How to Stop Biting your Nails

Sometimes nail biting can be compounded with other issues, and in order to ensure we can help you, the first step is to complete a very short questionnaire. The next step, is to order the self-impression kit (no shipping costs, worldwide).

The process is simple: take an impression of your teeth, and send the kit back to us.  We will manufacture custom-made devices that will make  you stop biting your nails for good. No one will be able to notice that you’re wearing the hidden devices, and your diction will not be altered.

Our clinic specializes in curing compulsive nail biting, with a unique device which makes it impossible to bite the nails and cuticles. The deterrent device is the best solution and the greatest hope for nail biters worldwide.
After only 2 months of using the deterrent device, the impulse to bite the nails and surrounding skin will disappear in 90% of the patients. You will be able to remove the device and never bite your nails again.

How to cure onychophagia - chronic nail biting?

Ironically, nail biters are typically perfectionists about their nails and surrounding skin, and although they try to limit this behavior, they only cause more damage. The tips of the fingers graze each other,  usually without noticing, until a rough edge is felt. This sensation triggers the hand to raise up to the mouth and address the imperfection. The tip of the tongue locates the precise location of the rough edge on the nail’s surface and then an order is sent to “fix” the rough area. The only issue with this is  that the teeth are tearing the nail and surrounding skin, and will leave the fingers more damaged and rougher to the touch. As a result, the tip of the adjacent finger again feels an imperfection, another order is sent from the brain to fix the problem… and the never-ending cycle continues.  

Stop biting nails with the help of a unique invention - the nail biting deterrent device

Using the Nbite© device is analogous to locking a person in a prison cell – in the beginning the urge to break free and leave the cell is strong. However, whenever they try to open the door they face the fact that the door is locked. As the time goes by, the urge to escape lessens until there is an acceptance of the situation – and the will to break free is stopped. A very similar thing happens while using the deterrent device – at the beginning the brain sends an order to bite the nails regularly as the urge is still strong. But when the hand reaches the mouth, the brain realizes the option to bite the nail and skin is ‘locked’.  At the initial stage, your brain will test its boundaries and will try to bite the nails and skin repeatedly, but continual use of the nail biting deterrent device over 2 months of treatment will eventually, eliminate the nail biting urge.  

How to stop biting your nails?

In order to stop nail biting, there are two things that you must do, it is extremely important to understand that both of them are crucial and without them both you won't be able to stop biting your nails:

  1.  Stop the trigger for nail biting

  2.  Stop the nail biting urge

How can you accomplish these two objectives?
In order to stop what triggers nail biting you have to make sure that the fingernails and their surrounding skin will be soft and smooth to touch at all times. People who suffer from nail biting are perfectionists regarding the feel of their nails and cuticles - every imperfection in one of the fingers is felt by the adjacent fingers, as a consequence the brain sends an order to smooth the rough nail and as a result the hand goes up to the mouth. when the finger enters the mouth, the tongue locates the exact location of the rough nail or skin , and the teeth execute the precise order originated in the brain. I'm sure that what you think now is: "that is exactly what happens to me!". We know nail biters so good since we cure nail biters on a daily basis. In order to stop nail biting we will make you a tailor-made deterrent device this special deterrent device will prevent you from causing any additional damage to your nails and cuticles, and by that a fast healing process will start. The main purpose of the Nbite© nail biting device is to stop the nail biting urge completely.

How long does it take fingernails to grow?

When no damage is done to the nail, the nails' growth rate is approximately 3.5mm per month, so that until the end of the 8 weeks nail biting treatment, each nail will grow about 7mm. Usually the nails' growth rate is even faster after long years of nail biting, especially among children. In order to stop the initial nail biting trigger we provide three special, 7 sided files that will help you maintain smooth nails and skin. The smooth nails and skin will help you to stop the nail biting trigger and will stop the constant movement of the hands to your mouth.

What is the nail biting deterrent device and how will it prevent you from biting your nails?

The Nbite© deterrent devices are tailor-made devices made from an FDA-approved material,  aimed at curing nail biters.

The devices are made from a completely transparent and an extremly thin material  (0.004 of an inch or 1/10th of a millimeter).

 This transparent coating will cover your front teeth and, therefore, your teeth will  no longer be sharp. It is like coating the two blades of a pair of scissors, once the blades are no longer sharp the scissors can’t cut. Thus, the teeth can no longer cause any damage to the fingernails and their surrounding skin and all damage is prevented.  Once the nail biting device starts protecting your fingernails and skin, you simply won’t be able to do anymore damage - simple and effective.
An 8-week nail biting treatment not only totally prevents nail biting, but also completely stops the nail biting urge.
After 8 weeks, the nail biting deterrent devices can be removed and they won’t be needed anymore – in most cases, you will never bite your nails and surrounding skin again.


