Thumb sucking often worries parents due to its possible effects on a child’s dental growth and social life. While most kids stop this habit by age five without harming their teeth or jaw structure, some continue beyond this age. For these children, steps must be taken to avoid lasting changes to the shape of their palate and the positioning of their jaws. Additionally, ongoing thumb sucking can lead to social difficulties, such as being teased by peers, potentially impacting their self-confidence.
There are several strategies parents can consider to help their children overcome this habit, but it is critical to understand that first the child has to want to stop the habit. The parent can then use a physical reminder — as explained here later — to remind the child when this often automatic habit of putting a finger or thumb in the mouth happens, so that it can be stopped.
One commonly used method involves applying a bitter or sour-tasting liquid to the child’s thumb or fingers. These products, readily available at drugstores, are akin to nail polish in their application. They aim to deter children from thumb sucking by making the experience unpleasant. While effective for some, this approach might not work for every child; some may adapt to or even come to like the taste, rendering the method ineffective. Regular application, typically nightly, is necessary for this strategy to have a chance at success.
Another option is the use of a thumb or finger guard, which is particularly useful at night. This device, a plastic casing that fits over the child’s thumb or finger, is secured with a wristband that the child cannot remove independently. This physical barrier can significantly reduce or eliminate the thumb sucking habit. The guard is designed for temporary use, with each unit coming with a supply of wristbands for continuous application over a specified period.
For cases where these initial interventions prove unsuccessful, dental professionals may recommend an Bluegrass Appliance. This device, which resembles a retainer, is fitted to the child’s teeth, changing the sensation of thumb or finger sucking. While it is a more intrusive solution, the appliance allows for normal speech and eating habits and is not easily visible, minimizing any potential for embarrassment. A key consideration with this appliance is the duration it remains in place—typically recommended for a minimum of 3-6 months to ensure the habit is adequately addressed. Parents are advised to keep the appliance after removal in case of a relapse, allowing for reapplication if necessary.
In summary, addressing prolonged thumb sucking requires a nuanced approach, with a range of interventions available to suit different children’s needs and responses. Whether through the application of taste deterrents, physical barriers, or dental appliances, the goal remains the same: to prevent the long-term dental and social consequences of this habit. Parents may need to experiment with different methods, sometimes in consultation with dental professionals, to find the most effective solution for their child.
