What Every Parent Should Know About Baby Teeth

Your Child’s First Dental Visit

Visiting the dentist is another important milestone in your child’s early years. The American Academy of Pediatric Dentistry recommends scheduling your child’s first dental visit within one year of their first tooth erupting, or by age one. Early visits help build familiarity, support healthy habits, and allow us to prevent issues before they begin.

After the first visit, most children return every six months unless more frequent visits are recommended. Regular checkups help keep your child’s smile healthy as they grow.

​

What to Expect During a Pediatric Dental Visit

• A gentle exam of your child’s teeth, gums, and oral development

• Counting teeth and monitoring eruption patterns

• Guidance on brushing, nutrition, and daily care routines

• Preventive treatments such as fluoride varnish or sealants when appropriate

Our goal is to make each visit comfortable, positive, and age-appropriate.

When to Start Brushing and Flossing Baby Teeth

Cavities can begin as soon as the first tooth appears. Once your child’s first tooth erupts, it’s time to begin brushing twice daily—morning and bedtime. As teeth touch, flossing should be introduced to help prevent cavities between teeth.

Young children often need help brushing until they develop the coordination to do it well on their own.

​

Helping Children Build Healthy Brushing Habits

Children learn best by example. Brushing together and keeping routines consistent can help establish lifelong habits.

• Help your child brush and floss daily

• Continue assisting until at least age 6

• Most children cannot brush effectively on their own until around age 8

• Brush for two minutes using a soft, child-sized toothbrush and fluoride toothpaste

A helpful rule of thumb: if a child can’t tie their shoes, they likely still need help brushing.

​

Tips for Showing Children How to Brush Their Teeth

• Under age 2: use a small smear of fluoride toothpaste

• Ages 3–6: use a pea-sized amount of fluoride toothpaste

• Brush twice daily for two minutes

• Hold the toothbrush at a gentle 45-degree angle toward the gumline

• Clean all surfaces of the teeth​

Why Baby Teeth Are More Prone to Cavities

Baby teeth have thinner enamel than adult teeth, which makes them more susceptible to cavities. Cavities are caused by bacteria that convert sugars into acids, gradually weakening tooth enamel.

Good oral hygiene and healthy habits help protect baby teeth and reduce the risk of decay.

​

How Cavities Can Be Transferred

Babies are not born with cavity-causing bacteria. These bacteria are often passed from caregivers through shared utensils, cleaning pacifiers with the mouth, or kissing on the lips. Practicing good oral hygiene as a parent helps protect your child’s teeth as well.

​

How Fluoride Helps Protect Baby Teeth

Fluoride helps strengthen tooth enamel and makes teeth more resistant to decay. It’s commonly found in toothpaste and drinking water and plays an important role in protecting both baby and adult teeth.

​

How Drinking Water Helps Prevent Cavities?

Fluoridated water is one of the easiest ways to support dental health. Water helps rinse away food particles, keeps the mouth hydrated, and strengthens teeth—making it the healthiest beverage choice for children.

​

Dental Sealants: Extra Protection Against Cavities

Dental sealants are thin, protective coatings placed on the chewing surfaces of molars. Sealants create a barrier that helps prevent cavities in areas that are harder to clean with brushing alone. Studies show that sealants significantly reduce cavity risk in school-age children.

​

How Nutrition Affects Your Child’s Dental Health

A balanced diet supports strong teeth and healthy development. Sugary foods and drinks can increase the risk of cavities, especially when consumed frequently.

Helpful tips for reducing sugar exposure:

• Read food labels and limit added sugars

• Encourage water as the primary drink

• Transition from sippy cups to regular cups by age one

• Offer nutritious snacks and limit sweets between meals

​

Why Nighttime Bottle Use Can Harm Baby Teeth

Putting a baby to bed with a bottle containing milk, juice, or sweetened drinks allows sugar to remain on the teeth for long periods. This can lead to tooth decay, especially on the front teeth. Encourage finishing bottles before bedtime and avoid sugary drinks at night.

​​

Pacifiers and Thumb-Sucking: Effects on Baby Teeth

Pacifier use and thumb-sucking are common in young children. However, prolonged habits can affect tooth alignment and jaw development. The American Academy of Pediatric Dentistry recommends stopping these habits by around age 3. If habits continue, your dentist can help guide next steps.

​

Breastfeeding and Baby Teeth

Breastfeeding supports overall health and development and does not cause cavities on its own. However, if a child falls asleep while nursing after teeth have erupted, milk may remain on the teeth. Gently cleaning the mouth after feeding and encouraging water at night can help protect teeth.

​

In Closing

Even though baby teeth eventually fall out, they should be cared for as if they were permanent. Healthy habits, regular dental visits, and supportive guidance help protect your child’s smile and set the stage for lifelong oral health.