In order to manufacture your specific deterrent devices, we will send you a special kit in order to get precise impressions of your upper and lower jaw structures. You will send the impressions back to us and we will produce two custom Nbite© devices for each jaw, that will fit your teeth perfectly and cure you. You can stop biting your nails it is just a matter of addressing the problem in the right way.

Will anyone notice the nail biting deterrent device?

No one will be able to see a difference in your diction or looks while you wear the nail biting devices. Our list of ex-nail biters include singers, radio broadcasters, teachers, psychologists and doctors – all of whom continued with their everyday work with no interference while using the Nbite© devices, without anyone knowing that they are wearing them.

In addition to email support, we offer scheduled consultations via Skype at no additional costs.

If one or more of your devices becomes impaired for any reason, another device will be sent - free of charge.

We will send you a special kit to take the impressions of your upper and lower jaw. The kit includes 6 dental trays for the upper and lower jaws and 6 portions of a dental putty, which is enough to take 3 impressions for each jaw. To ensure accuracy in designing your devices, we include 2 extra molds and extra dental putty for any mistakes you might make.

After you send the finished impressions of your teeth to us, we will produce a total of 4 tailor-made Nbite© devices for you. This package includes 2 spare devices, as it is important that you will have a backup device for each jaw.

The 4 devices will be sent to you along with 4 special nail files, each of which has 7 different sides that can gradually file and buff your nails and skin until they become smooth like silk.

In cases where the nails are severely damaged as a result of several years of nail biting, the treatment might take longer than 8 weeks, and in these cases additional files and Nbite© devices will be added at no extra cost.

During the 8-week nail biting treatment, we ask you to send weekly email updates and pictures of your nails so that we can provide feedback and monitor your progress. You can follow this link to view our before and after examples from past patients.

The Most Comprehensive Nail Biting Related FAQ 

Breaking the myths of nail biting

Contrary to common belief, nail biting is not a bad habit, but rather an impulse originated in the brain, therefore the use of will power or bitter substances is not effective for the purpose of rehabilitation from nail biting, as you probably noticed already by yourself. The impulse is stronger than us, therefore the stick and the carrot method or using will power alone, will work only temporarily, and the urge to bite the nails and surrounding skin will soon return.

Artificial nails are not a solution to nail biting

Nail biters also bite artificial nails and by that they preserve the urge to bite, and just hide temporarily beneath plastic nails. A psychological therapy is also inefficient since the motive to nail biting is not an emotional one, thinking that nail biters are stressed is a common mistake, since the vast majority of nail biters define themselves as ordinary people without any special tendency to tense or anxiety. After so many years with no cure, we invite you to carefully read the information in this website in order to get rid of nail biting once and for all.

Stress and boredom enhance the nail biting; however they are not the cause

You bite your nails and the surrounding skin because the urge in innate in you and not because you are stressed. Most nail biters start biting their nails and surrounding skin before the age of 6, think of how many stressful situations you confronted with every day at the age of 6, if indeed stress is the cause why not all stressed people bite their nails? Don’t you know other people who are stressful than you that don’t bite their nails?

The majority of nail biters that we have treated had no mental problems, no childhood trauma, and no anxiety or stress more than the common person, yet they have been biting their nails throughout their entire lifetime.

The reason you haven’t managed to stop nail biting is because you haven’t treated the root of the problem – the basic urge. The good news are, that since the patent for treating nail biting was first introduced in 2006, the urge can be totally suppressed. The success rates are 90% among the patients who completed the 8 week treatment.

What are the causes for nail biting?

Why bitter substances are not effective in curing nail biting

There are 4 main reasons to why nail biters bite their nails:

  1. A genetic origin – the nail biter should check whether one of his parents, siblings, grandfathers or grandmothers also bite their nails. The more relatives bite their nails the more the chances are that there is a genetic connection.

  2. An imitation of a meaningful person during childhood – little children tend to imitate a dominant character, it could be the nanny, the babysitter, a sibling or a close friend. Once a child starts biting his nails the biting is fixated, if the nail biting will continue during adolescence it is probable that the nail biting will stay for life.

  3. In some cases nail biting follows a traumatic event, sometimes as a means of getting attention from other people, and sometimes to find a release.

  4. The minority of nail biters start biting their nails apparently with no reason even as adults.

    No matter the reason, the success rates of our nail biting treatment are 90%.


The bitter chemical used in most of the products aimed at treating nail biting is Denatonium benzoate or Bitrex its commercial name (the bitterest compound known). It is a chemical compound, which is toxic when consumed in high levels. Every nail biter who had tried these bitter products admits that the bitter taste penetrates the food, and make the life of the nail biter and his family miserable. These products do not prevent nail biters from biting their nails since the bitter taste is not strong enough in order to stop the impulse and soon enough the nail biter gets used to the bitter taste. Besides the fact that Bitrex is a chemical compound it doesn’t solve the nail biting problem and sometimes even worsens it, as the frustration that comes after the returning trials that didn’t succeed leads to a desperation and a loss of hope that the nail biting can be solved.

