A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments ( dental drills ) to prepare the tooth and can be performed in settings with no access to dental equipment.
The inferior alveolar nerve block is probably one of the most common methods used by dentist to anaesthetise the mandibular teeth in adults. This technique aims to inject the needle and deposit local anaesthetic close to the nerve before it enters the mandibular foramen, which locates on the medial aspect of the mandibular ramus.
Non-dental sources of pain often cause multiple teeth to hurt and have an epicenter that is either above or below the jaws. For instance, cardiac pain (which can make the bottom teeth hurt) usually radiates up from the chest and neck, and sinusitis (which can make the back top teeth hurt) is worsened by bending over.
Tooth loss is a process in which one or more teeth come loose and fall out. Tooth loss is normal for deciduous teeth (baby teeth) , when they are replaced by a person's adult teeth . Otherwise, losing teeth is undesirable and is the result of injury or disease, such as dental avulsion , tooth decay , and gum disease .
As primary teeth are being developed, the ingestion of fluoride causes the teeth to form stronger and more resistant to cavities, although this increases the risk of dental fluorosis. [10] [11] [12] Water and milk fluoridation are two forms of systemic fluoride therapy that are effective at preventing dental cavities. [13]
It's important to understand why teens use or misuse drugs, so the right resources and education can help them, Dr. Nora Volkow, director of the National Institute on Drug Abuse, wrote in an email.
Fixed appliances may be used, for example, to rotate teeth if they do not fit the arch shape of the other teeth in the mouth, to adjust multiple teeth to different places, to change the tooth angle of teeth, or to change the position of a tooth's root. This treatment course is not preferred where a patient has poor oral hygiene, as ...
