The teeth whitening kits that you can buy in stores are notorious for causing chemical burns and the loss of tooth enamel. Because these kits are made to be one size fits all they often don't fit right. When the tray or the strip doesn't fit your teeth exactly right there is a bigger risk that you will get some of the toxic tooth whitening solution on your gums which will cause burns. And the more you use these DIY kits the more damage will be done. Over time these kits strip the enamel from the teeth which can weaken the tooth and cause discoloration or even tooth loss.
Professional Whitening Treatments
Professional whitening treatments aren't much safer than DIY kits. If the dentist performing the treatment hasn't had enough training using a laser during light-accelerated whitening the laser could damage your teeth. If the gel or other whitening agents aren't put on carefully or if the safety shield for your gums slips or isn't applied correctly you could end up with serious chemical burns on your gums. Everyone makes mistakes, so even experienced dentists can cause injuries when performing teeth whitening procedures. It's safer to choose a natural tooth whitener that won't cause chemical burns, tooth loss or other problems when you want to whiten your teeth.
