If your teeth aren’t looking as bright as you’d like, there could be several reasons behind the discoloration. A dentist has revealed the most common culprits behind yellowing teeth, and how to stop it.
We all know that brushing twice a day isn’t enough to keep our teeth perfectly white. Good oral hygiene includes flossing, using mouthwash, and even simple tricks like drinking through a straw to prevent stains. But what if you’re doing everything right and your teeth are still losing their brightness?
The dental experts at Mawson Dental Care have identified seven key reasons why teeth turn yellow. Understanding these causes can help you take the right steps to maintain a whiter, healthier smile.
1. Aging
Unfortunately, aging affects more than just our skin, it impacts our teeth, too. Over time, the protective enamel on your teeth wears down, exposing the yellowish dentin underneath. This natural process makes teeth appear more yellow as you get older.
2. Smoking
Tobacco, nicotine, and tar found in cigarettes are notorious for staining teeth. Over time, these substances can turn teeth yellow, or even brown. If you want to keep your teeth white, quitting smoking is a crucial step.
3. Poor Oral Hygiene
If you’re not brushing and flossing properly, stains will build up. Dentists refer to this as “extrinsic tooth staining,” which happens when food, drinks, and plaque discolor the outer layer of your teeth. The good news? This type of staining is preventable with consistent brushing, flossing, and dental cleanings.
4. Dental Procedures
Ironically, some dental treatments can cause discoloration. Materials like amalgam used in certain fillings and restorations may leave a grayish-black tint on your teeth. While this isn’t harmful, it’s something to be aware of when considering dental work.
5. Medications
Some medications, especially antibiotics like tetracycline can cause tooth discoloration, particularly in children under eight. However, adults can also experience staining from certain medications. The good news? Whitening treatments, both professional and natural (like oil pulling with coconut oil), may help restore brightness.
6. Illness
Certain illnesses and medical treatments (such as chemotherapy) can affect tooth enamel and dentin, making teeth appear more yellow. If your health is impacting your smile, consult your dentist for whitening options.
7. Genetics
Sometimes, yellowing teeth are simply in your DNA. Some people naturally have thinner enamel, making the underlying yellow dentin more visible. While you can’t change your genetics, cosmetic options like veneers or composite bonding can help you achieve a brighter smile.
How to Keep Your Teeth White
While some causes of yellowing are unavoidable, good oral hygiene, quitting smoking, and professional whitening treatments can significantly improve the appearance of your teeth. If discoloration persists, talk to your dentist about the best whitening options for you.
