How to check if you have caries

So, before we go to the hospital to see a dentist, how can we check if our teeth have caries? We can make some simple judgments to know whether we have caries: People with caries will have toothaches. Needless to say, toothaches will feel sore and swollen when eating or drinking, sore and weak when biting, and sensitive to hot, cold, sweet or sour food and drinks; the surface of healthy teeth is white, and the presence of holes, pits, and black spots on the surface of teeth means that there is a problem with the teeth. This problem is divided into large and small. If these black marks are only a small piece, you can ignore them if you can see them with your naked eyes. If they are large and numerous, then they are caries; teeth that already have caries will change their appearance due to stimulation, from beautiful white to white with spots and then to brown or even black areas. At this time, you don’t need to test yourself, and go to the hospital for treatment.
