Oral & Dental Health

Nursing Caries

A specific pattern of severe dental caries in infants and young children, typically affecting the upper anterior teeth, caused by prolonged exposure to sugary liquids from a bottle or frequent night-time breastfeeding.

Also known as: Baby Bottle Tooth Decay, Early Childhood Caries (Severe form)

Referral and warning signs

When to refer

Refer ALL cases of suspected nursing caries to dental personnel (HC4/RR) for assessment and management.

Red flags

  • Signs of dental abscess/facial swelling.
  • Child refusing to eat due to pain.

Signs and symptoms

  • Characteristic pattern of decay: Initially white spots, progressing to brown/black cavities, often starting on the labial (front) surfaces of upper incisors.
  • Decay rapidly encircles affected teeth.
  • Canines and molars affected later in order of eruption.
  • Lower incisors usually spared (protected by tongue/saliva).
  • Pain, difficulty eating (later stages).
  • Potential for abscess formation.

Risk factors

  • Frequent and prolonged bottle feeding with sugary liquids (milk, juice, formula, sweetened drinks), especially at naptime or bedtime.
  • Frequent, prolonged on-demand night-time breastfeeding after 15 months of age.
  • Poor oral hygiene in infant/toddler.
  • High maternal cariogenic bacteria levels (transmission).

Diagnosis

Clinical assessment

Based on characteristic pattern and distribution of caries in primary teeth of infant/young child, combined with history of feeding practices.

Investigations

  • Dental examination.

Diagnostic criteria

Clinical appearance of extensive caries on smooth surfaces of primary teeth, particularly upper incisors, in an infant or toddler.

Management

Non-pharmacological management

  • Feeding Practice Modification (Crucial): (LOC: HC2+)
  • - Discontinue night-time bottle feeding with anything other than water.
  • - Avoid frequent, prolonged on-demand night breastfeeding after ~15 months (advise scheduled feeds or water).
  • - Avoid using bottle as pacifier.
  • - Transition to cup by age 1.
  • Oral Hygiene: (LOC: HC2+)
  • - Gently brush child's teeth twice daily with age-appropriate (pea-sized) amount of fluoride toothpaste as soon as first tooth erupts. Avoid swallowing toothpaste.
  • - Wipe gums clean even before teeth erupt.
  • Dental Treatment (Referral): (LOC: HC4/RR)
  • - Restoration (fillings, crowns) of affected teeth to restore shape/function.
  • - Interproximal disking (smoothing between teeth) to create self-cleansing areas.
  • - Extraction of severely decayed, non-restorable teeth.
  • - Management often requires sedation or general anaesthesia.

Pharmacological treatment

  • Regular professional fluoride varnish application. (LOC: HC4+)

Monitoring

Regular dental follow-up to monitor existing restorations and detect new lesions.

Complications

  • Pain, infection, abscess formation.
  • Difficulty eating, poor nutrition.
  • Premature loss of primary teeth -> Malocclusion, space loss for permanent teeth.
  • Impact on speech development.
  • Poor aesthetics, psychosocial impact.
  • Increased risk of caries in permanent dentition.

Prevention

  • Educate caregivers on appropriate feeding practices (avoid sugary liquids in bottle, limit night feeds, transition to cup).
  • Initiate oral hygiene (gum wiping, brushing) from infancy.
  • Use appropriate amount of fluoride toothpaste.
  • Establish early dental visit (by age 1 or within 6 months of first tooth eruption).
  • Maternal oral health.

Patient education

  • Explanation of cause related to feeding habits.
  • CRITICAL need to modify feeding practices (especially night-time bottle/breastfeeding).
  • Importance of early and regular oral hygiene.
  • Need for dental treatment.
  • Preventive strategies for other children in family.

Uganda-specific notes

Nursing caries is prevalent due to feeding practices and limited awareness. Management is challenging due to need for specialist pediatric dental care. Prevention through caregiver education is paramount.
