Can adults use kids toothpaste?

Yes, adults can use kids toothpaste depending on their individual oral health needs. Even though kids' toothpaste will often come in brightly colored packaging with fun fruity flavors, it is often suitable to be used on adult teeth too!

However, some adults may require higher concentrations of remineralizing ingredients like fluoride or nano hydroxyapatite to prevent demineralization and tooth decay. In this case, kids' toothpaste may not be as suitable as adult toothpaste.

This article will explain everything you need to know about the differences between adult and kid's toothpaste and who should use them.

First, is children's toothpaste good for adults?

While children's toothpaste works for adults as well as kids, but it may not be as good as traditional adult toothpaste.

Among fluoridated toothpastes, children's toothpaste typically has a lower concentration of fluoride which means that you, as an adult, won't receive the level of remineralization potential and cavity prevention that you may need to promote healthy, strong teeth.

Further, children's toothpaste typically comes in fun flavors, like bubblegum, that may be off-putting to adults. Of course, this is of less importance that the need for an effective concentration of a remineralizing agent like nano hydroxyapatite or fluoride.

Overall, we generally recommend sticking to adult toothpaste, but if you need to use kids hydroxyapatite toothpaste in a pinch, it won't hurt you!

Adult Toothpaste vs. Kids' Toothpaste

Key differences between adult and kids' toothpaste include:

  • Fluoride concentration

  • Flavors

  • Strength

  • Added ingredients

  • Packaging

Some of these differences, such as packaging, may not influence your purchasing decision.

Others, like fluoride concentration, may be more important as they have a greater impact on your overall health.

Fluoride Concentration

Dental research suggests that kids' toothpastes have a lower concentration of fluoride as compared to adult toothpaste.

Typically, kids' toothpaste ranges from 500-550 ppm fluoride as compared to 1,000-1,500 ppm in adult fluoride toothpaste.

While still effective against cavities and tooth decay, the lower concentration is more suitable for smaller bodies and developing teeth.

For example, some studies show that too much fluoride exposure in children is associated with dental fluorosis.

Therefore, fluoride-free toothpaste is the better the option for children, and generally, kids should not use adult toothpaste.

Flavors

While you may be familiar with minty flavors in regular toothpaste, children's toothpaste often includes fun flavors.

Common flavors include:

  • Bubble gum

  • Grape

  • Strawberry

These flavors don't impact the efficacy of the toothpaste and mostly come down to personal preference.

Strength

Kids' toothpastes are typically formulated to be more gentle on the delicate tissues found in your mouth.

If you're prone to sensitivity, you may benefit from the gentle brushing experience from a kid's toothpaste formulated without sulfates or other harsh ingredients.

Added Ingredients

Some adult toothpastes are formulated with ingredients not included in kid toothpaste, such as:

  • Whitening agents

  • Anti-gingivitis ingredients

  • Peroxide

Some adults may use these ingredients to improve their oral hygiene, but they may not be suitable for children as they are more likely to swallow toothpaste.

Can adults use kid toothpaste?

Yes, adults can use kid toothpaste, but it might not be as effective at strengthening and whitening teeth as adult toothpaste.

Because kid's toothpaste often contains a lower concentration of remineralizing ingredients, it is typically not as effective as traditional adult toothpaste. Therefore, while you can use kid toothpaste in a pinch as an adult, it's best to stick with traditional nano hydroxyapatite toothpaste for adults for your every day usage.

Pros of Adults Using Kids' Toothpaste

There are some benefits to using kids toothpaste as an adult, including:
  • Fun Flavors: the fun fruity flavors may be an upgrade for adults who do not like the taste of mint toothpaste or have allergies to mint

  • Lower Fluoride: adults concerned about their exposure to sodium fluoride may want to switch to kiddie toothpaste

  • Gentler Formula: adults with sensitive tissues and gums may benefit from the gentle brushing experience found with kids' toothpaste

Further, some kids toothpastes like NOBS Jr. are formulated with nano hydroxyapatite as an effective alternative to the fluoride commonly found in adult toothpaste.

Cons of Adults Using Kids' Toothpaste

While there are some benefits to adults using kids' toothpaste, there are also some drawbacks.

For example, an adult with many cavities or extreme tooth decay may need the stronger remineralizing protection found in adult toothpaste as compared to kids' toothpaste.

Further, an adult looking for whitening benefits may not be able to find those in a child's toothpaste.

Who should stick to adult toothpaste?

Adults with specific dental concerns like gingivitis or plaque buildup will benefit more from stronger adult toothpaste as compared to kids' toothpaste.

If you have younger children and are wondering when to start brushing baby teeth with toothpaste, a good rule of thumb is around the one-year mark when their teeth begin emerging. Of course, you should stick to kids toothpaste these little ones!

Further, those looking for added benefits from their toothpaste such as teeth whitening or anti-septic agents are better served by specialized adult toothpaste formulations such as NOBS Toothpaste Tablets.

So, can kids use adult toothpaste?

No, generally, kids should not use adult toothpaste unless directed to by a pediatric dentist. Unlike how adults can use kids toothpaste, it is best for kids to use a children's toothpaste specifically formulated for them.

Further, excess tooth exposure to fluoride puts children at risk for developing dental fluorosis.Therefore, you may want to consider switching to a fluoride-free toothpaste with nano hydroxyapatite for the whole family.

Of course, cleaning newborn tongue is a different concern that brushing children's teeth, and it does not require toothpaste.

Summary: can adults use children's toothpaste?

Yes, an adult can use kid's toothpaste.

However, depending on individual oral care needs and flavor preferences, many adults will find that an adult nano hydroxyapatite toothpaste is better suited for them. This is because children's toothpaste sometimes contains a lower dosage of remineralizing ingredients, such as nano hydroxyapatite or fluoride, which prevents and reverses tooth decay.

If you're an adult considering switching to kids toothpaste, consider speaking with a dental professional for personalized advice on your circumstances before making the jump.
