Yellow stains on teeth.
Yellow teeth are a common characteristic that many people show, although whitening treatments and products are nowadays something very popular and very valued; it seems that white teeth are better than yellow, but yellow teeth are not a symptom of disease: usually it is only an aesthetic issue.
Of course, if teeth assume abnormal colouration without an explanation, people have to turn to the dentist, in any other cases colour of teeth varies from person to person, due to different factors. The colour of the teeth depends on thickness of the enamel, the more thick it is the less it makes dentine shine through itself; dentine is a substance that we find right away under the enamel and its colour is usually darker than the enamel one. Usually with age, the enamel become thinner and colouration of dentine become more evident, thus teeth appear darker.
Yellow teeth causes.
Age is one of the reasons for yellow teeth, but there other causes: the colour of the enamel or its thickness is something genetic, so it may be yellow from young ages; foods and drinks may provoke stains on teeth: red wine, coffe, black tea, colas, dark sauces and various fruits have potential to stain teeth because they contain chromogens, pigment-producing substances with a penchant for sticking to tooth enamel.
At the same time acidic foods and beverages can erode tooth enamel and making it easier for chromogens to latch onto the teeth. For this reason it is not recommended to brush teeth before half an hour after eating or drinking acidic or staining food: just after eating enamel become softer and brushing it could make thing worse; it is better to wash the mouth with only water or try to produce saliva and use ita round teeth.
Yellow teeth may be also due to tobacco, cigarettes or pipe smoke; a poor oral hygiene that doesn’t remove plaque e allow tartar to proliferate; certain medications, such as the antibiotics doxycycline and tetracycline, or some antihistamines, drugs for high blood pressure and antipsychotic medications can also stain adult teeth; some diseases or treatments of diseases may cause discoloration of the enamel.
Yellow teeth. Other causes.
Use of eccessive fluoride in childhood may cause yellow adult teeth later; also natural water that contains too much fluoride may has the same effects.
Along with whitening treatments, it’s important to follow a proper oral care, brushing twice a day and flossing once, have a healthy lifestyle and going regularly to the dentist.
