No, the dental whitening will not damage your enamel or your gums. it is quite safe. You need to keep in mind that when we do whiten your teeth, it dries it out. This allows the main ingredient to reach your dentin and whiten it. Once that is finished, you will start producing saliva again, which will moisten your teeth. Just be careful to not drink anything that can stain your teeth when you are starting this.The only thing you really have to worry about is some possible early gum or tooth sensitivity that should go away after a short time. If it persists, just think about stopping the bleaching for a bit.
