A dark spot in an x-ray can mean the presence of a cavity. It is a sign that bacteria have attacked the enamel and are entering the dentin. This decay must be addressed as soon as possible.
Structures that are dense (such as bone) will block most of the x-ray waves, and will appear white. Metal and contrast media (special dye used to highlight areas of the body) will also appear white. Structures containing air will be black, and muscle, fat, and fluid will appear as shades of gray.
Overexposure results in a high-density or dark image. The causes include improper exposure factor settings or improper assessment of patient size and stature.
Tooth Decay
These holes tend to look like small black or brown spots on your teeth. A black spot of tooth decay is usually accompanied by: Persistent pain or toothache. Tooth sensitivity to hot and cold temperatures and sugary foods or drinks.
Generally speaking, a dental cavity (also called tooth decay) can range in color from white to brown and eventually black as the cavity continues to grow.
Internal causes
The tooth may also appear black when damage occurs from the inside. The most common causes of black teeth in these cases are decay or cavities. For example, a tooth with a pulp infection or a dead tooth may turn black. The damage starts on the inside and works its way to the surface.
A tooth that has an abscess at its root is generally sensitive to touch or pressure. Recommend an X-ray. An X-ray of the aching tooth can help identify an abscess. Your dentist may also use X-rays to determine whether the infection has spread, causing abscesses in other areas.
What can dental X-rays detect? Dental X-rays help your dentist diagnose a wide range of oral health issues. Dental X-rays show: Cavities, especially small areas of decay between teeth.
A dental X-ray can also help dentists see developing decay, if wisdom teeth are starting to emerge, or if teeth are impacted and unable to push through the gums.
It is often used symbolically or figuratively to represent darkness. Black and white have often been used to describe opposites such as good and evil, the Dark Ages versus Age of Enlightenment, and night versus day.
Density is the overall darkness (blackness) of an image. Contrast is the difference in lightness and darkness between areas on a radiograph. The goal in dental radiology is to use techniques that require the least amount of radiation exposure to produce images with the right amount of density and contrast.
Objects which are black in colour will absorb all the light which is falling on them and will reflect none. Hence, no light reaches our eye and the objects appear black.
X-Ray Photo
It is a dark shadow between the arrows. This shadow represents a “hole” or “tunnel” through the protective enamel of the tooth where bacteria now has access to the soft inside portion of the tooth.
3. Infections: X-rays can also help dentists detect infections that may be present in the gums, jawbone, and other areas of the mouth. This is important for identifying and treating problems like abscesses before they become severe.
When the dentist looks at your teeth, the ideas of bad versus good are not a concern. However, the condition of your teeth can provide the dentist with some very important clues about you, and these clues help the doctor to make sure that you're receiving the very best dental care.
Can You See a Failed Root Canal on X-ray? Yes. Endodontists use X-rays to find and treat a failed root canal because it's often hard to see any problems with the naked eye.
An X-ray won't show subtle bone injuries, soft tissue injuries or inflammation. However, even if your doctor suspects a soft tissue injury like a tendon tear, an X-ray might be ordered to rule out a fracture.
In the majority of cases, you will notice some type of symptom that indicates an infected root canal. Although, there are cases where there are no symptoms and the infection will only be found by your dentist on an x-ray.
Decays and cavities or pulp infections can cause black teeth surfaces too. The effect does not show immediately after the onset of the infection. It takes time, but you may notice the warning signs that the tooth's surface gives if you look closely.

So once decay reaches your dentin, the process of decay speeds up. As the bacteria and acids work their way through your dentin, the cavity hole gets larger. At this point, you may notice your cavity is brown or black in color. Your dentist will probably recommend a filling to stop the progress of the cavity.
toothache – either continuous pain keeping you awake or occasional sharp pain without an obvious cause. tooth sensitivity – you may feel tenderness or pain when eating or drinking something hot, cold or sweet. grey, brown or black spots appearing on your teeth. bad breath.
Tooth decay causes dark spots to form on the surface of the teeth as a cavity grows. This discoloration is often mistaken for common staining caused by coffee, tea, or smoking. Inspect teeth regularly to spot early discoloration changes.
Black objects absorb all the light shined on them. There is no reflected light, so we see black (the absence of color). If all of the light is reflected, we see all the wavelengths, which means we see white light.
