Can pulpitis heal by itself?
Pulpitis can pathologically be divided into reversible pulpitis and irreversible pulpitis. Reversible pulpitis can sometimes heal on its own if external thermal stimuli are removed. Clinically, it may manifest as pain intensified by temperature stimuli, which disappears after the stimuli are removed. This condition can improve on its own with appropriate soothing treatment. If pulpitis progresses to irreversible pulpitis, it cannot heal on its own and requires prompt root canal treatment to alleviate the condition. If it worsens, it may lead to symptoms of apical periodontitis, hence root canal treatment needs to be performed as soon as possible for pulpitis.
Is a cavity the same as tooth decay?
Cavities, also known as dental caries, are a chronic progressive destructive disease caused by bacterial infection of the hard tissues of the teeth. Once a tooth is affected by a cavity, it is necessary to fill the tooth as soon as possible. Otherwise, the bacteria will further infect the tooth, causing inflammation of the dental nerve. Inflammation results in significant pain, including sensitivity to hot and cold, pain intensified by temperature changes, and even symptoms of nighttime pain. The most typical symptom of pulpitis is nighttime pain, which can wake someone from sleep. Therefore, once cavities occur, it is crucial to remove the decayed part of the tooth and fill it promptly to prevent potential tooth loss.
How many days will it take for oral ulcers to heal?
Oral ulcers are a common disease in the department of oral mucous membrane, prevalent among people of all ages, especially in children and the elderly who have lower resistance. If oral ulcers are caused by residues in the mouth or stimulation from sharp teeth edges, known as traumatic ulcers, it is necessary to promptly remove the irritants for the ulcers to heal. If the irritant factors are not removed, the oral ulcers will not improve, and severe cases may lead to cancerous changes. Generally, oral ulcers can heal on their own in about two weeks, or 14 days. If the ulcers do not heal after two weeks and keep recurring without improvement, one should be cautious about the possibility of cancer and further biopsy should be conducted for assessment.
Are mouth sores the same as oral ulcers?
Mouth sores, also known as oral ulcers, are a disease of the oral mucosa, which often occur when a person's immune system is weakened. When oral ulcers occur, the symptoms can include localized redness and pain in the mucous membranes, starting with redness followed by the onset of clinical pain. Oral ulcers generally heal on their own in about two weeks. There is also a condition commonly known as mouth sores, which, clinically speaking, is specifically herpetic stomatitis caused by herpes zoster virus infection. This is characterized by small white or yellowish bumps near the corners of the mouth, containing a yellowish fluid. This condition, also popularly referred to as mouth sores, is actually a disease resulting from herpes zoster virus infection of the oral mucosa.
How is pulpitis caused?
Pulpitis is generally caused by the progression of dental caries. Bacteria infect the hard tissues of the tooth, which is referred to as dental caries in the early stages. If the decayed parts are not removed in time for dental filling, meaning the teeth are not filled promptly, the bacteria will further infect the pulp tissue, leading to pulpitis. Pulpitis is actually the outcome of further bacterial development. However, if pulpitis is not treated in time, the inflammation can advance to the root apex, causing apical periodontitis. Therefore, pulpitis requires prompt endodontic treatment of the tooth. After controlling the inflammation, the root canal is filled. Following the filling of the root canal, the top of the tooth crown is sealed, which involves the filling of the tooth.
What department should I go to for periodontitis?
Periodontitis is an inflammatory reaction that occurs in the supporting tissues of the periodontium, commonly presenting as gingivitis or periodontitis in clinical settings. Gingivitis, the early stage of periodontitis, is caused by food residues left after eating, which calcify under the action of saliva to form tartar. This tartar further irritates and causes inflammation of the gingival or periodontal tissues. Initially, one should visit the ENT (Ear, Nose, and Throat) department for this condition. If the specialties are further divided, one can consult the oral medicine department under ENT. If oral medicine is further subdivided, a visit to the periodontal department is necessary. Therefore, for detailed treatment of periodontitis, it is advisable to visit the periodontology department within the oral specialties to undergo teeth cleaning followed by gingival medication to improve the symptoms of periodontitis.
Symptoms of tooth nerve pain
Symptoms of tooth nerve pain include pain triggered by cold, hot, sour, sweet stimuli, spontaneous pain, secondary pain, and nighttime pain, as well as unlocalized pain. These are also the main symptoms of pulpitis. Among them, pain triggered by cold, hot, sour, and sweet stimuli is more obvious. Sometimes the pain may intensify with temperature changes, such as cold and hot stimuli. If the pulpitis reaches the acute suppurative stage, there may also be pain that worsens with heat and is relieved by cold. It is common to see patients coming to the clinic holding cold water, indicating that cold water may provide temporary pain relief. In addition, severe nighttime pain might occur, where there is no pain during the day, but intense pain at night, sometimes making it difficult to sleep or waking from sleep due to the pain. Sometimes tooth nerve pain can also be unlocalized, potentially causing pain in the temporal area or affecting both upper and lower jaw teeth.
What should I do if I have gingivitis?
Gingivitis is characterized by symptoms such as bleeding while eating or brushing teeth. Sometimes, bloodstains may be found on the pillow upon waking up, which are also signs of gingivitis. Gingivitis can sometimes cause pain while eating, necessitating timely and thorough treatment, which includes both initial and maintenance phases. The initial treatment involves removing irritants around the teeth, including tartar, dental plaque, or soft deposits around the gums, followed by medicated rinsing. After controlling gingivitis, it is necessary to enter a regular maintenance phase with check-ups every six months, and any existing tartar should be promptly removed.
Can cavities be brushed with an electric toothbrush?
Cavities can be cleaned using an electric toothbrush. However, if the cavity is severe, the vibrations from the electric toothbrush may cause pain. It is necessary to fill or treat teeth with cavities as soon as possible. Only after treatment can the progression of the cavity be controlled; merely brushing with an electric toothbrush cannot control the development of the cavity. Cavities are a destructive disease caused by bacterial infection of the hard tissues of the teeth. Control over cavities can only be achieved by removing decay and using a drill to remove the infected cavity tissue; an electric toothbrush cannot control the development of cavities.
How many days does it usually take for oral ulcers to heal?
Oral ulcers occur on the mucous membranes of the mouth and are a common disease caused by low immunity, or a lack of vitamins and trace elements, leading to a mucosal disease of the mouth. Generally, oral ulcers can heal on their own in about 14 days, or two weeks. If the ulcers do not improve after two weeks, a biopsy is necessary to avoid potential malignancy. Oral ulcers may also be due to sharp tooth cusps or dental roots within the mouth, which are referred to as traumatic ulcers; these can be examined. If dental roots or other irritating factors are present near the ulcer, it is important to promptly remove these external irritants. Oral ulcers that do not heal on their own after two weeks require further biopsy.
