You were looking forward to a brighter smile, but is it normal to have white spots on your teeth after whitening? Well, it’s not normal, but it’s certainly not rare. After a whitening treatment, some people do notice small, white patches on one or more teeth.
People often attribute these spots to the whitening treatment – did it lighten your teeth unevenly? Did it damage your teeth in some way? Rest assured that this is not the case! The cause of white spots after teeth whitening isn’t the treatment itself. Instead, it’s likely that you already had white spots on your teeth, and the whitening treatment simply made the spots more visible.
If the white spots were already on your teeth, though, what did cause them? The most common explanation for white spots on teeth is hypocalcification, or the loss of calcium from the tooth enamel. This might happen for several reasons:
Exposure to too much fluoride as a young child, when your tooth enamel was still developing.
Heavy plaque. This sticky substance contains bacteria that produce acid. As the acids leach away minerals from the tooth enamel, they leave behind chalky, white patches. These white spot lesions, as they’re known, can eventually turn into cavities. Poor oral hygiene and a diet high in sugary or acidic foods and drinks are the main causes of plaque.
Braces or orthodontic appliances. Braces consist of attachments that are bonded to the teeth and then joined together with wires. It can be hard to clean the areas around these attachments, and plaque can build up and leach the minerals from the enamel beneath. When you take the braces off, you may be left with white spots underneath as a result.
Whatever the cause of your white spots, whitening treatment can make them appear lighter and more visible. Even though removing white spots proves challenging, treatment options exist in addition to recommended oral hygiene and care.
