Thumb Sucking

Infants typically begin sucking their thumbs before they are born. Babies and toddlers typically quit sucking their thumbs on their own. Thumb sucking, on the other hand, might cause issues with children’s growing teeth and jaws if they continue to do so as their adult teeth are coming in.

Why are newborns and kids sucking their thumbs?

This reaction can evolve into thumb sucking or sucking other fingers in certain newborns and toddlers, which is a natural and calming behaviour for young children. It can assist kids in self-soothing, feeling safe, and falling asleep.

Between the ages of 2 and 4, most kids cease sucking their thumbs spontaneously, and by the age of 8, just about 1 in every 20 children sucks their thumb.

Pacifiers have the same effects on teeth as sucking fingers and thumbs, although they are generally simpler to break.

The amount of sucking impacts whether or not tooth issues develop. Children who passively lay their thumbs in their lips have less difficulties than those who suck their thumbs furiously. Some thumb suckers may experience difficulties with their baby (primary) teeth as a result of their aggressiveness.

What Age Should Kids Stop Sucking Their Thumbs?

Between the ages of two and four years old, or when the permanent front teeth are ready to sprout, children normally cease sucking. Consult your dentist if you observe any changes in your child’s primary teeth or are worried about thumb sucking.

What can be done about it?

Try these strategies if your toddler’s thumb sucking is still going strong at four years old, or if it’s beginning to interfere with speech or social skills at a younger age.

Open Bite

Thumb sucking’s most significant long-term consequences are various forms of dental malocclusion. When the mouth is closed, malocclusion is a categorical word that indicates dental misalignment that is evident. The open bite and overbite, which we’ll examine in the next section, are two of the most prevalent malocclusions induced by thumb sucking.

When the top and bottom front teeth are pointed outward, it is called an open bite. Even when your child’s mouth is entirely closed, the front teeth do not contact due to this misalignment.

In the future, an open bite may demand orthodontic therapy, or it may exacerbate other tooth misalignments that require orthodontic treatment.

Acting maturely is a must

Praise her frequently for “big-girl” behaviour (such as dressing herself or taking her dish to the sink) to encourage her to give up other little-kid behaviours, such as you-know-what.

Aside from that, keep your hands and lips busy

Encourage children to participate in hands-on activities like swinging, driving a toy, or playing with clay. To divert her attention away from her favorite finger, you may engage her in a chat-fest, sing songs together, or play with musical instruments.

Use incentives to keep people motivated

She’s mature enough to appreciate the power of incentives if she’s at least three years old. If she makes an attempt to quit, promise her a special reward. (You can give her stars for not sucking her thumb at normal thumb-loving moments and reward her when she achieves her objective; or give her little goodies at the conclusion of each thumb-free day.) When she feels the impulse to suck, teach her to create a fist with her thumb inside.

Provide Earlier Sucking Alternatives

Rather of pacifying a baby with a high sucking desire, consider other ways. Consider doing things like rocking, getting a massage, playing video games, or singing. The earlier a baby learns that there are alternatives to the breast, bottle, thumb, or pacifier for comfort, the more he will seek them later.

Keep Thumbs Busy

When there’s nothing else to do, bored tiny thumbs turn to their best buddy, the mouth. The bored child is kept occupied with various activities. Distract and divert the youngster into an activity that keeps both hands occupied when you notice the thumb travelling toward the mouth.

Maintain a calm demeanor

Your child will use his thumb to help him relax as he grows older. This is fantastic. You then try your best to maintain a pleasant environment at home. When you are worried, model soothing behaviours for your kid, such as quiet moments, long walks, music, and slow, deep breathing.

What are the options for treating thumb-sucking?

Most youngsters quit sucking their thumbs with simple home therapy procedures. Schedule an appointment with your kid’s doctor or dentist if your youngster develops a sucking habit at age 4 or older.

Parents establish restrictions and provide distractions at home as part of treatment. Limiting when and where your kid can suck his or her thumb, as well as putting away blankets or other objects your child identifies with thumb-sucking, may be beneficial. Putting gloves on your child’s hands or covering the thumb in an adhesive bandage or cloth might assist your youngster remember not to suck the thumb.

Praise, positive attention, and prizes for not thumb-sucking may also help your youngster quit. Put a sticker on a calendar for every day your child does not suck his or her thumb, for example. Have a party for your child when a certain number of days has passed.

If your child is thumb-sucking, don’t humiliate or scold them. Your child’s self-esteem will suffer as a result.

If home therapy fails and you’re concerned or upset about your child’s thumb-sucking, speak with his or her doctor. Other treatments may be available, such as behavioral counselling, thumb devices, or mouth devices.

Keep in mind, though, that thumb-sucking isn’t frequently an issue with preschoolers or younger children. If you give them enough time, most kids will quit on their own.
