How to Prevent Teenagers From Chewing on Their Sleeves
Chewing on things such as pencils or fingernails is a nervous habit that is a response to stress or anxiety. It could also fulfill a need for fidgeting. School and social pressures might be factors that influence sleeve chewing. Shirt sleeves are an easy target for this habit as they are within reach, are available at all times and aren't painful to the teeth.
Instructions
Talk to your teenager and ask him if something is bothering him. If the problem is a simple one, eliminating the source of anxiety will eliminate the need to chew. If it is stress about grades or dating or similar on-going issues, talking may not be enough to stop the worry. Give them something else to chew, for example, a string friendship bracelet. It has a similar feel and is worn in the same area as a sleeve end. The bracelet can be thrown away when it is chewed up. There are also items of jewelry made with chewable parts and are specifically meant for people who need to chew and fidget. Point out the habit when you see him doing it. If someone else makes him aware of his behavior, he may stop himself when he is doing it later on. Seek medical advice. The chewing may be a symptom of a more serious problem such as an attention deficit disorder. Talking with a counselor or psychologist can help you determine if the chewing is simple anxiety that will go away on its own or is something that needs to be addressed as part of a larger problem such as attention deficit hyperactivity disorder.
