In-depth reviews

Sensodyne Pronamel Kids Enamel Strengthening Toothpaste review

Who it is for: Kids who need reliable cavity protection and have sensitive teeth or delicate mouths. If your child winces with cold water, dislikes strong flavors, or gets irritated gums, Pronamel Kids is a great starting point.

How it protects: Pronamel Kids uses sodium fluoride at about 1100 ppm to strengthen enamel and help prevent cavities. The formula is low abrasive and designed to be gentle on enamel that may be softened by acids from foods and drinks.

How it feels: The flavor is mild and not as minty as adult pastes, and the foam is soft and controlled. Kids who complain that toothpaste is spicy or stingy often do better with this formula. It is typically free of SLS, which is a common trigger for mouth irritation and can dry oral tissues.

Drawbacks: It costs more per ounce than mainstream kids pastes and the flavor is not candy sweet, which a few children find less exciting. If your child demands a strong fruit flavor or sparkles, you may need to pair this with a fun toothbrush or reward chart.

Compare it to: Compared with Crest Kid’s, Pronamel Kids is gentler and usually less foamy, which sensitive kids tend to prefer. If your child wants a fruit flavor but still needs fluoride and an SLS free base, Hello Kids Fluoride Toothpaste is the more flavorful option. For families avoiding fluoride, Risewell Kids offers a mineral approach, but fluoride remains the best studied cavity fighter for most children.

Hello Kids Fluoride Toothpaste review

Who it is for: Kids who want a fun fruit flavor without harsh foam. Parents looking for fluoride based cavity protection in an SLS free, dye free formula will appreciate Hello’s balance of gentle and kid friendly.

How it protects: Hello Kids uses sodium fluoride at about 1100 ppm, the same level dentists commonly recommend for children once they are ready for a fluoride paste. It also includes xylitol, a sugar alcohol that helps reduce the effect of cavity causing bacteria, and uses silica as a gentle polishing agent.

How it feels: This paste is low foam and not spicy, with flavors like watermelon or blue raspberry that picky kids tend to accept. The sweetness is noticeable but not syrupy. Because it avoids SLS, it is less likely to cause mouth dryness or that tight cheek feeling some children dislike.

Drawbacks: The texture can be a little looser than some pastes, so help younger kids control the amount on the brush. Very flavor sensitive children who dislike any fruit sweetness may still prefer a milder option like Pronamel Kids.

Compare it to: Hello Kids is gentler than Crest Kid’s and more flavorful than Pronamel Kids. If your child loves strawberry specifically or prefers a familiar taste, Tom’s Silly Strawberry is a close alternative with a similar gentle profile but uses sodium monofluorophosphate rather than sodium fluoride.

Tom’s of Maine Children’s Fluoride Toothpaste, Silly Strawberry review

Who it is for: Kids who want a comforting, not too sweet strawberry flavor and families who prefer simpler ingredient lists. It is a common gateway paste for children transitioning from training toothpaste to a first fluoride option.

How it protects: Tom’s Silly Strawberry uses sodium monofluorophosphate at about 1000 ppm. That still provides effective cavity protection when used twice daily. The formula avoids artificial dyes and sweeteners and is typically SLS free, which helps sensitive mouths.

How it feels: It has a soft foam and a mild, familiar taste that many kids accept on the first try. The texture leans creamy rather than jelly-like, and it rinses cleanly if your child takes a small sip of water after spitting. As with any fluoride paste, encourage spit, do not rinse, to leave a thin protective layer on teeth.

Drawbacks: Some children report a slightly chalky aftertaste. If your child wants a bolder fruit profile, Hello Kids is a better match. If sensitivity is the main issue, Pronamel Kids is a touch gentler on enamel.

Compare it to: Versus Crest Kid’s, Tom’s sacrifices bubbly foam and sparkles for a simpler recipe and softer taste. Against Hello Kids, it is similarly gentle but with a narrower flavor choice. If your child is mint averse and strawberry is the only yes, Tom’s is the easy win.

Crest Kid’s Cavity Protection Toothpaste, Sparkle Fun review

Who it is for: Families who want strong, affordable cavity protection with a familiar drugstore brand and a fun presentation. Many kids enjoy the sparkles and mild bubblegum style flavor.

How it protects: Crest Kid’s uses sodium fluoride around 1100 ppm, which is highly effective for strengthening enamel. The foaming is noticeable and helps lift plaque when kids are still learning technique.

How it feels: Expect more foam and a stronger flavor than the gentler picks above. For many kids, this makes brushing feel like the real thing and keeps interest up. For truly sensitive mouths, the SLS used for foam can sting or dry oral tissues, which is the main tradeoff.

Drawbacks: Contains SLS and artificial dyes. Children who get canker sores or complain of burning may do better with an SLS free option such as Hello Kids or Tom’s. If sensitivity is your top issue, start with Pronamel Kids instead.

Compare it to: Compared with the others, Crest Kid’s is the value workhorse with big brand consistency and an easy flavor win. Choose it if your child is not sensitive and you want maximum availability and price. If your child dislikes foam or reacts to additives, switch to Hello or Tom’s without losing fluoride benefits.

Risewell Kids Mineral Toothpaste review

Who it is for: Families looking for a fluoride free option due to personal preference or for very young children who still swallow most of the paste. It is also a good fit for kids who have reacted to multiple formulas and need something especially gentle.

How it protects: Risewell relies on hydroxyapatite, the same mineral that makes up tooth enamel. This ingredient helps rebuild weakened areas on the tooth surface and can smooth early rough spots. The formula also includes xylitol and is SLS free and dye free.

