How to Brush Baby Teeth

As a pediatric dentist, I've seen firsthand how early dental care shapes a child's oral health journey. Let me share my expertise on maintaining your baby's dental health from day one.


Starting Early

Pre-Tooth Care Even before teeth emerge, oral hygiene matters. Clean your baby's gums daily with a soft, damp cloth after feedings. This removes bacteria and gets them comfortable with oral care routines.


How to Brush Baby Teeth: When to Begin Brushing

Start brushing as soon as you spot that first tooth, typically around 6 months. Use an infant-specific toothbrush with ultra-soft bristles. Begin with water only, introducing a rice-grain sized amount of fluoride toothpaste when multiple teeth appear.


Proper Technique

  1. Position your baby comfortably in your lap or on a changing table

  2. Use gentle, circular motions on all tooth surfaces

  3. Clean the gum line where bacteria often accumulate

  4. Spend about 2 minutes total, focusing on both front and back teeth


Getting Baby to Cooperate

From my clinical experience, these strategies work best:


  • Make brushing playful with songs and games

  • Demonstrate on yourself or a favorite toy

  • Use gentle cheek strokes to encourage mouth opening

  • Maintain a consistent routine morning and night

  • Praise cooperation to build positive associations


Remember, every baby responds differently to tooth brushing. Stay patient and consistent with these techniques, adjusting as needed for your child's comfort level.


Best Practices

  • Brush twice daily

  • Replace toothbrush every 3-4 months

  • Schedule first dental visit by age 1

  • Monitor for signs of tooth decay

Getting Baby to Open Their Mouth

Getting your baby to cooperate during tooth brushing can be challenging, but there are several effective techniques you can try:


  1. Make it playful by turning brushing into a game. Demonstrate opening your own mouth wide like a lion or make funny faces to encourage your baby to mimic you.

  2. Sing songs or create a special brushing tune that signals it's time to open wide. This helps establish a fun routine your baby can anticipate.

  3. Let your baby hold a second toothbrush while you brush their teeth. This gives them a sense of involvement and control in the process.

  4. Gently stroke your baby's cheek or tap their chin to encourage them to open their mouth. Most babies naturally open their mouths in response to these gentle touches.

  5. Show them the process on a favorite stuffed animal or doll first, making it both familiar and entertaining.

  6. If your baby is resistant, try brushing while they're reclined in your lap. This position gives you better visibility and control while keeping your baby comfortable.

  7. Use positive reinforcement by praising your baby when they cooperate, making the experience more rewarding.


Remember to stay patient and consistent. Some days will be easier than others, but maintaining a positive attitude helps your baby develop a healthy relationship with oral care.


Choosing the Right Tools

Selecting the appropriate tools is crucial for effective and comfortable brushing of your baby's teeth. Here are some key considerations:


How to Brush Baby Teeth

Toothbrush Selection

  1. Opt for a soft-bristled toothbrush with a small head that fits comfortably in your baby's mouth. Both manual and electric toothbrushes can be effective.

  2. Look for toothbrushes with the American Dental Association (ADA) seal of approval, as they meet safety and quality standards.

  3. Avoid silicone or finger brushes, as they are not as effective at removing plaque.

  4. Steer clear of U-shaped "retainer-style" brushes, as studies show they are not as efficient.


A few recommended toothbrushes:


Toothpaste Selection

Age Range

Toothpaste Amount

Fluoride Content

0-18 months

How to Brush Baby Teeth

Toothpaste with fluoride is recommended to strengthen teeth and prevent cavities. For babies and toddlers who cannot reliably spit, use a rice grain amount of fluoride toothpaste twice a day. For children who can spit, use a pea-sized amount of fluoride toothpaste.


Recommended Toothpaste Options:


Brushing Technique

Establishing proper brushing techniques from an early age is crucial for maintaining good oral hygiene and preventing dental issues. Here are some key points to keep in mind when brushing your baby's teeth:


Gentle Circular Motions

  1. Use a soft-bristled toothbrush designed for infants and gently brush in small circular motions.

  2. Brush all surfaces of the teeth, including the front, back, and chewing surfaces, as well as along the gum line.

  3. Spend approximately two minutes brushing, ensuring thorough coverage of all tooth surfaces.


Post-Brushing Routine

  1. After brushing, encourage your child to spit out any excess toothpaste, but do not rinse with water.

  2. Leaving a small amount of toothpaste in the mouth helps the fluoride continue protecting the teeth.

  3. Rinsing immediately after brushing can wash away the beneficial effects of the fluoride.


Remember, consistency is key when it comes to establishing good brushing habits. Make brushing a fun and positive experience for your child by incorporating songs, stories, or letting them hold their own toothbrush while you brush their teeth.


Introducing Toothbrushing

Making toothbrushing a fun and engaging experience for your baby is key to establishing good oral hygiene habits early on. Here are some tips to help introduce toothbrushing in a positive way:


1. Make It a Game

Turn brushing into a playful activity by taking turns, involving your child's favorite toy, or playing music. Sing a song to make it more engaging for infants and toddlers. This helps create a positive association with brushing.


2. Let Them Explore

Allow your toddler to hold and explore their toothbrush before you start brushing. Let them "brush" a toy or their own teeth first. This helps them feel more in control and comfortable with the process.


3. Use the "Knee-to-Knee" Technique

If your baby resists having their teeth brushed, try the "knee-to-knee" technique. Sit facing another adult, with your knees touching, and have the other person hold and comfort your baby while you gently brush their teeth. This can help keep them calm and secure.


Remember, establishing good oral hygiene habits from an early age is crucial for your child's overall health and development. By making toothbrushing a fun and positive experience, you'll set the foundation for a lifetime of healthy smiles.


How to Brush Baby Teeth

Transitioning to Independent Brushing

As your child grows older, it's important to encourage their participation in brushing and gradually transition them towards independent brushing. Here's how you can approach this process:


Encouraging Participation

  1. Around age 2-3, start involving your child in the brushing routine. Let them hold the toothbrush and guide their hand to brush their own teeth.

  2. Make it a fun activity by singing songs, telling stories, or using a toothbrushing app to keep them engaged.

  3. Praise and encourage their efforts, even if they don't do a perfect job. This will build their confidence and motivation.

Supervision and Assistance

While your child may show interest in brushing independently, it's crucial to continue supervising and assisting them until they can do it effectively, usually around age 7-8.

Age Range

Supervision and Assistance

2-3 years

Involve child in brushing, but provide full assistance

4-6 years

Allow child to brush first, then assist by re-brushing thoroughly

7-8 years

Supervise and provide guidance, but let child take the lead


Dental Check-ups

Remember to schedule your child's first dental check-up by age 1 or when that first tooth pops up. Regular visits to the pediatric dentist will not only monitor their oral health but also reinforce the importance of good brushing habits.
