Do you feel like your teeth are going numb when you drink cold water or eat a piece of ice cream? Or are you afraid of tooth decay? A special medicine that doctors recommend to help with things like this is called Stannous Fluoride. This usually comes in the form of a mouth rinse. Today, we will talk about this in detail, very simply.
What is Stannous Fluoride?
Simply put, it's like a shield that protects your teeth. Stannous fluoride is a type of mineral called fluoride. This fluoride is very important for the health of our teeth and bones.
This medicine does two main things:
1. Prevents tooth decay: This strengthens your teeth. That is, it strengthens the outermost layer of the tooth, the part we call enamel, and reduces the damage caused by bacteria.
2. Reduces tooth sensitivity: Some people have extremely sensitive teeth. This means that their teeth become numb when they eat or drink hot or cold things. This medicine helps reduce that sensitivity.
Things to tell your doctor before use
Before your doctor prescribes this medicine, he or she will need to have a complete understanding of your health condition. Therefore, if you have any of the conditions listed below, be sure to tell your doctor.
- If you have artificial teeth made of porcelain or ceramic .
- If you have an allergic reaction to this stannous fluoride, any other medicine, food, or food dyes.
- If you are pregnant, trying to get pregnant, or breastfeeding.
By telling you these things in advance, it will be easier for the doctor to decide whether this medication is right for you or not, or whether you should go for another option.
