How do you know you have a cavity? Well, sometimes you don't. Some obvious symptoms when you're at home might be sensitivity to colds or when you're chewing and eating. Sensitivity to sweets, especially. Or, you might straight up feel a hole. Other times, you just don't know.
And the best way for me to see that is to take your X-rays, which are called bite wings, which we usually recommend taking on a yearly basis, so that we're able to see in between the teeth to make sure that we're getting the correct diagnosis for you.
