Dark spots on toddler's teeth

My son is 18 months old. About 2 months ago, he had a bad case of the stomach flu. He was constantly vomiting and I tried to keep his mouth clean but sometimes he fell asleep. So soon after this I started noticing some dark spots on his teeth, I don't know why I disregarded this but now the spots are bigger and look pretty bad. Are these spots cavities?


It's possible his teeth have started decaying. Vomitus is partially composed of acidic gastric juice from the stomach. This acid can erode the structure of the tooth surface. The outer layer (i.e. enamel) of primary teeth is much thinner than permanent tooth enamel. Once the second layer (i.e. dentin) is exposed, it is much easier for decay to form and spread. Take your son to the dentist for an examination.

Continue to do what you can to keep your son's teeth as healthy as possible. This goal includes good homecare, including brushing at least twice a day and flossing once a day. Also, if he needs a bottle at bedtime, give him only water. Limit the amount of sugar intake. While these steps won't eliminate the decay he might already have, they could help slow down the spread and prevent new decay from starting.
