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. Ventilated 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. The weight chart is the most accurate way to gauge sizing and we recommend going off of that.

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. I have a set of 5-year-old twins, both of whom are thumb suckers. We started the T-Guard with 1 at around 4.5 y/o, who had a callous on her thumb just below the second joint from biting while thumb sucking. She was determined to break this habit (which I think made a huge difference).
    We only took the T-Guard off only at bath time, and 45 days later, the habit was broken! 6 months later, my daughter still has no desire to suck her thumb and is SOO proud of herself! At our most recent visit to the dentist, the Dentist commented that there are noticeable differences in her overbite measurements, and the overall shape of her mouth and palate. The enunciation of her words is noticeably clearer as well.

  2. I don’t typically leave reviews, but this product WORKED!! My 6 year old struggled with thumb sucking despite multiple attempts at breaking the habit. We bought two thumb guards (one for each hand), gave him LOTS of encouragement, had some family members send him cards in the mail rooting for him, and had a sticker chart for the nights he made it wearing them all night. First few nights were a little hard for him to fall asleep, but with lots of positive words & comforting he did great. We started noticing after about 2 weeks he stopped putting his thumb in his mouth for car rides, a big step! After the 30 days was up he was broken of the habit completely. So thankful to have found this product!

  3. The product we received has a horrible mothball-chemical-old, old smell. Warm soapy wash per instructions does not help. Airing it out does not help. Could not find other reviews with similar issue on this website. Wanted to love it and try it, as a family member recommended it. I have not used this product at all–it smells so bad I wonder what is off-gassing from it. Not putting that near my child. If I can just use a bad smell to keep my child from sucking her thumb, I’ll just DIY it. I only saw one reviewer on Amazon who had the same problem, purchased around the same time as me. Maybe a recent change in plastic formulation/sourcing?? Returning now, sadly.

  4. I couldn’t believe this worked. Thank you so much.

  5. Its worked. It took almost 2 month but we got the results.

  6. Stayed consistent with it everyday and night for 30 days and it worked!!

  7. We used the TGuard for our 3-year-old daughter whose thumb-sucking habit was getting worse with time. It was a friend who told us about it. I ordered the TGuard plus extra bracelets just in case, as the shipping costs to Canada are quite high, but we did not need them. After 30 days of use, my daughter did not got back to sucking her thumb when we removed the TGuard. The first week was the hardest, as she would previously suck her thumb to comfort herself, but after that, everything went well. She was very proud to stick her stars on the provided sheet. On the very first day she wore it, her childcare educator commented on how much she had talked that day. It was money well invested for us.

  8. We started using the thumb guard at 18 months because she was developing blisters from sucking so much! Stuck to the recommended timeline, but she stopped trying to suck pretty early on (maybe after a couple weeks). She was only slightly bothered by the guard on the first day. Her older sister helped decorate the band with stickers and that immediately incentivized her to keep it on. We didn’t really need the chart, but maybe we’ll use it for potty training next! The guard got yellow pretty quickly, but that seems pretty inevitable for clear items like this. It is pricey, but because she was physically harming herself by thumb-sucking, we thought it was well worth the try!

  9. Worked amazingly my 3.5 year old. The thumbsucking was permanently broken!

  10. Worked wonderfully – in less than a month. Thank you!
