Which toothpaste is the best? How to choose a toothpaste consciously

The toothpaste aisle can feel like the skincare section of a beauty store these days.

Remineralizing. Whitening. Sensitive. Natural. Fluoride-free. With hydroxyapatite. SLS-free. Gum care. With enzymes.

Which one to choose?

The most important rule is: there is no single best toothpaste for everyone.

A good toothpaste is one whose ingredients meet your actual needs.

1. First, determine what you need

Before you start analyzing the ingredients, answer one question:

what problem is the toothpaste supposed to solve?

For one person, the priority will be caries prevention, for another, sensitivity, and for another, recurring mouth ulcers or coffee stains.

This is a much better starting point than choosing a product based on the packaging or the intensity of the flavor.

2. Fluoride – still the most important benchmark in caries prevention

Fluoride is one of the most thoroughly studied ingredients used in caries prevention.

The ADA recommends brushing twice daily with a fluoride toothpaste, and typical over-the-counter fluoride toothpastes contain about 1000–1500 ppm of fluoride.

This does not mean, however, that every toothpaste must be identical. The market is also developing alternative technologies, including hydroxyapatite, to which we have dedicated separate articles on the Dentistique blog.

3. Hydroxyapatite

Hydroxyapatite is a biomimetic mineral used in products for remineralization and sensitivity reduction, among other things.

Clinical data indicate, among other things, its potential in reducing dentin hypersensitivity.

4. SLS – pay attention especially in case of mouth ulcers and irritation

SLS is responsible for, among other things, the foaming of the toothpaste.

For most people, its presence is not a problem.

However, in patients with recurring mouth ulcers, studies indicate that using SLS-free toothpastes can reduce the number and severity of lesions. The data are promising, although still limited. More on this topic: SLS-free toothpaste – what does it mean and for whom is it a good choice?

If you often get mouth ulcers, it is worth considering trying an SLS-free toothpaste.

5. Sensitivity – look for an active ingredient

For sensitivity, the word "Sensitive" on the label is not enough.

Studies have shown good results for several groups of substances, including:

• hydroxyapatite,
• stannous fluoride,
• potassium compounds,
• arginine,
• calcium sodium phosphosilicate.

6. And what about RDA?

RDA stands for Relative Dentin Abrasivity and is a standardized way of measuring the abrasivity of a toothpaste relative to dentin.

However, there are many oversimplifications surrounding RDA.

The ADA indicates that toothpastes with an RDA of up to 250 meet established safety criteria, and values below 250 should not be treated as a simple "the lower, the safer" scale.

This is important because many arbitrary tables can be found online that divide toothpastes into "safe" and "unsafe" based solely on their RDA.

In practice, the brushing technique, pressure, and the condition of the tooth tissues also matter.

7. Whitening toothpaste – what can you expect from it?

Most toothpastes labeled as whitening act primarily on external deposits and surface stains.

You should not expect the same level of tooth color change from a toothpaste as you would from professional whitening methods.

When choosing a product, it is worth paying attention to its mechanism of action and its abrasivity.

Is a more expensive toothpaste better?

Not always.

The price may be due to the quality of ingredients, production technology, research, brand, or product positioning.

But a 70 PLN toothpaste will not automatically be seven times better than a 10 PLN product.

At Dentistique, we look primarily at:

ingredients, the logic of use, available data, and the quality of the entire formulation.

The simplest way to choose a toothpaste

If you have healthy teeth and a low risk of caries – go for a well-researched toothpaste for daily use.

If you have a specific problem, choose the active ingredient for that problem.

Sensitivity? Look for desensitizing ingredients.

Mouth ulcers? Consider an SLS-free toothpaste.

Stains? Look for a product designed for their controlled removal.

Remineralization? Pay attention to fluoride, hydroxyapatite, and other remineralizing technologies.

And remember: a good toothpaste is important, but it will not replace proper, regular brushing.
