In life, we are often given warning signs when something is about to go wrong or cause a problem to disrupt our day. In many cases, these warnings give us ample time to make the changes necessary before something becomes an emergency. For example, a light appears on the car dashboard to warn that gas is getting low or to warn that there is a potential problem with the vehicle. A smoke alarm sounds to give a warning when the battery is about to die or if smoke is detected in the house. Our mouth gives us warnings as well. The longer we ignore the warnings, the greater the chance it will turn into a dental emergency. Read on to learn warning signs in your mouth that you should never ignore.
