It’s not unusual for children to pick up harmful oral habits at some point.

What makes pacifiers and thumb-sucking so bad?
Pacifiers and thumb-sucking are very common habits in young children, and thankfully they don’t always lead to damage to the teeth and mouth. While passively holding the thumb or pacifier in the mouth isn’t anything to worry about, active sucking can damage your child’s baby teeth. In many cases, these issues will resolve when the permanent teeth erupt, but more serious habits can cause damage to the permanent teeth as well.
The consistent motion of pacifier and thumb-sucking places pressure on the teeth, jaw, and roof of the mouth that can result in serious oral issues, including:
- Overbite – the front teeth protrude out over the jaw and mouth
- Open Bite – the top and bottom teeth don’t meet when the mouth is closed
- Change in jaw shape can cause alignment issues or speech problems
- Sensitivity in the roof of the mouth
If your child’s habit is resolved before the permanent teeth erupt, they likely won’t experience any long-term problems. However, if they continue to suck their thumb, these problems could develop and become more serious.
How to help your child break the habit
There are a few factors to consider when determining the best method to help your child break their bad habit. The most important is their age. For older children, simply talking to them about the problem can be beneficial. Noticing when and where the behavior occurs is another important aspect of breaking the habit. For example, if your child sucks their thumb as a self-soothing strategy, determine the root cause of that anxiety. If they do it when bored, help them by providing an activity with their hands instead.
Here are some additional ways to help kick this harmful habit!
Habit breaking appliance
Habit-breaking appliances help children eliminate bad habits and ensure a healthy smile. These specialized appliances are either fixed or removable and are placed on the roof of the mouth. They’re minimally invasive and provide a deterrent to pacifiers and thumb-sucking. Since the thumb or paci can’t comfortably apply pressure on the roof of the mouth, the benefits of thumb sucking won’t be present, and your child will eventually stop the habit.
If a habit appliance is necessary, your child may experience slight discomfort while adjusting. We suggest sticking to a soft diet during this time to avoid any additional discomfort.
Positive reinforcement
Encouraging your child when they aren’t engaging in pacifier or thumb-sucking can play a large part in their success! Tracking days without thumb-sucking with a fun chart can help your child see their progress and help you keep track, as well.
Thumb shields/gloves
These are a great way to remind your child not to suck their thumb throughout the day. They’re great for older children during the day when you can’t be there to remind them. You can also have your child wear gloves or mittens at night to prevent them from sucking their thumb while they sleep.
