White teeth have a very light shade of yellow and are the healthiest type of teeth. The colour of these teeth comes from a combination of genetics and the amount of time you spend brushing your teeth each day. Slightly yellow teeth have a mild yellow tinge that is barely noticeable.
Healthy teeth are usually off-white or slightly yellowed, and teeth naturally darken over time. But if you notice brown, black, or green stains on your teeth, you may have a chronic condition or need a thorough dental cleaning.
Non-White or Yellow Teeth are Unhealthy
Teeth whitening treatments usually work by stripping or entering the outer enamel layer, which makes teeth weaker if done many times. So, more often than not, yellow teeth are actually stronger than pearly white ones–so long as they're cleaned regularly.

Enamel is on the surface of every tooth and it has a natural hue of white. However, the underlying dentin layer has a slightly yellowish color. This yellowish hue shows through the enamel in almost everyone, but more so for those with naturally thinner or more translucent enamel.
This is because the enamel, the protective layer outside your teeth, is white, but can be thinner for some people and even translucent. The layer directly under the enamel is light yellow. Therefore, it is perfectly natural to have a light yellow color on your teeth, and it is not caused by poor oral health.
Some people are born with whiter, thicker enamel and may simply be blessed with great looking teeth. This is not necessarily an indication of how healthy teeth are: it's just genetics. Beneath the enamel lies the dentin, or the which is usually yellowish.

The strength of your teeth is not related to the color of your teeth. The color of your teeth is determined by the natural color of your dentin, the layer of tissue beneath your tooth enamel. The strength of your teeth is determined by the density of the enamel and the overall health of the tooth structure.
When the enamel is eroded so badly, in its thinnest form your inner layer can be seen, dentin. Dentin has a natural yellow color. So, if your enamel is transparent enough to show your dentin, your teeth look yellow even if you brush them every day.

Healthy teeth are white or slightly off-white in color, with smooth surfaces and well-defined edges. They should also be free of chips, cracks, and visible cavities. The gum tissue surrounding the teeth should be pink and firm, with no signs of inflammation or bleeding.
Teeth that are not perfectly white can still be healthy. The teeth are considered unhealthy if their color is attributed to plaque buildup or staining. Having off-white teeth is often healthy. Myth #3: Braces contribute to yellowing of teeth.
A study has confirmed what we already know – that a white and evenly spaced set of teeth makes people seem more attractive. But it has also explained the reason. It is because teeth are the human equivalent of a peacock's tail – a sign of health and genetic quality designed to help choose a mate.
