Why Brushing Baby’s Teeth is Important

Taking care of your baby’s mouth should begin long before you see that first little tooth pop up. Dentists recommend scheduling your baby’s first visit at 1 year of age or within 6 months of their first tooth coming through. But why is brushing baby teeth so important, especially if they aren’t eating food yet?

First, your baby’s mouth can harbor bacteria from the sugars present in breastmilk or formula. The residue from these sugars sitting on your baby’s gums can produce bacteria. Everyone has some bacteria in their mouth, but preventing bacteria in large amounts decreases the risk of dental problems later on.

Second, establishing an early toothbrushing routine helps your baby get used to the feeling of their teeth being brushed and having a clean mouth. And we all know habits take time, so lay the foundation for good oral hygiene BEFORE the independent toddler years.

What to Look for in a Baby Toothbrush

  • Finger Toothbrushes – made of food grade silicone with small nubs and allows parents to place a finger in baby’s mouth to easily clean teeth and gums. Finger toothbrushes are very helpful prior to teething and during baby’s first few teeth.
  • Soft Bristles – easier on sensitive gums and helpful for teething babies. Introduce a soft bristled toothbrush once baby has one or more teeth.
  • Age-Appropriate Size and Shape – most baby toothbrushes have small heads that fit easily in little mouths. Also look for baby toothbrushes that have easy to grip handles with surfaces that can double as a teether.
  • Teething Toothbrushes – similar in material to finger toothbrushes, but allow baby to grip and control toothbrush for teething relief. Teething toothbrushes can be used in addition to a finger toothbrush, and should always be used with supervision.

How to Brush Baby and Toddler Teeth

Baby

Use a clean, damp washcloth or finger toothbrush and gently wipe it over your baby’s gums after a feeding. Set a goal to do this twice a day, similar to a child’s brushing schedule.

Once your baby gets their first tooth, switch to a soft-bristled toothbrush made for babies and toddlers. Most dentists recommend to keep washing your baby’s gums during this time, until more teeth come through. Continuing to clean your baby’s gums can help with discomfort as teeth continue to erupt.

When it’s time to brush baby’s teeth, lay them down on the floor or changing table. We recommend not laying them down in their crib, as we want baby to associate the crib with sleep ONLY. Laying baby down allows one hand free to help move lips and cheeks, while the other hand brushes. You may need two adults for this task, one to hold and distract your baby, while the other adult brushes. Kneel at the top of your baby’s head so you have a good view into the mouth while brushing.

Toddler

Brushing a toddler’s teeth can be a moving target (literally!). Toddlers love to exert their newfound independence in almost any situation, so have a routine and a few tips to get the job done. Most experts recommend having younger toddlers lay down on the floor for brushing – the same as you would for baby.

Brush your toddler’s teeth twice a day, typically after breakfast and right before bedtime. Use small, circular brush strokes and slowly work on increasing the amount of time spent brushing, up to 2 minutes.

Frequently Asked Questions

Do I need to brush my infant’s gums before they have teeth?

Yes, dentists recommend brushing baby’s gums before they have teeth. Even breastmilk and formula have sugars that can produce bacteria in your baby’s mouth. Cleaning your baby’s gums helps prevent bacteria from occurring in large amounts AND establishes good oral hygiene early in life.

How often should I brush my infant’s teeth?

Brush your baby’s teeth at least twice a day, similar to an older child’s brushing routine. One of those times should be after your baby’s last feeding and before bedtime. This will prevent milk or food from sitting on gums and teeth overnight.

Should I keep brushing my baby’s gums after their first tooth arrives?

Once your baby’s first tooth erupts, you can continue cleaning your baby’s gums until more teeth have erupted. Continuing to brush your baby’s gums can help relieve discomfort from teething and encourage tooth eruption.

Should I use toothpaste on the toothbrush?

Initially, you can simply use water on a soft-bristled toothbrush for your baby’s first few teeth. Once several teeth erupt, add a tiny amount of toothpaste (i.e. the size of a grain of rice). Continue to use this tiny amount of toothpaste for your toddler, up until about age 3. At this age, toddlers begin to understand the concept of spitting the toothpaste out. Toddlers 3 years and older can start to use a pea-sized amount of toothpaste.

Can babies use fluoride toothpaste?

Previously, dentists recommended that children under 2 years use fluoride-free toothpaste. In 2014, The American Academy of Pediatrics updated guidelines to allow for the use of fluoride toothpaste for all ages, if used sparingly and under parental supervision. Since babies cannot purposefully spit out toothpaste, use a grain-sized amount of toothpaste during this time. If you have concerns about fluoride toothpaste, discuss it with your pediatrician or dentist.

Should I let my toddler use an electric toothbrush?

Electric toothbrushes can be a motivating way to get your toddler interested in toothbrushing. Some toddlers love the added stimulation that electric toothbrushes provide. Other toddlers may be overwhelmed by the noise and vibration. Some dentists suggest that electric toothbrushes be used for ages 3 years and older, but even younger toddlers may benefit from using one. Just remember that an electric toothbrush is not a substitution for parental assistance with toothbrushing.

Tips on How to Make Brushing Fun

  • Model good brushing – let your toddler see you brushing your teeth often.
  • Brush teeth in the bathroom – with busy toddlers, it’s easy to fall into the habit of chasing your little one. Set the expectation for brushing teeth in the bathroom. Use a towel or small mat on the floor for comfort as needed.
  • Use a predictable pattern – brush in a consistent way to let your toddler know what to expect with each brushing. For example, brush left to right, and bottom to top.
  • Talk about what you are doing – tell your toddler what’s going to happen. For example, “first we’re going to brush your bottom teeth, next we’re going to brush…”
  • Make it fun – sing songs or count aloud in a silly voice. Create your own toothbrushing dance or watch a video of a favorite character brushing their teeth.
  • Take turns – allow your toddler to have some turns with a toothbrush that they can hold. Adults can take turns brushing with a second toothbrush.
  • Use the mirror – some toddlers do better when they can see where the toothbrush is going. Consider having a second adult hold a small mirror or let your toddler stand in front of a mirror to brush.
  • Stay calm – your little one can sense if you’re starting to get frustrated. Try your best to relax and remember that building the foundation for good toothbrushing habits takes time.

Best Toothbrushes for Baby and Toddlers

Our favorite baby and toddler toothbrushes have soft silicone or nylon bristles to easily clean teeth and gums. We recommend starting with the Mushie Baby Finger Toothbrush or Banana Infant Toothbrush for infants and younger toddlers. Once your little one gets more teeth, you can switch to one of the soft nylon-bristled brushes for better coverage.
