Although tooth enamel is strong, it’s still susceptible to certain things that can permanently damage your smile. Here are a few examples:
Wear (Bruxism): When teeth wear against other teeth abnormally — whether it’s due to a misaligned bite or a clenching and grinding habit like bruxism — your enamel will suffer. Gradually, the teeth will develop jagged or sharp edges, before getting flatter over time.
Adjusting how healthy teeth bite together can help to eliminate unwanted wear.
Aggressive Toothbrushing: Always use a soft bristled toothbrush when you clean your teeth, and only place just enough pressure to make the tissues blanch. Anything more than that — or using moderate to stiff bristled brushes — can physically wear notches into your enamel.
Such areas are usually seen along the corners of your mouth, close to the gumlines. That is, just behind your eye teeth and in front of your molars. A triangle-shaped notch appears cut into the tooth and gum recession may also be present.
Acids, Plaque, Sugar, and Carbs: As you probably guessed, enamel is also susceptible to elements that cause cavities. A cavity is a physical “hole” inside of the tooth, due to bacteria and acids eating their way through the enamel.
Acidic liquids (such as diet soda or sports drinks) or a high-carb diet can encourage a higher amount of plaque biofilm inside of your mouth. Without proper brushing and flossing, those bacteria will multiply and create new acids, continuing the decay process and causing the cavity to spread. As we learned already, once a cavity works its way through the enamel, it expands more quickly inside the inner layers of the tooth.
