White Spots on Nails (Leukonychia)

Understanding the causes, symptoms, and management of small white marks on fingernails or toenails.

What are White Spots on Nails?

Do you notice small white marks or streaks on your nails? Learn what causes white spots and when to seek care.
White spots on nails, medically known as leukonychia, are small, usually harmless discolorations that appear on the nail plate. They can result from minor trauma, nutritional deficiencies, or underlying health conditions. While most white spots are temporary, persistent changes may indicate an underlying issue requiring evaluation.

Common Symptoms

  • Small white marks or streaks on one or more nails
  • Nails may appear slightly brittle near the spots
  • Usually painless and not associated with other symptoms
  • Spots grow out with the nail over time
  • Occasionally accompanied by slight nail ridging

When to see a dermatologist

  • White spots persist or spread over time
  • Nail becomes brittle, thickened, or painful
  • Multiple nails affected without clear cause
  • Associated with other symptoms such as fatigue or hair loss
  • Suspected nutritional deficiency or systemic illness

Early detection is important for managing the condition and preventing further complications. Schedule a consultation today.

Causes and Risk Factors

  • Minor trauma to the nail matrix (bumping or pressure)
  • Zinc, calcium, or protein deficiency
  • Allergic reactions to nail products
  • Fungal infections or bacterial nail infections
  • Certain medications or systemic health conditions

Diagnosis and Tests

  • Physical examination of the nails
  • Review of medical history and diet
  • Blood tests to check for vitamin or mineral deficiencies
  • Nail culture if infection is suspected
  • Assessment of recent nail trauma or cosmetic procedures

Treatment Options

  • Most white spots resolve as nails grow out
  • Address underlying nutritional deficiencies
  • Avoid trauma to nails and practice gentle nail care
