Dental caries
Does removing a cavity-affected tooth have any impact?
Cavities, also commonly referred to as tooth decay, can impact daily life depending on the situation. Generally, if the cavity is not severe, extraction is not necessary, and treatment should be attempted if possible. However, extraction can be harmful, as it creates a gap. The teeth adjacent to this gap can be affected, leading to tilting towards the gap or becoming loose, which may impact how the teeth come together when biting. The body has a protective mechanism that can automatically close this space, but although this closes the gap, it may destabilize the overall bite alignment and function, potentially affecting the temporomandibular joint function. Therefore, if tooth decay occurs, it is advised to seek prompt treatment at a formal dental hospital or a major hospital’s dental pulp department, where the decayed and necrotic tissue can be removed and the cavity filled to restore the shape of the tooth crown and some of the biting function.
If cavities that do not have holes are not filled, how will they develop?
In such cases, it is recommended that patients seek timely treatment at a dental clinic. Generally, the treatment might involve cleaning the area around the cavity. If the cavity is deep but not painful, a temporary filling with zinc oxide eugenol may be used. If there is no pain after about a week, a permanent filling can be placed, and root canal therapy may not be necessary. Specifically, it is best to go to the hospital for an X-ray to examine the condition properly. If there is food impaction in the teeth, it might indicate the presence of cavities. It is advisable for the patient to undergo some examinations to fill these cavities. Considering the sensitivity of the teeth, active treatment should be pursued.
Cavities that do not hurt still require root canal treatment.
Cavities that do not hurt may or may not require root canal treatment, depending on the extent of the decay. If the cavity has not reached the dental nerves, there will not be noticeable pain. In such cases, since the decay is relatively superficial, direct filling, or dental restoration can be performed without the need for root canal treatment. If the cavity is severe and has reached the dental nerves, causing the nerves to become necrotic and purulent, there will be no pain due to the loss of sensory function from nerve death. In these situations, root canal treatment is needed. This involves removing the infected dental nerves, followed by medicinal treatment of the root canal, and after the inflammation is controlled, filling of the root canal is performed. In other words, a painless cavity might actually be caused by necrosis and pus formation in the dental nerves, requiring root canal treatment.
Can you ignore a cavity if it doesn't hurt?
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.
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.
What will happen if a cavity is filled without being cleaned properly?
If tooth decay is not completely cleaned out before filling, bacteria can continue to develop and multiply within the tooth, leading to more severe decay and potentially causing diseases such as pulpitis or periapical periodontitis. It is recommended that patients with cavities should undergo treatment based on the severity of the decay. Mild cavities usually only cause minor changes in tooth color; this can be gently abraded and then treated with fluoride materials. If the cavity is more severe, the decayed material inside the cavity should be completely removed, and then light-cured resin material can be used for filling. Deeper cavities may also require a protective pulp base.
If a cavity doesn't hurt, is it better not to treat it?
Cavities are primarily caused by poor oral hygiene and the effects of bacteria in the mouth, among other factors, leading to chronic progressive destruction of the hard tissues of the teeth. Generally, the progression is slow, initially appearing as yellowish-brown spots or defects on the tooth surface without causing any pain symptoms, making the treatment fairly straightforward—simply removing the decay and filling it can often be completed in one session. However, many cavities are not treated during this optimal period and progress to the dentin, causing sensitivity to hot and cold and leading to toothache. If not treated promptly, the cavity will enlarge, and in severe cases, lead to pulp infection, causing spontaneous pain, episodic pain, and pain from temperature stimuli. At this stage, the treatment becomes more complex and painful, requiring root canal therapy, typically needing three to four follow-up visits, and thus, costing more than a simple one-time treatment. If the condition is not controlled, it may develop into apical periodontitis or apical abscess, leading to space infections. The treatment then becomes even more complicated and painful, requiring incision and drainage, along with systemic anti-inflammatory treatment. If the tooth is severely damaged, the remaining roots and crowns can become a focal point for bacterial infection, potentially inducing other diseases. Therefore, it is crucial to detect and treat cavities early—the smaller the cavity, the better the treatment outcome, also saving time and money.
Is tooth decay a contagious disease?
Cavities occur due to a large amount of dental plaque and tartar on the teeth, which erodes the teeth over time, causing damage to the enamel and dentin. This results in the appearance of black spots, black patches, and cavities. However, cavities are not contagious because there are always a large number of bacteria in the mouth due to eating and other reasons, so it is important to develop good brushing habits and the correct technique. Although brushing can remove some dental plaque, its effect is limited. It is best to undergo dental and gum cleaning treatments to significantly improve the removal of dental plaque and eliminate the harm of cavities to the human body.
Will tooth decay affect other teeth?
When a patient suffers from tooth decay, generally not taking measures to treat it may cause other teeth to also develop cavities. Some patients with long-term cavities may have one or more teeth affected, and even some patients might have entire teeth significantly decayed. Therefore, when cavities occur, certain measures must be taken for treatment. Depending on the condition of the cavity, a specific treatment plan should be formulated, whether it's a dental filling or tooth extraction. Thus, patients must pay attention to oral hygiene in their daily lives, brushing their teeth morning and evening. After meals, it's important to promptly remove food residues from the mouth and develop proper habits for brushing and eating. If a cavity develops, the patient should treat it early to prevent it from affecting other teeth.
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.
