Kathy,
I have worked in a dental office, as a dental assistant for 11 years. A sealant is simply a preventive treatment to seal the deep grooves often found in molars,to prevent cavities from occurring. It is a very simple treatment that involves: 1. Cleaning the teeth with toothpaste or pumice (a gritty toothpaste). 2. The dentist or hygenist will then isolate the tooth they are working on by placing a cotton roll (small piece of cotton) beside the cheek and possibly tongue to keep it dry from saliva. 3. An acid etch is applied to the tooth to roughen the surface, so the sealant will stick. ( it tastes bitter if swallowed, but is harmless) 4. Working quickly the dentist then applies the sealant material, usually with a little "paintbrush" 5. Then a bright light called a curing light is applied (we usually tell kids it's a space light) to harden the sealant material. 6. After all sealants are placed the dentist will have your child bite on a blue piece of paper to check to see if the sealant is high ( if your child is biting the sealant before his/her natural teeth ) If the sealant is high the dentist will adjust or polish the sealant. (usually done with a highspeed drill. It only takes a few seconds, and because it is polishing the sealant,not the tooth it does not hurt at all)
So there you have it, that is what is involved in a sealant. There is no need for freezing or needles of any sort. The biggest challenge for kids is that they are often nervous because they do not know what to expect. Ask your dentist to show your child what they are going to do before they start the procedure. If you are nervous or scared do not let your child know, because your child will adopt your fears!!! Stay positive and reassure your child that this is a quick and simple procedure that will help them to keep their teeth healthy and cavity free!!!
