Hi, if the tooth is discoloured, there may have been a trauma to the tooth resulting in pulp necrosis
or pulp death. The surrounding gums may also be bleeding due to the same reason. The trauma may be mechanical, chemical, exposure to high temperature due to consumption of very hot foods. All these result in pulp and gum trauma. Please apply Mucopain ointment on the gums and consult a dentist
to know about the treatment plan for the tooth. You may need root canal treatment
with a crown for the tooth. Take care!
