Medical Attention for Delayed Tooth Eruption in Babies

Medical attention should be sought if a baby has no tooth eruption by 18 months of age, as primary teeth typically begin to erupt around 6 months and should be present by 12-13 months. 1

Normal Tooth Eruption Timeline

  • Primary teeth typically begin to erupt at around 6 months of age 1
  • Most children have all 20 primary teeth by age 3 years 1
  • The American Academy of Pediatric Dentistry and American Academy of Pediatrics recommend establishing a "Dental Home" within 6 months of first tooth eruption but no later than 12 months of age 1

When to Seek Medical Attention

Age-based Guidelines:

  • By 12 months: If no teeth have erupted, this warrants discussion at the 12-month well-child visit
  • By 18 months: Medical evaluation is definitely needed if no teeth have erupted
  • Any age: Prompt evaluation is needed if there are other concerning symptoms such as:
    • Facial swelling
    • Signs of oral abnormalities
    • Developmental concerns
    • Pain or discomfort

Risk Factors Requiring Earlier Evaluation:

  • Family history of delayed dentition
  • Developmental delays or disabilities
  • Craniofacial abnormalities
  • Genetic syndromes
  • History of endocrine disorders

Potential Causes of Delayed Tooth Eruption

Delayed tooth eruption can be caused by various local and systemic factors 2:

  • Local factors:

    • Dental crowding
    • Physical obstruction (e.g., cysts, tumors)
    • Trauma to developing teeth
    • Ameloblastic fibro-odontoma and other odontogenic tumors 3
  • Systemic factors:

    • Nutritional deficiencies
    • Endocrine disorders
    • Genetic syndromes
    • Systemic diseases

Evaluation Process

When a child presents with delayed tooth eruption, the following should be performed:

  1. Thorough clinical examination:

    • Assessment of overall development
    • Examination of oral cavity for signs of swelling, color changes, or abnormalities 1
  2. Radiographic evaluation when indicated to:

    • Confirm presence of tooth buds
    • Identify potential obstructions
    • Detect abnormalities in tooth development 2
  3. Referral to appropriate specialists:

    • Pediatric dentist for primary dental evaluation
    • Other specialists based on suspected underlying conditions

Common Pitfalls to Avoid

  • Dismissing parental concerns without proper evaluation, which can lead to delayed diagnosis of underlying conditions 1
  • Attributing serious symptoms to teething - fever over 102°F, significant distress, or refusal to eat/drink should not be attributed to normal teething 4
  • Failing to establish a dental home by 12 months can result in inadequate oral health monitoring 1
  • Overlooking signs of potential child abuse in children under 5 years with unexplained oral/dental trauma 1

Management Approach

Management depends on the underlying cause:

  • Normal variant of delayed eruption: Monitoring with regular dental visits
  • Local obstruction: May require surgical intervention
  • Systemic condition: Treatment of underlying disorder
  • Symptomatic management for teething discomfort when appropriate:
    • Non-pharmacological approaches (cold teething rings, gentle gum massage)
    • Age-appropriate doses of acetaminophen or ibuprofen for persistent pain 1
    • Avoid benzocaine products in children under 2 years due to risk of methemoglobinemia 1

Early identification and management of delayed tooth eruption are essential for preventing potential complications related to oral development, feeding, and speech.
