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.

Please note: Most children switch from one thumb to the other, when you apply the TGuard. For that reason, we recommend purchasing two treatment kits, one for each hand. Treatment for each hand includes:

  • 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!
  • Reward chart + stickers
  • One set of instructions

    Although there are numerous reasons to cease a thumb or finger sucking habit, the consequences of malocclusion, the expense of Phase I orthodontic treatment and fracture or avulsion due to protrusion of the maxillary incisors, are foremost. Metal appliances that may loosen or break and the challenges of alginate impressions with a gag reflex or poor cooperation are avoided with aerofinger and aerothumb. As removable appliance therapy (D8210), dental insurance may cover the cost. School-age children are at a developmental stage when competence is especially important. Emotional immaturity or inability to attain the necessary discipline to stop sucking may create stress, which in turn drives the habit. With compliance, aerofinger and aerothmb are effective devices to stop a finger or thumb sucking habit in as little as three days. Continued wearing of the device for the recommended 30 days is advised to assure complete habit cessation. Caregivers too are relieved with the elimination of frustration, constant reminding or admonishing. The device is usually worn at bedtime, but does not interfere with any activity, so can also be worn during the day. The newly designed aerothumb and aerofinger offer an improved design with ventilation, contours and flexible shape. Children are involved as they select from 30 colorful lockbands and enjoy the sticker book and stickers. Easy, safe and inexpensive intervention that decreases traumatic dental injuries and need for phase I orthodontic treatment, along with everyone’s satisfaction with success, earn a “thumbs up” from my practice for aerothumb and aerofinger!

    We ordered the Tguard for our 3 year old, and by day 2 she had converted to sucking on the other thumb. The look on her face when the 2nd Tguard arrived in the mail was priceless. As her mom put it on her, she cried and said I need something in my mouth mom, and started unbuttoning her mom’s shirt. This really worried us. I took her to the library and we found a few children books on thumb sucking, which she really enjoyed having read to her. Within the first week as she played with her dolls, we could hear her saying to them that she was going to go check the mail so she can help them stop sucking on their thumbs. It was the funniest thing I have ever heard. The guards are now off, and it is as if the habit had never occurred. I will recommend this product to any and everyone. It is money well spent. We had a small mailing encounter with the 2nd order, and the professionalism of Tguard’s customer service really presented itself and David straightened the matter out immediately. Thank you David.

    I don’t normally leave reviews, but I had to this time. The TGuard Aero Thumb has been amazing. It works! It was recommended to us by our dentist, who had serious concerns about our 3 1/2 year old daughters’ dental development because of her near-constant thumb sucking. We started with the TGuard about 23 days ago, full time for the first week, then part time (at times when she was more likely to suck: naps, bed, screen time, etc.). We have had it completely off for about a week now. Well, she has not sucked her thumb, or even put it in her mouth, since the first time the TGuard was put on. It well and truly made the habit disappear. It is easy to use, our daughter liked choosing her own coloured band, and best of all: it just worked. We are thrilled and have already recommended it to others.

    Goodbye Thumb Sucking…that’s what we are saying at our home! Our two-year-old no longer sucks her thumb…thanks to the Aerothumb. Many people told us, “she is too young, she won’t be able to stop.” But, we knew she could do it…so we made a plan, set a goal, and stuck to it…and success! We are so thankful for a thumb guard device that is easy to use and not cumbersome for her to wear. She was so aware of her thumb sucking, she didn’t have to wear the device all day. She only had to wear at naptime and bedtime. After 35 days…she is thumb sucking free! Thank you tguard for an amazing product. We are beyond grateful for the improvements in her speech already…words enunciated more clearly! Thank you too for the amazing customer service. We needed more bracelets and your staff were amazingly helpful and kind in processing our additional order. Thank you tguard for the the BEST thumb guard ever!!

    I just wanted to let you know how great this product is. At first we weren’t sure because we had a child who sucked his thumb all the time. After a week of having this on we could tell he was making huge progress and within 3-4 weeks he was completely broke of the habit. He has Not been wearing this for about a month or month and a half and has been thumb sucking free!! I can not tell you how appreciative I am of this product. It truly made this process much easier than we had anticipated. Thank you very much!!!

    I am very satisfied with this product, it really fulfilled and exceeded expectations. I bought this product earlier this year for our daughter of almost 5 years old, who had been sucking her finger since she was 2 years old ( I think). I never really did much to cut that habit, but since I was realizing that she was getting her teeth deformed and also because in September she will go to kindergarten, I started looking for information and also to ask the dentist if they knew any product for avoid that habit, but they did not help me much. so looking on the internet, I found this product and saw the video of promotion, as I found other products too, but this gave me more confidence, although its cost was a little higher than the others; but I think it was because of the video that has this page where they explain the whole process made me decide. During the treatment, in two occasions I forgot to put the aero thumb back to my daughter, and she tried to suck her finger again, and my husband felt a bit disappointed. I told him not to be disappointed, because we had to meet the total deadline to see results, and so it was …… at the end of the treatment (I extended it for 1 week, because my husband told me, in his distrust), the result was incredible, and never again has she gone back to sucking her finger again, the habit really was broken, and I am very grateful to you for having created this product. I really recommend it 100%.
