Why deciduous teeth are called milk teeth?
Everything you need to know about milk teeth Milk teeth, which are more formally called 'deciduous teeth' because of the way they are shed, develop when we are just mere embryos. They erupt in infancy – hence the moniker 'baby teeth' – and fall out during childhood, making the way for our permanent adult teeth.
Do deciduous canine teeth fall out?
As the adult teeth develop, they begin to exert pressure against the roots of the deciduous teeth, stimulating the roots of the deciduous teeth to begin resorbing. Once the roots have resorbed, the crowns of the deciduous teeth fall out.
When do canine teeth fall out?
The canines are usually lost between the ages of 9 and 12 years old, while the primary second molars are the last baby teeth that your child will lose. These final sets of teeth are usually shed between the ages of 10 and 12. As your child grows, their jaws also grow to accommodate the larger permanent teeth.
When should deciduous canines be removed?
A persistent deciduous tooth should be removed as soon as the crown of the permanent tooth is visible above the gingival margin. Early removal of persistent deciduous canine teeth may allow the erupting permanent teeth to move into normal occlusion (FIGURE 6).
Do puppy canine teeth fall out?

When do teeth form?
Formation. Primary teeth start to form during the embryonic phase of human life. The development of primary teeth starts at the sixth week of tooth development as the dental lamina. This process starts at the midline and then spreads back into the posterior region.
Why are primary teeth important?
The primary teeth are important for the development of the child's speech, for the child's smile and play a role in chewing of food , although children who have had their primary teeth removed (usually as a result of dental caries or dental injuries) can still eat and chew to a certain extent.
How do permanent teeth resorb?
The erupting permanent teeth cause root resorption, where the permanent teeth push on the roots of the primary teeth, causing the roots to be dissolved by odontoclasts (as well as surrounding alveolar bone by osteoclasts) and become absorbed by the forming permanent teeth. The process of shedding primary teeth and their replacement by permanent teeth is called tooth exfoliation. This may last from six to twelve years of age. By age thirteen, there usually are only permanent teeth remaining. However, it is not extremely rare for one or more primary teeth to be retained beyond this age, sometimes well into adulthood, often because its secondary tooth failed to develop.
What is the function of primary teeth?
The primary teeth maintain the arch length within the jaw, the bone and the permanent teeth replacements develop from the same tooth germs as the primary teeth. The primary teeth provide guidance for the eruption pathway of the permanent teeth.
How many teeth are there in each quadrant?
The primary teeth are made up of central incisors, lateral incisors, canines, first molars, and second molars; there is one in each quadrant, making a total of four of each tooth. All of these are gradually replaced by similarly named permanent counterparts except for the primary first and second molars; they are replaced by premolars .
What happens when permanent teeth erupt?
The erupting permanent teeth cause root resorption, where the permanent teeth push on the roots of the primary teeth, causing the roots to be dissolved by odontoclasts (as well as surrounding alveolar bone by osteoclasts) and become absorbed by the forming permanent teeth.

Teeth normally erupt in pairs and the first that normally come in are the lower central incisors. By the time your child is 2, he or she should have a full set of deciduous teeth.
Why do we need deciduous teeth?

What is the name of the cell that absorbs the roots of the baby teeth?
As the adult teeth (seccedaneous teeth) form, special cells called odontoclasts absorb the roots of the baby teeth, so that when your adult teeth start to emerge from your gums the deciduous teeth have no roots, making them loose and able to easily fall out.
Do deciduous teeth need to be cared for?

Do babies have cavities?
A gross misconception about baby teeth is that since they will eventually be replaced by primary teeth, there's no reason to take care of them. But cavities are a very real cause for concern -- even for deciduous teeth. Children who suffer from dental cavities in their baby teeth are more prone to cavities in their permanent teeth. And every dentist will agree that oral hygiene habits begin in childhood. So it is essential that you take excellent dental care of your little ones' baby teeth, as they won't be able to do so themselves for the first handful of years.

In each half of each jaw, beginning at the midline and extending backward, these teeth are called: central incisor, lateral incisor, cuspid, first molar, and second molar. See figure 4-2. The name for each tooth is made more specific by the addition of terms indicating its location within the mouth, such as maxillary (upper) left central incisor or mandibular (lower) right cuspid. Thus, there are four of each type of tooth. Each is individually designated as maxillary or mandibular and as right or left.

Overview
Deciduous teeth or primary teeth, also informally known as baby teeth, milk teeth, or temporary teeth, are the first set of teeth in the growth and development of humans and other diphyodonts, which include most mammals but not elephants, kangaroos, or manatees which are polyphyodonts. Deciduous teeth develop during the embryonic stage of development and erupt (break through the gums and become visible in the mouth) during infancy. They are usually lost and replaced by per…
Development
Primary teeth start to form during the embryonic phase of human life. The development of primary teeth starts at the sixth week of tooth development as the dental lamina. This process starts at the midline and then spreads back into the posterior region. By the time the embryo is eight weeks old, there are ten buds on the upper and lower arches that will eventually become the primary (deciduous) dentition. These teeth will continue to form until they erupt in the mouth. In the prima…
Function
Primary teeth are essential in the development of the mouth. The primary teeth maintain the arch length within the jaw, the bone and the permanent teeth replacements develop from the same tooth germs as the primary teeth. The primary teeth provide guidance for the eruption pathway of the permanent teeth. Also the muscles of the jaw and the formation of the jaw bones depend on the primary teeth to maintain proper spacing for permanent teeth. The roots of primary teeth provid…
Caries in deciduous teeth
Dental caries, also known as tooth decay, is one of the most prevalent chronic diseases among children worldwide. This oral condition involves bacterial infection which demineralizes and destructs tooth tissues. In primary dentition, extensive tooth decay is the most common dental disease. An extensive carious lesion affects at least half of a tooth and possibly involves the pulp.
Treatment for caries in deciduous teeth
Tooth decay in primary teeth tends to progress quite quickly and often reaches the pulp of the tooth. In cases of extensive tooth decay, the pulp must be treated to maintain the health of the tooth and its supporting tissues. In pulp therapy, areas of decay and infected pulp tissue are removed, then the pulp is sealed with medicaments.
Medicaments are medications placed over the pulp to maintain survival and promote repair. Tre…
Recommendations for medicaments used in pulp treatment
After direct pulp capping, it is unclear whether any one medicament is superior.
After pulpotomy, MTA is the most effective medicament and formocresol is also effective. Both are more effective than calcium hydroxide, which is more likely to fail. While there are concerns about the toxicity of formocresol, currently there are no reports of toxicity related to formocresol use for vital pulp therapies in children. An undesirable effect of treatment with MTA is the grey d…
Society and culture
In almost all European languages the primary teeth are called "baby teeth" or "milk teeth". In the United States and Canada, the term "baby teeth" is common. In some Asian countries they are referred to as "fall teeth" since they will eventually fall out.
Although shedding of a milk tooth is predominantly associated with positive emotions such as pride and joy by the majority of the children, socio-cultural factors (such as parental education, r…
