Teeth whitening is a popular procedure done to brighten your smile. First, speak with your dentist to see if whitening is a good option for you. Teeth have to be free of caries before whitening them. Depending on the type of discoloration that is present on your teeth, whitening may or may not be effective. Common reasons for teeth discoloration result from using tobacco, staining from food or drinks, and poor oral hygiene. Tooth whitening is most effective on surface yellow stains. Although whitening is helpful for the appearance of teeth, it is not permanent, and stains may recur over time. There are many types of whitening that can be done and the most common type is a gel-solution that can be applied directly to the surface of the teeth. This type of whitening can be done at our dental office or at home. Whitening at the office usually uses a higher concentration of whitening agent to give you a quicker result. Patients usually notice a lighter shade within an hour. At M&M Smiles, you and your dentist will decide whether an office or at home whitening procedure is better for you.
