Most teeth fall out spontaneously around 1-3 months of age, with some infants experiencing delays. Equine teeth, also known as “slats”, are a specific physiological manifestation of the newborn period, not a disease, and not contagious. The cause is not known, but is generally thought to be related to self-development or inflammation. The main manifestation is the appearance of yellowish-white granules above the gingival surface, with a relatively smooth surface and no obvious redness or swelling of the surrounding mucosa, at the location of the midline or gingival edge of the upper jaw of the infant. Most equine teeth can fade naturally after 1-3 months without special treatment and usually leave no sequelae. Some infants may have delayed loss of teeth, and usually no special treatment is needed. As the baby’s teeth grow and develop, the horse teeth will be absorbed or fall out automatically. It is recommended that if the baby has horse teeth, do not pick them or wipe them with force; breastfeeding should pay attention to the cleanliness of the nipple, bottle feeding should pay attention to the disinfection of the teat and bottle.
