Our Full Review

Once you are ready for a more serious approach on how to stop thumb sucking, you will consider products like the Dr. Thumb thumb guard. A lot of thought and testing went into its design, and it is a thumb sucking device that was introduced in early 2000. The company behind this innovation took their work seriously and even conducted a clinical trial (discussed below), which focused on children under 4 years old. Very good results can be expected as long as your child is within a narrow age range of 3-5 years old, although there has been some success with both younger and older kids. And if you chose this product be sure to measure you thumbsucker ahead of time and order the right size. This thumb sucking device fits either the right or left hand.

The function of this product is unique. It still allows the child to put their thumb into their mouth, but because of its design it “breaks the vacuum” effect so they cannot get the comforting feeling of sucking. So air passes right through when they suck. The theory is that the pleasure will be lost and the child will no longer desire the thumbsucking action.

My 18-month-old daughter was a heavy thumbsucker and we really wanted her to stop because her teeth were shifting forward. We first tried Thumbusters, but she was able to take them off. Then we got this Dr. Thumb thumbguards and she was not able to it off. She cried the first day of having to wear it, but then got used to it. After about a week she completely kicked the habit!

Right off the bat, the Dr. Thumb is more effective than a thumb sucking glove because it is more difficult for them to get it off (but not impossible), and it is more effective than anti-nail biting polish like Mavala Stop because young children quickly get used to its taste. This product is also easy to attach, made of non-toxic silicone, and less expensive than its direct competitor the T-Guard. Cons include that it is somewhat uncomfortable to wear, and is difficult to clean as dirt/germs and slobber collect in the creases and can eventually find their way into your child’s mouth. And as will almost all products that help kids stop thumb sucking as well as stop sucking fingers, the child can still put their thumb in their mouth while wearing it – sure they may take less pleasure, but it does not prevent them from doing it.

The company claims your child can stop sucking thumb in two weeks, and separately they claim 92% success rate. While their data is based on “fuzzy” testing, in truth, with an involved parent and a motivated child this is possible. In fact, that is really the secret for success with breaking any unwanted habit. However, if the parent is not involved then the kid won’t be motivated and simply won’t wear it or will take it off when mom isn’t looking. While this thumb guard may be a great choice, read on and compare it to other solutions to make sure you have the right choice for you, and pay close attention to sizes, comfort and the “cool factor”, and how ready and willing your child is to stop thumb sucking.

The company Dr. Thumb also created this excellent short, one-minute video that is worth watching. The company is out of the United Kingdom, which makes finding the product in the US sometimes difficult, and returns may not be worth the effort depending on who you buy from. At the time of this writing, their price of about 25 British Pound Sterling converts to $37 USD.

The Dr. Thumb website has a lot of great information and an easy-to-read format, and they appear to be a good company. A have certainly done their research and have a wonderfully informative website.

A common question is about Dr. Thumb thumb guard vs T-Guard thumb guard, don’t worry, many people get this confused. First, while similar products they are sold by different companies. Dr. Thumb sells only one thumb sucking guard product, in two sizes. Contrastingly, T-Guard (the company) sells a stop finger sucking and a stop thumb sucking device, and either can be purchased in any of three sizes. Both products are specifically designed for both baby thumb sucking ages 1-3, and kids ages 3-7. None of these companies sell products for adult thumb sucking. There are several other important differences. Compare all the best devices to stop thumb sucking here.

  • Very effective for ages 2-5
  • Easy to use
  • Non-toxic silicone
  • 5+ year olds remove it
  • collects slobber/germs
  • child can’t use hand

Size matters. Although both manufacturers report that their thumb sucking guard is designed for baby thumb sucking all the way up to seven years old, they both work extremely well for kids between 3 and 5 for a couple of reasons. In both cases, thumb and wrist sizes of little kids below three years old, generally, are just too small for the product to stay on. Kids squirm, skin stretches, and with their slobber is a lubricant the thumb will find its way out of the guard and into the mouth. You could tighten the wrist strap, but in some cases moms have reported that over tightening causes abrasion. For mild mannered babies though, this may be a problem. On the other hand, kids over five years don’t like that the thumb guard gets in the way of their play time, and kids older than five are smart enough to remove the thumb guard. Moreover, comfort is a very important factor to kids when trying to get them to comply, especially those kids five years old and up. Although these guards can be effective at stopping thumb sucking, they are not comfortable, and they get in the way of basic activities such as using silverware or drinking a cup of milk.

