Infants and preschoolers often suck their thumbs to calm themselves, a developmentally typical action <img src="https://p0.piqsels.com/preview/181/883/650/convenient-store-storefront-girl-short-hair.jpg" alt="u7121u6599u8857u89d2u306eu5199u771f | Piqsels" style="max-width:430px;float:right;padding:10px 0px 10px 10px;border:0px;"> The habit typically fades on its own before the age of four, leaving dental alignment unaffected However, persistent or forceful thumb sucking beyond this age can disrupt normal oral development The consistent pressure of the thumb against the palate and front teeth can reshape the dental arch Over time, children may develop an anterior open bite, preventing proper incisor contact It can also cause the upper incisors to protrude outward, creating a "buck tooth" appearance The upper jaw may constrict, limiting space for the tongue and altering its resting position Prolonged thumb sucking has been linked to speech impediments related to tongue placement The severity of these effects is greater when thumb sucking is aggressive or occurs for extended periods daily Passive thumb sucking_where the thumb rests gently without pressure_is rarely harmful to dental structure The transition to permanent dentition around age six is a key window for correcting thumb-sucking effects Without orthodontic treatment, structural changes caused by prolonged thumb sucking may become irreversible Families often seek guidance on the best strategies to discourage thumb sucking Praising children for not sucking their thumbs yields better results than criticism Offering stickers, small treats, or a progress chart can motivate children to reduce the behavior Dental appliances designed to block thumb access can be highly effective when behavioral methods fail This habit should never be met with shame, punishment, or negative reinforcement The majority of children abandon the practice naturally as they mature Positive parenting approaches make a measurable difference in preventing permanent damage Routine checkups with a pediatric dentist help monitor oral growth and <a href="http://woojincopolymer.co.kr/bbs/board.php?bo_table=free&wr_id=3038328">__ ____</a> catch problems early
