Fluoride, poisonous?

The use of fluoride is a constantly talked about topic, particularly when it comes to the practice of water fluoridation. This Irvine sedation dentist will tell you Fluoride can be a wonderful thing in terms of remineralization of your enamel. I offer fluoride treatments in the office. However, incorporating fluoride into water is a controversial issue that gets countries talking.

Fluoride was first introduced in the USA in the 1940s after the discovery that fluoride helps strengthen teeth and oral health. This is the reason why many types of toothpaste incorporate this element, and why dental organizations like the ADA believe drinking water with Fluoride can help teeth—the same way toothpaste does. Following the World Health Organization’s 1969 endorsement countries around the world began fluoridating their drinking water.

However, Fluoride’s popularity began to wane from the 70s to the 90s when some European countries, such as Germany, Sweden and Finland, reversed their stance on the practice of fluoridation. Exact reasons were not given, but sources proclaimed not enough benefits were found or that it wasn’t worth the risk of poisoning. Who knows what the real reasons were?! The only thing that this Irvine sedation dentist can you tell you is that fluoride can indeed be poisonous. However, we have to keep in mind a lot of things we potentially ingest has the same or similar risk. For example: alcohol, mercury in fish (sushi , anyone?), and even magnesium in antacids. Overdosing is possible and in some areas of the US, there are instances of poisoning. Some effects include weakening of bones and corrosion of teeth. On the other hand, it can bring plenty of benefits. The bottom line is there needs to be a balance and general awareness of fluoride ingestion…therefore, the debate continues.

1) True or False: Remineralization means to re-grow tooth enamel.

2) True or False: The hard layer that fills the tooth, below the enamel coating, is called the cementum.

3) True or False: You should keep your mouth dry while teeth remineralize so the mineral bonds can attach.

4) True or False: Demineralization is rate and only occurs due to extreme wear-and-tear.

Answers are below:

1) False. This process means to strengthen the enamel by putting minerals back into the teeth. It is not possible to re-grow enamel after breakage or erosion.

2) False. It is called dentin. Cementum is another layer which surrounds the roots.

3) False. The opposite is true. Saliva should be flowing in order to supply appropriate amounts of calcium and phosphates for remineralization!

4) False. Demineralization is continually happening as food and drinks create different reactions on the surfaces of the teeth.
