We’ll end our discussion of Fluoride with a brief list as to when it is recommended. Here we go:
1. Patients who are in a moderate to high risk group of developing decay. This includes those undergoing radiation therapy to the head and neck and also individuals taking certain medication. These can cause a decrease in salivary flow which results in a condition called dry mouth. Saliva acts to wash away plaque and food debris: If not present, these substances will adhere to the tooth’s surface and cause decay.
2. Orthodontic Treatment: Due to the brackets, braces, wires, elastics and other paraphernalia that are involved, it is harder to keep your teeth clean. This usually translates into an accumulation of plaque and food debris and ultimately an increase in the risk of decay.
3. For children that don’t live in areas where the water is fluoridated.
4. People who have sensitive teeth. Fluoride varnish helps to decrease sensitivity that is caused by exposed nerve endings on root surfaces of the teeth (please see the last blog posted on February 25, 2013.)
Exposed root surfaces are dentinal surfaces that are no longer covered up by the gums.
These discolored areas are considered to be weaker than normal tooth structure.
They are not the same as the ones discussed in part one (fluorosis). These are referred to as areas of Hypomineralization; areas that didn’t get enough minerals when they were forming.
In the next blog we will look at what Hypomineralization is.
In order to deal with the above issues, we rely on fluoride in the form of mouth rinses, gels and foams that are placed into special trays and then inserted into the mouth (please see image from the previous blog).
A common regimen of fluoride treatment is to place the trays in your mouth for four minutes per day once daily…Oh and no eating or drinking for 30 minutes after.
