I've been noticing a lot of white patches on my teeth lately. What are they?

Those are called tooth enamel opacities, and they're caused by a variety of factors such as genetics, diet, lifestyle, or certain medications. They can be temporary or permanent, and they can range from small spots to large areas of discoloration. If you notice any changes in the color or shape of your teeth, it's important to see a dentist for an evaluation.
