When Does Thumb Sucking Become a Problem? A Guide for Parents
Many children give up thumb sucking on their own before they start preschool. For persistent thumb suckers, though, a little help may be needed to protect their growing smiles. At Middleburg Smiles, we often talk with parents in Middleburg, VA and across Loudoun County about thumb sucking and children's teeth, and the good news is that most kids can kick the habit with patience and encouragement.
Why Children Suck Their Thumbs
Thumb sucking is a natural reflex that helps calm, soothe, and lull babies and young children to sleep. In fact, it can begin even before birth. Most children drop the habit as they get older and learn other ways to handle their emotions. For some, though, the need to self-soothe lingers, and they keep sucking their thumb or using a pacifier.
When Should Thumb Sucking Stop?
According to the American Dental Association, children usually stop sucking their thumbs between ages two and four, or by the time their permanent front teeth are ready to come in. In most cases, thumb sucking isn't a cause for concern. How a child sucks matters, too. Children who rest a thumb gently in their mouth are less likely to have problems than those who suck vigorously. If the habit becomes constant or intense, or continues as the permanent teeth arrive, it may be time for professional guidance.
Can Thumb Sucking Affect Your Child's Teeth?
In a healthy bite, the top front teeth slightly overlap the bottom front teeth. Ongoing thumb sucking or pacifier use can keep these teeth from coming in fully or push them forward. This can create an open bite, a gap between the top and bottom front teeth even when the mouth is closed. An open bite can affect how a child chews and pronounces certain sounds.
If the habit isn't addressed early enough, orthodontic treatment or other dental care may be needed later to correct these changes.
How to Help Your Child Stop Thumb Sucking
Most of the time, the best strategy is to avoid making a big deal of it. If your child is older than four, or you notice signs of a shifting bite or a habit that seems hard for your child to control, mention it at their next dental visit. In the meantime, these ideas can help at home:
- Praise your child when they go without sucking their thumb or pacifier.
- If your child sucks their thumb when anxious, talk with them and calmly ask what's making them feel worried or upset.
- Offer a small reward when they reach a set amount of time without thumb sucking.
- Make it a game. Create a chart and add a gold star for each successful day so your child can see their progress.
When Professional Help Makes Sense
Sometimes, despite your best efforts, a little outside help is needed to break the cycle. Options include bitter-tasting coatings for the thumb and habit-deterring dental appliances. In the most persistent cases, a therapist or psychologist can help get to the root of what's driving the habit.
Whatever approach you choose, stick with positive reinforcement. Criticism, nagging, or scolding can make the habit worse and add to your child's anxiety. A loving, supportive environment, and plenty of reassurance that they're safe and loved, goes a long way.
