Everyone love to flaunt pearly white teeth, isn’t it? If you become conscious of your yellowing teeth when someone makes you laugh – it’s the right time to consider getting to the bottom of what’s causing the yellowing.
If your entire family has yellow teeth, then most likely it is genetic. Let me tell that it’s the thickness of the outermost layer of the teeth which is genetically transmitted, and not the color. A thinner enamel layer will make the yellow dentin layer more visible.
With age the teeth turn yellow. As one gets older the outer layer of enamel wears away and becomes thinner. This prompts the dentin’s yellow colour to show through and your teeth appear yellower.
If you took antibiotics like tetracycline or doxycycline before you turned eight, it’s likely that your permanent teeth have striated or banded stains on them. If a pregnant woman takes these antibiotics then it will create yellow stains on her child’s teeth. The reason is that these antibiotics merge with the mineral structure of the enamel.
Excessive fluoride intake can be brought on by high fluoride levels in water, a child devouring excessive fluoride toothpaste or fluoride supplements taken by mouth. Yellowish stains on the teeth is the most likely outcome.
Foods and drinks
Some of the foods and drinks that can cause teeth discolouration are: blueberries, cherries and drinks like coffee, tea, colas and wines. Even apples and potatoes can make your teeth yellow. The colouring molecules in these foods and drinks stick to the enamel and cause yellow staining.
Smoking or chewing tobacco can cause extrinsic stains on the enamel of the teeth. Tobacco has countless hard-to-remove staining elements that slowly make the teeth yellow and spoil the look of your teeth.
Poor oral hygiene
If you often skip brushing and flossing you allow stains from coffee, tobacco, etc. to develop and tartar to build up on teeth. This results in teeth turning yellow.
Dental restorative materials such as amalgam (silver fillings) can ooze out over time and get lodged in the enamel, to turn your teeth yellow.
Particular diseases and infections in pregnant mothers impede the development of enamel and the underlying dentin, to trigger yellowing of teeth later in the child. Treatments such as chemotherapy and radiation to the head and neck can make the color of teeth yellow as well.
Any injury caused to teeth due to trauma like sudden fall or accidents can lead to bleeding in the innermost layer of the tooth (pulp chamber). Blood clot and remnants of decomposed pulp tissue may penetrate the tubules of the dentin causing staining of the dentin, in turn making the tooth color yellow. Trauma in children can mess up with enamel formation and cause yellowing of their teeth.
