Teeth whitening is one of the most popular procedures performed by cosmetic dentistry today. Teeth can become discoloured for a variety of reasons including diet, smoking, exposure to antibiotics or fluoride and age.
A diet that includes coffee, tea and wine can stain your teeth and consumed over a long enough period that is what they did. Add smoking to your daily habit and the result is teeth that are yellowed or brown from nicotine. If you are looking for the best dentist then you can visit hop over the link.

Teeth can also be discoloured and greyed down due to natural pigmentation or exposure to antibiotics. Early and prolonged exposure to antibiotics such as tetracycline (and related antibiotics minocycline and doxycycline) can penetrate early tooth development and leave discoloration which may be solid, ribbons or patches of colour. Teeth can be discoloured either yellow-brown or blue-grey as a result of exposure to antibiotics.
Even something that is supposed to help prevent cavities such as the use of fluoride can cause tooth discoloration. Children with developing teeth swallowing too much fluoride can develop a condition known as fluorosis that leaves teeth with white spots like chalk or even brown or pitted.
Age can also be a factor in making the teeth look darker. As the age of the enamel surface of teeth wear down and over the underlying tooth and darker looking dentin is exposed.
