Top Five Things to Know About Thumb Sucking



Thumb sucking is a common behavior among infants and young children. It is a natural reflex that often starts in the womb and can continue well into childhood. While it may seem concerning to parents, thumb sucking is usually a harmless habit that children use to soothe themselves and cope with stress or anxiety.

Usually, thumb sucking goes away on its own

For most children, thumb sucking is a phase that they will outgrow on their own. Many children stop sucking their thumbs between the ages of two and four, often when they start attending preschool or kindergarten. However, some children may continue to suck their thumbs beyond this age, which can lead to dental problems if the habit persists.

If your child is still sucking their thumb after the age of four, it may be time to intervene. Gentle reminders and positive reinforcement can help encourage your child to stop. You can also try offering alternative comfort items, such as a stuffed animal or blanket, to help your child self-soothe without relying on their thumb.

Bite problems can result from persistent thumb sucking

While thumb sucking is generally harmless, persistent and vigorous thumb sucking can cause dental problems over time. When a child sucks their thumb, it puts pressure on the front teeth and can cause them to shift forward. This can lead to an overbite, where the upper teeth protrude over the lower teeth.

In addition to an overbite, thumb sucking can also cause other dental problems such as a narrow upper jaw, a high palate, and speech difficulties. These problems may require orthodontic treatment to correct, which can be costly and time-consuming.

Positive reinforcement can be employed to help break the habit

If your child is struggling to break the habit of thumb sucking, positive reinforcement can be an effective tool. Instead of scolding or punishing your child for sucking their thumb, try praising them when they refrain from the behavior.

You can also try setting up a reward system, where your child earns stickers or small prizes for not sucking their thumb. This can help motivate them to break the habit and give them a sense of accomplishment when they succeed.

It’s important to be patient and consistent when trying to break the habit of thumb sucking. It may take some time, but with positive reinforcement and support, most children are able to stop on their own.

Thumb sucking can be discouraged by a dental appliance

In some cases, a dental appliance may be necessary to help break the habit of thumb sucking. If your child is over the age of five and still sucking their thumb vigorously, your dentist may recommend a dental appliance called a thumb guard or palatal crib.

This appliance is a small metal device that is attached to the roof of the mouth. It makes it difficult for the child to suck their thumb and helps to break the habit over time. The appliance is usually worn for several months and can be an effective way to stop thumb sucking and prevent dental problems.

Ask your dentist for advice

If you’re concerned about your child’s thumb sucking habit, it’s important to talk to your dentist. They can assess your child’s dental health and recommend the best course of action to break the habit and prevent dental problems.

Your dentist can also provide guidance on how to encourage your child to stop thumb sucking and offer tips for making the process easier. They may recommend using bitter-tasting nail polish or thumb guards to discourage the behavior, or suggest ways to help your child cope with stress and anxiety without relying on thumb sucking.
