When my kids were babies, I wanted to give them an edge up on good oral hygiene right from the start. That involved wiping their gums with a damp cloth after feeding and giving them a chance to “brush their own teeth” with a silicone baby “toothbrush” teether.

My dad the dentist told me stories of kids coming to his office with rotting teeth that he had to refer to a pediatric oral surgeon. That can be a traumatic experience for any kid – prevention is the best cure when it comes to the oral health of your children.

When To Start Brushing Baby Teeth?

  • Before the first tooth emerges, take either a damp washcloth, a piece of gauze, or a silicone finger brush and gently swipe around the gums after eating and at bedtime. This will help your baby get used to the act of brushing while also removing food particles.
  • Start brushing your baby’s teeth as soon as the first tooth pokes through the gums. Make sure the toothbrush you purchase has extra soft bristles and a small head that you can easily navigate around your child’s mouth.
  • First tooth eruption varies with every baby, but it can happen as early as 3 months or even before, and up to 12 months or later. Visit your dentist if you’re concerned about teeth not coming in by 18 months. All 20 baby teeth will usually come in by 3 years of age. Between 6 and 20 years of age, 32 teeth will come in as permanent teeth.

Best Practices For Babies And Toddlers

  • Avoid baby bottle decay Don’t put your baby to bed with a bottle of juice, milk or formula. These liquids all contain sugar that can coat the teeth and gums, feeding the bacteria that causes tooth decay.
  • Limit juice and other sugary drinks Kids don’t need juice on a regular basis – water is more than okay to sip on throughout the day.
  • Brush After Sugary Medicine I’m not saying to get your kids up in the middle of the night to brush after taking medicine, but children that take long-term sugary medication should brush after they take a dose.

How Much Toothpaste Should Kids Use?

  • Birth to 3 years old: a dollop no larger than a grain of rice. Technically, babies and kids under 2 don’t need toothpaste – the act of brushing itself removes plaque and food particle build-up.
  • Age 3 and older: a pea-sized amount
  • Teens: A thin ribbon of toothpaste across the bristles

Have your kids brush for two minutes twice per day and floss once daily. Monitor children until you feel they have a good handle on how to care for their teeth on their own. My dad the dentist made up a song that he sang while we brushed our teeth, and I also used that song while my own children brushed.

There are apps and songs (BrushDJ, Disney Magic Timer, Brush Teeth With The Wiggles) that will entertain your child for 2 minutes while they brush. I’ve also attached a Youtube video at the end of this post that features 2 adorable British kids teaching other children the proper way to brush.

What’s Wrong With Fluoride?

  • According to the Centers for Disease Control (CDC), almost 40% of children age 3-6 use too much toothpaste. Since kids at this age are most likely not spitting it all out, the toothpaste, along with the added fluoride, ends up getting accidentally ingested.
  • Ingestion of too much fluoride while teeth are developing can result in dental fluorosis (discoloration and pitting of the enamel).
  • A 2017 study in Mexico found that the offspring of women with a high prenatal fluoride exposure had lower scores on cognitive function tests between the ages of 4 and 12 years old.
  • According to a 2012 review that included 27 studies, children residing in areas of the country with high fluoride drinking water levels had significantly lower IQ scores than those who resided in areas of the country with lower fluoride drinking water levels.
  • High levels of fluoride in pregnant women can cause nervous system damage to the fetus.
  • The National Toxicology Program concluded that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children.

As the studies above indicate, there are health issues associated with ingestion of too much fluoride. The best solution is to use a fluoride-free toothpaste for kids.

Just as using natural and non-toxic toothpaste is important for your child’s health, look for kids bath products that are free from harmful ingredients, including non-toxic lotion and natural deodorant for kids.

Hydroxyapatite: A Safe Fluoride Alternative

What Kind Of Hydroxyapatite Do You Recommend For Kids?

Most of the kids toothpaste brands below contain micro hydroxyapatite (Risewell, Happy Tooth and Wellnesse). Micro Ha has a particle size of five to 10 microns. It does not contain nano particles. If your child has strong enamel and has never had a cavity, micro hydroxyapatite is a great choice for their daily toothpaste needs. For children that are prone to cavities and tooth decay, nano hydroxyapatite is more effective at penetrating tooth enamel than micro hydroxyapatite (Fygg).

Do All Of The Toothpaste Brands You Recommend For Kids Contain Hydroxyapatite?

No. All of the baby and toddler toothpaste brands that I recommend do not contain hydroxyapatite, and one of the kid brands (Attitude) does not contain hydroxyapatite.

What is Nano Hydroxyapatite?

Nano hydroxyapatite consists of rod or needle shaped particles with a size ranging from 20 nm to 100 nm. When comparing nano HA to micro HA, nano-HA is more effective at binding to surfaces better, and this enhances remineralization of the teeth while also reducing tooth sensitivity. 

Is Nano Hydroxyapatite Safe?

The European Union Scientific Committee on Consumer Safety (SCCS) has spent the last 8 years systematically reviewing the research on nano-HA. The SCCS is an independent panel made up of experts in the field of toxicology, as well as pathology, biochemistry, chemistry and physics. They oversee the safety of cosmetics and consumer goods and investigate whether chemicals and ingredients pose safety risks.

Their final opinion after 8 years of research on nano-HA is that it is safe when used at concentrations up to 10% in toothpaste, and up to 0.465% in mouthwash. Nano-HA must be composed of rod-shaped particles of which at least 95.8% (in particle number) have an aspect ratio less than 3, and the remaining 4.2% have an aspect ratio not exceeding 4.9. Also, the particles cannot be coated or surface modified.

There is one lab in Portugal, Fluidinova, that synthesizes nano-hydroxyapatite in the proper formation that the SCCS endorses. Nano-HA made by Fluidinova is used in the products I recommend.

Ingredients To Avoid In Toothpaste

  • Triclosan– Triclosan is an antibacterial agent that’s linked to bacterial resistance and endocrine disruption.
  • Sodium lauryl sulfate (SLS)– this is associated with canker sores and perioral dermatitis (my daughter is susceptible to this hard-to-eradicate rash around the mouth).
  • Artificial colors– Who needs blue toothpaste if it’s linked to hyperactivity in kids?
  • Parabens– These preservatives prevent the growth of bacteria, but they disrupt hormone function and were able to stimulate breast cancer cell growth in a lab study.
  • Propylene glycol– Propylene glycol is used to make personal care products thicker and better able to transport moisture to the skin. The manufacturing process introduces impurities and by-products, such as ethylene oxides and 1,4-dioxane, which are known carcinogenic materials (8).
  • Strong Antibacterial Essential OilsAccording to Dr. Mark Burhenne, while essential oils may work to kill off some of your “bad” oral bacteria, strong essential oils may also kill off some of the beneficial bacteria in your mouth, disrupting your oral microbiome.

Fluoride-Free Toothpaste For Teens

My kids are now teens, and it goes without saying that bad breath is not acceptable in any peer group.
