History
Pacifiers were mentioned for the first time in medical literature in 1473, being described by German physician
Bartholomäus Metlinger
Bartholomäus Metlinger (born in Augsburg – died c. 1491) was a German physician of the Late Middle Ages.
Metlinger graduated in 1470 from the University of Bologna. He was city physician () in Nördlingen from 1476 to 1483, when he took t ...
in his book ''Kinderbüchlein'', in later editions retitled ''Regiment der jungen Kinder'' ("Caring For Young Children").
In England in the 17th–19th centuries, a ''coral'' was a teething toy made of coral, ivory or bone, often mounted in silver as the handle of a rattle. A museum curator has suggested that these substances were used as "sympathetic magic" and that the animal bone could symbolize animal strength to help the child cope with pain.
Pacifiers were a development of hard teething rings, but they were also a substitute for the softer ''
sugar tits'', ''sugar-teats'' or ''sugar-rags'' which had been in use in 19th century America. A writer in 1873 described a "sugar-teat" made from "a small piece of old linen" with a "spoonful of rather sandy sugar in the center of it", "gathered ... up into a little ball" with a thread tied tightly around it. Rags with foodstuffs tied inside were also given to babies in many parts of Northern Europe and elsewhere. In some places a lump of meat or fat was tied in cloth, and sometimes the rag was moistened with brandy. German-speaking areas might use ''Lutschbeutel'', cloth wrapped around sweetened bread or poppy-seeds.

Sears, Roebuck & Co. advertised a "new style rubber teething ring, with one hard and one soft nipple".
[ And in 1909 someone calling herself "Auntie Pacifier" wrote to the ''New York Times'' to warn of the "menace to health" (she meant dental health) of "the persistent, and, among poorer classes, the universal sucking of a rubber nipple sold as a 'pacifier'."

doctor complained about "the dummy teat": "If it falls on the floor it is rubbed momentarily on the mother's blouse or apron, lipped by the mother and replaced in the baby's mouth."
Early pacifiers were manufactured with a choice of black, maroon or white rubber, though the white rubber of the day contained a certain amount of lead. ''Binky'' (with a ''y'') was first used in about 1935 as a trademarked brand name for pacifiers and other baby products manufactured by the Binky Baby Products Company of New York. The brand name is currently owned by Playtex Products, LLC as a trademark in the U.S. (and a number of other countries).
Drawbacks
There are negative effects from using a pacifier during breastfeeding
Breastfeeding, or nursing, is the process by which human breast milk is fed to a child. Breast milk may be from the breast, or may be expressed by hand or pumped and fed to the infant. The World Health Organization (WHO) recommends that bre ...
for healthy babies. The AAP suggests avoiding pacifiers for the first month. Introducing a pacifier can lead to the infant ineffectively sucking at the breast and causing " nipple confusion". Babies will take their suck out on the pacifier instead of nursing or comfort nursing at the breast which is good for the mother's supply. Evidence in premature infants or infants that are not healthy is lacking but shows that it can have benefits. It may have clinical benefits for preterm babies, such as helping them progress from tube to bottle feeding.
Infants who use pacifiers may have more ear infections (otitis media

). The effectiveness of avoiding the use of a pacifier to prevent ear infections is not known.
Although it is commonly believed that using a pacifier will lead to dental problems, it does not appear to lead to long-term damage if used for less than around three years. However, prolonged use of a pacifier or other non-nutritive sucking habit (such as finger or blanket sucking) has been found to lead to malocclusion
In orthodontics, a malocclusion is a misalignment or incorrect relation between the teeth of the upper and lower dental arches when they approach each other as the jaws close. The English-language term dates from 1864; Edward Angle (1855-193 ...
of the teeth, that is teeth sticking out or not meeting properly when they bite together. This is a common problem and the dental ( orthodontic) treatment to correct it can take a long time and can be expensive.

(such as positive or negative reinforcement) were effective in helping children stop sucking habits where that was necessary. An orthodontic brace that used a palatal crib design seems to have been more effective than a palatal arch design.
There appears to be no strong evidence that using a pacifier delays speech development by preventing babies from practicing their speaking skills.
Benefits
Researchers have found that use of a pacifier is associated with a substantial reduction in the risk of sudden infant death syndrome
Sudden infant death syndrome (SIDS) is the sudden unexplained death of a child of less than one year of age. Diagnosis requires that the death remain unexplained even after a thorough autopsy and detailed death scene investigation. SIDS usuall ...
. They are divided over whether this association is sufficient reason to prefer pacifier use. Some argue that pacifiers should be recommended on the strength of an association, just as back sleeping was recommended on the strength of an association. Others argue that the association is not strong enough or that the mechanism is unclear.
Pacifiers have also been found to reduce infants' crying during painful procedures such as venipuncture.
Some parents prefer the use of a pacifier to the child sucking their thumb or fingers.
Researchers in Brazil have shown that neither "orthodontic" nor standard pacifiers prevent dental problems if children continue sucking past the age of three years.
It is commonly reported anecdotally that pacifier use among stimulant users helps reduce bruxism and thus prevents tooth damage. It is also known to help infants to get to sleep and also keeps infants calm.
Medical policies
The American Academy of Pediatric Dentistry's "Policy on Thumb, Finger and Pacifier Habits" says: "Most children stop sucking on thumbs, pacifiers or other objects on their own between 2 and 4 years of age. However, some children continue these habits over long periods of time. In these children, the upper front teeth may tip toward the lip or not come in properly. Frequent or intense habits over a prolonged period of time can affect the way the child's teeth bite together, as well as the growth of the jaws and bones that support the teeth."

(SIDS) states that "It seems appropriate to stop discouraging the use of pacifiers." The authors recommend the use of pacifiers at nap time and bedtime throughout the first year of life. For breastfeeding mothers, the authors suggest waiting until breastfeeding is well established, typically for several weeks, before introducing the pacifier.[
]
The British Dental Health Foundation recommends: "If you can, avoid using a dummy and discourage thumb sucking. With prolonged use (see Drawbacks above), these can both eventually cause problems with how the teeth grow and develop. And this may need treatment with a brace when the child gets older."
Prevalence of attachments to pacifiers and their psychological functions
In the late 1970s researchers dispelled the notion that pacifiers were psychologically unhealthy and aberrant. Richard H. Passman and Jane S. Halonen at the University of Wisconsin-Milwaukee traced the developmental course of attachments to pacifiers and provided norms. They found that 66% of their sample of babies who were three months old in the United States demonstrated at least some attachment, according to their mothers. At six months of age, this incidence was 40%, and at nine months it was 44%. Thereafter, the rate of attachment to pacifiers dropped precipitously until, at 24 months of age and later, it was quite rare.
These researchers also provided experimental support for what were then only anecdotal observations that pacifiers do indeed pacify babies. In an unfamiliar playroom, one-year-old infants accompanied by their pacifier evidenced more play and demonstrated less distress than did babies without them. The investigators concluded that pacifiers should be considered to be attachment objects, similar to other security objects like blankets.
Passman and Halonen contended that the widespread occurrence of attachments to pacifiers as well as their importance as security objects should reassure parents that they are a normal part of development for a majority of infants.
