Prolonged nail biting can lead to bacterial infection, damage to the nails and cuticles and dental problems.

  • If nail biting isn't due to stress, you can apply nail polish or try to engage them in paper crafts where their hands will be constantly working.
  • If your child is older, explain them that why they shouldn't bite their nails and what complications it may lead to.
