My son has a craving for sweet and salty products. Lately, he has lost his appetite. I am a little worried about his oral health. He has been experiencing toothaches for a while now. We went to a dentist, and he made us aware that he might have cavities because of his eating habits. He recommended that a root canal was necessary as there was a severely bad and damaged tooth infected. This is the first time we visit a dentist as we don't have a family dentist. I am having some concerns if we should go through it or not. Could someone help and advise me on this?
