Taking care of teeth the London way

2. The COMPUDENT WAND is now becoming really famous as the computerized injection for dental anxiety patients.

All the dentist has to do is hold and point and the computer dies the rest. Neat, right? The best part is as the needle is almost invisible; very few patients get anxious before the procedure. The computer decides the rate of flow and pressure of the local anesthetic solution and this considerably reduces the pain from the injection.
