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. I was skeptical because my son had been sucking his thumb for years and we had tried everything to stop it. However, he used these guards for two weeks and has not sucked his thumb since! It was incredible and worth every penny!

  2. This product worked for my son within 7 days.He hasn’t sucked in over 6-months. Only regret is not buying it much earlier. I have to state that he didn’t get any injury or pain to his thumb during treatment. It was such a smooth process.

  3. My seven-year-old wore his medium sized aerothumb guard for almost 30 days straight which really helped him during that time. He just had the night time habit to break, but then the thumb guard broke. Customer service was slow to respond, but they did honor their warranty. In the lapsed time, we are dealing with not as much thumb sucking, but have to start over. It has certainly helped and hopefully will help our seven year old kick the habit completely.

  4. Oh finally. Something worked. Hallelujah.

  5. It worked perfectly! We wore it for about 6 weeks on both thumbs because my daughter sucked both. She was still able to hold pencils and crayons etc. We are so grateful for the Tgaurd

  6. My 1 1/2 yr old would constantly suck his thumb. To sleep, to soothe and no matter what we tried at home, it simply did not work. We didn’t want his teeth to shift or develop an open bite. We purchased the T guard as our last hope. We were hesitant because it was more expensive than the other options on Amazon. We decided he definitely needed to try it. About a month or less of wearing the thumb guard and taking it off when he slept. He finally stopped! He would get the urge and would put his thumb in front of his lips but wouldn’t suck it. That stopped too. This worked amazing! He was able to eat, play, grab things with it on no problem. I loved that! Easy to clean and breathable. I highly recommend T guard 10/10!!! Definitely worth the money, saving your baby’s teeth and saving you thousands on future dental work.

  7. Both of my kids were thumb suckers. This was the only thing that got them to stop. We recommend it to eveyone when they are trying to figure out how to get their kids to stop sucking their thumb.

  8. This was the last attempt before a semi permanent orthodontic device for an 11year old!!! I was skeptical of this pricey piece of plastic but it did the trick!

    She wanted to stop thumbsucking but couldn’t kick the night time habit, she put the tguard on each night herself, didn’t even bother to lock it. She filled out the chart on her own and each week I bought her a pack of gum to reward her success (and to chew when she was craving her thumb- car trips!).

    It’s been 4 months since she stopped using the tguard and until seeing this email, I had nearly forgotten about the decade long saga of trying to nix the thumb sucking.

  9. The quality is nice but my 4 year old can squeeze her thumb out of this and then suck it. The size is appropriate based on her weight. Maybe the original would work better for her but we won’t be using this unfortunately.

  10. I bought this for my nine year old after a friend recommended. My son was a nighttime thumb sucker and we had tried different methods to ween him off with no success. This device was easy and comfortable to use and worked like a charm. Used it for a couple weeks longer than the recommended 30 days and it’s now been over a month and with no thumb sucking.
