These tips are only temporary measures – in all cases, you should see your own dentist as soon as possible.
Toothaches: First, thoroughly rinse your mouth with warm water. If your mouth is swollen, apply a cold compress to the outside of your mouth or cheek. Never put aspirin or any other painkiller against the gums near the aching tooth, as it may burn the gum tissue.
Chipped or broken teeth: Save any pieces. Rinse the mouth using warm water. If there’s bleeding, apply a piece of gauze to the area and apply gentle pressure until the bleeding stops. Apply a cold compress near the broken/chipped tooth to keep any swelling down and relieve pain.
Knocked-out tooth: Retrieve the tooth and, if possible, try to put it back in place (rinsing it briefly before doing so). Make sure it’s facing the right way. Never force it into the socket. If it’s not possible to reinsert the tooth into the socket, put the tooth in a small container of milk or slightly salty water. Knocked-out teeth have the highest chances of being saved when seen by the dentist and returned to their socket within one hour of being lost.
Lost filling: Stick a piece of sugarless chewing gum into the cavity or use an over-the-counter dental cement.
Lost crown: Make an appointment to see your dentist as soon as possible and take the crown with you. If possible, slip the crown back over the tooth. Before doing so, coat the inner surface with an over-the-counter dental cement, toothpaste, or denture adhesive, to help hold the crown in place.
Abscesses: These are infections that occur around the root of a tooth or in the space between the teeth and gums. Abscesses are a serious condition that can damage tissue and surrounding teeth, with the infection possibly spreading to other parts of the body if left untreated. See your dentist as soon as possible if you discover a pimple-like swelling on your gum that is usually painful. In the meantime, to ease the pain and help draw the pus toward the surface, try rinsing your mouth with a mild saltwater solution several times a day.
