Benefits of Teeth For Oral Health: Black Tea

As the name suggests, this tea is darker in color than the other options.

This tea contains compounds that are effective in fighting oral bacteria such as Lactobacillus and Streptococcus mutans.

These bacteria cause cavities and the compounds in black tea fight them in order to give you a healthier smile.

They help to reduce the levels of the two harmful bacteria in plaque, as a result, preventing cavities as well as gum disease.

It stopped growing and releasing more acid.

Considerations While Drinking Tea

Tea is great for your oral health but it is always good to keep some considerations in mind while you drink it constantly.

Usually, one to three cups a day is more than enough and can give you the required benefits you want to avail yourself.

It is also important to remember that some compounds in tea are not exactly great for your teeth.

While tannin has some good properties, it is also what gives the tea its color.

Therefore, this yellow, brownish substance can leave a yellow stain on your teeth which can eventually turn darker over time.

In order to avoid that, brush your teeth or at least rinse your mouth after you have had a cup of tea.

If the staining worsens, you may have to use a teeth whitening treatment in order to get rid of the discoloration.

Thus, if you drink too much tea, you will be prone to getting yellow teeth.

Other than that, tea may be bitter or strong to drink on its own.

Therefore, several people may prefer to add sugar, honey or even lemon to acquire it to their tests.

This, however, is a bad idea.

These add ons can be behind the erosion of your enamel.

Hence, you should best stay away from the like of sugary or acidic add ons that will mask the benefits of tea and pose more health problems instead.


Drinking one or two cups of tea on a daily basis can help reap the benefits of tea for your oral and physical health.

Therefore, this is not a thing to ignore and if you drink no healthy beverage, maybe starting with a cup of green tea after today’s dinner is a good option.
