Dental Sealants are a plastic or synthetic coating placed on your tooth surface which are designed to "prevent dental decay." Are they safe or effective?
The claim is that, "Sealants can provide 100% protection from dental decay or "cavities" on the chewing surface."
If this were true, then everybody could just get a dental sealant and nobody would have cavities. I wish it were that simple. But this idea is simply not accurate.
Steps For Applying a Sealant
- Burn away some tooth with acid
- Paint the liquid sealant on your tooth
- Dry the sealant with UV light
Sealants are said to last 2-4 years.
Where do you think they go when they dissolve and wear out?
The Truth About Dental Sealants
Dental sealants cannot stop tooth decay, but can only treat one of its symptoms temporarily, a hole in the tooth. If, on the crown of the tooth there is some decay, and the nerve is more exposed, then applying a dental sealant only covers up the decay. But it won't ever stop it, because decay primarily happens from within the tooth.
The cause of tooth decay is a deficency of bone building nutrients.
Dental Sealant Safety
As you know, dental sealants are toxic and made with toxic chemicals. There are many varieties of sealants, some less or more toxic than others. Some may have a very low toxicity and not be of harm to humans. But overall, currently used dental sealants are somewhat toxic, and they are likely to have some effect on humans because they contain moderate amounts of a chemical used in the plastic industry called bisphenol A.
Bisphenol A - And Dental Sealants
The plastics industry and the FDA say this chemical is perfectly safe and non-toxic in the amounts we consume. Meanwhile sane scientists are raising the alarm about the effects of even minuscule amounts of this endocrine disrupting substance, on reproduction, fetal development, cancer of the reproductive organs, and other long term health effects.
Endocrine disruptors are a class of substances that bond onto the oestrogen receptors in both men, women and children.
Other dental sealants, promoted as calcium hydroxide sealants, are in fact only about 50% calcium hydroxide. These dental sealants have been linked to Neurocutaneous syndrome (NCS). NCS is characterized by neurological sensations, pain, depleted energy and memory loss as well as itchy cutaneous lesions that may invite various opportunistic infections. NCS is likely caused by two other main ingedients in some dental sealants both known to be toxic; ethyltoluene sulfonamide as well as zinc oxide are considered most toxic.
