Your dentist will use a whitening solution, with or without a bright light, to improve the shade of your teeth. This method usually involves a strong chemical bleaching agent and will only take an hour in the chair. The results will be immediate and depending on your lifestyle and dietary habits, may last for up to a year.
You may prefer to opt for several treatments to achieve the desired shade of white, but most people will only require one sitting for great results. This is a great solution for patients who would like to whiten their teeth more quickly however, it is also a more invasive process for your teeth than at home.
