A brighter smile can be a fun confidence boost, especially when you have a special event coming up or simply want to freshen up your appearance. With so many teeth whitening products available at stores and online, it can be tempting to keep whitening your teeth whenever you notice them starting to look a little dull. But can you have too much of a good thing?

The answer is yes. Using teeth whitening products more frequently than recommended can increase your risk of side effects, particularly when you’re using products without professional guidance.
