There are a number of reasons that can cause teeth to change color . Teeth can darken or yellow due to medications. chemotherapy, trauma to the teeth, smoking cigarettes, cigars, vaping, certain food, coffee, tea , and age. Many years ago when a woman was pregnant and developed and infection tetracycline was prescribed. This created an entire generation of kids with grayish dark teeth when there permanent teeth erupted. Physicians today are well aware of this today and other antibiotics are used. Tetracycline stained teeth normally will need deep bleaching or need to be covered with porcelain laminates or crowns to block out the gray color to the teeth.
Best way to darken your teeth is smoking. The tar and nicotine in Cigarettes, vaping and cigars cause a grayish black stain that penetrates the enamel and is very difficult to safely whiten the teeth again with bleaching. When you smoke you are also slowly heating the roof of you mouth and increasing your change of cancer in your lungs and in your mouth. Smoking Marijuana causes teeth to stain also.
Coffee tea and red wine have color pigments that attach to your enamel darkening teeth. As we age the enamel outer layer of our teeth will thin reveling the yellower dentin layer. When we get older the pulp chamber inside our teeth gets smaller and more dentin replaces it. This prevents light from traveling through the teeth making the teeth darker and more brittle.
In order to keep you teeth white economically as you age, you need to start with whitening products in your twenties.
American Dental association approved whitening tooth pastes, commercial bleach strips or take home bleaching trays made by your dentist. Some of this information was taken from www.mouthhealthy.org and the rest from treating patients with stained teeth in my practice.
