How can a dentist be precise? Precision starts with being able to see small details very well. Dr. Geisler, a family Dentist in Plymouth, MINNESOTA, knows what teeth look like when normal glasses are worn and what they look like when magnified 3.5 times. Oftentimes, cracks, decay or other problems are never found if magnification is not used during an exam. Dr. Geisler uses loupes and lighting to allow her to see everything in your mouth. She can check her fillings and crowns to make sure they will last a long time. It is so important to use magnification, that Dr. Geisler has all her clinical staff using magnification.
