One of the common questions we get here at Sandia Pediatric Dentistry is “is my child’s thumb sucking a problem?” Thumb or finger sucking is a common habit for infants and young children and is usually not something to be worried about unless the habit persists or it begins to cause problems with oral development. Pediatric Dentists are specially trained to recognize issues with oral development and can offer suggestions for how to avoid such problems.

Is thumb sucking normal?
Thumb sucking is common and normal. In fact, it is such a natural behavior that babies are often discovered sucking their thumbs in utero. Infants’ natural reflexes cause them to suck on objects placed in their mouths, and may include other fingers, blankets, or pacifiers. This behavior can provide comfort and soothe anxieties, which explains how thumb sucking can develop into a habit long after infancy. It is estimated that 30% of all children will suck their thumb during infancy. Positive emotional development and peer pressure generally end thumb sucking before kindergarten, however some children will continue the habit which can lead to dental problems.
When is thumb sucking a problem?
Dental issues can occur if thumb sucking continues after permanent teeth erupt or especially in cases of excessive sucking. Your child’s palate (the roof of the mouth) may become arched, causing what is known as an ‘Open Bite’. It may also cause front teeth to be pushed forward, causing bite and speech problems. Many older children who continue to suck their thumb may have difficulty articulating “S” sounds or sounds requiring the tongue to touch the front teeth. Some children develop chapped skin or worn fingernails on the thumb or finger being sucked. After age 5, or when permanent teeth are starting to erupt, it is a good idea to encourage the child to stop the habit.
How can I help my child stop thumb sucking?
Children usually stop sucking their thumb during their toddler years, but some will continue the behavior as a comfort process. Authorities in Pediatric Dentistry have found that the best methods to limit thumb sucking are based on positive reinforcement. Here are a few ideas to consider:
- A good first-step may be to merely ignore the behavior, especially if it is part of a power struggle with your child or it is being used to gain attention. Some experts suggest a one month break from discussing the subject before moving on to other means.
- Use praise when your child isn’t sucking his or her thumb, and never scold them when they do.
- Try positive reinforcement such as a sticker chart or other reward system.
- Seek out the possible causes of anxiety and work to alleviate the reasons for thumb sucking.
- Some children suck their thumbs from boredom. Try engaging your child in a fun activity.
- Allow older children to earn a reward for not sucking their thumb.
- Mention the behavior at your child’s next dental appointment and allow Dr. Sjostrom to offer some positive motivation.
- Place a bandage, sock or custom thumb guard on your child’s hand at night to discourage thumb sucking while sleeping.
