It is always better to prevent a problem from happening than to solve it later. Preventive dentistry focuses on maintaining healthy teeth and gums so that any dental issues can be prevented. Getting a dental sealant is one such activity. This prevents build up of plaque on vulnerable teeth surfaces, preventing tooth decay.
Dental sealant is a thin coating, made of plastic, painted on the teeth that are used for chewing in order to protect them from decay. These are usually the teeth at the back – the premolars and molars. Bonding occurs between the sealant and the grooves and depressions on the teeth surface, acting as a shield over each tooth and preventing decay. Even though the food particles and plaque are removed regularly through brushing and flossing, some areas are hard to reach and clean, allowing accumulation of plaque. Sealants cover such areas of the back teeth and keep plaque from accumulating, thereby preventing decay.
