What if having oral surgery didn't mean having a numb mouth for hours?
That's possible now at McPherson Dental Care with a Solea laser drill, which allows a dentist to perform some kinds of oral surgery without using an anesthetic.
“This is very new to dentistry,” said Brian Kynaston, a dentist at McPherson Dental Care. “There have been lasers since 2003 to cut enamel, but they were very slow.”
The laser drill, acquired in April, can complete a procedure on a single tooth in as little as 5 or 10 minutes. Under a traditional method, a patient would spend that time waiting for the anesthetic to kick in.
The machine uses a hand-held tool to focus a laser at a patient's tooth. The laser can cut through both hard and soft tissue, so it can be used in a variety of procedures. Kynaston estimated his office can perform 85 to 90 percent of all fillings without having to use any kind of anesthetic.
“It saves time for the patient and for us,” he said. “They leave without feeling numb, and I can know immediately if the patient's bite has changed.”
Altering a person's bite means that the filling is differently-shaped than the tooth it replaces. For example, the filling might be taller than the original tooth. Because teeth can sense even miniscule differences, this can cause patients discomfort or pain.
If a person's mouth is numbed, he or she won't be able to tell if their bite has been altered until the anesthesia wears off. With a laser drill, the patient can tell immediately if something doesn't feel right.
This doesn't mean the traditional tooth drills and anesthesia are going away. The laser drill is not as fast as a traditional drill, so if a person wants work on several teeth done at once, the traditional method is faster overall.
However, the new method avoids any problems associated with anesthesia, including allergies, an increased heart rate, and accidental biting of the cheek or lip.
“There's no potential for injury,” Kynaston said. “You can leave the office and go right to lunch if you want.”
Kynaston said the goal is to make dentistry as pleasant as possible.
“Dentistry isn't the most fun thing for everyone,” he said. “With the laser, we're able to fix people's teeth without any shots or numbing.”
