If you experience discomfort in a tooth or any part of your mouth, visit your dentist as soon as possible. Do not ignore it until the pain worsens or becomes unbearable.
In case of severe pain or swelling, consult your dentist before taking any medication.
If a tooth gets knocked out due to an injury, rinse it gently with saline solution or milk, and keep it stored in saline solution or milk until you seek professional care.
