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. So awesome! My dentist recommended it for my 3 year old because her thumb sucking habit was too constant and it worked immediately! She just stopped putting her thumb in her mouth. So shocked! Definitely a life saver, thank you so much for this invention!

  2. We had a wonderful experience with the Tguard. We talked it up for a few weeks and had family and friends send cards of encouragement. By the time we started the guard, my 5 year old daughter was cautiously optimistic. She loved the colored bracelets and found the guard comfortable enough. She was able to play and color and participate in all of her normal activities. In just 4 days we were able to remove the guard during the day! Now she only uses it at night and I feel confident we’ll be over the habit soon!

  3. It worked!! We had to use the thumb guard for a little longer then recommended but it broke the habit!! Thank you

  4. It worked well! We had it on for 28 days though, just to be sure it stuck. After the first two weeks, she seemed to still want to thumb suck.
    It was hard because no one in our area seems to do this or even know of it, felt a bit cruel. But we took it off on her first birthday and we didn’t regret the purchase!
    I’m a family Dr myself and I know the kinds of complications that can be caused by thumb sucking, dermatitis and teeth problems. To replace the soothing thumb sucking gives, we gave her extra extra special love!!
    Great product!

  5. This product worked 100% My child was about 2 years 9 months when we decided to use the TGuard. She had thumb sucking habit for more than 6 months and so we decided the habit had to be stopped. Our pediatrician recommended this product and we thought we’ll give it a try, we were not sure if it will work. The quality of the product is pretty good. We followed the instructions of continuing for 30 days daily and to give the child an incentive (like a candy or something) to wear the TGuard. The first 3 days, our child was not happy about wearing it and tried to remove it but she was unable to remove it. Later on, she got used to it. So, my recommendation is to give it a try, Yes, it is expensive but totally worth it, if it works. Make sure to do for 30 days completely. We needed to be patient but in the end it worked out.

  6. After eight years of trying absolutely everything with nothing working, this broke the thumb sucking habit within the 30 days. I left it on at night for a further 15 days because it’s more subconscious, but not sure whether that was actually needed. When it was a risk purchase i.e. not knowing whether it would work it felt like a lot of money, but knowing now that it works it seems cheap and I’d spend the money again and again. Would highly recommend.

  7. We’ve been trying for a year to break our daughter’s thumb sucking habitat with some success and a lot of rebounding. It has been two months since we stopped using the TGuard for the recommended 30 days and she still has not once sucked her thumb! Worth every penny. We’re looking to get the finger guard for our son since he sucks his two middle fingers.

  8. I am absolutely amazed by this product! I wish I had skipped all the other attempts at breaking my son’s thumb sucking habit and just used this. I would highly recommend this to anyone that is trying to break a thumb sucking habit.

  9. Finally did the trick! The lock band is crucial because during the night, thumb sucking is subconscious and inevitable. The sticker chart is a nice challenge and adds a visual guide to our sons success. He no longer sucks his thumb and his dental hygiene has improved due to less germs being in his mouth!! Thank you so much!

  10. It worked great! My almost 3-year-old seemed to loose the desire to suck her thumb very quickly! We couldn’t be happier. It was hard the first few days when she was trying to fall asleep for nap or bedtime but it wasn’t too long until she found a new way to cope (snuggling a new stuffed animal). The star chart worked great as well.
