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

    We had tried everything we could think of to get my 7 year old daughter to quit sucking her thumb when I saw Tguard online. After 30 days with the Tguard, she was finally done! She said she does not even think about sucking her thumb anymore! This product is amazing!

    I can never thank you enough for this amazing product. I bought it for one of my daughter after I wait 4 years for her to stop on her own. I tried everything nothing has worked. when she went to the dentist, the dentist told me to do something her tooth is getting deform. I finally decided to buy it after I read the review. one week only , it only took her one week to stop sucking on her thumb. thank you so much for this amazing invention.

    Wow! Ce fut un succès. Ça n’a pas été facile tous les jours, mais ma fille était très fière de pouvoir choisir ses bracelets de couleur. Elle se trouvait belle quand elle les portait. Elle avait 4 ans et demi et elle n’a pas recommencé à sucer son pouce depuis. Ça fait un an.

    We started off by using the classic Thumbguard but it was difficult to get the right fit for my son (balance of not too tight and not too loose). My son still sucked/chewed on the thumbguard which made it wet and he soon got a blister.

    We worked with the great folks at Tguard who offered us the AeroThumb. This is a major upgrade and I highly recommend it. The air flow is significantly improved and he can wash his hands and get it wet but it quickly dries. Also, the plastic seems much softer which means no more blisters!

    We’re still working on breaking the habit but the Aerothumb is definitely helping!

    This product has the potential to be wonderful. My five year old managed to get her thumb out wth the original design until I made it super tight. It then rubbed and caused damage to her skin so we purchased the areoguard. It’s ventilation is better however my daughter continues to pull out her thumb each night. We’re persisting but I must say I feel frustrated. If I tighten the devise it will damage her skin.

    My 4 year old son has sucked his thumb since he was 3 months old. I waited till he was ready to stop sucking his thumb and asked for help,- I was delighted to be able to order him help by purchasing tguard! We purchased the wrong size and tguard made the exchange process very easy! My son was eager to stop but would still try to suck his thumb out of habit but the tguard prevented suction and stopped the habit. And his preschool teachers loved that he could easily wash his hands! Thank you!

    Hey, mommas and daddy’s of thumb suckers. I was sharing with another mom (and thought I would share with others too) how wonderful this product is when you are ready. It is the BEST! As a former thumb sucker myself whose mother tried charts, rewards, taking my blanket away, changing the environment-all to no avail – I highly recommend this way of dealing with thumb sucking. My daughter used this at age 6 and my son at age 5. It’s still emotional for them the first couple of days-weeks but it is well worth it if you stick with it. My strategy was to let them suck their thumb until they started to loose teeth. That is the time where they NEED to stop so their adult teeth can come in straight. Both my son and daughter have beautifully straight teeth. I, on the other hand, had to have braces to correct my overbite that accommodated my thumb much too long. Again, can’t say enough good about this amazing product!!

    Good idea in concept, but if your kid is hell bent on doing it they still will. Just bought these for my 6 year old. At first, he was slipping out of it. After we tightened it up, he started chewing on them and bit through the plastic enough to be able to suck on his thumb again.

    I bought the ThumbGuard for my six year old daughter. I have to say I was worried that this would not work after I had tried many other things. After 44 days my daughter stopped sucking her thumb and she herself told me how happy she was that she had stopped sucking her thumb!! My daughter was able to do everyday tasks with the ThumbGuard on with no trouble. I love this product and I wish I would have found this a lot earlier. Thank you for making a product that worked!!

    We got a t-guard after getting off the phone with our pediatric dentist with a case of dizziness surrounding the cost of an orthodontic apparatus to stop our 4-year-old’s thumb sucking. She recommended the t-guard and even said it was less “traumatic” than a mouth cage. The first few days went great… I think because our 4-year-old had been well versed on WHY he has to stop (“can get teeth like a bunny”) and the included sticker-chart with his written reward (Lego dimensions for his Wii!). We took it off only for cleaning/bathing and though we had one spell of him sucking his thumb about 3-weeks in, we held strong. A little over a month in, we were able to only have it on at night when he is most likely to subconsciously suck his thumb at bedtime. Now? Not at all and we have ZERO relapse! I think it’s all about explaining the process, the age of the child and pure diligence in keeping up with it. He DID chew the apparatus for a day or two and it DID get a little discolored from the silicone material but nothing that changed it’s effectiveness and nothing that caused discomfort. I am SO grateful for this product as nothing else worked – not bandaids, other rewards, spicy nail polish, etc. I figured it wouldn’t work for me but took the plunge and I’m so glad we did!!

    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%.

    My son has been sucking his thumb since 6 moths old and now he is 2 years old. I had tried many things for him to lose the habit but nothing worked. He used the Tguard during full 30 days and he has not sucked his fingers since then. I’m from Brazil and we are very happy, thank you!

    I bought this for my 3 year old. She started to suck her thumb from the day she was born. I tried lot of things to get rid of this habit. At last I found this TGuard, read all the reviews and I thought why shouldn’t I give it a try? Then I bought 2 of them. In one week I could see a lot of difference. She stopped sucking during day time. Then she almost took another 2 weeks to stop in the night. After that I stopped using the Product. I am very happy I found this product and I would recommend this 100%.
