If one loses a tooth in an accident, one has to preserve the tooth in milk or saltwater or beneath the tongue. If one can reach an expert dentist within an hour, the tooth can be restored by way of splinting. Root canal treatment has to be done for that tooth. If we restore such lost teeth within one hour, the success rate is 90%. Usually, children between the ages of 7 to 11 loose teeth while playing. So, it is better that children are provided with mouth guards while playing.
