Most of the time.
Yes an infection will be visible on xrays
Yes, majority of the times.
Root canal infections may show up on x-rays, but only if the infection has been present for quite sometime. The real sign that you need a root canal is if you have spontaneous throbbing/aching pain that may radiate, the pain causes you to wake up at night, and you have pain to hot/cold food or drinks. Most infections that need a root canal will not show up on the x-ray, but are diagnosed via symptoms you are experiencing.
Not always, but many times it does. Most times, we diagnose an infected tooth by means of various different tests. One is a cold test, and this tells a lot about the vitality if the tooth.
That depends. Generally if the infection is acute, it does not show on the x ray but if it is chronic (it has been there a while) then it may show on the x Ray.
Chronic root canal infections that have been there for a long time will often show up on an X-ray. However, more recent root infections may not show up at all. This is because enough bone has to be destroyed before the density is such that it will show up on a radiograph.

Not necessarily. In many cases sumptoms and more tests are needed or even a cone beam xray would help to confirm the diagnosid
X-rays do not show bacteria. If bacterial infection does damage to the bone or tooth, then x-ray will indicate.
A majority of the time we can see an infection on your x-ray - at the tip of the root you will see a dark shadow (radiolucency). There are times that a tooth will not present that way, for example there could be decay that goes into the nerve and hasn't created a pulpal (nerve) infection, yet; these teeth tend to be symptomatic/painful.
Yes, an infection can be seen on an x-ray which would signify that a tooth is in need of a root canal. This is often presented as a dark area surrounding the tip of the root of a tooth, or tooth decay or a large filling that is seen close to the nerve of the tooth. But to be clear, this is not always visible on an x-ray.
Other things must be evaluated such as possible symptoms of pain or sensitivity, and knowing the history of the tooth (ie, if it’s had trauma, deep cavities, or history of a deep filling).
If a tooth already has a root canal and has a re-infection, then yes the infection can also be seen on a dental x-Ray.
X-rays are extremely important because sometimes a tooth can have zero pain even if an infection is present. Hope this answers your question!

Yes a dental infection can show-up on an x-ray. The tooth in question should have additional testing to determine the vitality of the tooth.
