Our Full Review

The ThumbGuard, now known as the TGuard Classic, is made of a flexible, clear FDA-approved materials and is designed to stop thumb sucking in children.  How does the ThumbGuard work? The thumb sucking guard is fastened to the wrist using colorful, disposable Tguard bracelets.  By covering the thumb and leaving an air gap, the child cannot create a suction when they put their thumb in their mouth, so they lose the feeling of pleasure and comfort, and hopefully then stop the thumbsucking habit.  The concept is simple, by removing the benefit the child is inclined to quit on their own.  Still, your child’s motivation is essential to success.

The child can continue to put their thumb or fingers in the mouth, encouraging the oral habit or a transmutation of one oral habit into another.  The oral fixation is the crux of the problem and is not necessarily eliminated with this approach.  The child may decide to continue sucking or chewing on the device.  This is the same type of material teething toys are made of.  The device will need to be cleaned throughout the day as many times as you encourage your child to wash their hands.  If the device is not completely dry, irritation may occur on the finger.  The bracelets are one time use only and refills are pricey.   If your child does not quit the habit quickly you’ll find yourself spending another $25!

The thumb sucking guard, Tguard Classic, comes in three sizes: small, medium and large.  Small is for ages 3-4, medium for 5-6, and large for 7-10.  Be sure to order the right size, because as children grow at all different rates the age range does not necessarily correlate to the size.  The manufacturer does not specify an upper age limit.  Older children are usually unwilling to wear it as it is obvious what it is used for, and because of embarrassment.  Slipping the thumb out of the device is the most commonly reported reason for failure.

The product is one of the original thumb sucking products on the market, is sold internationally, and has been effective for many children so it deserves a good rating.  While TGuard is simple in principal, the disposable bracelets can be difficult to put on and the child cannot do it on their own.   As long as it stays on and the thumb remains covered, your thumbsucker won’t continue enjoying the sensation and indeed has a good chance at successfully quitting the habit.  Without motivation, the child usually finds a way to wiggle out or an excuse to fail.  Many people have also reported that children are able to slide their thumb out when it gets wet from slobber.  If you have it sized correctly this should be less of a problem.  Please remember, as you will read repeatedly throughout this review site, positive encouragement and parent involvement, incentives and even bribery are key to getting your child motivated to quit.

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.  Thumbsucking is often an embarrassment to children of about five years old and up (size medium or large), and wearing the Tguard over the hand is not desirable because it limits usefulness of the hand.  Its functionality is equally as important as its comfort, and if your child is old enough to care, then so is its “cool factor.”  This demonstrates the difference between a motivated and unmotivated child – a motivated child really just needs the reminder, and will not cut the bracelets because they understand the device helps them.

The manufacturer of the T-Guard The company offers excellent support to their existing customers.  Once you are a customer you can even call their support phone number and speak with a real human who will coach you along.

The company also is inventor of the Fingerguard for finger sucking.  The company offers multiple sizes for both the Finger guard and Thumbguard.  Their multi-product line is a good sign that the company and products have marketplace acceptance.  If purchased directly from the manufacturer you are offered a 30-day money back guarantee.  If you think you might use the 30-day money back guarantee, save all of the packaging and everything that came in the box, because in order to get your refund you must return everything within the time window.  You’ll also be responsible for your own shipping charges plus 15% restocking fee.  This return policy applies to all of the products including those for fingers and thumbs.

For reference, below is a photo of the fingerguard next to the thumb guard.


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 (recently the Tguard aerothumb surpassed it in price).  Seriously stubborn suckers may switch to the opposing hand.  When the hand switching does happen, it is response during the first few days.  For these reasons, if cost is a concern for your, buy one and test it out first.  If your child stops thumbsucking on their dominant hand and switches, then buy a second thumb guard.

The original design may interfere with developmental learning if worn for a longer period of time.  Learning to write or writing in general and developing the pincher grip are all part of early childhood development.  The cone over the dominant thumb may interfere with developing those skills if worn for an extended time.

For the seriously stubborn thumbsucker be sure to do your research.  Useful information in one place to save you time, and for complete stop thumb sucking guard product reviews see our homepage, and read the general tips at the bottom of the homepage. This information in one place to save you time.

We encourage you to do complete research before buying any product because your child has only limited patience when it comes to breaking the thumb sucking habit. 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.

    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.

    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.

    It’s been 3 days since we took it off (after wearing for 3.5 weeks). It was seccure but he did develop 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.

    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. D says:

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

  6. Jules H says:

    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.

  7. tried tguard too expensive says:

    My son could get his thumb out and when he left his thumb in, he sucked on it until it started to fall apart. I don’t like that we have to repurchase ties for it either. These are really expensive then you have to buy the straps. I’m going to try a differnet product.
