Kit Type: (see note below!)


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 ThumbGuard, making it one of the most recommended solutions to break the habit.

We now offer two different kit types – you can now choose a treatment kit for either one hand or for two. Please note: Most children switch from one thumb to the other, when you apply the TGuard. For that reason, we recommend purchasing the treatment kit for both hands. Treatment for each hand includes:

  • 1 Ambidextrous ThumbGuard appliance
  • 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

  • ThumbGuard is made out of FDA-listed, medical grade plastic, and is manufactured in the USA. The product is 100% BPA and phthalate free.

Sizing Chart

SIZING CHARTAge: 3 to 4Age: 5 to 6Age: 7+
Recommended Appliance SizeSmallMediumLarge

Please note that for children younger than 3, the small size can still be used. HOWEVER, the success rate cannot be claimed to be 95%, because very young children are more likely to switch from thumb to finger sucking, or vice-versa, due to their habit not being fully matured.

If your child is between sizes, please see our “sizing guidelines FAQ”.



6 year habit broken!

My daughter is six years old and sucked her thumb from infancy. She wore the thumb guard for over 45 days before we took it off to see if she had broken the habit. I noticed her sucking her thumb in her sleep two days later. I was disappointed but determined to help her totally break the habit so we put it back on for another month. She was trying to crack an egg a week ago and she was struggling because of the limited use of her thumb. So I removed it and haven't put it back on! It's been 8 days and today we celebrated with surprises and watching Mary Poppins live in theatre. We've checked on her at night and she has not been sucking! She said she doesn't even think about her thumb anymore. I have noticed over the last few months that she needs alot more hugs and is initiating cuddles -something new! I think a big part of the success was her willingness and cooperation. But obviously, a big thank you to Tguard for the product. Much more painless than dental appliances or endless teasing!

My daughter rejected her pacifier at about 3 months of age, and replaced it with sucking the first 2 fingers of her right hand. With each passing month the frequency of finger sucking seemed to increase and it wasn't clearly related to a specific stressor that I could identify. It just appeared to be developing into a frequent habit that I was concerned was beginning to interfere with her language development (talking less due to fingers always in mouth instead) and was also getting in the way of her getting involved in more hands-on activities/play than she would otherwise if her fingers weren't occupied in her mouth. A couple other considerations that made me take action to try to stop her finger sucking, was the possibility of it affecting her tooth alignment as well as the fact that she attends day care and would conceivably be exposing herself to even more viruses/germs by sucking on her fingers after touching everything! I also decided that I wanted to help her break the finger sucking habit before it became too engrained as a coping mechanism that would be much harder to change later on. I purchased the fingerguard for her between 22-23mths and followed the directions about not allowing her ANY opportunity to suck her fingers during the treatment period. I created a very positive feeling about the whole experience by calling it her 'special bracelet" and she actually asked for it to be put back after I had removed it for cleaning. There were no tears or wanting it off and no negative feelings at all about it. (I put it on her for the first time when we had a very busy/fun day planned with lots of activity that would keep her distracted so she wouldn't focus on this new device on her hand!) It worked like a charm! Within 3 weeks of use, it proved extremely effective in breaking her of the finger sucking habit completely! (The only things I did differently was to give her fingers/hand a break at night, I would remove the finger guard and put her to bed in an extra-long sleeve shirt with the arms sewn shut at the end instead so her fingers could move around naturally and I also made my own soft fabric bands/bracelets with buttons that could be easily removed and reattached for hand washing throughout the day, rather than the hospital style plastic bands that have to be cut off and can't be re-used after. These seemed more comfortable for her compared to the bands/bracelets that come with the finger guard as they have a tendency to dig into the skin a bit at the wrist area at times) The only negative feedback I have about the finger guard is that it did start to break apart on one side, where the finger tubes meet the hand piece, after only about 2weeks of use. Sure glad it was SO effective for us that we didn't need it very much longer because it would've continued to break apart and I would've had to purchase another one! Just for the record, I wouldn't have hesitated to buy another, if necessary, because the finger guard WORKS amazing and is well worth the small investment in my opinion!
