Understanding the Effects of Thumb-Sucking and Pacifiers

As parents, we always strive to ensure our kids’ oral health is in the best condition.

Today, we will discuss two common habits that can significantly impact your children’s oral health: pacifier use and thumb-sucking. Although these habits can comfort your child, they can have positive and negative effects on their oral health. Let’s find out.

Physical and social consequences

Altered facial and jaw structure

The constant sucking motion can lead to changes in the shape of the mouth, including a narrower palate and protruding front teeth. In some cases, the habit can cause a misaligned bite due to uneven growth of the upper and lower jaw.

Breathing complications

Children who suck their thumbs frequently (particularly beyond toddlerhood) may develop sleep apnea, a condition in which breathing stops and starts during sleep.

Incisor shift and misaligned teeth

The pressure of thumb-sucking on the teeth can cause the incisors to shift forward, leading to a misaligned bite. Over time, this can cause an open bite or overbite.

Speech

Thumb-sucking can cause the tongue to rest in an unnatural position. This can lead to difficulties with articulation and pronunciation.

Social interactions in preschool

Children who suck their thumbs may be teased or excluded by their peers, which can lead to feelings of isolation and low self-esteem.

Infection and rashes

The constant moisture and pressure of sucking the thumb can cause irritation and chapping, making the area more susceptible to bacterial or fungal infections.

Is it all bad? The advantages of thumb-sucking and pacifiers

While thumb-sucking and pacifier use is often associated with negative consequences, there are also some potential benefits to consider.

Thumb-sucking benefits

Self-soothing

Thumb-sucking can provide a sense of comfort and security, particularly in stressful or unfamiliar situations.

Pain relief

Thumb-sucking may also help to relieve pain, such as teething discomfort. The sucking motion can provide a distraction and release endorphins, which are natural painkillers.

Improved sleep

Some children may find it easier to fall asleep while sucking their thumb.

Independence

Thumb-sucking is a self-directed activity that can assert independence and autonomy for children.

Oral stimulation

Sucking on the thumb can provide oral stimulation, which is essential for oral motor development and can help to strengthen the muscles used for speech and swallowing.

Pacifier use benefits

Reduced risk of SIDS

Pacifier use has been linked to a reduced risk of SIDS (Sudden Infant Death Syndrome). While the exact mechanism is unclear, it may be related to the pacifier’s ability to keep the airway open and promote better breathing.

Easier weaning

Pacifiers are often easier to wean than thumb-sucking, as parents have more control over when and how the pacifier is used.

Reduced stress

Like thumb-sucking, pacifier use can be a way for children to self-soothe and regulate their emotions.

Oral stimulation

Pacifiers aid oral motor development by strengthening the muscles used for speech and swallowing.

Dental benefits

Pacifiers cause less pressure on the teeth, decreasing the likelihood of misaligned teeth and other dental damage.

The do’s and don’ts of helping your child kick the habit

Begin weaning a child off thumb-sucking and pacifier use between the ages of 2 and 4 years old. Keep in mind the following do’s and don’ts:

Do’s

Encourage your child’s efforts to stop sucking their thumb or pacifier by offering praise and positive reinforcement.

Start by limiting the time they spend sucking each day, and gradually decrease this time over a period of several weeks.

Provide your child with other forms of comfort and security. This could be their favourite stuffed animal or blanket to help them cope with the transition away from thumb-sucking or pacifier use.

Don’ts

Avoid punishing or shaming your child for their sucking habit. This can be counterproductive and may make the habit more difficult to break.

Do not use physical restraints, such as gloves or bandages, to prevent your child from sucking their thumb. This can be traumatic and may cause more harm than good.

Don’t push your child to stop before they are ready. It can make the habit more difficult to break for them.

 

Weaning your child off their thumb-sucking or pacifier habit may seem daunting, but it is essential to prevent dental problems and other complications. By following the recommended do’s and don’ts and taking a gradual approach, you can help your child successfully break the habit.

Remember to schedule your child’s first visit with a children’s dentist to ensure their oral health is in check.

Remember, it’s never too early to start building healthy dental habits that will benefit your child for a lifetime.
