If your child hates mint, switch to a mint-free toothpaste for kids in a flavour they like, such as a fruity or sweet one, and keep the fluoride. The flavour is the part you can change freely; fluoride at the right level for their age is the part that protects their teeth, so that stays.
Plenty of children find mint unpleasant, and it's not just fussiness. This guide explains why mint bothers so many kids, what to check when you choose an alternative, and how to make the switch without turning bedtime into a negotiation.
Why so many kids hate mint
When a child says their toothpaste is "spicy" or "burning", they're describing something real. Most mint toothpastes contain menthol, which acts on the cold-sensing nerve receptors in the mouth. That is why mint feels cool and tingly. Many adults enjoy that sensation. For some children it's simply too intense.
A few other things can make mint harder for kids:
- A natural sweet tooth. Children generally prefer sweeter tastes than adults, so a strong, sharp mint can taste harsh by comparison.
- Sensory sensitivities. Some children, particularly those with sensory processing differences (which are common in autistic children), find strong tastes, foam or textures overwhelming.
- Bad associations. Once brushing has become a battle, the taste of the paste can become part of what they're resisting.
The good news is that mint has nothing to do with how well a toothpaste protects teeth. That means you can change it without compromising on oral health.
What to look for in mint-free toothpaste for kids
Swapping flavour is easy. Keeping everything else right is what matters.
Fluoride at the right level
The NHS recommends fluoride toothpaste for everyone, including young children. The ppm (parts per million) figure on the pack tells you how much fluoride it contains.
| Age | How much toothpaste | Fluoride level (NHS guidance) |
|---|---|---|
| Under 3 | A smear | No less than 1,000ppm |
| 3 to 6 | A pea-sized amount | More than 1,000ppm |
| Adults | A pea-sized amount is plenty | 1,350 to 1,500ppm |
Our guide on how much toothpaste kids should use shows what a smear and a pea-sized amount actually look like.
A flavour your child chose
Offer two or three options and let them pick. A child who chose the flavour has a stake in it, which a new tube simply put in front of them doesn't.
The full ingredients list
Flavour names describe taste, not every ingredient. If you need to avoid mint entirely, for example because of an allergy or intolerance, read the full ingredients list on the pack or the Amazon listing, and ask a pharmacist if you're unsure.
Less foam, if foam is the problem
Some children object to the foamy feeling as much as the flavour. Toothpastes made without sodium lauryl sulphate (SLS) tend to foam less, so it's worth checking the label if foam seems to be the real issue.
Mint-free flavours to try
Nice Smile toothpastes come in fruity and sweet flavours rather than mint ones. The Watermelon Fresh listing describes it as leaving your mouth clean and refreshed "without harsh mint". Here's the full line-up:
- Fruity: Watermelon Fresh, Feelin' Grape and Peachy Clean.
- Sweet: Candy Clean (cotton candy), Yummy Gummy (gummy bears) and Berry Burst.
Candy Clean is a good first swap for kids who say everything is "too spicy". It's cotton candy flavoured, with fluoride, and described on Amazon as vegan, cruelty-free and enamel-safe. It comes as a single tube or a pack of four.
Not sure which one will win? The Nice Smile 3 Pack: Berry Burst, Yummy Gummy & Candy Clean puts three sweet flavours in one box, so your child can try them all. When we checked in September 2026 it was £16.69 on Amazon (£5.56 per tube), with a 4.3 star average from 99 Amazon ratings. For a side-by-side look at every flavour, see our guide to flavoured toothpaste for kids.
How to switch from mint without a fight
A new flavour works best when it's introduced as a treat rather than a fix. Try this:
- Make it a choice. "Would you like to try the candy one or the berry one?" feels very different from "here's your new toothpaste".
- Use the right amount. A smear for under-3s or a pea-sized amount for 3 to 6 year olds. Less paste also means less flavour to cope with while they get used to it.
- Try a softer brush. A small head and soft bristles can make the whole experience gentler.
- Brush together. Seeing you brush, perhaps with the same flavour, makes it feel normal.
- Keep bedtime brushing fixed. Be relaxed about the flavour, the song and who holds the brush, but keep the twice-a-day routine.
If your child resists brushing for reasons beyond the taste, our guide on how to get kids to brush their teeth has more tactics to try.
Does mint-free toothpaste clean as well?
Yes. Mint is a flavouring. It gives that "fresh" feeling, but it isn't what cleans teeth or protects them. The cleaning comes from the brushing itself, which removes plaque, and the protection comes from fluoride.
So a mint-free toothpaste with the right fluoride level, used properly, does the same job. To get the most from it:
- Brush for about two minutes, twice a day, including last thing at night.
- Spit out the excess but don't rinse with water, so the fluoride stays on the teeth.
- Don't use mouthwash straight after brushing; the NHS suggests using it at a different time of day.
When mint isn't the real problem
Sometimes switching flavour doesn't settle things. It may be worth looking a little deeper:
- Pain or sensitivity. If brushing seems to hurt, or your child flinches at cold drinks, book a dental check-up. NHS dental care is free for children.
- Gagging. A smaller brush head, less toothpaste and leaning forward over the sink can help.
- Sensory needs. If textures and tastes are generally difficult for your child, your dentist or health visitor can suggest approaches, including very mild toothpastes.
Mint-free for grown-ups too
Children aren't the only ones who find mint too much. Nice Smile is described on Amazon as kid-friendly and adult-approved, and a shared fruity flavour can make family brushing time easier. The NHS recommends adults use toothpaste with 1,350 to 1,500ppm fluoride. Nice Smile is a fluoride toothpaste, but we don't list its exact ppm here, so check the pack to make sure it suits each person in your household.
At PoundMart, we bundle Nice Smile flavours so a household can keep a few favourites on the go. You can browse every flavour and pack size in our toothpaste collection.
The bottom line
A child who hates mint doesn't need to brush with something they dread. Choose a fruity or sweet flavour they like, check the fluoride level on the pack, use the right amount for their age and keep the twice-a-day routine. Once the taste stops being the enemy, brushing gets a whole lot easier.
Frequently asked questions
Is mint-free toothpaste as good as mint toothpaste?
Yes, provided it contains the right amount of fluoride for the person using it. Mint is only a flavour; brushing removes plaque and fluoride helps protect against decay. Check the ppm figure on the pack against the NHS guidance for your child's age.
Why does my child say toothpaste is spicy?
Most mint toothpastes contain menthol, which triggers the cold-sensing receptors in the mouth and creates a tingling feeling that some children experience as "spicy" or "burning". It's a genuine sensation, not fussiness. A fruity or sweet flavour usually avoids it.
Can kids use toothpaste without fluoride?
The NHS recommends fluoride toothpaste for children from their first tooth, because fluoride helps protect teeth against decay. Fluoride-free toothpaste doesn't offer the same protection. If you have concerns about fluoride, talk them through with your dentist.
Is Nice Smile toothpaste mint-free?
Nice Smile comes in fruity and sweet flavours (Watermelon Fresh, Feelin' Grape, Peachy Clean, Berry Burst, Yummy Gummy and Candy Clean) rather than mint flavours, and the Watermelon Fresh listing describes it as fresh "without harsh mint". If you need to avoid mint-derived ingredients completely, check the full ingredients list on the pack.
