When people hear that they have a cavity, they are often surprised because it doesn't hurt. The truth is that early cavities do not always cause pain.
What Is Tooth Decay?
Tooth decay begins by entering the tooth at the outermost layer – the enamel. Since the enamel is the strongest, thickest layer of the tooth, and does not contain any nerve endings many patients will not feel any pain when the cavity is in this early phase. Once the decay penetrates the enamel, it continues to spread and pass through the other layers of the teeth. In most cases once the patient starts to have hot or cold sensitivity or pain, the decay has already spread much deeper.
You do not want to wait until you feel pain to have your cavity treated. Waiting too long can often cause for the need for more extensive and costly treatment such as a root canal, crown, or even an extraction. Read more about our Tooth Colored Fillings here.
