What Bluish Enamel Means
It's common for teeth and gums that come into contact with whitening gel to appear white. But if you notice that the enamel on your teeth has a bluish tint that means that the dentin of your teeth is exposed. Dentin is the bony tissue that lies under the enamel on a tooth. If you are seeing bluish colored tissue on your tooth that means that bleaching has destroyed the enamel on that tooth. Once that enamel has been destroyed there is no way to replace it. Enamel is there to protect the dentin and the pulp of your tooth so if the enamel is gone it means that your tooth is at risk of damage, infection, and you may eventually lose that tooth.
How Bleaching Causes Bluish Enamel
Bleaching the teeth with at home kits makes it easy for people to make mistakes. Leaving the gel on too long or using the whitening kit too often will wear away the enamel on the tooth. Even if you think you are following all the directions correctly there is a good chance that the tray that is supposed to fit over the teeth won't fit correctly because it's not custom made for your mouth. If you are using whitening strips the strips may not be on correctly or you might leave them on too long. A natural whitening solution is a better choice because it will not destroy your enamel but will give you a brighter and whiter smile.