The company Dr. Thumb held a clinical trial at Yonsei University in 2001, which included 25 children. Of the subjects, (7) were one-two years old, (10) were two-three years old, and (8) were older than three. At that time (it is assumed) there was only one small size, and it was designed for baby sucking thumb problems.

The company now has two sizes. Results were measured after four weeks. After four weeks, 24% of the children completely stopped thumb sucking, 68% showed less thumbsucking, and 8% did not show any improvement. And those who successfully broke the habit did so in an average of 2-3 weeks. As an aside, for comparison purposes it would be helpful to see a clinical trial on thumb sucking adults and people who want to know how to stop finger sucking.

As you can see, Dr. Thumb thumb guard takes their unwanted habit stopping business seriously. You can also visit their Facebook page and see photos of children who successfully stopped!

    I bought this Dr Thumb and used it combined with Mavala stop. Combination of both worked wonders on my 3 year old son. After three days he stopped sucking his thumb!
    I have to say that I do think this is a bit unsanitary because it collects wetness from his mouth and dirt sticks to it. I wanted to sterilize after 24 hours of having it on my child’s hand, but it got really dirty between the creases and it is hard to wash. It’s also hard to put to his hand, but we figured it out (it’s hard to keep a 3 yr old from moving for even 5 minutes!). BVesides that I am thoroughly pleased with the purpose of the product. It worked and we’re all happy that my son no longer sucks his thumb!

    After reading an article in the NY Times this Dr Thumb product for thumb sucking seemed like a great idea. I wish I had found this site first and seen the thumb sucking product reviews first. The Dr. Thumb did not work for us, it was just simply tooo easy to take off. My son if five, and he is way to smart for this. It might work well for 2-3, maybe four year olds. So now I’m going with with Editor’s choice for thumb sucking product.

  3. Richelle Clearwater says:

    Dr Thumb worked very well on my one and a half year old. It is small and fit good. True, it got a lot of spit though. If he were bigger and stronger I think he could have wiggled out of it but for me it worked. It took a long time. I put it on every night for three weeks but was inconsistent during the daytime. Would putting it on daily too have shortened the duration I wonder?

    1. Jane says:

      Thanks for your Question! Yes, definitely. The more the thumbsucking habit is not active the faster the child will learn not to do it, and replace that comfort with an alternative. Remember, it is best to give positive reinforcement when the child is not sucking their thumb, then negative feedback when they are. Praise is always more effective than punishment.

  4. Linux says:

    If your child predominantly sucks just one thumb, our research has shown that it is unlikely they will begin sucking the other thumb after putting on the guard.

    1. Jane says:

      What research? Based on a wide research of customer reviews from Amazon, I see that about 20% of children will switch thumbs, if an appliance is used to stop their dominant hand.

  5. Jake says:

    Works great! My 4 year old daughter has been using it for a few days. She wants to quit and is ready and just needed a little helper. I liked the price of this one and is just what we needed.

    I used this for my two and a half year old, it worked for one day until I realized that it was too tight and leaving a mark behind on his skin. When we loosened it to make it more comfortable the thumb guard was difficult to keep Dr Thumb on his hand, and he quickly learned how to remove the thumb component by pulling the plastic with his teeth and at the same time pulling his thumb under the guard. When we tightened it up just a bit to prevent this he started chewing through the plastic and started to tear the thumb guard. I also found that my son would suck on his thumb with the guard on causing saliva to be trapped between his thumb and the guard. I really liked the construction of the Dr Thumb product and wanted it to work… so I am very disappointed.
