Dental caries is one of the most common dental problems and can cause significant discomfort if not detected and treated in time. The good news is that there are clear signs and symptoms you can identify to know if you have caries. In this article, we guide you through these indicators and offer tips to keep your teeth healthy.
🏠 How to know if you have caries at home?
🔍 Identifying the first signs
Early detection of caries is crucial to avoid greater complications. Some of the first signs you can identify at home include dental sensitivity when consuming hot, cold, sweet, or acidic foods or beverages. This sensitivity is due to the erosion of dental enamel, which exposes the dentin, a more sensitive layer of the tooth.
🔎 Simple self-diagnosis
Another way to self-diagnose the presence of caries is by observing your teeth in the mirror.
Another way to self-diagnose the presence of caries is by observing your teeth in the mirror. Look for dark spots or areas that appear more opaque. You can also feel with your tongue for irregularities or small bumps on the surface of the teeth. If you notice any of these symptoms, it is advisable to visit a professional dentist for a more detailed evaluation.
🚨 What symptoms indicate that you have caries?
🔥 Dental sensitivity
Dental sensitivity is one of the most common symptoms of caries. It can manifest as a sudden sharp pain when biting or consuming very hot or cold foods and beverages. This pain is the result of the exposure of the dentin, which is more sensitive to external stimuli.
🦷 Toothache
Persistent or recurrent toothache can also be an indicator of caries. This pain can be constant or may worsen when chewing or applying pressure to the affected tooth. If you experience this type of pain, it is important not to ignore it and seek professional dental care for an accurate diagnosis and appropriate treatment.

🔍 How to identify early-stage caries?
In the early stages, caries can be difficult to detect with the naked eye, but there are some signs you can look for.
👀 Visual observation
In the early stages, caries can be difficult to detect with the naked eye, but there are some signs you can look for. White or brown spots on the surface of the tooth are an early indication of the presence of caries. These spots form when the acid produced by bacteria begins to erode the dental enamel.
🌡️ Sensitivity tests
Another way to identify early-stage caries is by performing sensitivity tests. You can apply a little cold or hot water to the suspected tooth and observe if you feel any discomfort. If you notice sensitivity, it is likely that you are in the early stages of caries. Dentists use advanced techniques and high-precision equipment to detect caries in their early stages, allowing for more effective treatment.
| Caries Stage | Visual Signs | Symptoms |
|---|---|---|
| Initial Stage | White or brown spots | Sensitivity to temperature changes |
| Advanced Stage | Visible cavities | Constant pain, gum swelling |
🚨 How to know if you have deep caries?
Deep caries is characterized by intense and constant pain that can radiate to other parts of the mouth or face.
💥 Intense pain
Deep caries is characterized by intense and constant pain that can radiate to other parts of the mouth or face. This pain is the result of caries that has penetrated to the dental nerve, causing inflammation and severe pain. If you experience this type of pain, it is crucial to seek immediate dental care to avoid more serious complications.
🚨 Inflammation and abscesses
Another symptom of deep caries is inflammation of the gums around the affected tooth. In some cases, an abscess may form, which is a pus-filled pocket that develops at the root of the tooth. The presence of an abscess is a serious indicator that the caries has significantly advanced and requires immediate treatment. Professionals are trained to handle these cases efficiently and safely.
🌙 What discomfort does deep caries cause?
🍴 Pain when chewing
Deep caries can cause considerable pain when chewing. This is because the caries has reached the dentin and, in some cases, the dental nerve. Chewing on the affected tooth can result in sharp, stabbing pain, making eating a painful and unpleasant task.
😴 Difficulty sleeping
The toothache caused by deep caries can be so intense that it interrupts sleep. The pain may worsen at night when the body is at rest and there are no distractions. If you have difficulty sleeping due to dental pain, it is important to consult a dentist to receive appropriate treatment and relieve the pain.
🔎 What does a caries look like on teeth?
👀 Visual appearance
A caries on the teeth can present a variety of visual aspects depending on its stage of development. In the early stages, it may appear as white or brown spots on the surface of the tooth. As the caries progresses, these spots may darken and become visible cavities. In more advanced stages, the teeth may show fractures or cracks due to the weakening of the enamel.
🔎 Changes in the surface of the tooth
In addition to color changes, caries can cause changes in the surface of the tooth. You may notice irregularities, bumps, or areas that feel softer to the touch. These changes are the result of the erosion of the enamel and dentin, which weakens the structure of the tooth. If you notice these changes, it is important to visit a dentist for a professional evaluation.
🚨 What changes in the tooth alert about caries?
🔥 Increased sensitivity
An increase in dental sensitivity is one of the first signs that something is wrong with your teeth. If you notice that your teeth are more sensitive to temperature changes, sweet or acidic foods, or if you experience pain when chewing, you are likely developing caries. The sensitivity is due to the exposure of the dentin, which is more sensitive to external stimuli.
🎨 Color changes
Color changes in the teeth can also be an indicator of caries. White or brown spots are early signs of enamel erosion. As caries progresses, these spots may darken and become visible cavities. If you notice changes in the color of your teeth, it is important not to ignore them and seek professional dental care.
| Signs of Caries | Description |
|---|---|
| Increased sensitivity | Greater sensitivity to temperature changes, sweet or acidic foods |
| Color changes | White or brown spots, darkening of spots |
🔬 How does caries evolve if not detected in time?
🔬 Formation process
Dental caries begins with the accumulation of bacterial plaque on the surface of the tooth. This plaque, composed of bacteria and food debris, produces acid as a byproduct of its metabolism. The acid erodes the dental enamel, the outermost and protective layer of the tooth. If left untreated, caries can progress to the dentin, the intermediate layer that is more sensitive and less resistant to erosion. In more advanced stages, caries can reach the dental nerve, causing intense and constant pain, and an abscess may develop.
The progression of dental caries can be silent in its early stages, causing many people not to realize its presence until the symptoms become evident.
The progression of dental caries can be silent in its early stages, causing many people not to realize its presence until the symptoms become evident. However, once pain appears, it is a clear indication that caries has significantly advanced. At this point, treatment may be more complex and costly, including the need for root canal treatment or even extraction of the affected tooth. Therefore, prevention and early diagnosis are crucial, as they can prevent these complications.
If caries is not detected and treated in time, it can cause serious complications, such as tooth loss, oral infections, and general health problems. Advanced caries can affect quality of life, making chewing, speaking, and dental aesthetics difficult. Additionally, oral infections can spread to other parts of the body, increasing the risk of cardiovascular and respiratory diseases. That is why it is important to regularly attend dental check-ups, where professionals can detect and treat caries in its early stages, avoiding greater complications.
