Dr Phil Kieran: How can I stop my son from biting his nails?

Nail biting in children is common, with approximately 20-30% developing the habit. Most of the time, the nail-biting is mild, and the child will grow out of it before 12.
Nailbiting, or onychophagia, can lead to sore fingertips, which are more prone to infection if the nail is bitten very short. It can also lead to dental issues such as chipped enamel, gum injuries or gingival infection due to minor trauma. At one time, there was a theory that nail biting increased the risk of acute appendicitis but this has been called into question.
If your child bites their nails, try to figure out why. It could be because they are imitating an older sibling or parent. It could also be a sign of anxiety or boredom.
Some children like to fidget and bite their nails to have something to do with their hands when sitting still. Another common reason is not liking the sensation of their nails dragging on surfaces or clothes.
For a child who likes to keep their hands busy, a fidget toy could be of benefit. For some kids who have gotten into the habit after imitating someone, a reward chart system may help them to break the habit.
Over-the-counter pharmacy remedies include a nail lacquer, which has an unpleasant taste. It can work well, but addressing the underlying reasons for biting is essential before trying to discourage it.
Another strategy is encouraging them to let one nail grow while allowing them to bite the other nine. As they adjust to this nail being long and having it cut, you can move to two pins, increasing until all nails are no longer being bitten.
Try to make it as easy as possible for them to break the habit. Keep the nails short and file any rough edges down to make them less tempting.
If it is the sensation of chewing they enjoy while watching TV, you could consider a rubber bite toy such as a sensory chew necklace or something similar. Sugar-free gum could be considered, although it could lead to arguments if it gets stuck to the cushions and furniture.
There is no one fix for nail-biting, but it is mostly harmless, and the child will grow out of the habit.
