First, a cavity can only be seen on an x-ray once it has dissolved 20-30% of the tooth structure so it may not have been obvious last visit. And cavities can grow fast on some patients! Second, some teeth have rotations and malalignments that cause cavities to be very elusive from standard x-ray positions.
Another reason decay may not show up on your x-ray is that it could have started after your last set of x-rays. Your teeth are susceptible to decay all of the time, especially if you eat sugary or high acid foods. It is quite possible your decay did not develop until after your last dental exam and last set of x-rays.
Not all cavities are visible to the naked eye. If you can see a cavity in your mouth, it's usually dark brown or black. Common places to see them are on the chewing surfaces of back teeth or along the gumlines.

An infected root canal system may or may not show up on an x-ray. However, an x-ray can help your dentist determine if the infection has spread to the surrounding bones.
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.
Your dentist can also use X-rays to determine if the infection has spread and may be affecting other areas. Recommend a CT scan: If the infection has spread to other areas within your neck, this will help to identify the extent of the infection.

The dentin layer is between the enamel and the pulp. The purple arrows are pointing to areas of decay, which show up as a dark spot on x-rays. Bacteria have attacked the tooth and have dissolved the enamel and entered the dentin. The decay must be removed before it dissolves the dentin and enters the pulp.
A visual examination can also be performed to detect cavities. Teeth that are discolored, whether it is brown or black, can indicate a dental cavity. Dental x-rays or check-ups or bitewing x-rays, are additional useful options for locating cavities between teeth or beneath the gum-line.
Symptoms of tooth decay
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.
These hidden cavities form when a build-up of plaque forms in hard-to-reach places in your mouth. If hidden dental caries go untreated, or worse, unnoticed, they can become more painful as the enamel and dentin become destroyed.
The time it takes for a cavity to form varies. It can, on average, take anywhere from six months to four or five years before a cavity requires treatment. The length of time it takes will vary on a case-by-case basis because the conditions of your mouth differ daily.
This metal makes it impossible for the tooth structure inside of the crown to be seen on a radiograph (x ray). When decay under a crown is small, it is often difficult to detect. On a radiograph (x ray), the x ray beam would have to be placed at precisely the right angle to see the decay.
Most Teeth Can Be Corrected
While sometimes their tooth decay was advanced enough to be a serious problem, a simple cavity can be surprisingly painful. So, it is important not to wait until you can't stand the pain and discomfort and have treated sooner rather than later.
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.
If a Cavity Hurts, Is it too Late for the Dentist? If your cavity hurts, it's not too late for a dentist to save your tooth. When cavities are small, they tend not to hurt too much, but they'll start to cause pain as they grow. That's usually when you notice them.
X-Ray Results Can Show Hidden Infections
In many cases, infections within the body can hide for weeks or even months, spreading without you even knowing it exists. With an x-ray scan, you can find the problem before it's too late.
What's The Takeaway? To summarize, a dentist can easily pull an infected tooth out. However, to prevent the bacteria from infecting other sites, dentists prefer to either drain the abscess or reduce the infection with the help of antibiotics first. This way, there won't be any alarming results after.
A cavity is usually treated by removing the decayed part of the tooth and filling the hole with a tooth-colored filling. However, if the cavity is too deep, you may need a crown, root canal, or extraction. A tooth infection, on the other hand, is treated by draining the abscess and removing the infected pulp.
Reasons for Pain Years Later Following a Root Canal
Sometimes a tooth does not fully heal, and the infection returns later. Cleaning the infection from curved canals in tooth roots can be difficult for a dentist. If the infection persists, the tooth will become problematic in the future.
An obstruction within the canal that prevents the dentist from reaching the end of the canal. Calcified canals. If the tooth is infected, time may be needed in order to allow infection to completely clear.
Occasionally, a tooth can't be saved because the root canals are not accessible, the root is severely fractured, the tooth doesn't have adequate bone support, or the tooth cannot be restored. However, advances in endodontics are making it possible to save teeth that even a few years ago would have been lost.
In general, adults develop an average of three cavities during their lifetimes. This means that the average adult has three or four fillings in their mouth. Some patients end up with ten or more fillings depending on how well they care for their teeth.
