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

To find out more about TGuard Technology, and how our products work to stop the thumb sucking habit, check out our TGuard Technology page.

Key Facts

Why is ThumbGuard recommended the most?

  • ThumbGuard takes less than 4 weeks to completely break the habit.
  • ThumbGuard is made out of 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.

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”.

I read the reviews and thought, "yeah, but I really don't think this will work for us." Our daughter whom just turned 7 was literally sucking her thumb in the womb. We tried a lot of different methods and nothing was working. We were one step away from orthodontic treatment and I decided to do one last Google search for ideas. This website came up and we decided to give one last ditch effort. We have been using the thumb guards for a little less than a month and have seen a HUGE improvement. She can now watch TV with no thumb sucking. She really is only wearing them at night at this point. My only concern is that I feel that I need to make the bracelet quite tight in order to prevent her from slipping her thumb out. We LOVE LOVE LOVE this product.

My girl is 21months old
She has been a thumb sucker since she was 6 months
I will go directly to the point
I used the smallest size
First three nights (and midday naps) were a hell of crying/screaming cos she couldn't access the wife had to hold her all night long. .
After 3-4days ..she stopped that crazy screaming and started sleeping calmly; but she started another bad habbit of being closely attached, physically, to her mother during sleep not allowing her even to move.
She hasn't tried to remove it to much.
By 3 weeks she forgot about the thumb..
I am thankful to tgurad..

I got the ThumbGuard about a month ago and my daughter who is turning 5 has been wearing it since.I put the thumbguard on the finger that she had been sucking since she was a baby and within two days she was sucking the finger on the other hand(I never thought that would happen)so I put the second one that I thought was just extra.For about a month she is wearing it on both hands and the fingers are not in her mouth but when I took it off to wash it and forgot to put it back one night the finger was in her mouth right away. I'm not giving up yet but I'm starting to have doubts that it will work.Hope I'M WRONG!!

Response: Susan,
Thank you for your review. The treatment only works if you are consistent in it\'s application - she must go 30 days without sucking her thumbs. Please contact our support team for more help.
