Bleaching includes several different methods. Dentists can treat both vital and non-vital teeth. The in-office bleaching is the safest way to whiten your teeth. It is always supervised by a professional who knows exactly what they’re doing. They use whitening bleaching agents that contain either hydrogen peroxide or carbamide peroxide. These two agents have the ability to release an oxidizing agent that enters inside the tooth enamel and releases the discolorations. The dentist will first determine whether the patient is eligible to undergo this cosmetic treatment, and then start with the procedure. There are several different procedures and ways to activate the bleaching agent. First, he applies a special material, that will protect the gums. Then he applies the agent which can be either hydrogen peroxide or carbamide peroxide. These days, light-accelerated bleaching is very popular. That is when the dentist uses a LED or halogen light to activate the whitening agent and accelerate the process. Non-vital teeth have to be whitened with internal bleaching, which includes placing the agent inside the tooth.

The home bleaching process includes whitening pastes, strips, gels, mouthguards or any over-the-counter agent used at home. Some of them can be prescribed by dentists, while others you can simply buy in the pharmacy or the nearest store. Some of these methods can be a little dangerous, especially if they are not used properly. That is why it’s better to get professional help.
