Fluoride varnish is used to help with tooth sensitivity and tooth decay prevention, Once applied, the fluoride will last for 2-3 months. It will help decrease tooth decay by 25%.
The varnish, is 5% Sodium Fluoride, takes minutes to apply in the dental office and costs @$50. It appears clear on the teeth and should be kept on the teeth for 6-8 hours. One can eat and drink immediately afterwards. In some cases, dental insurance will cover it. Over-the-counter toothpastes with fluoride have roughly .2% fluoride. In our office, we have personally seen patients, who have had tooth sensitivity decrease or even disappear.
