Q. What is the difference between an avulsed tooth and a chipped tooth?
A. An avulsed or knocked-out tooth is totally removed from its socket, root and all. A chipped tooth is a broken tooth where some of the tooth remains in the socket while the remainder is broken off.
Q. If I knock out a tooth can I push it back in myself?
A. Yes, an avulsed tooth can be pushed back into its socket immediately. In fact, if done within 30 minutes of avulsion this is the best treatment with the highest rate of success. The success rate will be significantly higher if the tooth is soaked in the Save-A-Tooth system for one minute prior to reimplantation.
However, immediate re-implantation is often not possible for a variety of reasons:
-
•The patient can be scared, panicked, or not willing to cooperate.
-
•The patient may suffer from more serious injuries that need immediate medical attention.
-
•The first aid provider at the scene may not have the confidence or the ability to reimplant the tooth.
-
•Given that there is blood involved with this injury, many people are unwilling and/or afraid of diseases.
Q. If I push the tooth back in myself, do I still have to see a dentist?
A. Yes, You should make an appointment for one week after you push the tooth back in to make sure the tooth has not been rejected.
Q. How quickly does a knocked out tooth begin to die?
A. When a tooth is knocked out, the ligament that holds the tooth in its socket (or PDL) is torn in half. The PDL cells that remain on the tooth root begin to die within 15 minutes of avulsion. After 30 minutes, success following re-implantation diminishes rapidly. These PDL cells die quickly because they are cut off from their blood supply.
Q. If a tooth cannot be reimplanted within 30 minutes what is the key to successful reimplantation?
A. If teeth are not stored in a protective medium within 30 minutes, the tooth needs to be either reimplanted immediately or stored in a medium that will revitalize the tooth such as HBSS or Viaspan. Successful reimplantation after 30 minutes goes down to 50% or less without a revitalizing medium
Preserving the vitality of the PDL cells is critical. The tooth must be stored in an environment that is physiologically compatible with the cells. This means having the correct pH, osmolality (fluid pressure), and nutrients. Studies show that when a Save-A-Tooth® kit is used, up to 91% of knocked-out teeth were successfully re-implanted.
Q. Some dentists recommend milk. Why is this incorrect?
A. Milk has never been scientifically or clinically proven on humans to work. Research has shown that milk will keep teeth alive for about an hour before it begins to harm the tooth. Sour milk and powdered milk will also kill teeth. No form of milk will re-grow cells. Having refrigerated milk on hand all the time is costly and ineffective compared with the cost of a tooth saving kit like Save-A-Tooth® . A carton of milk is also an inappropriate container for carrying teeth as there is no way to get the teeth out without damaging the tooth. Thirty years ago, milk was considered an acceptable storage medium but thanks to better technology and research the new gold standard medium for saving teeth is Hanks Balanced Salt Solution or HBSS. To date, Save-A-Tooth® is the only tooth saving kit in the world containing this breakthrough solution.
