Dental crowns are like protective caps for your teeth. They're used when a tooth is weak, broken, or has a big filling. Crowns are also great for improving the look of your teeth, like covering up discoloration. As for how long they last, it's kind of like how long a pair of good shoes lasts – it depends on how well you take care of them. On average, they can last anywhere from 5 to 15 years, but with really good care, they can last even longer. Regular brushing, flossing, and dentist visits are key
