Plaque and Calculus
Plaque is an invisible film of bacteria which forms constantly on the teeth and gums. When you eat or drink something, the plaque turns the sugar into acid which causes tooth decay unless removed. Plaque will also cause gum inflammation if it is not regularly and thoroughly removed.
The hard tartar or calculus which builds up on the teeth also started off as plaque.
Diet
Food and drinks containing sugar cause decay. Having sweet things less often will help a lot. Foods such as cheese, fruit, nuts and vegetables make good substitutes.
Fluoride
Fluoride helps teeth resist decay so it is important to brush your teeth twice a day with a fluoride toothpaste. If your dentist or hygienist thinks added fluoride would be useful, they may recommend a fluoride gel. They may also suggest fluoride rinses, tablets or drops as an extra help against decay for use at home. Only use these if you have been advised to and follow their instructions carefully.
