Finger habits usually occur in infants. For some infants, the potential exists for thumb or finger-sucking habits to start in the womb.Â
What Are the Risks Posed by Thumb-Sucking?
The American Dental Association recommends that children stop sucking their thumbs by age four at the very latest. Failure to break the habit by age four can lead to poor oral health and significant orthodontic issues. They may develop crooked teeth, crossbites, a malformed roof of their mouth, and severe problems that affect jaw development resulting in overbites and anterior open bites. The severity of the problems depends upon the frequency, duration, intensity, and position of the finger in the child’s mouth. This can also affect the position of the upper and lower jaw resulting in speech impediments.
Breaking The Habit
Suggestions to break the habit of thumb sucking:
- Always be supportive and positive. Instead of punishing your child for thumb-sucking, give praise when he or she doesn’t.
- Put a band-aid on your child’s thumb or a sock over the hand at night or when watching TV. Let your little one know that this is not a punishment, but rather a way to help them remember to avoid sucking.
- Start a progress chart and let your child put a sticker up every day that he or she doesn’t suck. If your child makes it through a week without sucking, reward them with a predetermined prize. When the whole month is full, reward your child again with something great (a toy or a new video game); by then the habit should be over. Making your child an active participant in his or her treatment will increase the willingness to break the habit.
- If you notice your child sucking when he or she is anxious, work on alleviating the anxiety rather than focusing on the thumb sucking.
- Take note of the times your child tends to suck (long car rides, while watching TV and movies) and create diversions during these occasions.
- Explain clearly what might happen to the teeth if he or she keeps thumb-sucking.Â
- In some cases, a blanket or stuffed animal goes hand in hand with the habit. It may require eliminating both habits at the same time to be successful.
When Should You Talk to a Dentist About Finger Habits?

Frequently Asked Questions
Thumb and finger-sucking are common during early childhood, and many parents have questions about when to be concerned and what steps to take. Below are answers to questions families in San Diego often ask when it comes to finger habits and their child’s oral development.
Is thumb-sucking normal for toddlers?
Yes, thumb-sucking is completely normal in infants and toddlers. It is a natural self-soothing behavior that helps children feel secure. Most children naturally outgrow the habit on their own between ages 2 and 4.
Can thumb-sucking cause the need for braces later?
Prolonged thumb or finger-sucking can increase the likelihood of orthodontic issues, especially if the habit continues after permanent teeth begin to come in. Early dental monitoring helps determine whether the habit is affecting bite development and whether future orthodontic treatment may be needed.
Should I be worried if my child only sucks their thumb at night?
Nighttime thumb-sucking can still impact tooth and jaw development if it happens consistently over time. Even if it seems limited to sleep, it’s helpful to mention it during routine dental visits so your dentist can monitor any changes.
Are there dental appliances that help stop thumb-sucking?
In some cases, if the habit persists and is affecting development, a pediatric dentist may recommend a gentle habit appliance. These are only considered when other behavioral strategies have not worked and when the habit is causing noticeable dental changes.
How do I know if thumb-sucking is affecting my child’s speech?
Changes in jaw position or bite alignment from prolonged thumb-sucking can sometimes influence speech patterns. If you notice lisping or difficulty pronouncing certain sounds, it’s worth discussing with your pediatric dentist and, if needed, a speech specialist.
