Are bad teeth genetic?

Is this all actually about DNA? Does good hygiene not have anything to do with your teeth? Well, it has been found that genetics plays a major role in the health of your gums and teeth. Your family medical history can tell you if you will have crooked teeth, strong teeth, small teeth or big teeth or are more susceptible to cavities and gum diseases. Despite having a chance to blame your bad teeth on your family, the genetic influence can still be controlled and managed to an extent by being in the driver’s seat of your oral and dental health.
