How long does the sealants last?

Sealants usually last for 3 to 5 years, but your dentist will want to check them regularly to make sure that the seal is still intact. A dental sealant only provides protection when it is fully intact so if your sealants come off, they have to be resealed.

Using a fluoride toothpaste will also help to protect your teeth. Children up to three years old should use a toothpaste with a fluoride level of at least 1000ppm (parts per million). Three-year-olds to adults should use a toothpaste that contains 1350ppm to 1500ppm of fluoride. Pit and fissure sealing reduces tooth decay and the number of fillings you might need.
