The thumb, the pacifier, the erupting tooth and a beautiful smile
Studies show that pacifiers are better for healthy dental development than thumb sucking.
The sucking reflex develops as early as the 29th week of pregnancy. Sucking is the first complex movement pattern with newborns. The natural need to suck is not completely satisfied by feeding and because of this, babies frequently suck their thumbs. The potential adverse effects of thumb sucking on the teeth and jaw are therefore the subject of numerous studies.
Baer and Lester performed a meta-analysis using studies that examined the sucking behaviour of children, showed the effects of thumb sucking and pacifiers or addressed the circumstances of teething.
