  • The TGuard AeroThumb product is made out of soft and flexible, FDA-listed, medical grade plastic, and is manufactured in the USA. The product is 100% BPA and phthalate free.
  • It has a success rate greater than 95%.
  • We offer a 30 day, money-back guarantee.


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. This really works. If you are dedicated and committed to it, you will see the results! So happy that my dentist recommended this for my 3 year old!!

  2. I saw a difference within 2 weeks from when I would take it off to wash it after week 3 I took it off completely but after 2 weeks of him not wearing it he started sucking his thumb again so this time I will do 4/5 weeks and then give another update…so I’m confident …but I can say that 12 years ago I got one for my daughter and it worked permanently after her wearing it 3/4 weeks straight and she never sucked her finger again … people ask me all the time what is that they never seen or heard of it and I tell them about it and the site …Thanks Tguard

  3. We thought we would never break the habit and even considered expensive dental implants. TGuard worked like magic. I only wish we had heard about it sooner.

  4. We purchased the thumb guard when my son was two and a half; he was sucking his thumb day and night. The 30 day period of full time use worked for us but this behaviour is a soothing mechanism which also needs attention. My son is now 5, and we still use the thumb guards at night.

  5. It didn’t work. We purchased two but whenever we would take them off for her skin to relax, she would go back right to the habit

  6. my daughter is 11 and we had tried everything. At this point she decided she really wanted to stop and she agreed to try Thumb Guard and it worked great! She is Thumb free now. Of course, the child also needs to want to stop, unless they are very small, but it was comfortable and not like a fabric guard that gets wet and annoying. In our area people have not heard about it, so her friends/teachers had no idea what it was which also made it easier and less embarrasing.

  7. It probably works if it’s not a strong habit but my daughter switched from the thumb to the fingers and even if we still put it at night with coton gloves as we have been recommended for a few months now , she stills is sucking her index .

    • Hi Chantal,
      Switching might happen occasionally for children under the age of 3. We do have techniques which can help address this issue.
      Please reach out to us for help!
      Kind regards,
      MED et al, Inc.

  8. I love the idea and had high hopes. I even bought a second one hoping that it’ll work only to have spent over $100 on a useless piece of plastic. My two year old figured how to take it off and tightening it did no good. It also left an unsightly bruise on his hand.

    • Hi Kenny,
      We are sorry to hear that the treatment hasn’t been working out so far. Please reach out to us for support.
      Kind regards,
      MED et al, Inc.

  9. It worked. My kid sucked his thumb at night. As soon as this went on, he stopped. The physical presence of the device alone was enough to get him to stop.

    After about 40 days, we stopped putting it on for bed and he stopped thumbsucking for good.

    It works.

  10. Unfortunately we purchased two and have used past 90 days and unfortunately my son is able to slip his thumb out and has not stopped sucking his thumb. Unfortunate this product didn’t work despite proper placement.
