Dr. Owens always says, “By the time your tooth is hurting, it’s too late.” You want to catch dental problems before they become severe enough to cause pain. This is why x-rays are important. This photograph illustrates that.
Visually, the teeth look healthy, but with the x-ray you can see what is technically known as an interproximal cavity (that is, it is located in-between two teeth).
The bacteria that cause cavities is called streptococcus mutans. This bacteria is an anaerobic bacteria, meaning that it cannot live in an oxygen-rich environment. That is they grow best in-between the teeth where oxygen levels are low. In these places, you can adequately cleaned only with dental floss.
