Can you get your teeth cleaned if you have cavities?
Cavities can also be treated with teeth cleaning. Firstly, a cavity is a type of dental caries, a tooth condition caused by tissue infection. Generally, it is accompanied by pain. Teeth cleaning is needed when there is a significant build-up of tartar around the teeth, which if not promptly cleaned, can lead to gingivitis and even periodontitis, potentially causing tooth loss. During cavities, teeth cleaning can be performed. However, teeth cleaning involves ultrasonic removal of tartar around the teeth. If the cavities are deep, the cleaning process may cause discomfort or severe pain. Therefore, it is necessary to treat the cavities first before proceeding with teeth cleaning to avoid significant pain during the cleaning process.
Can pulpitis be cured?
Pulpitis is a condition that arises from the further progression of dental caries, which is a defect in the hard tissues of a tooth caused by bacterial infection. If the caries is not treated in time to stop its further progression, bacteria will further infect and cause inflammation of the dental nerve, also known as the pulp tissue. The innermost part of a tooth contains the dental nerve, surrounded by hard dental bone and dentin. Therefore, once the dental nerve becomes inflamed, the pain can be very severe. However, pulpitis can improve after root canal treatment, meaning it is curable, but it requires root canal treatment of the tooth. If not treated promptly, it will not heal on its own. If pulpitis is not treated in time, it can further progress to form periapical abscess, and in severe cases, it can cause facial swelling.
The concept of dental caries
Cavities, also known as dental caries or tooth decay, are caused by bacterial infection that damages the hard tissues of the teeth. Once cavities occur, it is essential to intervene with dental treatment as soon as possible. Strictly speaking, cavities represent a bacterial infection caused by the failure to remove food residues timely after eating. Bacteria break down glucose, producing lactic acid, which causes demineralization of the teeth. Once cavities occur, it is crucial to undergo dental filling treatment promptly, commonly referred to as dental restoration. If the progression of decay is not promptly halted, it can lead to further complications over time, including pulpitis which causes toothache or night pain, pain during sleep intense enough to wake one from sleep, and in severe cases, facial swelling.
What should I do about trigeminal neuralgia of the teeth?
Trigeminal neuralgia in the teeth is generally caused by lesions in the areas controlled by the trigeminal nerve, leading to pain. This pain has trigger points, which could be a particular patch of skin or triggered during face washing, producing paroxysmal, electric shock-like pain. It is important to differentiate this from tooth-related nerve pain. Sometimes toothache may resemble symptoms of trigeminal neuralgia. If dental treatment does not relieve the pain, it might be trigeminal neuralgia related to the teeth. Trigeminal neuralgia requires medication, and there are many types of treatments available. If medicinal treatment proves ineffective, surgical treatment or acupuncture may be employed. In severe cases, nerve tissue blockage can be performed to temporarily relieve the pain.
What are the symptoms of periodontitis?
Periodontitis stems from the further development of gingivitis, sharing many symptoms, including gum redness, congestion, and pain when eating. Additionally, periodontitis can cause teeth to become loose, and in severe cases, lead to tooth loss. There is also the presence of a periodontal ligament condition. Generally, gingivitis corresponds to a pseudo periodontal ligament while periodontitis involves the actual periodontal ligament due to the resorption of the alveolar bone—this distinction is crucial in differentiating gingivitis from periodontitis. Periodontitis features true periodontal ligament formation concurrent with the resorption of the jawbone. Dietary precautions for periodontitis include avoiding hard foods and not chewing hard objects to prevent resorption of the alveolar bone in the root apex area.
Which department should I go to for oral ulcers?
Oral ulcers are manifestations of other diseases in the oral cavity and are not a singular oral disease. However, oral ulcers are primarily investigated in the department of stomatology, specifically within the oral mucosa department. Common causes of oral ulcers include a weakened immune system, which requires strengthening resistance through methods such as enhanced physical exercise or consuming more vegetables and fruits to increase vitamin intake. Oral ulcers may also be caused by irritation from dental calculus or tooth roots, categorizing them as traumatic ulcers, which necessitate the timely removal of irritating factors. Additionally, oral ulcers may be related to genetic factors or result from viral infections. Therefore, it is important first to identify the underlying cause for further investigation.
Do I go to the Department of Oral and Maxillofacial Surgery for pulpitis?
Pulpitis requires a visit to the department of stomatology or the department of dental cariology and endodontics. Some hospitals, with more detailed department divisions, differentiate between adults and children. Generally, individuals under 18 years old fall under the pediatric dentistry department. Those 18 and older need to visit the department of dental cariology and endodontics. Pulpitis is a painful condition caused by bacterial infection of the dental nerve, clinically manifested by pain when eating, night-time pain, localized pain, and worsening pain upon exposure to hot and cold stimuli. Treatment for pulpitis involves root canal therapy. This involves drilling to remove the infected dental tissue, then performing root canal medicament filling, followed by inflammation control and root canal filling.
What should I do about permanent tooth decay?
Permanent tooth decay refers to the decay that occurs in children's newly emerged permanent teeth or already replaced permanent teeth. Once decay occurs in a permanent tooth, it is necessary to fill the tooth as soon as possible. Decay is removed by drilling out the decayed hard tissue of the tooth. After removal, direct pulp capping treatment for the tooth is performed. If the decay in the permanent tooth is deep and has reached the tooth nerve, pulp treatment is needed. Vital pulpotomy can be used to retain the root pulp of the root part to promote further development of the tooth root. If the apex of the root has already formed in the permanent tooth and decay occurs, and the tooth nerve cannot be preserved, we can directly proceed with root canal treatment.
Can periodontitis be cured?
Periodontitis is a serious condition that develops if gingivitis is not treated promptly. Mild periodontitis can be cured. If periodontitis is detected early, it can be controlled by dental cleaning, removing dental plaque, food residues, tartar, or soft deposits around the teeth, and then rinsing and medicating the gum tissue. If periodontitis further progresses to cause partial absorption of the alveolar bone, this stage can also be treated by guided bone regeneration to cure periodontitis. If severe, with extensive absorption of the alveolar bone and significant loosening of the teeth, it is very difficult to cure.
Does periodontitis need treatment?
Gingivitis is an inflammatory reaction of the tissues surrounding the teeth, clinically manifested as gingivitis or periodontitis. Symptoms include bleeding while eating or brushing teeth. Periodontitis needs to be treated early and can be managed by dental cleaning to remove local irritative factors. Dental calculus is divided into supragingival calculus and subgingival calculus. Supragingival calculus can be removed by dental cleaning, while subgingival calculus requires subgingival scaling. Early treatment of periodontitis can preserve the teeth; if not treated promptly, periodontitis may further lead to the resorption of the alveolar bone, requiring tooth extraction in severe cases.
