).
In your case, since you have two upper front teeth (11 and 21) that were treated differently, an X-ray can help determine which tooth underwent root canal treatment. The tooth that received the root canal will show evidence of the filling material within the root canals, while the other tooth, which was simply repaired, will not exhibit such findings.
It's important to note that while X-rays are a valuable diagnostic tool, they are not the only method for assessing the condition of a tooth. A dentist will also consider clinical findings, such as the tooth's response to percussion or temperature tests, to evaluate the health of the tooth and surrounding tissues.
Regarding your concern about the tooth that had the filling material break, if the fracture is limited to the filling and there is no pain or other symptoms, it is likely that the tooth itself remains intact. In many cases, a dentist can simply replace the broken filling material. However, the decision to proceed with this approach should be made by a dentist after a thorough examination. They will assess the extent of the damage and determine if the tooth structure is sufficient to support a new filling.
If the tooth has significant structural loss or if there are signs of underlying issues, such as decay or infection, more extensive treatment may be necessary. This could include a new root canal treatment, a crown, or other restorative options, depending on the condition of the tooth.

In summary, X-rays are a crucial part of dental diagnostics and can effectively reveal past root canal treatments. If you have concerns about the integrity of your teeth or the need for further treatment, I recommend scheduling an appointment with your dentist for a comprehensive evaluation. They can provide you with the best course of action based on your specific situation and ensure that your dental health is maintained.
