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

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

  • 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”.



Works for Nose Wounds from Thumb Sucking!

My daughter had sucked her thumb since she was 4 weeks old. It wasn't a big issue until around 16 months when she fell down and cut her nose. Well, as many people know, thumb suckers often rub their nose (or another object) while sucking their thumb. She continued to rub this wound open for over a year. At 2 1/2, I'd had enough! As soon as we'd think it would heal, she'd break it open again. I knew the "old methods" would never work and I didn't want to continously nag her about it so I went online and found these. I thought if we could get her to stop sucking her thumb, this would keep her hands away from her face and allow this wound to heal. I bought these thumbguards and we called them her "special bracelets." She was super excited. I left them on nearly 24/7 and only took them off for bath time. She quit thumb sucking within a week or so and the wound went away within a week--a wound she had for OVER A YEAR! I continued to leave the guards on for another 5 weeks (I saw that the success rate was better for kids 3 yo and she was only 2 1/2 when we used these so we left them on extra long). Her sleeping was not affected at all. Initially, she did struggle to calm down if she got upset, but not too much longer and we tried to teach her other ways to self soothe. I highly recommend this product. I literally had to do nothing except make sure they were on at all times. She was actually disappointed once we took the "bracelets" off :)

I never write reviews, but in this case felt compelled to. Our 4 year old daughter had been sucking her fingers since birth, and nothing we tried to stop her would work. We were ready to try anything, but didn't really expect much since so many other methods had failed. She was excited about trying this method, but began chewing the fingerguard so much that it was damaged within the first week....I was even more skeptical at this point, but we pressed on. I had to trim off damaged portions a few times, but stuck with the program. Amazingly, after the one month timeframe she was ready to remove the guard, was VERY proud of herself and has not sucked her fingers since. Her dentist is very happy, and I am truly impressed.
