Perinatal and Infant Oral Health Care

Board takeaway

Perinatal care and evidence

• This source defines the perinatal period as before birth through 28 days after birth; infancy extends to the first birthday.
• Encourage parental oral care: maternal oral health and caries experience influence offspring risk. Care may prevent/delay caregiver-to-infant transmission of mutans streptococci (MS); dental avoidance and access barriers impede care.
• The update reviewed systematic reviews and randomized trials; insufficient/inconclusive evidence led to expert or consensus recommendations. Evidence certainty varies.

Newborn lesions: recognize and reassure

• These small, usually asymptomatic developmental papules generally disappear soon after birth; treatment is unnecessary. Distinguish a typical developmental cyst from a painful, ulcerated, or feeding-related presentation before reassuring the family.
• Fordyce granules: yellow-white ectopic sebaceous glands, usually on buccal mucosa or lips. The source describes them as inconsequential and requiring no management.

Restrictive frena and cleft care

• A restrictive frenum may affect feeding; possible associated concerns include poor weight gain, reflux, and prolonged feeds.
• Evaluate the mother–infant dyad with a team because breastfeeding difficulty has multiple possible causes.
• Frenectomy: consider individually for functional improvement or symptom relief. Evidence for the rationale and optimal surgical timing remains limited; base intervention on feeding function and symptoms.
• Cleft lip varies from a notch to extensive separation; it may be unilateral/bilateral and involve the alveolus. Midline cleft palate can involve the uvula, soft palate, and hard palate.
• The source reports US prevalence of cleft lip with palate around 1 in 1600 births, and isolated cleft palate around 1 in 1700.
• Arrange long-term craniofacial care. Breastfeeding often succeeds with cleft lip but usually does not with cleft palate; specialized bottles can help.
• Typical closure timing in this document: lip around 3 months, palate around 1 year. These are usual timings, not universal deadlines.

Fungal and viral presentations

• Oropharyngeal candidiasis: white plaques with erythematous mucosa; often self-limited in healthy newborns. Topical nystatin may be indicated.
• Primary herpetic gingivostomatitis: red gingiva, bleeding mucosa, clustered oral vesicles; fever, malaise, lymphadenopathy, and difficulty eating/drinking may accompany lesions. Symptoms usually regress within 2 weeks, with healing without scarring.
• Coxsackievirus: herpangina and hand-foot-mouth disease are additional causes of oral manifestations.
• The document describes presentations but provides no antiviral regimen, antifungal dose, or detailed acute-care pathway.

Natal/neonatal teeth: retain or intervene?

• Natal: present at birth.
• Neonatal: erupt during the first month.
• Usual first-tooth eruption is around 6 months.
• Early teeth generally have limited root/bony support and often belong to the normal primary dentition. Neonatal teeth occur more frequently with cleft palate.
• Retain when feeding, oral function, and aspiration are not concerns.
• Assess mobility/detachment risk, maternal nipple injury, and infant tongue trauma. Riga-Fede disease is traumatic tongue ulceration from repeated contact with the tooth.
• For feeding-related injury, options include incisal smoothing or extraction. Extraction may be warranted when mobility creates danger of detachment/aspiration.
• Teeth interfering with presurgical infant orthopedic appliances, such as nasoalveolar molding, may benefit from extraction.
• Discuss mother- and infant-specific risks, including medical/contributing factors; no numeric mobility threshold is supplied.

Retain a functional, safe tooth when possible. Assess Riga-Fede tongue injury, maternal nipple injury, and presurgical appliance interference. Mobility with detachment danger may warrant extraction; there is no numerical mobility cutoff.

Teething: safe symptom relief

• Possible symptoms: intermittent local discomfort, irritability, drooling, and low-grade fever; many children have no difficulty.
• Source options: oral analgesics and teething rings; no drug doses are specified.
• Avoid topical lidocaine or benzocaine for teething: little benefit and potentially serious harm.
• Benzocaine is contraindicated below age 2 years because of methemoglobinemia risk.
• Avoid teething jewelry, including amber necklaces: choking, strangulation, and deaths have been reported.

