What treatment can you have at the dentist to protect your teeth ?

As each of the adult molars (back teeth) appears, and if the tooth is free from decay, a ‘pit and fissure sealant' can be used to protect the tooth. The sealant is a plastic coating that fills all the little crevices in the tooth surface, creating a flat surface that is easier to clean. Adults can also have this treatment if the teeth are free from decay. Your dental team will discuss whether this is right for you. Children can also have fluoride varnishes painted onto their teeth twice a year which will help to reduce the chances of decay.

Explanation:

The basic cycle of energy shows how energy decreases as it moves through higher trophic levels in an ecosystem. In the first level, the primary organisms (such as plants) utilize energy from the sun to generate biomass through photosynthesis. In the second level, the organisms exploit primary trophic level organisms as food sources and thus obtain energy. Finally, in the third level, carnivores eat the herbivory organisms to obtain energy. At each trophic level, an important part of the energy is lost as metabolic heat; however, this energy can not be reused, this principle is known as the 'law of conservation of energy'.
