Nail biting is a nervous habit afflicting both adults, and children, which can rapidly become uncontrollable. Many children suck their thumbs, another bad habit that can deform the plate of the mouth and cause teeth to protrude.
Mavala Stop helps cure nail biting and thumb sucking by “warning” you not to put your fingers into your mouth. Its distinct bitter taste acts as a strong deterrent. MAVALA STOP has the appearance of clear enamel and does not stain fingers…. More >>

Mavala Stop-Nail Biting and Thumb Sucking Prevention, 10ml

5 Comments until now.
Before you put this on your child’s fingers you must taste this for yourself. If you cannot bring yourself to taste this then you shouldn’t put this on your child’s fingers. I put this on my child’s nails before I tasted this and once I tasted this I removed it off of my two year old daughters fingers. Both my wife and I would rather use a less horrible solution, such as Thum than subject anyone to this taste. My daughter quit eating my wife’s freshly baked sugar cookies the moment her fingers touched her mouth. She became very distraught to the taste of the Mavala on her fingers and we had to remove it.
Both my wife and I feel the use of this product is a form of child abuse.

My 5 year old won’t stop sucking on her index finger..we’ve tried a bunch of different products to stop thumb sucking and fingernail biting. All with little effectiveness.
I ordered this and another product similar to it and I swear she LIKES the taste of it. I’ve asked her if it bothers her or if is ‘icky’ and she’s told me no.
I’d say that’s a failure.
I wish I could say this helped at all, i’d like to find something nice to say about it (okay, it came nicely packaged) but thats about it.
I’d turn somewhere else to find a truely effective product to stop these habits.

I never received this item. I sent an email to the seller asking about it, and I never even received a reply. So obviously I am very unhappy with this order and would not suggest anyone else order it.

Our four-year-old son has sucked his thumb since day one. We are very concerned about this and have tried various methods to get him to stop.
After reading the many glowing reviews of this product on this and other websites, we decided to try it.
The first thing we noticed about the product we received was that it looked and smelled like acetone or nail polish remover. Alarmed, we contacted our dentist and pediatrician, both of whom advised us that the smell comes from solvents in the product which evaporate after application and should not pose a risk. With some trepidation, we decided to try the product anyway. The next things we noticed were that the product seemed to wear off rather quickly with our son and that he was willing to put up with the residual taste at prime thumb-sucking time (such as when he was tired).
Concerned about the frequency of application required, we then contacted the FDA Center for Drug Evaluation and Research to see if they had any information about the product. The FDA informed us it has not evaluated the product for safety or efficacy and advised us to submit a MedWatch Report for possible follow-up investigation. The official who responded to our inquiry seemed concerned about the solvents and alcohol that form the main ingredients of this product.
Note that the FDA official did not indicate that the product was necessarily dangerous. However, the official did seem to think that further investigation was warranted. For the record, our son does not seem to have suffered any ill effects after 4 days of use.
My son was recently promoted to the “big kids” class at his pre-school, and we’re very anxious about the physical and social effects of his thumb-sucking. We’re as eager as anyone to find a magic bullet to fix this problem, but we have concluded that using alcohol and solvents of unknown efficacy and safety is too high a risk. Note too that because the product is made in Switzerland, holding its makers accountable for any adverse effects that might occur would be difficult. Before using this product, you may want to ask yourself whether you want your kids to be guinea pigs for the untested products of a foreign chemical company.

Its unreal!!! Our eighteen month old has been sucking her thumb with gusto since she was born!! We have been wanting to do something about it so I searched using the Dealio toolbar for something to stop the sucking and came up with Mavala. Its unbelievable!! After ONLY one application she STOPPED COMPLETELY. Her thumb does not even go near her mouth anymore. So we gave it a shot with our four year old who was bitting her nails. You HAVE to see it to believe it. For the first time in years we cut her nails!! Yes, you guessed right. One application did it. This is for real!! Excellent, excellent, excellent!!!
