For daily use, choose a toothpaste containing at least 1350–1500 ppm fluoride with an abrasivity value (RDA) of 70 or lower. Fluoride is the key ingredient that prevents tooth decay. For sensitive teeth, choose pastes with potassium nitrate or strontium chloride; for bleeding gums, antibacterial pastes. Whitening toothpastes should be used in rotation, not continuously.
- Fluoride strengthens tooth enamel.
- A low RDA value is safer for protecting enamel.
- Whitening toothpastes are usually abrasive.
- Toothpaste is only an aid; correct brushing and flossing do the real cleaning.
1. The Essential: Fluoride Content
Unless a medical condition indicates otherwise, the only ingredient that prevents tooth decay is fluoride. To strengthen your tooth enamel, make sure your toothpaste contains at least 1350–1500 ppm fluoride.
2. Choose According to Your Needs
-
Sensitive Teeth: If you have sensitivity to hot and cold, choose toothpastes containing potassium nitrate or strontium chloride that soothe the nerves.
-
Gum Health: If your gums bleed, opt for gum-protecting toothpastes with antibacterial properties (usually herbal or containing zinc citrate).
-
For Those Who Want Whitening: "Whitening" toothpastes are usually abrasive. To avoid damaging your enamel, you should use these toothpastes in rotation, not continuously.
3. Pay Attention to Abrasivity (RDA)!
The abrasivity of toothpastes is measured by RDA. For daily use, toothpastes with an RDA value of 70 or lower (low abrasivity) are the safest choice for protecting tooth enamel.
Important Note: Toothpaste is only an aid. Correct brushing technique and dental floss are what really do the cleaning.
