Baby Tongue Thrust: What You Need to Know About

Published date field

When nursing babies with a breast or bottle, they may naturally poke out their tongues – but some parents are concerned about this behaviour. This is known as the tongue thrust reflex, which is normal in young infants and usually nothing to worry about. But if your son or daughter continues to poke out his or her tongue, or to show other signs of tongue thrust with age, it could be an early warning sign of dental problems.

What Is Baby Tongue Thrust?

Tongue thrust, found in infants, toddlers and young children, is associated with several different behaviours and conditions. Infant tongue thrust is a natural reflex that occurs when something touches a baby's lips.The baby's tongue comes out to help him suck from a breast or bottle, but it doesn't stay there when feeding time is over. In toddlers and children, tongue thrust occurs when the tongue is in an abnormal position, the mouth may be open when at rest, while the front teeth may protrude and speech may sound impeded. The condition may also indicate allergies, enlarged tonsils or adenoids. These reactions cause a constricted throat cavity, prompting the tongue to move forward and make breathing easier.

Tongue Thrust Effects

Tongue thrust isn't harmful in young babies and has no long-term effects, provided that the reflex goes away as your child gets older. Losing tongue thrust is a normal part of baby development and a sign that your baby is more prepared for weaning. Nonetheless, if the tongue remains forward in the mouth or pushes out when swallowing as he grows, the effects are fairly diverse. They can include poor teeth alignment and a lisp when speaking.

Time for Action

Consulting a dentist or paediatrician about tongue thrust is usually unnecessary for a young baby, but there are some signs you can look for in older babies. The symptoms of abnormal tongue thrust include the tongue resting in the wrong position, prolonged sucking, open resting lips and difficulty chewing food. It has also been highlighted that there are other signs as well, such as breathing through the mouth, oral sores and chapped, cracked lips from frequently licking them. If your older baby or toddler shows any of these signs, take him to see a dentist or paediatrician.

Losing Baby Tongue Thrust

Most babies lose baby tongue thrust reflex between four and six months of age. When food is placed on your baby's tongue or lips, the tongue doesn't come forward to push the food away, so he can take it in more easily. Losing the tongue thrust reflex ultimately means the baby is growing up and ready to start soft, pureed food. General dental health care should continue as normal, including regularly cleaning the teeth as soon as they erupt with a toothpaste specially formulated for infants aged 0-2 years.

Babies are precious, and it's natural to seek reassurance that behavior affecting their teeth, speech and eating is normal. Baby tongue thrust usually means your baby is healthy and developing well. If you have concerns, a paediatrician or dentist can conduct a gentle examination that puts your mind at ease.
