Enamel is one of those things we often take for granted. Until it’s gone. And unfortunately, once it’s damaged, it doesn’t grow back. So, how do you know if yours is in trouble?
What Is Tooth Enamel, and Why Does It Matter So Much?
Tooth enamel is the outermost layer of your teeth, and, believe it or not, it’s the hardest substance in your body – even harder than your bones!
Tooth enamel is there to protect the softer, more vulnerable inner layers of teeth, including the dentin, pulp, and nerves, from bacteria, temperature extremes, acid, and daily wear and tear. But even though enamel is incredibly strong, it can be damaged and worn away.
Unlike your bones and other bodily tissues, enamel doesn’t contain living cells, so it can’t heal itself. That’s why paying attention to the early signs of enamel erosion is key.
Signs You Might Have Damaged Tooth Enamel
Unfortunately, enamel is extremely thin and translucent, so it is hard to tell when it is damaged. Here’s what to watch for:
Tooth Sensitivity
This is usually the first red flag when it comes to enamel damage or erosion. When enamel becomes thin, the underlying dentin is more exposed. This layer of your tooth contains tiny tubules that lead to the nerve. As a result, hot, cold, sweet, or acidic foods and drinks might suddenly cause pain and sensitivity.
Changes in Color
As enamel wears away, the naturally yellower dentin underneath becomes more visible. You may notice your teeth appear more yellow or dull than before.
Changes in Shape
As enamel wears away, the shape of your teeth may actually change visually. Depending on where the wear is located, teeth may appear shorter, more rounded, develop gaps, or, in the case of molars, become more pitted.
Increased Cavities
Enamel doesn’t just protect against sensitivity, it also protects your teeth from decay. Weakened or eroded enamel gives bacteria easier access to the inner tooth, increasing your risk of cavities even if your brushing habits haven’t changed.
What Causes Enamel Damage?
Sometimes, the cause is clear, like with a chipped tooth due to injury. Other times, it’s a slow process that happens over time. Here are some of the more common enamel enemies:
- Acidic Foods and Drinks – Citrus fruits, soda, wine, and vinegar-based dressings are all acidic enough to soften enamel.
- Brushing Too Hard – Scrubbing your teeth harder keeps them cleaner, right? Not quite. In fact, vigorous brushing or using a medium or hard-bristled brush can wear enamel down over time.
- Grinding or Clenching – If you wake up with a sore jaw or frequent headaches, you might be grinding your teeth in your sleep, which can erode enamel over time.
- Acid Reflux – Stomach acids that make their way into your mouth (even occasionally) are strong enough to break down enamel.
- Dry Mouth – Saliva helps neutralize acids. If your mouth isn’t producing enough, your enamel may be under attack.
Can Enamel Be Repaired?
Unfortunately, once enamel is gone, your body can’t regenerate it. That’s why prevention is everything. But that doesn’t mean there is nothing you can do. If you catch enamel erosion early, there are steps you and your dentist can take to strengthen and preserve your remaining enamel.
- Use fluoride toothpaste
- Choose a soft-bristled toothbrush
- Avoid brushing immediately after acidic foods or drinks (wait about 30 minutes).
- Talk to your dentist about professional fluoride treatments
- Consider dental bonding
- Treat decay or visible enamel loss with fillings, crowns, or veneers
- Get regular dental visits, as the earliest signs may only be visible to your dentist
