Dentist explains why teeth turn yellow, even if you brush them regularly
Many dream of a bright white smile and healthy teeth. However, even with regular brushing, achieving this can sometimes be difficult, and teeth may still appear yellow. There is a logical explanation for this, reports the Daily Express.
Why do teeth turn yellow with constant brushing
Excessive brushing
Dentist Zainab Mackie explained that the more you try to whiten your teeth, the worse it can affect your oral health.
In particular, many people have yellowish teeth no matter what they do. Often, people make one mistake when it comes to brushing their teeth, which causes more harm than good.
"You might be brushing too hard, stripping away that white enamel," the expert said.
It is known that over-brushing damages the hard outer layer of the teeth - the protective coating that shields them from damage.
Aggressive brushing can harm the teeth and expose the dentin layer beneath, which has a yellow-brown color.
Diet
Dr. Mackie added that another reason for yellowing teeth is diet and lifestyle. This includes smoking, as well as consuming certain drinks and snacks.
It is known that some medications also cause teeth to yellow, including antibiotics, blood pressure medications, and antihistamines.
Acidic fruit juices can also stain teeth. However, using a straw can help protect enamel, even when consuming sodas or coffee.
How often should you brush your teeth
You should brush your teeth for at least 2 minutes. The duration directly affects the effectiveness of oral cleaning, which reduces the risk of cavities and gum diseases.
Use toothpaste with the correct fluoride concentration. The fluoride content should always be indicated on the packaging. Adults are recommended to use toothpaste containing at least 1350 ppm of fluoride. If you have sensitive teeth, it is not recommended to use toothpaste containing fluoride.
It is also advisable to replace your toothbrush every 3 months, as bacteria accumulate on it over time.
