could this spell the end of painful fillings? scientists develop a new method to repair small holes without the need to use a drill - perforated plastic sheet
Free alternatives to the painful fillings may be available soon.
Scientists have developed a new treatment that can fill small holes between teeth without a drill bit.
Usually, the patient's mouth is numb, and then the dentist will drill the tooth structure to enter the mouth.
This new therapy, known as resin penetration, involves a dentist sliding a perforated sheet between the teeth and the cavity.
Drilling is not required, and surgery that is tried out at the University of Alabama in Birmingham is usually done without anesthesia.
Dr. Augusto Robles, from the College of Dentists at the University, said: "When we form tooth decay between teeth, sometimes we have to go through the teeth and eventually we break the healthy tooth structure.
"This new system allows us to skip drilling and help us maintain this structure.
"I never thought it was possible for dentistry.
In my 24 years of practice, this has changed everything we have done so far.
Resin penetration involves cleaning the cavity by passing the gel through the perforated sheet.
Then fill the teeth by passing the liquid resin through the perforated sheet.
Finally, the dental curing lamp is applied to the teeth to solidify the resin.
This potential painless treatment is expected to be recognized by patients.
DrNathaniel Lawson, also from the University, added: "Because this is a No. shot and no-
Drilling treatment is very popular with patients.
This is a very conservative operation due to no tooth extraction.
However, while this new treatment may cause pain --
For some not all patients, the free solution will be able to benefit from the walkthrough
Resin penetration is possible only between teeth or on a smooth surface with a small cavity.
The large or cavity located at the top of the teeth is not suitable for this treatment because the liquid resin used cannot form a shape.
Dr. Robles said: "The resin must be liquid in order to be absorbed into the cavity between the teeth.
So the application is very specific at this point.
Resin penetration is already FDA-
It has been approved in Germany.
A few months ago, scientists invented fillers that help the teeth to repair themselves.
