The teeth change in color over time. You may notice that your once white teeth now have turned a shade duller. This is normal and there are many reasons why this change happens. Fortunately, people who wish to make their teeth whiter have many options for doing so.
Before jumping into that, here is an explanation as to why the teeth become yellow over time.
The outer covering of the teeth is called the enamel. The enamel serves as the teeth’s protection. Inside the teeth is the dentin, which is naturally yellow in color. Over time, the enamel becomes thinner and because it’s semi-translucent, the color of the dentin shines through. This is one reason the teeth turn yellow.
Cigarettes contain many chemicals including nicotine, which turns yellow once mixed with oxygen. Nicotine in smoke, which passes through the mouth and finds its way to the enamel pores and stains it. Long-term smoking may cause severe levels of teeth yellowing according to Dentaly.org.
Certain food stains the teeth. If you often consume them, then there’s a big chance your teeth aren’t as white and shiny as they used to. Coffee, tea, berries, and dark-colored sauces are some of the food that stain the teeth. Some may not cause teeth discoloration, but because they contain acid, they cause enamel thinning.
Proper Oral Hygiene to Prevent Teeth Discoloration
Proper oral hygiene helps avoid discoloration of teeth, or if not, delays it. Brush the teeth at least twice a day to remove plaque that eats away the teeth and to avoid teeth stains. Miller Comfort Dental suggests visiting a dentist in Lakeville, MN for professional cleaning every six months.
The American Dental Association (ADA) states that teeth whitening products and procedures are effective. You can choose between over-the-counter teeth whitening products, such as gel, strips, and toothpaste, and professional teeth whitening procedures to make your teeth whiter. The ADA recommends seeing the dentist for proper advice before using products that contain bleaching agents. On the other hand, professional teeth whitening procedures may be more expensive but are safer and more effective.
There is a reason behind those yellow teeth. Whatever it may be, you can make them whiter with teeth whitening products or a dental procedure.
