Do I need to go see a dentist? Is there something that needs to be done?

It is recommended to consult a dentist if a tooth changes color after receiving a blow. While treatment for primary teeth is usually only necessary if there is pain or infection, sometimes discoloration may prompt a consultation. In such cases, the dentist may be able to hide the discoloration with a filling in a few years. If there are no signs of infection or pain, it is not necessary to see a dentist immediately. Instead, you can bring it up at your next regular dental check-up and cleaning.
