Thermo Best Paste contains Potassium nitrate, Sodium monofluorophosphate and Triclosan in a pleasantly flavoured base. Thermo Best Paste protects against sensitivity, fights cavities and plaque, fights gum problems and strengthens tooth enamel. It is used in sensitivity due to attrition and abrasion (wear and tear of teeth), natural gum recession or post scaling recession and abrasion on the neck of the tooth. All the ingredients in Thermo Best Paste block the nerve that carries the message of pain due to sensitivity to the brain. This protects the tooth and keeps away feeling of pain when eating and drinking. This paste should be used on a regular basis for at least one month to get the maximum benefit. Also massage some of the paste onto the sensitive areas after brushing. Directions of use: Brush twice daily for two minutes with this paste. Don't rinse after brushing for at least 30 minutes as it needs some time to work. By spitting thoroughly instead of rinsing the mouth with water after brushing, the thin coating of paste remains on your teeth and provides the relief it is designed to give. Use under medical supervision.
