1. Most of us know that certain beverages can cause staining, especially beverages which are known to have chromogenic agents. This would be drinks such as coffee, tea, red wine, and colas. Dental websites on the internet typically recommend to brush with toothpaste as soon as possible after drinking one of these popular libations. Whitening can and will remove these stains, but unless the whitening process is continued on a regular basis, these stains will return with the continued consumption of these beverages. A routine whitening should be considered to keep these type of stains at bay.
2. Smoking is another culprit, and one which causes yellow and brown stains to appear on your teeth. Over time, the smoking of cigarettes, pipes, or cigars can cause extreme staining. Even smokeless tobacco, such as chew or snuff can cause discoloration. A thorough cleaning and whitening will remove these stains, but continuing to smoke will cause them to reappear. You will need to stay on a regular whitening schedule to stay on top of these type of stains.
3. There are medications which can also cause your teeth to change colors. A popular antibiotic called tetracycline should be avoided by children under the age of 8, and also by pregnant women. A dentist will need to advise whether whitening will be advantageous for this condition. Tetracycline-stained teeth are difficult to bleach. This drug-induced stain resides in the dentin layer, which lies under the enamel where permanent staining can occur.
4. A little known fact is children who have not yet formed their adult teeth, may be at risk for discoloration or color changes if they ingest Fluoride. Color changes can range from milky white to brownish. Dentists suggest avoiding Fluoride in toothpaste until your child is able to rinse and spit while brushing, at about 2 ½ years of age. Bleaching for adults can be affective, depending on the severity of the stains.
5. Most of us are aware aging can cause your teeth to darken, but that does not mean there is no hope. Although you may never see snowy white again, most bleaching systems can bring your teeth up several shades of white.
In conclusion, most of our bad habits cause normal staining which can be reversed with a quality tooth whitening system. Illness, medication, decay, or trauma may warrant a visit to your dentist.
