However based on the usual eruption sequence of teeth, deciduous canines are extracted at the age of 8–9 years to create space for proper alignment of incisors, followed by extraction of deciduous first molars a year later so that the eruption of first premolars is accelerated and lastly extraction of the erupting first premolars to give ...
Once the periodontal ligament is broken and the supporting alveolar bone has been adequately widened the tooth can be removed. Typically, when teeth are removed with forceps, slow, steady pressure is applied with controlled force. Molar cut up during surgical extraction - the curvature of the three roots (top right) prevented simple extraction
Mixed dentition starts when the first permanent molar appears in the mouth, usually at six years, and lasts until the last primary tooth is lost, usually at eleven or twelve years. [47] Permanent teeth in the maxilla erupt in a different order from permanent teeth on the mandible.
The first human teeth to appear, the deciduous (primary) teeth (also known as baby or milk teeth), erupt into the mouth from around 6 months until 2 years of age, in a process known as "teething". These teeth are the only ones in the mouth until a person is about 6 years old creating the primary dentition stage.
This may involve having fixed or removable appliances for a few months before the transplant is done. [10] Occasionally the tooth to be transplanted will need to be removed before there is enough space available at the donor site. [10] These teeth can be kept in liquid nitrogen until pre-surgical orthodontic treatment is completed. [10]
Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth that is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion and are generally done when the cavity's too big ...

Modeled after a door key, the dental key was used by first inserting the instrument horizontally into the mouth, then its "claw" would be tightened over a tooth. The instrument was rotated to loosen the tooth. This often resulted in the tooth breaking, causing jaw fractures and soft tissue damage. The design of the dental key evolved over the ...
