First Aid Management of Knocked Out Tooth

What Should You First Do For Knocked Out Teeth

Knocked out tooth is one which is completely displaced from its socket, in medical terms this is referred to as ‘Tooth avulsion’. Whether you are looking after children in a school or playground, playing contact sports yourself or are involved in some kind of accident, one of the most common problems that you can encounter is the tooth getting knocked out of its socket.

Avulsion or knocking out of permanent teeth is the most serious of all dental injuries. According to research published in 2007 by Flores MT et al, avulsion is reported to be seen in 3% to 16% of all dental injuries.[1][2]  It occurs most frequently between the ages of 7 to 14 years, usually affecting the maxillary central incisors (upper front teeth).[3]


An avulsed permanent tooth is one of the few real emergency situations in dentistry. And once such an accident occurs the first steps taken and time period become vital in deciding whether the natural tooth will be saved or not. Therefore it is imperative that public awareness is created about first aid care for a knocked out tooth. Healthcare professionals, parents and teachers should receive information on how to proceed following these severe unexpected injuries



Before we talk about the first aid steps following a tooth getting removed from its socket, it is important to know the factors that will determine the success of management that you provide. Our primary goal here is to replace the knocked out tooth back in its place and also preserve the supporting tooth structure. Critical factors that we need to keep in mind are theamount of time the tooth spends out of its socket, the storage medium we use while transporting the tooth to dental office and the general health of the patient.[4][5]


Another very important factor to be kept in mind is the maturity of the tooth root and whether the tooth knocked out is a permanent tooth or deciduous tooth (milk tooth).[6]Always remember that you should NEVER try to reinsert a milk tooth back in its place. Because by doing so there is a chance that u may damage the permanent tooth that is growing underneath and be ready to come out. In such a situation, contact your dentist and take the child to see him immediately.
