Why Several Countries Banned Stannous Fluoride Toothpastes

Latin America and Europe are taking steps to ban the use of stannous fluoride toothpastes. Health authorities have initiated stricter regulations, while concerns about the prolonged use of this compound are growing. The goal is to protect consumers’ oral and general health from the adverse effects associated with this ingredient.

Dr. Tarsys Loayza Roys, who has reported on the latest news related to this situation, analyzes each aspect in detail. She covers everything from an explanation of the ingredient in question to the consequences and recommendations for avoiding damage.

What is Stannous Fluoride?

Stannous fluoride (SnF₂) is an ingredient used in some toothpastes. It helps reduce sensitivity and prevent cavities. However, its continuous use and use in high concentrations can have adverse effects on teeth and gums. It is obtained primarily through the reaction of metallic tin with hydrofluoric acid (HF) or by dissolving tin(II) oxide in hydrofluoric acid.

Dr. Tarsys Loayza Roys explains that in addition to its use in oral hygiene products, stannous fluoride is common in industry. She cites, for example, protective coatings, tinplate, and alloys. It has also had past uses as a marine antifouling agent, pesticide, and plastic stabilizer.

Consequences of Frequent and Excessive Use of Stannous Fluoride

1. Dental Stains and Discoloration
   Prolonged use can cause brown stains on the teeth, which are difficult to remove with conventional hygiene.
2. Irritation of Gums and Soft Tissues
   This compound can cause burning, redness, or swelling of the gums, tongue, or lips.
3. Alteration of the oral microbiome
   Some studies suggest that it alters the natural bacterial balance of the mouth, affecting long-term oral health.
4. Toxicity in children
   In children under six years of age, accidental ingestion can lead to toxic effects if consumed in excess.
   H3 Reactions from Latin American and European countries
   Countries such as Germany, Denmark, Colombia, Chile, Venezuela, and Argentina have begun to review their health regulations. They have even gone so far as to ban the sale of some toothpaste brands that contain this element in their formulas. In light of the scandal, some brands have already withdrawn products from the market or reformulated their ingredients.

What does Sonrisa Perfecta Dental recommend?

The Sonrisa Perfecta Dental clinic, based in Cartagena, recommends carefully evaluating the type of toothpaste used at home. Here are some guidelines for choosing a safe and effective toothpaste:
Key recommendations:
Verify that the toothpaste has an authorized health registration in your country.

Avoid toothpastes with high concentrations of stannous fluoride.

Prefer options with sodium fluoride, which is less harsh on teeth and gums.

If you have sensitive teeth, consult your dentist before changing products.

Do not buy toothpaste from informal or unregulated markets.

For children, always use a minimal amount and under supervision.

Check the expiration date before each use.

If you experience staining, change the toothpaste and schedule a dental appointment.

Don’t be guided by advertising alone; seek clinical support.

Schedule dental checkups every six months to evaluate your hygiene habits.
