WHAT IS REAL TOOTH EROSION?
A Dentist Explains Everything About Tooth Erosion Does tooth erosion really exist? Or is it just a phrase that advertising companies have cooked up to frighten you into buying particular toothpastes?
Most dentists use the term "teeth erosion" in a completely different way to the toothpaste adverts. Have you seen the television advertisements showing a small light shining through a front tooth, and a voice-over telling you how this proves that you have tooth erosion?
I think that those adverts are NONSENSE!
The tooth they show is actually perfectly normal. If you shine a strong light through anyone's front teeth, you can see the light shining through them! Teeth are translucent. They transmit light, as well as reflect some and absorb some.
SO WHAT IS REAL TOOTH EROSION?Erosion is usually caused by something acidic. It's where a tooth has been worn down, BUT NOT by rubbing on another
tooth (attrition), or by rubbing on something else hard like a really hard
toothbrush (abrasion).
So it's NOT caused by grinding or clenching your teeth at night. And also not by scrubbing your teeth with a hard brush. These things may make the effects of erosion worse, but erosion itself is caused by acids in your mouth.
How do I know if I have tooth erosion?You may notice two things; first, that your teeth seem to be worn down at the biting edges or biting surfaces. This can be caused by grinding your teeth alone, but is more noticeable if you are getting a lot of acids in your mouth too.