Why artificial nails aren't a good treatment?

Most nail biters will also bite their artificial nails, this way the impulse to bite the nails is maintained. Though the nails grow a bit under the plastic cover, when the artificial nails peel off the nail biting urge will continue. Plastic nails might lead to nail fungus, because moisture might enter between them and the natural nail. Usually, the natural nails need to be filed down in order to build the artificial nails, which harms the natural nails even more. In addition to these health problems artificial nails, are expensive since every two weeks they need to be fixed or replaced. Spending money just to hide behind plastic – is an unhealthy, short-term solution for a long-term problem.

Does nail biting cause irreversible damage to the teeth and nails?

Prolonged nail biting might harm the base of the nail and cause a deformation in the nail structure. The nail grows on the nail bed and, thus, hurting the nail bed causes a separation of the nail from its connective tissue – and in all cases, the nail will not fully re-attach. Therefore, the sooner the nail biting problem is addressed and taken care of, the less irreversible damage will be caused.
According to the Academy of General Dentistry, children or adults who bite their nails could crack, chip or wear down their front teeth from the stress caused by nail biting. And those who wear braces put their teeth at an even greater risk for root resorption (a shortening of the roots) or tooth loss, since braces already increase the pressure on the teeth. A study in the journal ‘General Dentistry’ also reported that nail biters might be at a greater risk for bruxism — unintentional grinding or clenching – and this can cause facial pain, headaches, tooth sensitivity, recessed gums, and tooth loss. Other dental health risks for nail biters can include sore, torn, or damaged gum tissue caused by jagged, sharp fingernail edges and the spread of bacteria from other body parts to the mouth. This transmission can carry on to the nail bed and/or bloodstream.

Does nail biting have an influence on life expectancy?

There is research that suggests a direct connection between nail biting and low life expectancy, similar to the anecdote of heavy smoking. The reason is probably related to the fact that nail biters keep introducing toxic chemicals and germs into their body throughout their life. Nail biting may also lead to heart disease.

Who can’t undergo the nail biting treatment and why?

We only treat patients aged 13 years or older.
The main reason is the fact that the teeth of young children are still growing and the Nbite© nail biting devices interfere with their growth. In time, the devices will not match the growing teeth of the child. We can’t treat patients with braces who are currently undergoing orthodontic treatment, however, if the patient only has a single, thin metal wire at the back side of their teeth, our nail biting treatment is possible

Will I develop a different compulsive disorder after I stop the urge to bite my nails?

The answer is… definitely not.

Nail biting is not a habit but rather an impulse, the minute this impulse is switched off, no other impulse will take its place. Your nails contain no addictive substances (like nicotine), and therefore the rehabilitation process will not lead to greater anxiety, edginess, aggression, or hunger. Many people are convinced that the action of nail biting keeps them calm and if they will stop biting their nails their tension will find their way to develop into other bad habits. One can find a release from everyday tensions in many ways that do not involve self-mutilation and sometimes irreversible damage to the nails. Even the most tense nail biters can stop biting their nails and enjoy life!

I also suffer from anxiety and stress, can I still be treated just for nail biting?

The answer is definitely – yes! Even if the nail biter also suffers from anxiety or stress he can be totally rehabilitated from nail biting. There is no direct connection between mental health problems (i.e. stress or anxiety), and nail biting. In times of stress, a nail biter is likely to bite their nails more, however, this stress only enhances, not triggers, the condition. Some people consider seeing a psychologist in order to stop nail biting, however, psychological therapy is inefficient in curing nail biting. Among our patients there have been many psychologists and psychologists’ children. If a patient is a stressed person, s/he will stay that way until the end of the treatment… but they will no longer bite their nails. Our treatment does not involve psychological therapy. It does not address the emotional side but rather it deals with the prime reason for nail biting – the urge. 99% of our patients have declared that they do not suffer from any stress or mental disease, and they described themselves as ordinary people who were not any more anxious, stressed or restless than the average person.

What is the nail biting deterrent device?

The Nbite© deterrent device is a tailor-made from FDA-approved material, and solely aimed to cure nail biting. In order to produce the Nbite© deterrent devices, we will send you a special kit in order to get precise impressions of your lower and upper jaws. You will send the impressions back to us, and we will produce 2 precise Nbite© devices for each jaw that will fit your teeth perfectly and free you from nail biting.

Is there a connection between nail biting and social anxiety?

Nail biters often suffer from low self-esteem, and they are embarrassed by the looks of their hands and usually try to hide the nails during social interactions. The nail biting treatment will enable you not only to get your old nails back but also to free you from embarrassment and help you gain more self-confidence.

Is there an addictive substance that makes me bite my nails?

Nails do not contain any addictive substances, the nails are simply made of Keratin, which is the same material that the hair on our body is composed of. The Nail biting is not an addiction, but rather an uncontrolled impulse which originates in the brain.
