Pain free laser treatment could soon be available for patients needing root canal work. American scientists say this could mean an end to the dreaded drill. Scientists say laser treatment will destroy the diseased nerve tissue without damaging the healthy nerve.
They added that the laser treatment also caused less damage to the rest of the teeth. Researchers said vibrations caused by drilling for ordinary fillings could damage the nerve and cause root canal work later in life. If needed, antibiotic paste can be inserted into the tooth through a hole made by a more powerful laser and then the tooth can be sealed.
