When patients develop dental caries, it is recommended that they visit a formal medical institution for treatment. If the tooth decay is not addressed, it may worsen significantly. While it may not always cause pain, the teeth can still be damaged. Over time, the teeth might deteriorate severely, potentially leaving only the roots. This could also lead to damage to the tooth roots, causing inconvenience in the patient's dietary life and might lead to severe complications later on, including pain and irritation to the gum tissue. Therefore, it is advised that patients seek early medical treatment and undergo appropriate therapeutic measures based on the condition of their dental caries.

How to treat a cavity that has decayed to the root of the tooth?

For a tooth decayed to the root, it is first necessary to take an X-ray of the tooth. If the X-ray shows that the root still has some salvage value, the tooth can be preserved through root canal treatment after controlling the inflammation. If the decay has reached the tip of the root and the root has no salvage value, the tooth needs to be extracted soon after controlling the inflammation. After the tooth is extracted, it is necessary to get a dental prosthesis as soon as possible depending on the condition of the tooth. If the prosthesis is not done in time, the tooth above may elongate, and the teeth on either side may tilt towards the gap, potentially leading to the loss of space over time.

Can cavities be seen with the naked eye?

Some cavities are visible to the naked eye, while others are not. Clinically, some cavities can be observed with the naked eye. Such cavities usually have damage that extends beyond the enamel, with obvious cavities and incomplete tooth structures visible. For example, cavities on the biting surfaces of molar teeth and on the adjacent surfaces of front teeth that are moderate to severe can be seen with the naked eye. However, not all cavities can be observed with the naked eye. When the decay is confined within the enamel without obvious cavity formation, it cannot be seen with the naked eye, but it can be diagnosed by taking dental X-rays. Clinically, there are also some cavities on adjacent surfaces where the decay starts from hidden parts of the tooth; some of these might show ink-soaked-like dark brown discoloration on the biting surfaces, but they too require dental X-rays for diagnosis.

Can a decayed tooth be extracted?

Whether a tooth with caries can be extracted depends on the extent of the decay. If the decay is shallow, it can be treated with a one-time filling. If the decay is deep, reaching the nerve, nerve-killing treatment is required, followed by anti-inflammation measures and, after inflammation control, root canal filling. In other words, teeth should be preserved through root canal treatment whenever possible and not extracted. If the caries has reached the deep layers of the tooth dentin, or is at risk of causing a perforation, such conditions are considered non-salvageable and the tooth should be promptly extracted. After extraction, timely dental prosthetics should be placed.

How to treat a tooth that is half decayed?

When a patient has a cavity that has already damaged the dental tissues, causing severe damage to the dental tissues, the general advice for the patient is to go directly to a regular dental hospital for treatment. The best approach is generally to extract the tooth; extraction is the best option, but it should be done when the body is in good condition to remove the damaged tooth. Additionally, patients should pay attention to oral hygiene and can take some anti-inflammatory drugs orally to effectively control inflammation. Furthermore, during tooth extraction, it is crucial to pay attention to local hygiene, be mindful of food residue inside the mouth, eat and drink before the extraction, keep a relaxed mood, and follow the doctor's advice after extraction. Generally, do not eat for two hours after the surgery, do not brush your teeth or rinse your mouth within a day, avoid touching the wound, and manage your diet reasonably.

Can cavities spread to other teeth?

Cavities are a disease caused by bacterial infections of the hard tissues of the teeth, and they are infectious but not contagious. If cavities are not treated in a timely manner, the inflammation can further infect the dental nerves, causing nerve inflammation, and even lead to damage in the apical region of the tooth. Damage to the apical region of a tooth may also lead to damage in the apical region of adjacent teeth due to inflammation. This situation can spread to other teeth, but it is limited to the stage of apical inflammation. If it is just a simple cavity, where decay is confined to the crown area of a tooth, it will not spread to other teeth. Therefore, once a tooth decays, it is necessary to carry out dental filling treatment as soon as possible.
