Why is TGuard™ recommended to stop thumb sucking the most?

  • AeroThumb™ takes less than 4 weeks to completely break the thumb sucking habit.
  • 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.


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.


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 a comfortable and ergonomic fit that will fit on your child’s hand like a glove. 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 habit.

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.

Age / Weight Age: 0 to 4 (under 40 lbs) Age: 5 to 6 (between 40 and 65 lbs) Age: 7+ (more than 65 lbs)
Recommended Size Small Medium Large

While the table above will work for most children, if a child is in between sizes, or has a height / weight that is greater than the 80th percentile, or lower than the 20th percentile, the printable pdf file below may be helpful. It contains a tool which will assist in determining the exact right size for your child.

Click here to download the TGuard sizing PDF.

To use the tool, simply print out the PDF, cut out the banner, and wrap it around the thumb. The point at which the paper overlaps will indicate the right size.

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.

    Worked for two of my kids at 3 years of age. Within 1-2 months.

  2. Colleen Warning-Davis

    My 15 month old had her first dentist appointment, I was told that even though she only sucked her thumb for maybe an hour a day total, it was already moving her jaw. We bought 2 Tguards. She wore them 24/7 except for bath time which is when I cleaned them. She only wore them for about a week and half before she figured out how to get them off. Even though she was supposed to wear them for 30 days, on Thanksgiving we took them off late morning. It’s been a day and half and she hasn’t sucked her thumb. I am prepared to have to start over if she does. But right now I’m taking as a win. I highly recommend these guards and I highly recommend you start you child young.

  3. Lorraine Brown

    I used this product for both my daughters who sucked their thumbs from birth until 6-7 years old. I was amazed at how it worked, after trying all kinds of tricks, I was ready to give up. I highly recommend this product to parents. My older daughter stopped sucking her thumb completely after a few weeks, night and day. She was 7. My youngest stopped completely as well after the 30 days. She was 6. It’s been a year now and neither of them restarted. I couldn’t believe it. I have such faith in this product!

    My daughter has been a thumb sucker since I was pregnant with her. We have sonograms with her sucking her thumb almost every time. She is 8 years old now. The Tguard has been awesome! The plastic is very soft and has not caused any dry skin or redness at all. We only use it at night though. She has worn it for several months now and never sucks her thumb during the day. She will still put it in her mouth in the middle of the night if we forget to put it on her out of habit. 8 years of thumb sucking has been a hard habit to break. The tguard has been such a help. I do recommend getting two though because my daughter has switched thumbs and we ended up ordering a second one anyways. Hopefully we have corrected the habit to help her adult teeth growing in straight! Thank you tguard! I only wish we’d found this sooner!

    I have to say I wasn’t sure anything was going to stop my kids from sucking their thumbs. Their (pediatric) dentist even told me not to bother with it these types of appliances or nail polishes or anything, that they will stop when they’re ready. Well I am so glad that I gave the tguard aero thumb a chance. Yes it is a bit pricey, but it works and the company will work with you if the size is wrong. Let me save you the trouble, just buy 2. My daughter (5) has only ever sucked her left thumb so I tried to get away with just buying 1 for her. Well she had no problem switching thumbs. Regardless it has been less than the 30 days and both her and my son (3) have completely stopped sucking their thumbs during the day. I don’t even have to put the appliances on them anymore during the day. I do still continue to use them at night because I can’t see if they are sucking at night in their sleep due to habit. I plan on using them at night for a while until I know for sure they aren’t sucking their thumbs.
    Long story short if you’re thinking about trying the aero thumb, just do it it’s worth the money.
    The appliances also never bothered either one of my children.
    Thank you tguard!

  6. KA

    So thankful I found tguard for my twins. We went a few days after the 30days. My girls actually asked for it to be put back on each time we had to clean it. No more thumb sucking

  7. Christie Friestad

    It works! After trying every hack and method for years to break my daughters all day thumb sucking habit, TGuard was the winner. We put one on both her hands because she WAS an ambidextrous thumb sucker. What I loved was that it didn’t hinder her normal activities, like coloring, swimming, or eating. It can get wet without needing to be “changed”. I’m telling my friends to use this product. It’s worth the investment.

  8. Oyinkansola Olatunji

    This product worked for my 1 year old in just 20 days!!! When I say it’s fantastic. Believe me. First week he cried and broke out in hives as he was a prolific thumb suckered but boy did this work. Didn’t even finish the wristbands
    A I highly recommend

  9. Melissa Ogden

    Best option available!!! Worth every penny. We tried the arm brace that doesn’t allow them to bend their arm all the way and it didn’t work (because they can still suck their thumb), we’ve tried coating his thumb with something sour, and even scolding him but nothing stuck… Until we tried the TGuard. Our son was persistent enough that 3 weeks wasn’t enough so we ended up leaving it on for over a month (we periodically took it off to thoroughly clean it and give him a chance but he proved several times that he wasn’t ready for it to be taken off). We have extra straps because we would keep one on for several days before cutting it off and changing it. Highly recommend! Our son was pushing his teeth out already and he was still 2 when first got it so hopefully any damage he caused won’t affect his permanent teeth too much.

  10. Brooke Canchola

    The thumb guard works really well. The guard did cause a really bad burn/rash. We only got to use the guard for 11 days. It did stop her from sucking her thumb, but we had to stop using the product.

    • TGuard Support

      We have since reached out to this customer to address the reason for the rash, which happened to be because the size was too small. We have since sent the customer a replacement appliance in the medium size, which is fitting better.
