Why Are Your Teeth Yellow?

Yellow teeth can be a major turn-off. It leaves one looking dowdy and ill-kept. One major cause of tooth discolouration is smoking or chewing tobacco. The components that make up smoking products include ammonia, hydrogen cyanide and carbon monoxide as well as nicotine and tar. When a cigarette is lit, these substances burn, causing a change in their chemical properties. The smoker inhales and smoke passes through his/her mouth, leaving sticky residue on the teeth.

Not following a routine of oral hygiene like inadequate brushing and flossing to remove plaque and stain-producing substances can cause tooth discoloration.

Certain food and drinks are also responsible for causing yellow teeth.  Black tea is full of tannins that promote teeth staining and it is considered one of the most problematic drinks for teeth discoloration. Green tea and herbal teas are believed to be much less likely to cause problems.

The phosphoric and citric acids in colas and many other sodas, along with their massive amounts of acidic sugar, all wear down tooth enamel. Commercial fruit juices are also much more acidic than most people realize. Even healthy fruits, berries and vegetables like pomegranates, blueberries and beetroot are loaded with strongly colored compounds such as polyphenols which stain teeth.

Hard candies and brightly colored sweets that you chew are a big problem for teeth staining, not just because of their high sugar content, but also because of the length of time they stay in your mouth. Any other foods and drinks that can stain your tongue, are likely to slowly stain your teeth.

Red wine is well known teeth stainer due to its deeply colored polyphenols and tannins, whereas white wine is also a problem due to its tannins and acidic nature. Brightly colored sauces like curries and tomato sauce can attach to porous dental enamel. Table condiments like soy sauce, balsamic vinegar and ketchup are believed to contribute to teeth staining.

Several diseases that affect  enamel (the hard surface of the teeth) and  dentin (the underlying material under enamel) and treatments like head and neck radiation and chemotherapy can cause tooth discolouration.

Medication like antibiotics tetracycline and doxycycline are known to discolor teeth when given to children whose teeth are still developing. Mouth rinses and washes containing chlorhexidine and cetylpyridinium chloride can also stain teeth. Antihistamines (like Benadryl), antipsychotic drugs, and drugs for high blood pressure also cause teeth discoloration.

Some of the materials used in dentistry, such as amalgam  restorations, especially silver sulfide-containing materials, can cast a gray-black color to teeth. Excessive fluoride, damage from a fall as well as trauma can also cause discoloration to teeth.

As one ages the outer layer of enamel on the teeth gets worn away revealing the natural yellow color of dentin. Otherwise some people have naturally brighter or thicker enamel than others, genetically.

By making a few simple lifestyle changes, you may be able to prevent teeth discoloration like cutting down or quitting smoking and giving up excessive coffee and cola. Remember to do 2 simple things after eating or drinking any tooth-staining food or drink--have a big sip of water after you’ve finished your meal or drink and swirl it around your mouth to clear away any acids or staining compounds. Also, actively try and get more saliva into your mouth after eating and let it move over your teeth. It’s easy to do after a sip of water and saliva is your mouth’s natural defense against enamel erosion, staining and cavities.

Also, improving your dental hygiene by brushing and flossing regularly and getting your teeth cleaned by a dental hygienist at your nearest Trinity Dental Center every 6 months will help you maintain a white smile.
