Enamel is the hardest substance in the human body, and for good reason—it’s your teeth’s first line of defense against wearing and harmful oral bacteria. But although enamel can “take a licking and keep on ticking,” it can lose its mineral content, soften and eventually erode to expose the teeth to bacteria.

Here are 4 tips for protecting your enamel so it keeps on protecting you.

Practice sound brushing techniques. Brushing is necessary for removing bacterial plaque that can trigger dental disease. But how you brush could prove not only ineffective, but also harmful to your enamel. So, be sure you’re brushing all tooth surfaces, but not too forcefully or too often (twice a day is enough)—otherwise, you could wear down enamel and damage your gums.

Wait to brush after eating. The acid levels in the mouth go up during eating, causing an immediate softening of enamel. But saliva then goes to work neutralizing acid and helping to restore enamel’s mineral content. Since it takes saliva about thirty minutes to an hour to complete this task, wait on brushing at least that long. Otherwise, you might remove tiny traces of temporarily softened enamel.

Avoid eating right before bed. While we sleep, our saliva flow decreases until we wake up. If you eat just before bed, you may not be giving your saliva enough time to neutralize acid before it “goes to sleep” with you for the night. So, give your saliva ample time to neutralize any remaining acid by not eating anymore at least an hour before you turn in.

Limit drinking acidic beverages. Some of our favorite drinks—sodas, energy and sports drinks, and even some juices—can be high in acid. To protect your enamel, reduce your consumption of these types of beverages in favor of water or milk (the calcium in the latter will also benefit your enamel). When you do drink acidic beverages, use a straw to minimize contact of the fluid with your enamel.

Healthy and strong enamel is the key to healthy and strong teeth. It’s worth taking these steps to protect this important defense against destructive tooth decay.
