The ThumbGuard is made of a flexible, clear FDA-approved materials and is designed to stop thumb sucking in children. The thumb sucking guard, also known as the T-Guard, is fastened to the wrist using colorful disposable straps. Use scissors to remove. How does the thumbguard work? By covering the thumb and leaving an air gap, the child cannot create a suction, so they lose the feeling of comfort and eventually stop the thumbsucking habit. The concept is smart, you let the child continue to put their thumb in their mouth, and by removing the benefit they are inclined to quit on their own. Still, your child’s motivation is essential to success. If they are unmotivated, or you are unwilling to support them during the process of breaking a strong habit, their chances for success are greatly diminished.

Tguard product

The thumb sucking guard Tguard comes in three sizes: small, medium and large. Small is for ages 3-4, medium for 5-6, and large for 7-10. This product is not for adult thumb sucking. The manufacturer does not specify an upper age limit, but due to its maximum size it won’t fit larger children. Moreover, due to the way it looks and possible embarrassment when worn, older children and adults are usually unwilling to wear it. If you want to use the thumbguard for babies be sure to order the smallest one. For very small children, babies, or infants, be aware that because their thumbs are so small, that they can slip their wet thumb out of the device – this does not happen with all small children, but it is a commonly reported reason for failure.

The product has been effective for many children so it deserves a good rating. But there are some drawbacks too. First the positives. TGuard is very easy to put on – simply slip it over the thumb, insert the disposable strap and snap it on. It is easy to remove also – simply cut the strap with scissors. Another benefit is that it is clear so you can see when slobber or dirt builds up and it is time to clean. When sized correctly, the Tguard also stays on well using the disposable snap-on colorful straps. And, as long as it stays on your thumbsucker won’t continue enjoying the sensation and indeed has a good chance at successfully quitting the habit. Please remember, as you will read repeated throughout this review site, positive encouragement and parent involvement, incentives and even bribery are key to getting your child motivated to quit. If your child is motivated chances for success, with any product and even with breaking any habit, is greatly increased.

There are some drawbacks to the thumb sucking guard. The ThumbGuard looks “uncool” and isn’t very comfortable when worn. Does that really matter? Actually yes, because you want to get your child motivated and excited to quit sucking thumb. Its functionality is equally as important as its comfort, and if your child is old enough to care then so is its “cool factor.” Many people have also reported that small children are able to slide their thumb out when it gets wet from slobber, and older children are able to easily cut the paper strap. This demonstrates the difference between a motivated and unmotivated child – a motivated child really just needs the reminder, and will not cut the strap because they are grateful to have a device to help them.

Most of the time you will find the thumbguard offered in pairs of two for over $70! This is the most expensive device to stop the thumb sucking habit. Most of the time though, a child has developed a habit of sucking only one thumb so two Tguards are unnecessary. Seriously stubborn suckers may switch to the opposing hand, particularly at nighttime when sleeping. When the hand switching does happen, it is response during the first few days. For these reasons, we recommend that if you have decided this is the best product for your child, buy one and test it out. If your child stops thumbsucking on their dominant hand and switches, then buy a second thumb guard – they company does offer a discount when buying two at once.

For the seriously stubborn thumbsucker, be sure to do your research, and definitely avoid the bad-tasting nail polish like Mavala Stop. For complete stop thumb sucking guard product reviews see our homepage. We collected this information in one place to save you time.

The alternative is spending many hundreds of dollars on the “appliance” and eventually thousands of dollars on braces, or corrective surgery.


With an involved parent and motivated child, the thumbguard can save you thousands of dollars and a lot of time. As with anything online, just be aware of the pros and cons before buying to maximize your chances of success the first time.logo thumbs up

  1. The T-guard works great as reinforcement when your child can be convinced, or bribed to keep it on and WANTS to quit. Because of the stretchy rubber, there is no way to get it tight enough that they can’t pull the strap closures through each other and get them loose enough to get guard off if they really want to. The t guard took my kid less about fiver minutes to understand how to work this. However, with the right incentive (i.e. bribe) they will keep it on, and as long as they keep the thumb guard on it works. The Thumbguard can help them not to accidentally suck during the night and also work to remind them throughout the day – but again, getting them to wear this thing during the day can be a struggle. My child nibbles on hers, though, and the rubber can be bitten and nibbled away to reveal the thumb after a few weeks. If you are forcing this on your child – don’t waste your money. If they WANT to quit and agree they need help then this can work for you.

  2. Despite great reviews, this didn’t work for us. We gave it a good solid 3 months +. Our 4 yr old daughter began sucking her OTHER thumb. Didn’t want to purchase a second and have BOTH hands confined. So we decided to wait a little longer to reintroduce the idea, no I’m on this site looking for other ideas….hopefully she will be more at a point of WANTING to stop. I think you really need for your child to be on board and to truly want the help to stop the habit. Everyone is different, maybe the thumb guard will work for you.

  3. It’s been 3 days since we took it off (after wearing for 3.5 weeks). It was seccure but he did developt the habit of gnawing on the thing and it began to rip. I’d say the plastic needs to be harder and we put some foul-tasting substance on his favorite gnawing spots to counter the problem. In my opinion, still too expensive but can’t argue with the results when supplemented with mavala stop

  4. I tried the T Guard, and right away my son was able to pull it off. The straps are supposed to make it so the child cannot take it off, but it was so uncomfortable for him that he wouldn’t stop fussing with it. ANd kids are very creative and if they are uncomfortable it just won’t work. ANyway, the T Guard did not work for us.

  5. It worked for us in a week. My son could remove everything else, but this product actually worked. Far better than Dr. Thumb.

  6. Tried this, and besides making a mess with slobber my four year old kept removing it. Spent $45! Now I see T-Guard has another option that is supposed to be more effective but costs $60! For rubber and plastic this is way overpriced. I like the recommendation for Nipit, will try that now.
