When growing children suffer an injury to the nerve of growing teeth, a procedure known as revascularisation can be performed instead of traditional root canal treatment. Pulp revascularisation allows for the continued development of the roots of the tooth. A strong root offers a better long term prognosis for the tooth.

If root canal treatment were to be carried out instead of revascularisation, the root growth will be stunted and the root will be prone to root fracture in the long term.

Any growing teeth may be suitable for revascularisation. Common examples are caries exposure in young children, children teeth that suffer traumatic injuries in sports or in a fall, and children who are born with premolars with dens in dente.
