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. unfortunately it didn’t Work for us. It’s uncomfortable to wear and my son refuses to wear it.

  2. I highly recommend this product to stop thumb sucking. We followed the directions and are very pleased by the results. I would encourage any parent to give this device a try.

  3. This really worked for my 4 yr old. It’s a great product and I would definitely recommend it to others

  4. We used this exactly as the directions indicated for a month and while there was some improvement, it did not break the habit. At first it brought awareness to the habit and my 3 year old wasn’t sucking anymore. Then, he started chewing on it. Then, he just started sucking the other thumb, something he’s never done before. It’s also unreasonable that 30 straps would last 30 days. It doesn’t account for getting dirty or accidentally snapping on too tight or too loose and needing to use more than one strap per day. As we were getting low on the straps, but it hadn’t been 30 days yet, I didn’t have enough time to order through TGuard to get another set before we ran out so I ordered something similar from Amazon so it would arrive sooner. That worked for a bit but once those ran out, and he was sucking the other thumb, I gave up. I wasn’t about to buy ANOTHER guard for the other hand, plus more straps. At this point, a few months later, we’re in the same place we were before starting use of this guard.

  5. I wanted this to work so bad!! I even had to buy two, bc my daughter just started ducking her other thumb. Then with two she somehow managed to David Copperfield her thumb out, and I’m not sure how she did it, but she did and now she’s regressed a bit.

  6. Worked in a span of about a week.

  7. It really did get him to stop sucking his left thumb. Now, a month later, he has regressed and is sucking his right thumb

  8. This did not work. We followed the 21 days of continuous use and all it resulted in were blisters in between my toddlers thumb and pointer finger.

  9. It really works!

  10. Before finishing the treatment on his right hand, he began sucking the finger of his left hand. We feared it wouldn’t be working. At the end of the 30-day treatment, he sucked the finger of his left hand for a few days, but then miraculously stopped. Now he doesn’t suck either finger anymore. For us it has worked!
