If my tooth was hit hard and i tasted a little blood, but the tooth is still in the same position and is still attached, should i be concerned?

Time will: tell.....See your dentist ASAP...the tooth should be PROTECTED from further trauma!! There are materials used to do this...this is something you should NOT wait for if you want to save the tooth! Dr Z

Certainly: Trauma to a tooth does not always result in an immediate issue. The impact often pushes the tooth into the socket, crushing delicate blood vessels and eventual death of the tooth nerve, resulting in the need for root canal therapy. This can occur days, months, or even years after the impact. Let your dentist take a look and with a radiograph, a baseline can be established.
