My son is 2 years old and I’m a single parent. His mom died in an accident last month. Taking care of a 2-year-old is a big responsibility. My wife used to take care of these things. Yesterday, when I brushed his teeth, I saw some black dots at the tip of his front row teeth. He gets a lot of pleasure while thumb sucking. Can this habit be a root cause for his dental issue? I am worried about his dental health. I am planning to take him to a dental hygienist in High park ( http://www.bloorwestdentistry.ca/hygiene-care.php ). Is he too young for this treatment? Which is the recommended age for a dental hygiene treatment? Or where can I find a kids dental hygienist? Do you have any suggestions?
