| Evidence strength | Moderate evidence | Strong evidence |
| Evidence Score | 3/5 | 4/5 |
| User rating | 4.5 (62) | 4.7 (738) |
| Typical dose | Caries prevention in clinical trials: usually 5–10 g of xylitol per day, split into 3–5 exposures throughout the day (most often after meals), rather than one large dose at once | 200–400 mg of elemental magnesium per day (RDA: approx. 310–420 mg depending on sex and age) |
| Form | Sugar-free chewing gum or lozenges; fluoride toothpaste with 10% xylitol as an alternative form with the best-documented benefit | Magnesium citrate, lactate or glycinate — better bioavailability than the oxide form |
| Average price | 10–25 zł za opakowanie gumy lub pastylek (ok. 30–100 porcji) | 20–45 zł za opakowanie 60 kapsułek (miesiąc stosowania) |
| Monthly cost | ok. 15–30 zł/miesiąc przy regularnym stosowaniu kilka razy dziennie | ok. 20–45 zł/miesiąc |
| Time to effects | Effects on bacterial flora (reduced S. mutans counts in saliva) can be measurable after a few weeks of regular use in laboratory studies; a hard clinical effect in the form of fewer new cavities, if present, requires observation over many months to a few years of regular use, consistent with the protocols of most clinical trials. | With an actual deficiency, improvements in well-being and sleep can be noticeable after 1–3 weeks; fully replenishing tissue stores takes longer, usually several weeks. |
| Who it's for | Parents of young children interested in early-childhood caries prevention (under guidance of a pediatric dentist) | People with a diet low in leafy greens, nuts and whole grains |
