Thankfully, in many cases, we are given a warning sign before something goes wrong. For example, cars have warning lights to indicate you are low on gas or that there may be a problem with your vehicle, allowing you to get your car checked before it breaks down and leaves you stranded. Your mouth works in much the same way. There are often warning signs that you have a problem in your mouth and it needs to be evaluated and repaired. The longer you ignore the warnings, the greater chance you will experience a dental emergency. Read on to learn warning signs in your mouth that you should never ignore.
