Why do some People have Yellow Teeth?

There are many factors affecting the color of your teeth. One of the most important factors affecting the color of your teeth is actually your genes. If your mother and father have naturally yellow teeth, then chances are that you will have a similar teeth color.

Causes of Yellow Teeth

Among the primary reasons of yellow teeth (aside from your genes) are food, oral hygiene, and aging. Most of everyday food that we consume contains chromomeric ingredients that are used by manufactures to impart coloring. Food and drinks such as tea, coffee, wine, and certain fruits like berries contain color impurities which stain white teeth. Smokers should also be aware of the fact that tobacco is not only harmful but cause permanent discoloration. Secondly, poor dental hygiene is another major cause of concern. 


Do teeth whiteners damage a tooth's nerve?

There's no evidence to date that the teeth whitening process has a harmful effect on the health of a tooth's nerve. 

Do teeth whiteners damage existing dental restorations?

Over 10 years of clinical use of teeth whitening products containing 10% carbamide peroxide have not shown any damage to existing fillings. The issue is not "damage" to existing restorations; rather, keep in mind that existing restorations such as tooth-colored fillings, crowns, bonding, veneers, and bridges do not lighten. This means that any pre-existing dental work may need to be replaced to match the new tooth shade achieved in the natural teeth, should a bleaching process proceed.

Do teeth whiteners damage tooth enamel?

Studies of teeth whitening products using 10% carbamide peroxide showed little to no effect on the hardness or mineral content of a tooth's enamel surface.

How long do the teeth whitening effects last?

Teeth Whitening is not permanent. People who expose their teeth to foods and beverages that cause staining may see the whiteness start to fade in as little as one month. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed.

Is Gummy smile related to plastic surgery?

This procedure was first described in the plastic surgery literature in 1973 and was recently published in the dental literature. 
"It is important to establish the etiology responsible for the excessive gingival display."


How can a cosmetic dentist fix my gummy smile?

In some cases, if your tooth eruptions are abnormal, and your teeth are small in comparison to your gums, you may seek treatment options from a cosmetic dentist. They can add porcelain dental caps to your visible teeth, which will correct your gum-to-tooth ratio. These caps can also improve the alignment and coloring of your teeth. Crowns, veneers, caps, and invisible braces are just a few examples of ways a cosmetic dentist can improve your smile.

What factors can lead into having a gummy smile?

A Gummy smile can be caused by:

- Having small sized teeth relative to the height of the gum visible, due to genetic factors or excessively worn down teeth.
- Having a short upper lip, otherwise known as high lip line.
- A hyperactive lip elevator muscle.
- Vertical overgrowth of the upper jaw bone, a genetically determined skeletal deformity.
- Teeth which have suffered from altered passive eruption.
- A combination of two or more of the above factors.

What is a gummy smile?

In simple terms, a gummy smile is when one smiles, he or she instead of showing a lot of white dazzling teeth, they show a lot more of the pink gum tissue!

In dental terms, for an aesthetic smile, it’s generally agreed that we should have 1 or 2 mm of gum tissue visible when we smile.  A gummy smile is when more than 2mm of gum tissue is on display when a person smiles.

In most of the cases; as long as the height of the teeth is much more than the pink gum when a person smiles or talks, it is acceptable to people. But, when this ratio changes in favor of more pink gum showing than the white teeth it can become unattractive, resulting in some people trying to improve their gummy smile.
