The quick answer is no, your dentist cannot tell your parents if you vape. However, there are some telltale signs that may give them cause for concern.
For starters, if you vape, you're likely to have nicotine stains on your teeth. These yellowish-brown stains are difficult to remove and are a dead giveaway that you use tobacco products.
Additionally, people who vape are also more likely to have gum disease. This is because the nicotine in vaping products can decrease blood flow to the gums, making them more susceptible to infection.
If your dentist notices any of these signs, they may ask you about your tobacco use. It's important to be honest with your dentist so they can provide you with the best possible care.
So, while your dentist cannot tell your parents if you vape, there are some ways they can figure it out. If you're worried about your parents finding out, the best thing you can do is to stop vaping.
