You probably shouldn't go to the dentist if you have a cold

Going to the dentist if you have a cold is usually not a good idea.  If you are getting over a cold and feel OK to have your check up/polish or treatment then it usually isn’t a problem.  If you felt very unwell and thought your treatment may not be possible then it may be best to rearrange by letting your dentist know as many days before your appointment as possible.  You may be very contagious and you could spread your bacteria to other members of the practice or the staff.  Although dental practices are extremely clean places, germs can still be spread on door handles etc.
