Infection control is such an important issue that dentists are required to take a continuing education course on the subject every four years. When you come to our office, you will immediately notice that everything - chairs, handles, switches, surfaces - is covered in plastic. Coverage is considered superior to trying to disinfect surfaces with toxic chemicals. Disposable items are used wherever possible and everything else is sterilized. The idea is that nothing that touched the previous patient touches you. This is called "breaking the chain" and we are very serious about it.