How it feels: Low foam with dessert like flavors, often cake batter or bubble gum. Kids who dislike mint often accept this immediately. The texture is smooth and easy for parents to control on the brush.

Drawbacks: Hydroxyapatite shows promising results, but fluoride remains the most proven way to prevent cavities in children. If your child has had recent cavities or is at high risk, talk to your dentist before relying on a fluoride free routine. Price per ounce is higher than drugstore picks.

Compare it to: Versus Hello and Tom’s, Risewell trades fluoride for a mineral approach that is extremely gentle and swallow friendly. For enamel sensitivity or frequent cavities, Pronamel Kids is still the better first step unless you have a specific reason to avoid fluoride.

How to choose

Start with your child’s sensitivity level. If your child complains about burning, foamy bubbles, or mouth sores, try an SLS free formula first. Hello Kids and Tom’s Silly Strawberry both skip SLS and heavy mint. If sensitivity is focused on teeth rather than soft tissues, Pronamel Kids offers a low abrasive, enamel focused formula that still keeps fluoride on board.

Match flavor to your child’s yes list. Picky brushers often refuse mint. Hello’s fruit flavors or Tom’s strawberry solve this. If your child likes classic mint, Pronamel Kids’ milder mint is a smart bridge toward adult pastes later.

Choose fluoride for most kids. Fluoride is the most proven cavity fighter. Pick sodium fluoride pastes at around 1100 ppm for ages who can spit, or sodium monofluorophosphate formulas if your dentist suggests that route. Use a rice grain smear for toddlers and a pea sized amount for kids 3 and over. If you prefer fluoride free, Risewell’s hydroxyapatite is the gentlest alternative, but consult your dentist if your child has had cavities.

Balance foam and fun. Some kids need the excitement of sparkles and bubbles to engage. Crest Kid’s provides that with a budget friendly price. If foam causes drama, an SLS free paste solves the problem overnight.

Consider price and availability. Crest Kid’s is usually the cheapest and easiest to find anywhere. Hello and Tom’s sit in the middle with approachable prices at most big stores. Pronamel and Risewell cost more per ounce. If budget is tight, start with Crest Kid’s and step down to Hello or Tom’s if irritation shows up.

Finally, do a taste test. Buy two small tubes with different flavors and let your child pick. A toothpaste that is 90 percent perfect but used twice daily beats a 100 percent perfect formula that sits untouched.

Age-by-age fluoride and brushing basics

Under 3 years: Use a smear of toothpaste about the size of a grain of rice. If your toddler swallows most of the paste, a very gentle option like Tom’s or a fluoride free pick like Risewell can help build the habit while you focus on technique. Brush for them with a soft, small brush and angle bristles toward the gumline.

Ages 3 to 6: Use a pea sized amount. Most children in this range benefit from a fluoride toothpaste like Hello, Tom’s, or Crest Kid’s. Practice spitting rather than rinsing. Spitting leaves a thin layer of fluoride on teeth for extra protection.

Ages 7 and up: Continue with a pea sized amount. If your child has sensitivity to cold or sweets, consider Pronamel Kids. Start to build independence but supervise pressure and timing. A two minute song or a simple timer helps keep brushing long enough to be effective.

Any age with sensitivity: Switch to SLS free and avoid strong mint. Use lukewarm water, choose soft bristles, and encourage gentle circular motions. If canker sores show up frequently, avoid whitening pastes and strong cinnamon. Talk to your dentist if sensitivity persists for more than a week.

Final thoughts

For most families, start with Sensodyne Pronamel Kids if sensitivity is a real issue or with Hello Kids Fluoride Toothpaste if you want fun flavors without SLS. If you need a budget classic that is easy to find, choose Crest Kid’s Cavity Protection. Strawberry loyalists often do best with Tom’s Silly Strawberry. For families avoiding fluoride, Risewell Kids is the gentlest mineral based alternative, with the reminder that fluoride remains the most proven option for cavity prevention. Pick the one your child will use twice a day and pair it with a soft brush and a simple routine.

FAQ

What fluoride level should my child’s toothpaste have for cavity prevention?

Look for kids toothpaste with about 1000 to 1100 ppm fluoride. That is usually listed as 0.24 percent sodium fluoride or 0.76 percent sodium monofluorophosphate. Use a rice grain smear for toddlers and a pea sized amount for ages 3 and up. Encourage spit, do not rinse, to leave a protective layer on teeth.

Which toothpaste is best if mint burns my child’s mouth?

Choose an SLS free, non mint option. Hello Kids Fluoride Toothpaste has gentle fruit flavors and low foam, and Tom’s Silly Strawberry is another friendly choice without harsh mint. If enamel sensitivity is also an issue, Pronamel Kids combines a mild taste with a low abrasive formula.

Can hydroxyapatite replace fluoride for my child?

Hydroxyapatite, found in Risewell Kids, can support enamel and is very gentle, which helps sensitive mouths. For children at average to high cavity risk, fluoride remains the most proven defense. If you prefer fluoride free, pair hydroxyapatite with excellent brushing habits, limited sugary snacks, and regular dental checkups.

Why does my child get mouth sores with some toothpastes?

Common triggers include SLS foaming agents, strong mint or cinnamon flavors, and whitening additives. Switching to an SLS free, dye free kids paste such as Hello Kids or Tom’s often solves the problem. If sores continue for more than a week or are severe, consult your dentist or pediatrician.

When should I move my child from training toothpaste to a fluoride paste?

Many dentists recommend switching once your child can consistently spit, often around age 2 to 3, using a rice grain smear at first. If your child has had cavities or is at higher risk, your dentist may suggest a fluoride paste earlier with close supervision. The key is a tiny amount, twice daily brushing, and spitting after.
