Pasta de dientes: ¿Mejor con flúor o sin flúor?

¿Pasta de dientes con flúor o sin flúor? Sin duda, esta es una de las grandes cuestiones en cuanto a higiene bucodental, por lo que conocer sus diferencias es fundamental para elegir dentífrico

Pese a ser un tema en el que rara vez se piensa a la hora de elegir pasta de dientes, algunos de estos productos pueden llegar a ser incluso peligrosos si no se analiza su composición. Sin embargo, es un eterno debate en lo que a hábitos de salud bucodental se refiere: ¿Es mejor la pasta de dientes con flúor o sin flúor?

¿Qué es el flúor?

Para arrojar luz, primeramente es vital saber qué es el flúor. Se trata del elemento químico más reactivo de toda la naturaleza. Sin embargo, no es posible encontrarlo como tal en los ecosistemas, sino que se trata del componente central de los fluoruros.

Estos fluoruros están, prácticamente, en todas partes: en el suelo, en el aire, en el agua o incluso en algunas plantas y animales. Generalmente son incoloros, y se pueden encontrar en estado sólido, líquido y gaseoso. Se liberan en el medio ambiente a través de la meteorización y disolución de minerales, las emisiones de volcanes y los aerosoles marinos.

Pero la naturaleza no es la única capaz de fabricar estos compuestos. La acción humana, a través de la combustión de carbón, las aguas industriales, la fabricación del acero, la producción de aluminio o la fabricación de fosfatos, contribuye a las principales fuentes industriales de emisiones de fluoruros en el medio ambiente.

Actualmente, este compuesto se ha hecho muy popular en el agua potable o en productos dentales, ya que ayuda en la prevención de las caries.

¿Pasta de dientes con flúor o sin flúor?

Existen diferentes puntos de vista sobre si es más recomendable la pasta de dientes con flúor o sin flúor.

  • Aquellos defensores basan sus argumentos en que el flúor es una sustancia que ayuda a reducir las caries.
  • Sus detractores cuestionan si sus beneficios son más o menos importantes que sus potenciales peligros.

Lo que está claro y demostrado es que todo en exceso es malo, y eso mismo pasa con el flúor, ya que su consumo desmesurado puede llegar a ser muy peligroso.

¿Cuáles son los pros y contras de los dentífricos que lo contienen?

Los dentistas y marcas de pasta de dientes defienden que, en las cantidades adecuadas, este mineral natural se absorbe por los huesos y los dientes, concentrándose durante el desarrollo para fortalecer el esmalte y sus estructuras.

Pros

Según corroboran diversas marcas expertas, como es el caso de Oral-B, la intervención del flúor frena la velocidad de descomposición del esmalte dental. De tal modo, el nuevo esmalte que se origina como pequeños cristales son más grandes y resistentes a sustancias como el ácido.

El flúor dental también trabaja en los procesos de desmineralización y remineralización de la boca, reponiendo el calcio y el fósforo que conservan la fortaleza de los dientes. Se alcanza entonces un punto muerto en el que no queda muy claro si es más beneficioso que perjudicial, o viceversa. Está claro y demostrado que reduce de forma eficaz la aparición de las caries, pero con el tiempo y un uso excesivo, pueden aparecer manchas y problemas asociados a los huesos y los dientes.

Contras

Principalmente, estos serían algunos de los riesgos principales del uso de dentífricos con flúor:

  • Es el causante de afecciones como la fluorosis esquelética, derivada de la acumulación excesiva en los huesos que provoca cambios en su estructura, volviéndolos frágiles y quebradizos.
  • La fluorosis dental, que aparece como resultado a la ingesta desproporcionada de este elemento durante el periodo de desarrollo de los dientes.
  • Otro de sus riesgos es que el flúor disminuye el yodo en el cuerpo, afectando a las funciones tiroideas que favorecen que engordemos, estemos más cansados, sintamos un menor deseo sexual o tengamos frío a todas horas.

Claro que hay que tener en cuenta que, como todo lo que posee intereses comerciales, sus beneficios y contradicciones están también argumentadas de una u otra forma y son más o menos destacadas si se pregunta a unos u otros.

La conclusión es que no se puede definir si unas son mejores que otras. A fin de cuentas, consiste en buscar aquel producto que mejor se adapte a las necesidades específicas. Y, en caso de ser una pasta de dientes con flúor, se deberá vigilar la cantidad mínima recomendada en cada cepillado. Lo cierto es que con una pizca de dentífrico es suficiente para un cepillado idóneo.