Feeding and caries risk

• Support breastmilk’s benefits: exclusive breastfeeding until 6 months, then continued breastfeeding as mutually desired.
• Breastfeeding and bottle use beyond 12 months, particularly frequent or nighttime use, are associated with early childhood caries (ECC). Counsel about patterns and overall risk; this is not an automatic instruction to stop breastfeeding at 12 months.
• Sugar-introduction age and exposure frequency matter. Avoid added sugars in foods/drinks under age 2; introduce no juice before 12 months.
• Low prenatal/childhood vitamin D levels are associated with greater caries experience. Prenatal supplementation may reduce offspring ECC; the source establishes no preventive dose or universal dental supplementation protocol.
• MS spreads vertically through caregiver saliva or horizontally within families/daycare. ECC causes pain, infection, reduced quality of life, and family costs.
• Include gestational age in risk assessment.
  • Preterm birth is associated with increased ECC, enamel defects/hypomineralization, and low birth weight.
  • More frequent feeding associated with low birth weight can increase caries risk; reduced immune function may favor earlier MS colonization.

Anticipatory guidance and follow-up

• Individualize prevention as primary teeth erupt: oral hygiene instruction, sugar/feeding counseling, optimal fluoride exposure, and periodic examinations.
• Assess growth/development concerns and refer to the medical provider when indicated. This document does not prescribe a fixed recall interval.
• Discuss digit/pacifier habits. Prolonged digit sucking can produce flared upper incisors, open bite, and posterior crossbite; oral effects are generally of little concern during infancy.
• Pacifier counseling: infant use is associated with reduced sudden infant death syndrome (SIDS).
  • This perinatal text also reports fewer ear infections, but the dedicated AAPD pacifier policy identifies otitis media as a risk, especially with use after 12 months.
  • Do not present ear-infection prevention as a general benefit; use the dedicated policy for age-specific counseling.
• Cover injury prevention involving play objects, pacifiers, car seats, electrical cords, and falls while learning to walk.
• Explain established caries-prevention benefits of community water fluoridation. The source identifies methodological concerns in prenatal fluoride–IQ studies and states evidence does not support reduced IQ from water at 0.7 ppm; do not generalize to every exposure level.

Common board traps

Answer aloud

A newborn has a sharp tooth and tongue ulceration. What guides treatment?

Relieve tooth-related tongue trauma while retaining the tooth when function and stability permit; aspiration risk may justify extraction.

• Confirm natal/neonatal timing and assess feeding, tongue/nipple injury, mobility, detachment risk, and appliance interference.

• A safely retained functional tooth may be managed by smoothing the sharp edge; extraction may be needed when mobility or functional harm makes retention unsafe.

• Appearance alone should not determine removal.

An infant feeds slowly and has a visible tongue-tie. Do you release it?

Not from appearance alone.

• Assess functional restriction, feeding symptoms, and alternative causes with the feeding team.
• Evidence on surgical timing is limited, so intervention should be individualized after assessing benefit, risks, and other support rather than assume that every visible tongue-tie explains slow feeding.

What do you cover at the infant’s first preventive visit?

Review the history and examine the infant, assess caries risk including relevant prematurity history, and establish a dental home by 12 months.

• Counseling should cover feeding and sugar exposure, hygiene and fluoride, common oral lesions, habits, safe teething, development, and injury prevention.
• Demonstrate caregiver home care and select counseling that fits the family's actual feeding and safety concerns.
• Give a follow-up plan matched to the infant's findings and risks, and coordinate medical or feeding-team referral when indicated.

Which teething remedies should you recommend or avoid?

Use appropriate oral analgesics or a teething ring; avoid topical anesthetics and teething jewelry.

• Topical lidocaine/benzocaine offers little benefit and potentially serious harm.
• Benzocaine is contraindicated below age two because of methemoglobinemia risk.
• Amber necklaces and other teething jewelry carry choking/strangulation risks.
• The source supplies no analgesic dose.
