A new technique may soon make dentists able to offer patients a drill-free alternative to a traditional root canal.
“Bonded direct pulp capping” is an alternative for patients whose tooth nerve is still alive after decay removal. The dentist covers the nerve with a plastic substance similar to contact lens material, which forms an airtight seal, creating a “direct pulp cap.”
The procedure could eliminate the need for a root canal, while also eliminating the need for follow-up procedures.
