The modern dentistry allows us avoid extracting teeth. Anyway sometimes it becomes necessary to extract the tooth.
Tooth extraction should be done in case of extreme necessity, when the other methods to maintain the tooth are useless or when the tooth can cause another serious disease.
Indications of tooth extraction
- Necessity of oral sanation when there is chronic periodontitis in its acute stage and it is impossible to eliminate the inflammatory nidus in the upper part of the tooth.
- Extraction of teeth that may cause vesicle, inflammation or neuritis of triple nerve,
- If the tooth harms the tongue or the buccal mucosa or impedes the right biting.
- Multi-root teeth that cause odontogenic osteomyelitis,
- If the tooth impedes the prosthesis placement,
- The teeth decayed because of caries that are impossible to restore
- Wrongly positioned teeth in the mouth cavity,
- Wisdom teeth.
Contraindications of teeth extraction
- Cardiovascular illnesses (hyperpressure, acute rheumatism, acute septic endocarditis, heart deficiency, arrhythmia, paroxysmal tachycardia)
- Kidney disease,
- Acute infection hepatitis,
- Acute leucosis, agranulocitosis,
- hemorrhagic diathesis,
- acute psychological illnesses,
- acute disorders of blood circulation in the brain,
- acute infections( flu, catarrhs of the upper respiratory tract),
- Purulent-inflammatory lesions (abscess, phlegmons in the maxillofacial zone, etc.)
- 1, 2, 9 months of pregnancy,
- Stomatitis ,
- Radiotherapy performed because of degeneration in the maxillofacial zone.
In a normal denture the teeth are in contact with each other and together take part in the process of mastication. During mastication the pressure reaches to several dozens of kilograms that is distributed equally in the denture. And if there is an extracted tooth the chain is interrupted and some teeth work overloaded, others underloaded. Besides derangement in the biting occurs as the position of neighboring teeth changes, they bend towards the low resistance; the teeth of the inverse jaw start elongating so as to fill the gap of the absent tooth. All this lead to different problems when placing prosthetics.
Summarizing we can say that the extraction of even one tooth is a serious problem that brings a chain of serious problems with time and to avoid complications the extracted tooth should be replaced with an artificial one.
