A dry socket is a common post-extraction issue that can be caused by infection, trauma, or problems with the jawbone. When a tooth is extracted, the wound should be protected by a blood clot to heal properly. Unfortunately, a dry socket can occur if this fails to develop or becomes dislodged before healing occurs. Food: Starchy food like pasta or potatoes can stick to your teeth. They can also become sugar in the mouth, attracting bacteria in your enamel and later producing stains. Drinks: Drinks like coffee, tea, dark-coloured sodas, and red wine contain tannins which are organic substances that can cause teeth discolouration. Tobacco: Tobacco use, whether cigarettes or chewing tobacco, can cause stained teeth. Tar and nicotine from the smoke can penetrate tooth enamel through tiny pores, drastically discolouring them over time. Poor dental hygiene: Poor oral care, like inadequate brushing or flossing, can lead to plaque buildup, resulting in stained and discoloured teeth. Disease or trauma: Staining can be caused by several factors, such as illnesses or injuries that interfere with tooth enamel development- leading to discolouration over time. Medical treatments: Hypertension medications, chemotherapy and antihistamines can cause discolouration of the tooth enamel if taken for an extended period.
