If you are overly concerned about the formation of cavities, then you should invest in preventative dental care services. Fluoride treatment may be of benefit to you, especially if the following situations apply to you.
You Use Well Water
Fluoride is naturally occurring in groundwater, and this includes the water that you get from your well and spring. However, the fluoride content may not be enough to encourage good remineralization. So, you do want to have your water tested to see if the fluoride is 2.0 mg/L, as this is the recommended level for water that is consumed.
If the fluoride is below the 2.0 mg/L level, then you should speak with your dentist about a fluoride treatment completed once every three, six, or twelve months. This depends on the fluoride level of the water and also the condition of your teeth. For example, if you are predisposed to the formation of cavities, then you may need treatments more often.
In addition to in-office treatments, you should be investing in fluoride products to use on your own. Fluoride-containing toothpastes and rinses are a good choice, and you may even need to take an oral supplement. Keep in mind that supplements are typically only required if you are drinking water that has very little to no fluoride.
You Have Sensitive Teeth
Some people have enamel that is relatively thin and soft. If you have teeth like this, then you likely inherited the trait from one or both of your parents. When the enamel is thin thin, it reveals the dentin tooth layer that is extremely sensitive to pressure and temperature changes in the mouth.
Soft enamel is far more susceptible to erosion than hard and thick enamel. To help the teeth sustain acidic and bacterial attacks, you want to encourage remineralization where minerals are added to the enamel. This is possible with the application of fluoride.
Fluoride treatments are often given at regular intervals around once every year or so if your enamel is not strong. Your dentist may also suggest the use of a low-abrasive toothpaste so that the soft enamel is not worn away. This can help with the retention of minerals once they strengthen the enamel.
As you speak to your dentist about fluoride for preventative purposes, keep in mind that too much fluoride can cause an issue called fluorosis where white spots form on the teeth. You want just enough fluoride to strengthen the enamel without consuming so much that fluorosis develops.
