With the growing popularity of teeth bleaching products on the market, more people are beginning to wonder if teeth bleaching is right for them. Questions are also arising about the safety of teeth bleaching,
Almost every teeth whitening product you can find uses the same kind of ingredient called carbamide peroxide. The difference is that companies will offer different strengths of the peroxide, and having too much could cause problems. Most people will want to make sure they stick with 10 % carbamide peroxide, especially if they have a tendency to tooth sensitivity.
The biggest problem you will face in the teeth bleaching process is that extra sensitivity to hot and cold liquids. And you might even feel some pain when you breathe in some cold air if you have used too much peroxide. The reason your teeth get sensitive in the bleaching process is that the chemicals make your teeth a little more porous, and these tiny holes allow air and liquids to have access to your nerves.
You can increase 4-5 shades of brightness based on how much whitener you use and for how long you use it. Using trays and peroxide, it can take up to 2 weeks to see four shades of whitening.
