Early childhood caries (ECC) is tooth decay in children from birth up to about 6 years old. It can involve one or more decayed, missing, or filled primary teeth.

What causes ECC
- Bacteria such as Streptococcus mutans and Lactobacillus live in the mouth. They pass from caregiver to child and start decay.
- These bacteria produce acids when they mix with sugars from foods and drinks. The acids damage tooth enamel and trap minerals, leading to cavities.
- Plaque, a film on the teeth, helps bacteria grow. Nighttime bottle feeding or long exposure to sugary drinks increases acid attack because saliva is lower at night.

Who is at risk
- Children from lower-income families or with less access to dental care.
- Diet high in sugary drinks and snacks; frequent snacking.
- Poor tooth cleaning or not using fluoride properly.
- Enamel problems (enamel hypoplasia) or other health issues.

What ECC looks like and why it matters
- Decay can start with white spots and progress to visible holes.
- It can cause pain, trouble eating or sleeping, and may require fillings, crowns, or tooth extractions.
- Early decay can affect a child’s quality of life and long-term dental health.

Prevention ideas that help a lot
- Start before birth: a healthy diet for mom during pregnancy supports growing teeth.
- After baby is born:
- Brush teeth twice daily with a small amount of fluoride toothpaste (smear for kids under 3; pea-sized for ages 3–6). Adults should supervise until about age 6.
- Do not let a child sleep with a bottle of milk, juice, or sugary drink. Introduce a cup around 12 months.
- Limit sugary drinks and snacks; encourage water and healthy foods.
- Visit a dentist regularly starting by the child’s first birthday.
- Fluoride helps protect teeth; use fluoride toothpaste correctly.
- If a child has enamel problems or is at higher risk, a dentist may use additional protective fluoride treatments.

What dentists can do
- For early, mild decay: focus on prevention and monitoring.
- For more decay: restore teeth or protect them with special crowns. Newer methods include:
- Stainless steel crowns (often used for multiple decay on baby teeth).
- Hall Technique (placing a crown without removing decay first).
- Atraumatic Restorative Treatment (ART): filling with simple materials using hand tools.
- Silver Diamine Fluoride (SDF): stops decay quickly and without drilling, but can stain the treated areas. SDF is inexpensive and easy, which helps kids who have trouble staying still. In many cases, a future filling or crown may still be needed.
- Severe cases under anesthesia are possible but are less common and carry other risks; dentists aim to treat early to avoid these.

Key takeaways
- ECC is common but preventable. Good diet, proper brushing with fluoride, and early dental visits greatly reduce risk.
- Start dental care early (ideally by the first birthday) and keep regular checkups.
- If you notice white spots or new decay, or if brushing is difficult for your child, talk to a dentist right away to stop problems from getting worse.
