Why Having Whitened teeth doesn't mean they are healthy?

In countries like the US, tooth whitening is among the most commonly asked dental procedures, although the British are often the butt of jokes concerning yellowing gnashers.  Rows of perfect teeth beam from cinema screens and publications. 

It is hardly surprising then that we tend to suppose that whitened teeth are not only attractive but healthful.  Our teeth' hue depends on their inherent color, influenced in part by our age and our bodies, combined with spots from smoking, drinking, drinking and taking certain medications.  Since the enamel begins to eliminate exposing the dentine beneath as you get old your teeth frequently become yellower.

Stains then overlay the yellowing teeth, with foods such as tomato-based sauces and java leaving behind colored compounds known as chromogens, while bacteria or fungi can cause green, greyish, pet appearing stains.

Lots of the experiments on tooth color have been run in laboratory test tubes, instead of in the mouths of alive individuals.  Often cows' teeth have been used because they provide a larger surface area to research to researchers but occasionally extracted human teeth have been tested too.

Surprisingly, black tea does not irritate the teeth unless preceded by white wine

One study conducted by Mark Wolff in New York University saturated cows' teeth for an hour in black tea, red wine or white wine in various configurations.  It wasn't any surprise that the stains were left by the crimson wine.  Astonishingly, the teeth weren't stained by the green tea unless white wine had preceded it.  It appears the wine's acid content made the slightly more porous.

These food and drink-based stains can discolor teeth, but they don't indicate the teeth are unhealthy.  You can have white teeth and still have gum infections or cavities.  You can have healthy teeth that are brownish, yellowish or off-white. 

There's even 1 kind of stain that some researchers consider may protect against tooth decay.  This is the edge you see alongside teeth at the gum line's margins.  It may seem like a run of dots.  It's known as "black stain".

While the reason behind black stain has debated for over a century, the most recent thinking is the fact that it is a special type of dental plaque comprising calcium, phosphate, various bacteria and some kind of iron or copper compound that gives rise to the black color.

Curiously, several studies -- though not all -- have found that kids with black spots are not as likely to get tooth decay.  It's thought that microbes in the blot might be protective.

Just as white teeth aren't necessarily healthy, off-color teeth aren't necessarily bad either

Sometimes, the discoloration can signal decay or another disease, so it is worth getting stains checked from a dentist near me.  But just as teeth that are whitened are healthy, off-color teeth are bad.

Thus, what if you still want glistening white teeth, whatever they express about your wellbeing?  There is a whole selection of whitening interventions from strips, toothpaste, gels, and trays to wear round your teeth.  Most contain abrasive chemicals that rub off stains or bleaching or some combination of both.   Some contain a substance that adds a blueish tinge to the teeth to counteract any yellowness, resulting.

Professionals tend to supply remedies that use more powerful bleaching agents than you can find in-home treatments.  But reviews of the variety of remedies reveal that efficiency varies greatly.  Bleaching can also cause temporary sensitivity in some people's teeth or gums.

And needless to say, if you don't continue with treatment, the whiteness will only last for so long as you prevent the foods and drinks that cause the spots in the first location.

But you know that even without that Hollywood white grin, it doesn't indicate you don't have healthy teeth.
