New and recommended! We are glad to present the newest version of our highly successful thumb sucking treatment kit: AeroThumb®! Based on the same principles as our TGuard Classic, AeroThumb’s improved design offers an ergonomic fit that will fit on your child’s hand like a glove, helping you to stop the thumb sucking habit in a comfortable and effective way. Ventilating holes ensure cool air flow, which allows the device to be worn without any worry of condensation build up. More adjustment resolution means you can get a tighter, more precise fit.

In short, our new design is more comfortable, more ergonomic, and is far more effective than our 20 year old classic design.

If you are looking for a guaranteed way to stop thumb sucking in 4 weeks or less, without causing pain or discomfort, then look no further. Most parents see results after only ONE week of using AeroThumb, making it one of the most recommended solutions to break the thumb sucking habit.

Kit Contents

Each treatment kit contains everything you need to stop the thumb sucking habit for one hand, within 30 days.

  • 1 Ambidextrous AeroThumb™ appliance (can be worn on either hand)
  • 30 bracelets: fun to wear, and multi-colored, so children can choose a new color every day!
  • 1 Instalock – makes the fitting process as easy as possible!
  • One set of instructions
  • Reward chart + stickers

Please note: Many children will switch from one thumb, to the other, after putting on the TGuard. For that reason, we recommend purchasing two treatment kits, one for each hand.

Sizing Chart

Sizing can be a tricky matter and it’s very important to get the right size in order to have a successful treatment. We recommend the table below for most children.

Weight Under 40 lbs Between 40 and 70 lbs More than 70 lbs
Recommended Size Small Medium Large

Typically, a child under 4 will choose small, a child ages 5-6 medium, and a child above 7 will choose large. However, the weight chart is the most accurate way to gauge sizing, and we recommend purchasing based off a child’s weight, rather than their age.

If your child is very close to the cut-off between sizes, then go with a smaller size if the child is taller, or a larger size if the child is shorter. The reason for that is because the only important parameter in sizing is the relation between the thumb width and the diameter of the tube. Taller children tend to have more narrow thumbs and fingers, so they should go down a size, while shorter children tend to have wider thumbs, meaning they should go up a size. The length of the thumb plays no role in sizing.

Please know that children under 3 are more likely to switch from thumb to finger sucking, or vice-versa, due to their habit not being fully matured. If you see that the child switches from thumb to finger sucking, please contact us.

  1. Highly recommend! My 10 year old son stopped in 11 days! Hallelujah 😁

  2. I had my hesitations with this product, but it did actually work. It took maybe a month or so? At some point my little lady started sucking her other thumb so we had to buy another one, but in seemingly no time at all we are free of thumb sucking!

    The stars and the colored bracelets really helped to get my daughter excited about actually wearing it and whatnot. Very pleased, would definitely recommend!

  3. Patience is key, but, it works!!! We’ve used this on both our kids. The first week is the hardest but consistency and patience are keys to success!

  4. We got the T-Guard on the advice of our orthodontist. Our daughter was willing to break her night-time habit, and she tracked her progress on the chart that came with the device. She never missed a night and, by the end of the recommended usage period, had no inclination to revert to her old thumb-sucking ways.

  5. This product is amazing

  6. This product is amazing! My son sucked his thumbs all day every day. After 44 days with the TGuards he hasn’t sucked his thumbs once. I was so overwhelmed by the thought of breaking this habit and am so thankful that a friend recommended these. They are easy to use and work!

  7. My granddaughter is 8, and the thumb guard broke the habit. She is happy that she no longer socks her thumb.

  8. In less than a month our daughter had completely stopped sucking her them. She only had to wear them at night to get out of the habit.

  9. we stuck with it for 2 months and it worked great!

  10. Great product, my 5 years old daughter just stopped sucking her thumb in 3 weeks. Thank you 👍
