Soft plastic, breaks vacuum so sucking is not pleasurable, good company support.

Thumb can slip out, collects germs and kids may chew it, cannot wash hands, difficult to use.

Our Full Review

A child with the finger sucking habit may easily switch to sucking another fingers on the same hand, or the opposite hand, making stopping the finger sucking habit a bit more challenging than quitting thumb sucking.  While the TGuard Aerofinger covers the preferred fingers, you should be prepared to buy a second aerofinger if your child switches hands.  Your child may receive equal satisfaction by switching fingers they suck on, making the problem hard to address.

The AeroFinger is for the serious finger sucker because it can be made extremely difficult to remove, and can be effective when the included program is followed.  Sometimes just putting on the product for a few days is motivation enough for the child to stop fingersucking.

The device is secured around the wrist with disposable bracelets.  They come in different colors so the child may choose a different color each day.  The Tguard Aerofinger treatment kit comes with 30 bracelets, which may last just two weeks if you use two per day.  Expect to use 1-3 bracelets a day as the device may need to be removed to be cleaned or for certain daily activities such as hand washing, PE at school, etc.  Additional packs of 60 bracelets cost $25.

Be prepared to spend extra $25 (+shipping) for replacement bracelets! Each time your child needs to wash, you must cut the bracelet to remove Tguard. If your child washes their hands just three times per day, you’ll run out of the included bracelets in ten days (TGuard recommends a thirty day program).

The T Guard AeroFinger covers two fingers at once, and works by eliminating the vacuum effect from the finger sucking habit.  The TGuard Aero-Finger is an improvement on the TGuard Finger-Guard, and is designed with additional vented slots on the sides of the silicone rubber to allow airflow and reduce trapped moisture.  Both anti finger sucking devices work by eliminating the sucking pleasure.  While trapping of slobber and germs due to sucking is not completely eliminated with the Aerofinger, it is greatly improved.

The silicone device is designed to be worn on any two adjacent fingers (but not the thumb, that is what the AeroThumb is for).  The product comes in 3 sizes: small, medium and large. Measuring the child’s hand before ordering is very important for a correct fit.

  • Small: for children ~ 2-4 years old, who weigh < 40 pounds
  • Medium: for children ~ 5-6 years old, who weigh 40-55 pounds
  • Large: for children 7 and older, who weigh > 55 pounds
  • Order a smaller size if the child is thinner, or taller, than an average child of their age;  or order a larger size if the child is heavier, or shorter, than an average child of their age.
  • Tguard designed the product to work on any two adjacent fingers.  As can be imagined, the pinky is not the same size as the middle digit so getting the right size for effectiveness and comfort can be tricky.  If your child is able to wiggle fingers out of the device, use a second bracelet to strap the device around the palm of the hand – but while this can solve the problem it’s a lot of trouble to take on/off the device throughout the day.

The wearability is our harshest critique of the TGuard AeroFinger (and Fingerguard).  Getting the right size and fit is necessary for it to be effective but even with the right size, the discomfort is still a factor. Soft fabric finger gloves such as the Glovey Huggey will stretch and conform, but Tguard’s silicone is hard against the soft skin between the fingers.  For some children, chaffing can occur between the fingers due to constant contact and rubbing (if this happens, use band aids in the areas where the rubbing occurs).  Other kids chew on the tips of the soft silicone when they do not get the satisfaction from sucking.  In cases like these, some parents will use Tguard with other products such as a bitter nail polish.

The Tguard are secured around the wrist first with a small plastic piece that hold the device in place before applying the disposable bracelet.  Without this little “Instalock” piece, the device will not be able to be secured on the body.  It is important not to lose it (replacements are available on their website for a few dollars).  The included instructions and user guide cover all the things you should consider as you decide to help your child stop the habit using this product, so do take the time to read it.  The backside of the user guide server as a chart for your child to track the number of nights they have been wearing the product using the star stickers (also included).  It is a grey scale picture of the night sky with some trees.

The Tguard company, around since the 1990’s, has made improvements to their two products in the last few years.   The product is FDA listed medical grade silicone rubber, made in the USA, BPA and phthalate free.  They offer a 30 money back guarantee from the date of purchase and have phone and email customer support.

Problems with products that come in multiple sizes: You may decide that now is the time for your child to end digit sucking. You may decide soon after starting a program that it may be better to wait a few months for one reason or another, an illness, an issue at school or maybe interrupting your child’s habit may be harder than you originally thought.  You may invest in a solution to stop the habit today, but after a growth spurt the product you purchased no longer fits.  At the Tguard Aerofinger price point we suggest to be sure you are ready to stop the habit.


  • The TGuard AeroFinger is for the serious finger sucker who need a device secured that cannot be removed.
  • FDA approved rubber, breaks the vacuum and removed pleasure of sucking.
  • Collects germs and slobber, may not work if child switches fingers.
