Dilaceration is an abnormal bend found on a tooth, and is nearly always associated with trauma that moves the developing tooth bud. As a tooth is forming, a force can move the tooth from its original position, leaving the rest of the tooth to form at an abnormal angle. Cysts or tumors adjacent to a tooth bud are forces known to cause ...
The incidence of neonatal teeth varies considerably, between 1:700 and 1:30,000 depending on the type of study; the highest prevalence is found in the only study that relies on personal examination of patients. [3] Natal teeth, and neonatal teeth, can be the baby's normal deciduous teeth, sprouting prematurely. [4]
A delay in tooth development may also serve as an indication, whereby the absence of an adult successor slows down the normal resorption of the roots of the baby teeth, which is the progressive loss of parts of the tooth. Misplaced (ectopic) positioning of the adult teeth may be discovered upon examination or a radiograph.
According to a recent study, baby teeth contain an abundance of stem cells, a very special type of cell that can potentially grow replacement tissue in the body and cure a number of diseases.
Typically, a parent may take a sick child to a traditional healer, who will look in the child's mouth and attribute the illness to "tooth worms".The healer will point out the small, white, developing tooth buds as being "tooth worms", and then dig the "worms" out of the gums without local anesthesia and using a non-sterile tool (normally a bicycle spoke).

Although tooth eruption occurs at different times for different people, a general eruption timeline exists. The tooth buds of baby teeth start to develop around 6 weeks of pregnancy. Adult teeth buds start forming around 4 months of pregnancy. The entire tooth will start to form from the crown down to the root. [8]
Discoloured teeth - teeth may be amber, brown, blue or opalescent; Bulbous shape to the tooth crown due to cervical constriction; Tooth wear/Non-carious tooth surface loss (NCTSL) - due to the poorly mineralised dentine, the enamel of the tooth is unsupported and subsequently shears or chips off as it is subjected to biting forces. This exposes ...
By targeting the USAG-1 gene, researchers believe that they can help people without a full set of teeth regrow teeth. The team says that humans have a third set of teeth available as buds, ready ...
