Thumb Sucking and Teeth: How This Habit Affects Dental Development

The thumb-sucking habit is a norm observed among infants and young children. It is a comforting activity often correlated with the child's sense of security. Extended thumb sucking may have dire consequences for dental development. In this blog, we shall address: thumb sucking and its effects on teeth, risks associated with thumb sucking, and ways to help a child break the habit. We will also elaborate on the orthodontic measures that can be taken to correct any existing problems caused by thumb sucking.

What is Thumb Sucking?

It is a natural reflex of sucking thumb for infants and toddlers. They suck thumbs to console themselves and self-soothe. This habit begins in the womb and usually continues after birth. Most children suck their thumbs only for one of these phases in life. Most children suck their thumbs between ages 2 and 4. However, some continue beyond that age, resulting in dental concerns.

Why Do Children Suck Their Thumbs?

Children will suck their thumbs because they bring them comfort, safety, and calmness in stressful situations. Thumb sucking can also soothe children to sleep. Continuation will be a result of learning habits or boredom. A normal habit in early childhood may become a problem with prolonged thumb sucking. It is recommended for parents to keep an eye on it and intervene when necessary.

How Thumb Sucking Affects Dental Development?

Such behavior has an impact on dental development because the pressure from sucking could change the shape of their mouths and teeth. Here are just a few common dental problems caused by prolonged thumb sucking:

1. Misaligned Teeth

Misaligned teeth are one of the most noticeable negative effects of thumb-sucking. The constant pressure could push the teeth from their proper position. This can lead to an overbite where the upper teeth protrude over the lower teeth. An open bite occurs when the upper and lower teeth do not meet when the mouth is closed.

2. Jaw Shape Change

Thumb sucking may affect the jaw growth. The habit can cause narrowing of the upper jaw, creating a crossbite. In crossbite, a few of the upper teeth sit inside the lower teeth. This misalignment can make chewing difficult and may also impact speech development.

3. Speech Problems

The dental problems caused by thumb sucking can lead to speech problems. Changing jaws and misaligned teeth can interfere with how a child articulates. The lisp, for instance, is a common speech problem faced by children born with tooth and jaw anomalies. Any delay in treating such type of issues may lead to long-term speech problems.

4. Roof of Mouth Changes

Thumb sucking can also alter the formation of the roof of the mouth or palate. The thumb pressure can raise and deform the palate. This can lead to breathing problems, and the alignment of the permanent teeth may also suffer.

5. Delayed Eruption of Permanent Teeth

Some believe thumb sucking can prevent the timely eruption of permanent teeth. This habit is said to interfere with the natural growth of the teeth. This delay can result in some spacing issues and abnormalities in proper teeth alignment.

How to Help Your Child To Stop Thumb Sucking?

Breaking the thumb-sucking habit in children can be challenging but parents have several effective options to help their children stop. Here is a list of some good methods:

1. Positive Reinforcement

Offer praise to your child for any attempt to stop thumb-sucking. Give rewards for avoiding thumb-sucking. Small rewards such as stickers or extra playtime will help motivate the child to quit.

2. Identify Triggers

Assist the child in identifying circumstances triggering thumb sucking. The most common incidents are boredom, stress, or tiredness. After identifying the triggers, find other ways to satisfy the craving. Engaging the child with comforting objects or hands-on activities can help keep them occupied and reduce thumb-sucking.

3. Utilize a Thumb Guard

A thumb guard is a structure that combats thumb sucking. It is protective of the thumb and prevents the child from sucking. A thumb guard is safe and effective in breaking the habit. Seek your dentist's advice for recommendations.

4. Calm Reminders

When you see your child sucking their thumb, gently remind them to stop. Scolding or punishing children for thumb-sucking will only increase their stress levels. Encourage your child and offer support to overcome their habit.

5. Referral to a Dentist

Consult with a dentist if the habit continues. Dentists can provide information on what to do next and offer treatment for any dental problems arising. Orthodontic appliances can sometimes be given to correct any alignment issues.

Orthodontic Solution for Existing Damage

When dental injury is caused because of thumb sucking, orthodontic treatment helps. Here are a few common orthodontic treatments through which damage caused by thumb sucking may be repaired:

1. Braces

Among common ways to treat misaligned teeth, braces involve gentle pressure on teeth to move their positions while correcting overbites, crossbites, and open bites due to thumb-sucking habits. Treatment duration varies depending on the severity of the issue.

2. Palatal Expanders

An appliance used to widen a narrow upper jaw is called a palatal expander. This device aids children whose narrow palate has been caused by thumb sucking, allowing the jaw to stretch gradually so that there can be more space for teeth to grow. In addition, it also improves breathing and alignment.

3. Clear Aligners

Another alternative to braces is clear aligners. These nearly invisible aligners are a convenient and effective option for both teenagers and adults. Clear aligners can treat very mild to moderate alignment issues.

4. Speech Therapy

If this habit has caused speech defects, speech therapy may be needed. A speech therapist can help children correct mispronunciations during sessions. Often, therapy is combined with orthodontic treatments for the best results.

Long-Term Effects of Thumb Sucking

Thumb sucking causes long-term dental health effects if left untreated. Orthodontic treatment may be required for misaligned teeth and jaw problems. If not corrected early, speech problems may last into adulthood. Changes in the roof of the mouth can result in breathing and sleep interference.

Preventing Dental Problems

It is important to take early action to prevent thumb-sucking-related dental problems in children. Parents should monitor the habit and help their child quit. Regular dental check-ups are essential for early problem detection. It is good to have an individual-appointed dentist who can give advice and treat the child.
