What is pulpitis?
Pulpitis is also an inflammatory reaction occurring in the pulp tissue, caused by the further infection of bacteria when tooth decay is not timely halted, and it represents the natural conclusion of tooth decay. The dental tissues are divided into enamel, dentin, cementum, and pulp tissue, with the pulp tissue located on the innermost side, which is commonly referred to as the dental nerve. If the bacterial infection is not promptly halted in the early stages within the hard tissues of the tooth, that is, if the tooth is not filled in time, the bacteria then further infect the innermost pulp tissue, causing inflammation of the pulp tissue, which is clinically referred to as pulpitis. Pulpitis involves severe pain, necessitating prompt root canal treatment for the tooth.
What to do after tooth extraction due to periodontitis?
After tooth extraction due to periodontitis, it is necessary to promptly fit a dental prosthesis. Periodontitis generally involves significant loss of the alveolar bone, leading to tooth mobility and even loss. After extracting a tooth due to periodontitis, it is essential first to observe for three months. After three months, once the absorption of the alveolar bone stabilizes, dental prosthesis can be performed. Temporary restorative measures, such as using temporary teeth, are also an option during this period. Temporary teeth generally require fitting with a permanent prosthesis after three months, at which point the temporary teeth are discarded. After fitting a permanent prosthesis, it is important to avoid hard foods since the jawbone conditions are not ideal due to periodontitis, and chewing hard objects could accelerate the absorption of the alveolar bone. Therefore, after tooth extraction due to periodontitis, temporary teeth can be worn for three months before permanent prosthetic treatment is carried out.
What department should I go to for periodontitis?
Patients with periodontitis should seek treatment in the periodontal department. If there is no periodontal department available, they can visit the department of oral medicine, or the department of stomatology or otolaryngology. Periodontitis is an inflammation of the periodontal support tissues, including gingivitis and periodontitis, with gingivitis being the early stage of periodontitis. It mainly occurs due to not brushing or rinsing promptly after eating, leading to the accumulation of food residues around the teeth. This condition requires timely teeth cleaning to remove these residues, otherwise, it could cause bleeding during brushing or eating and may further develop into periodontal pockets, leading to the appearance of periodontitis. Periodontitis might also involve the loss of alveolar bone support tissues, which requires timely dental cleaning followed by medication or a guided bone regeneration procedure.
Does periodontitis require root canal treatment?
Periodontitis is an inflammation of the tooth-supporting tissues caused by the lack of timely brushing and rinsing after eating, where food residues or soft plaque become calculus under the calcification of saliva. This condition requires tooth cleaning, which is a procedure performed around the teeth, and does not require root canal treatment. If periodontitis progresses further and bacteria from the periodontal pocket reach the root tip, it can cause inflammation around the tooth including the root tip. This may lead to a pathological condition of the dental nerve. If the root tip inflammation is caused by the retrograde action of periodontitis, root canal treatment is necessary because it affects the dental nerve. If there is no concurrent inflammation of the dental nerve, direct periodontal treatment can be performed. However, if retrograde root tip inflammation has occurred, then root canal treatment of the tooth is required.
Does pulpitis require hospitalization?
Pulpitis does not require hospitalization; it can be treated routinely in a dental outpatient clinic. Pulpitis results from the progression of caries. If dental caries are not addressed early with fillings, bacteria can infect further, reaching the dental nerves and causing symptoms of pulpitis. Severe pulpitis can cause pain when eating, pain at night, and poorly localized pain, which might radiate to the temporal area of the ear, causing intense discomfort. Routine outpatient treatments for pulpitis include nerve removal, anti-inflammation, and finally, root canal filling. A comprehensive root canal treatment can effectively resolve the symptoms of pulpitis, making hospitalization unnecessary.
Can pulpitis be treated by tooth extraction?
Pulpitis should not be treated by extraction. Pulpitis is simply a painful response caused by an infection of the pulp tissue and can be managed by preserving the tooth through root canal treatment. First, drill to remove the infected dental tissue, and when the dental nerve is exposed, apply a nerve-killing medication. After the nerve is destroyed, thoroughly remove the infected tissue, then seal the root canal, and after inflammation is controlled, fill the root canal. With treatment, it is possible to preserve teeth with pulpitis and extraction should not be performed. Removing a tooth during an active episode of pulpitis may lead to the systemic spread of inflammation.
Difference between oral ulcers and thrush
Oral ulcers and thrush are somewhat different. First, oral ulcers can occur in people of any age, but are more common in the elderly and children, mainly due to a low immune system. Thrush, on the other hand, commonly occurs in infants within the first six months after birth, mainly caused by an infection with Candida albicans. Clinically, oral ulcers may present with redness, swelling, and significant pain. Thrush is an infection by Candida albicans that occurs on the newborn's tongue, which may affect the infant's feeding, causing crying or refusal to eat. Generally, thrush is caused by an infection with Candida albicans and is a type of fungal infection, whereas most oral ulcers are due to poor nutrition or unbalanced nutrition.
What is periodontitis?
Periodontitis is an inflammation of the periodontal supporting tissues, including the gums, periodontal membrane, alveolar bone, and cementum. The early stages of periodontitis are mainly caused by irritants such as tartar, plaque, and soft deposits around the teeth, leading to swollen, pus-leaking gums, or bleeding during eating and brushing. If not treated promptly, tartar will adhere above and below the gums, forming supragingival and subgingival calculus. For calculus above the gums, ultrasonic cleaning, also known as dental scaling, is required. For calculus below the gums, it can be removed through curettage. If the mobility of the teeth improves after removal, the periodontitis can then enter the maintenance phase for the teeth.
Can you get your teeth cleaned during periodontitis?
Periodontitis is an inflammation of the supporting tissues around the teeth, commonly seen as gingivitis or periodontitis. In the early stages of gingivitis or periodontitis, dental calculus and soft plaque accumulate on the surface of the teeth, irritating the gum tissue and causing the gums to become red, suppurate, or even bleed. This condition requires prompt dental cleaning. Through ultrasonic oscillation, the dental calculus attached around the teeth is removed. If there is subgingival calculus, dental cleaning alone may not completely remove it, and subgingival scaling is also necessary, using specialized tools to manually remove the subgingival calculus.
Is bleeding when brushing teeth leukemia?
Bleeding during brushing is not necessarily leukemia; it could also be due to gingivitis or periodontitis. Bleeding can occur around the teeth where there are irritants like soft plaque or dental plaque. These irritants chronically stimulate the gingival tissues, causing them to be in a congested state. A stimulus, such as brushing, can then lead to bleeding of the gums. This condition is a common early sign of gingivitis or periodontitis. After dental cleaning to remove these irritants, followed by rinsing and medicating the area around the gums, the condition of gingivitis can be improved. Therefore, if bleeding during brushing can be improved through dental cleaning and medication, it indicates that the bleeding is simply caused by gingivitis or periodontitis, and not leukemia.
