Dear Dish-it: Breaking a Bad Habit

Jul 05, 2013

Dear Dish-it,

I have sucked my thumb ever since I was little. Now I'm going into 6th grade and I still suck my thumb. Whenever I'm not sucking it I'm eating and I'm starting to get worried because my teeth are starting to push out. Please help!

Thumb Sucker

Dear Thumb Sucker,

Breaking a bad habit is hard to do, especially when you've been doing it all your life. Unfortunately, thumb sucking after age 5 can cause many problems, both with your dental health and your skin.

Dental Problems

Once you have your permanent teeth, it's important to take good care of them. As you mentioned, thumb sucking can cause your teeth push out. This will eventually give you an overbite or alignment problems that only an orthodontist can fix. By breaking this habit now, you could potentially save your parents thousands of dollars. Along with dental problems, you could also begin to experience speech problems, such as a lisp.

Skin Problems

Prolonged thumb sucking will eventually cause skin irritation on your thumbs. This could come in the form of calluses, dry or chapped skin, or even fingernail infections that could slow or stop the growth of your nail. Chapped skin on your thumb will likely entice you to suck more, but resist the urge! It will only make it worse.


Cold turkey is obviously the best way to break any habit, but I'm sure by now you've tried that. Don't replace this bad habit with another one, like eating or nail-biting. This will only lead to further problems down the line. Instead, try applying bitter-tasting nail polish to your thumb nails. This technique is commonly used to stop nail-biting, but it could also work for you as it will make your thumbs taste bad. In place of this polish, you could also spray your thumbs with perfume or hair spray. If this doesn't work for you, try wearing mittens or gloves. Obviously, this isn't practical for school, but at home, and especially in bed at night, this could prevent any unconscious thumb sucking.

Okay so basically I used to go to this school and I met some of the people who I wish to be life long friends with. Problem: All of them go to a different school Problem: I go to a dumb boarding school and only get to spend 1 day and a half with them when i come back on fridays before I leave to go to school on Sundays. I really hate this school too. My sister graduated high school from here and my other sister is in her last year here. After this year I'm going to be all alone at this school. I'll have to be going here for the next seven years since its a middle and high school and I'm only in middle school. Plus my sisters are the best students there. Every time I tell people I'm the sister of Stephanie and Siri,they automatically have high expectations of me. But mainly,I just want to know how to keep in touch with my best friends. We can't even have phones at school so I can't talk to them during the week. [s:sm3/1jw0]
