Plaque forms when food particles mix with saliva and bacteria that naturally occur in our mouths; it contains bacteria that produce acid in our oral environment, which eats away at the hard outer enamel of our teeth. If left untreated, severe gum infections can lead to tooth loss. To avoid gum disease, you must practice good oral hygiene. Brush and floss regularly to remove plaque that can irritate gums. It's also important for children to see a dentist twice a year to prevent cavities, and this may prevent gum problems from developing in the first place. Be sure to schedule regular dental checkups so your dentist can clean your teeth and perform an exam every six months.
Fluoride treatments administered by your dentist can strengthen tooth enamel and help fight decay, and it may be recommended for people who are prone to cavities. Another cause of tooth decay is malnutrition, or a diet that lacks certain vitamins, minerals and other nutrients needed for healthy teeth. For example, not getting enough vitamin D can lead to dry mouth, which encourages the growth of cavity-causing bacteria; iron deficiency can also increase your risk because it prevents the formation of some proteins needed for structural strength in enamel. This is one more reason why if you're worried about cavities, you need to practice proper dental hygiene.
