Eruption of the first teeth

Deciduous teeth, also known as milk teeth, baby teeth, primary teeth or first tooth eruption are the first teeth that appear during human ontogeny.
This first teething usually occurs during the first two years of the infant’s life and often is an uncomfortable process and painful for the infant in many cases.

The following symptoms may appear, although not all of them must be present:


  • The infant puts their fingers and fists into their mouth, trying to bite to exert pressure on the gums.
  • Unsoothable crying.
  • Increased drooling, caused by increased salivation induced by teething.
  • Unusual irritability due to gum pain.
  • Difficulty falling asleep.
  • Decreased appetite due to the increased pain caused by sucking.

  • Low-grade fever due to inflammation.

The main consequences of teething in babies may be:


  • Sleep pattern disturbances.
  • Daytime tiredness.
  • Poor feeding with minor weight loss, in some cases.
  • Maceration with possible superinfection in mucous membranes and lips.
  • Alteration of skin around the mouth, cheeks, etc.
  • Irritability.
  • Impact on others: parents, siblings, etc.
