What to do while you wait for your Ontario appointment
- Pain relief: ibuprofen and acetaminophen taken together, as the labels allow, usually work better than either alone. Avoid heat on the face.
- Bleeding: bite on clean gauze or a damp tea bag for 20 minutes without checking. If it soaks through repeatedly, tell the operator when you call.
- Lost filling or crown: keep the crown if you have it. Temporary dental cement from a pharmacy can cover the tooth until your appointment.
- Tooth knocked out: do not scrub the root. Put the tooth in milk or hold it in your cheek and get to the dentist within the hour if you can.
