The sealant forms a smooth, protective barrier, by covering all the little grooves and dips in the surface of the tooth. Much dental decay starts in these grooves.

The rest are usually sealed as soon as they appear which can be any time between 11 and 14 years of age.

It may be available on the NHS and is not a costly treatment, but in many cases it is available only privately. The cost varies from dentist to dentist, but it is usually good value. Good oral hygiene is still an absolute necessity. The smooth, sealed surface is now much easier to keep clean and healthy with normal toothbrushing. Use of fluoride toothpaste will also help to protect your children's teeth.
