What You Should Know About Tooth Decay
Active Acids
The outer enamel layer of your teeth is one of the hardest substances in your body, making it a perfect substance to withstand the daily biting pressures required of your teeth over a lifetime. Despite this inherent toughness of design, however, there is common and stealthy enemy that knows precisely how to destroy your enamel: the enemy of tooth decay. Tooth decay is both sneaky and successful because its number one ingredient for success is the presence of your normal oral bacteria. Your body produces a constant supply of these bacteria, which continually produce and deposit plaque on your teeth. This plaque combines with foods and beverages you take in, forming a strong acid that slowly but surely eats away at your enamel. Regardless of your age, tooth decay can get to you if you don't get to these bacteria first.
Aging Adults
While poor brushing habits or sweet snacks may cause young children to struggle with tooth decay, adults must be wary as well, for three main reasons. First, aging can cause gum recession, exposing the tooth root's more sensitive exterior tissue to plaque and acids. This cementum is highly susceptible to decay, as well as to hot, cold, and touch. Second, many older adults grew up without the benefits of fluoride or preventive dental care, and have a significant number of silver amalgam fillings. Over time, these are subject to fractures, leaks and bacteria accumulation, allowing tooth decay to destroy the underlying enamel. Third, older people often have trouble cleaning the edges or margins of their teeth, allowing tooth decay to begin.
The good news is that tooth decay is almost entirely preventable if you're willing to brush properly with fluoride toothpaste after every meal, floss daily, eat nutritiously, and avoid snacks. As you age, you can also take further protective measures such as additional fluoride treatments, dental sealants to cover your chewing surfaces, and more frequent advanced periodontal cleanings.
