What Causes White Spots to Form on the Teeth?
The exact cause of a white spot can vary. For example, some are a side effect of plaque calcifying in place and causing a cavity that needs to be filled. In other cases, the discoloration is a result of demineralization and remineralization; small amounts of the tooth’s structure can be lost due to acids and poor oral hygiene, and this gives lesions of calcium deposits a chance to form underneath the enamel’s surface. People who wear traditional braces tend to be at a higher-than-average risk for white spots since it’s much easier for plaque to build up around the brackets. In some cases, excessive exposure to fluoride can cause white spots to form; for that reason, it’s important to always remember to spit out your fluoride-based toothpaste instead of swallowing it when you’re done.
