kids are unlikely to damage their teeth, jaw, or bite if they stop using a pacifier by the time they're 2 or 3 years old &#8211; and your child probably won't be at it for that long. During the years that most kids use a pacifier, they have only their&#160;<a href="https://www.babycenter.com/101_baby-teeth-order-of-appearance_10355502.bc">baby teeth</a>. (<a href="https://www.babycenter.com/0_your-childs-teething-and-tooth-loss-timeline_10356447.bc">Permanent teeth</a>&#160;typically start appearing by age 6.) That said, the longer your child uses a pacifier, the greater the chance it will affect dental development. If you ever become concerned about this, ask your child's doctor or dentist to make sure your child's jaw and teeth are doing fine. 
it used to be thought that babies who used a pacifier before they got the hang of nursing sometimes experienced&#160;<a href="https://www.babycenter.com/0_nipple-preference_8491.bc">nipple confusion</a>, which interfered with successful breastfeeding. But experts now say the research is conflicting, and there aren&#8217;t any studies that conclusively show whether the two are related. 
If you allow your child to use a pacifier but want to avoid binky battles, take it away when he reaches his first birthday. Being careful not to overuse the pacifier can help make sure your child doesn't become dependent on it.&#160;

pacifiers are not advisable...it can create nipple confusion, change the jawline shape etc....I had to use Pacifier for my daughter in 1st month as she was addicted to breastfeed and wanted to sleep like that... given her for few days but she herself rejected after 4-5 days....if situation is worst may be try taking the chance but buy the right one...I bought stage 1 from pigeon as per my pediatric and lactation counselor's advise

Most pediatrician do not suggest giving a pacifier. Try to avoid if possible
