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. T guard worked wonders for us!!!! My son was VERY stubborn in kicking the habit so we also order these excema mitts and put the thumb guard over those as he started to suck his other fingers with only the t guard on. I highly recommend using the mitts (found on Amazon) for your little one if you’ve got a serious thumb sucker like we did.
    We wore them for two weeks straight, then for 6 weeks only at night/naps. We ordered extra wrist locks off Amazon too. It was worth it! He no longer sucks his thumb anymore.

  2. The strap that goes around the finger was rip off

  3. The thumb sucking stopped completely and never came back. My daughter had been sucking her thumb for 6 years, since she was a newborn. She loved the sticker chart and was eager to cooperate, she even named the Tguard “her best friend!” I couldn’t believe that it went so smoothly. So happy and relieved that it worked and the thumb sucking is gone for good.

  4. Worked like a charm! He wore it for 30 days, and he hasn’t sucked his thumb since!

  5. Really pleased with the product and customer service. We started about a month before my daughter turned 3 and she wore it for about 3 months. She chewed through the first one and we got a free replacement. She has had it off for about 2 weeks now and has not sucked her thumb once. She does a little hand to mouth motion (biting nail a little etc) but it’s minimal and redirectable and most importantly is NOT sucking. Very happy with the product!! It’s such a relief to have helped her break this habit. I should add that we only got one night of resistance and the rest was smooth sailing! We talked with her alot about it before starting, gave lots of positive reinforcement and prizes at first but eventually it was just normal for her to wear it and prizes weren’t really needed…we did give her a big prize for being all done though.

  6. Yes it worked better and faster than we expected. My son stopped sucking is thumb within a week of using it.

  7. The T-Guard was our last ditch effort in helping our daughter break the habit; I only wish we started with it and a whole lot sooner! She responded well after the recommended prep-time. We took away her nap; and waited till she said she was ready. The star-chart was a great incentive as well. After 45 days – she broke the habit. About 1 week later she fell ill and relapsed and started sucking her thumb again. Once she was feeling better, we put the T Guard back on. After a week- she was ready to take it off and has not sucked her thumb since. Her over bite has improved. Her teeth stuck out and already that has improved. She’s so proud of herself and we’d recommend this to everyone!

  8. Didn’t work well for us. No matter what we did, she took it off. If we tightened it, it left indentions and sores from rubbing. Too loose, she got it off.

    • Hi Shelby,
      It is likely the size purchased is too big. We have reached out to you to troubleshoot this issue. We are confident we can get you back on track!
      Kind regards,
      MED et al Inc.
