Your mother was right: Never open bottles, packages, or other containers with your teeth. You might permanently chip or crack the enamel.
Gnawing on anything else -- like pens or fingernails -- or chomping down on seeds, popcorn kernels, or ice could have the same result. Above article from: Webmd.com/oral-health
Although tea has a reputation as a healthy beverage, it may not be the best choice when it comes to keeping your teeth white. Dentists say tea -- especially the basic black variety -- can cause more stains than coffee. However, recent studies have found that even herbal teas and white teas have the potential to erode enamel and cause tooth staining.
Enamel is kind of like the shell of an egg: it protects the softer, more vulnerable part of the tooth inside.
But unlike an eggshell, the thin layer of enamel is tough. In fact, enamel is the hardest substance in the body. It can withstand decades of biting, chewing and crunching -- with some luck and good dental care. Above article from: WebMD.com/oral-health
Another cause of tooth enamel damage is bruxism -- or teeth-grinding. Over time, the constant clenching and friction can wear down or fracture the enamel. In this slide, teeth grinding has ground down the upper and lower front teeth.
Bruxism is often worst when you sleep -- that's when you can't control it. Reducing stress may help. Some people wear a special mouth guard to bed.
Opening bottle caps or plastic packaging with
your teeth may be convenient, but this is one habit that makes dentists cringe.
Using your teeth as tools can cause them to crack or chip. Instead, keep
scissors and bottle openers handy. Bottom line, your teeth should only be used
for eating.
