Can You Reverse a Cavity? (5 Simple Steps)

When you think of a cavity, most immediately think about how much it hurts and how much it costs. Fortunately, there are ways to reverse or heal a cavity before it progresses to an irreversible stage. You may be wondering how this is possible? Cavities occur when bacteria form acid, which degrades the tooth surface.

When the cavity begins this process, it attacks the enamel first. During this stage, the enamel surface breaks down; however, there’s no hole in the tooth, yet. If a cavity is discovered during this stage, fluoride application treatments can be administered to reverse the cavity process.

Most cavity risk factors are out of our control because of genetics or anatomical issues; however, you can modify some risk factors to help prevent cavities.

The more frequently sugar bathes the teeth, the more opportunity the bacteria have to use this as their food source and produce cavity-causing acid.

Why Does a Cavity Hurt? (5 Toothache Home Remedies)

Cavities can be a real pain. Each tooth has a delicate nerve in the center that relays helpful information to your brain, such as temperature, pressure, and irritation. Tooth decay occurs when bacteria attack your body (tooth). This irritation elicits a reactionary response, warning your brain that danger is present. Without a pain response, we would cause irreversible harm to our teeth or body.

If this pain response hits you and you cannot get to your dentist, what do you do? The article below that highlights five toothache home remedies that will hold you over until you see your dentist.
