Thumb Sucking and Prevention • Florissant

Digit sucking is a habit that occurs in infants. Children usually give up digit sucking by the age of four. If the child continues past the age when their permanent teeth start to erupt, they may develop crooked teeth and have a narrowed appearance to the roof of their mouth. This results from the frequency, duration, intensity, and position of the digit in the child’s mouth. This can also affect the position of the upper and lower jaw and can also affect speech.

Habit Appliances

Customized Thumb/Finger Appliances can be placed in the child’s mouth to prevent/deter the child from causing a deleterious effect on the developing dentition. They are very effective when left in place for 3-6 months. They are inserted using dental cement and will be removed by the pediatric dentist once the habit has been broken.

Suggestions to break the habit:

• Wait till the time is right (low stress).
• Motivate your child (show examples of what could happen to their teeth and fingers/thumbs).
• Use a reward system (small incentives will encourage your child to stick with it).

Frequently Asked Questions for Thumb Sucking:

1. Why do children suck their thumbs?

Thumb sucking is a common and instinctive behavior in infants and toddlers. It’s a self-soothing mechanism that helps them feel comforted and secure, especially when they’re tired, anxious, or seeking reassurance. While thumb sucking is natural in early childhood, it’s important to monitor the behavior as it can impact oral health if prolonged.

2. At what age should a child stop sucking their thumb?

Most children naturally stop sucking their thumbs by the age of 2 to 4. However, if thumb sucking continues beyond age 4, it can start to affect dental development. Prolonged thumb sucking can cause alignment issues with the teeth and may even alter the growth of the jaw. As a pediatric dentist, I recommend addressing the habit before age 5 to prevent long-term dental concerns.

3. Can thumb sucking cause dental problems?

Yes, prolonged thumb sucking can lead to dental problems, especially if it continues beyond age 4. It can cause an open bite (where the upper and lower teeth don’t touch), misalignment of the front teeth, and changes in the roof of the mouth. The pressure from thumb sucking can also affect the normal growth of the jaw and teeth. If the habit persists, our pediatric dentists can assess the risk and suggest solutions.

4. How can I help my child stop sucking their thumb?

Helping a child stop thumb sucking often involves a combination of gentle encouragement and positive reinforcement. Redirecting their attention with comfort items, such as a stuffed animal or a blanket, can be effective. For older children, using a reward system or discussing the consequences of prolonged thumb sucking on their teeth can motivate them to stop. If the habit persists or is causing dental issues, our pediatric dentists may recommend more tailored strategies, such as behavior modification techniques or using dental appliances.

5. Is thumb sucking harmful to my child’s health?

In the early stages, thumb sucking is generally harmless. However, if it continues beyond the age of 4 or 5, it can lead to dental concerns, such as misaligned teeth, changes in the roof of the mouth, and difficulties with bite development. Additionally, it may affect speech development and cause thumb-related injuries. If you’re concerned about the duration or intensity of your child’s thumb sucking, our pediatric dentists can evaluate your child’s oral health and provide guidance on how to address the habit before it leads to more significant issues.
