Why Do Teeth Begin To Look Brown If They Become Unhealthy?

Posted on 6/7/2021 by Adam Bartlett
Why Do Teeth Begin To Look Brown If They Become Unhealthy?When teeth become infected with bacteria, they tend to become brownish in color. Naturally, your teeth are supposed to be white and free from any stains. However, tooth decay, fluorosis, and tartar are some of the things that might stain your white teeth and make them look brownish.


When you have tooth decay, your teeth might have brown spots. In most cases, these spots develop as a result of eating starchy and sugary foods and drinks. Most of these foods create a plaque that sticks on the surface of your teeth, damaging them and staining the color. The continued presence of plaque on your teeth will make them turn brownish. Besides, it will also destroy the enamel, exposing the rest of your tooth. The brown spots might also be a result of the dentin underneath the teeth, which has a darker shade when exposed.


As much as fluoride is meant to protect your teeth from decay, too much of it can discolor your teeth. Fluorosis is a condition caused by excessive intake of fluoride. Mostly, the appearance of a blackish line or streaks is an indicator of mild fluorosis. However, brown, black, or grayish pits and patches on top of a tooth surface indicate severe fluorosis. Despite the fact that your teeth might look damaged, fluorosis is a cosmetic condition that only affects the appearance of your teeth. However, this condition shouldn't be ignored because it can also be a sign of tooth decay.


When excessive plaque builds up on your teeth, it hardens into tartar. This is a brownish substance that can also stain your teeth. Mostly, tartar appears in between your teeth and along the gum line, causing significant damage to your gum and teeth. To get rid of it, you should brush your teeth twice a day and floss regularly.
