Thermoseal Repair is a medicated toothpaste from ICPA for sensitive teeth and everyday acid wear. It contains strontium chloride hexahydrate 10% w/w. When enamel thins, tiny tubes in the dentine stay open, and cold, sweet, or touch sets off a sharp zing. Strontium ions settle in those tubes and slow the fluid shift that triggers the nerve. The paste is mint-flavoured and foams like a normal toothpaste. It is an OTC product, not a prescription medicine. Use it regularly. One night of brushing will not close the problem.

How Does It Work?
Strontium ions from the paste enter open dentinal tubules. Less fluid moves inside those tubes, so the nerve gets fewer sharp signals from cold, sweet food or a toothbrush. ICPA also describes a strontium-calcium layer that stands up better to acid, which is why the paste is used when fizzy drinks and acids have worn the surface. It is not a filling, and it does not rebuild a broken tooth.
Directions For Use
Use a pea-sized amount on a soft brush.
Brush gently for two minutes, especially along the gumline where sensitivity is felt.
Spit out. Do not swallow.
ICPA suggests it as a night toothpaste. You can keep a fluoride toothpaste at another time of day if your dentist wants both.
Use it every day. Sensitivity relief builds with regular use.
See a dentist if pain stays, or if a tooth hurts when you bite.

FAQs
Q1. What is Thermoseal Repair toothpaste used for?
Ans. It is for sensitive teeth and surface wear from acids. Strontium chloride 10% helps block the tiny tubes that carry sharp pain to the nerve.
Q2. Is this a prescription toothpaste?
Ans. No. Thermoseal Repair is an OTC medicated toothpaste. You can buy it without a prescription. A dentist should still check pain that does not settle.
Q3. Can I use it with my fluoride toothpaste?
Ans. Yes. ICPA suggests using Repair at night, and you can keep a fluoride toothpaste for another brushing if your dentist wants decay protection as well.
Q4. How soon will the zing from cold drinks stop?
Ans. Some people notice less sensitivity after regular brushing. It is not a one-time fix. Keep using it daily, and see a dentist if a tooth still hurts.
Q5. Does it repair a chipped or decayed tooth?
Ans. No. It only helps with sensitivity and acid wear on the surface. A chip, hole, or pain on biting needs a dentist, not more toothpaste.
Q6. How should the tube be stored?
Ans. Close the cap and keep the tube in a cool, dry place, away from heat and sunlight. Store it out of children’s reach, so it is not swallowed.
