Brown Spots On Teeth: What To Do And How To Clean Them

July 29, 2023

Brown spots on teeth can range from yellowish-brown to black-brown. The spots can vary in shape and size. Some may look like irregular, blotchy patches, while others may look like lines. If you struggle with brown spots on your teeth, don’t worry! Read on to find out everything you need to know about brown spots, especially how to clean them!

Why Do I Have Brown Spots On My Teeth?

There are many possible causes of brown spots. Here are some common ones:

Food and drinks

Coffee, tea, red wine, and cola are just a few of the many beverages that can cause tooth discoloration. As for food to avoid, blueberries, blackberries, and pomegranates are on the list.

Nicotine and tobacco products

A study has found that if you chew tobacco or smoke cigarettes or cigars, you are more likely to experience tooth discoloration and feel unsatisfied with the color of your teeth.


Plaque, a soft film of bacteria that coats your teeth, can accumulate and harden, becoming tartar. Tartar appears as yellow to brown discoloration along the gum line.

Tooth decay

In cases of tooth decay, brown spots may eventually turn black as the damage progresses.


The older you get, the darker and spottier your teeth become. This is part of the natural aging process.


Some people are just born with teeth that are more brown than others. In rare cases, there are also genetic disorders, like dentinogenesis imperfecta, which result in people being born with brown spots in their teeth.

Previous Dental Work

Old metal, silver, or white fillings can turn brown over time. 

Root Canal

Root canal treatment is a dental procedure that relieves pain caused by an infected or abscessed tooth. This process involves the removal of the inflamed pulp. However, a tooth that requires this procedure may turn and stay brown because the root of the tooth dies and darkens.

Chlorhexidine mouth wash

Those taking this prescription mouth rinse for gum disease may be subject to its side effect, brown spots on teeth. Other possible side effects are altered taste perception and tartar build-up.


Antibiotics like tetracycline and doxycycline can stain teeth. However, this most often occurs in children whose teeth are still developing. Tetracycline is used to treat infections caused by bacteria including pneumonia and other respiratory tract infections; certain infections of the skin, eye, lymphatic, intestinal, genital, and urinary systems; and certain other infections that are spread by ticks, lice, mites, and infected animals. Doxycycline is an antibiotic that’s used to treat infections including chest and dental infections, skin infections and conditions like rosacea, and sexually transmitted infections (STIs).

Celiac Disease

Celiac Disease is more commonly known as an allergy to gluten. It is thought to affect 1 in 100 people worldwide.


Fluorosis is a common cause of brown spots on the teeth of children and is a result of too much fluoride.


If the nerves of your teeth are damaged due to trauma, brown spots may appear. In severe cases, the entire tooth may turn brown. Teeth are also known to turn gray in certain instances of trauma.

8 Ways To Remove Brown Spots On Teeth

Thankfully, most brown stains can be removed. Here are 8 things you can try to remove those pesky spots:

Good Oral Hygiene

Before you add anything to your oral hygiene routine, don’t forget to master the basics! Brushing, rinsing with mouthwash, and flossing daily are important to prevent the formation of and remove any brown stains on your teeth.

The Proper Way To Brush Your Teeth:

  1. Starting with the outer surfaces, gently brush your upper and then lower teeth. Go tooth by tooth so you don’t miss any spots.
  2. Tilt your brush at a 45° angle. Brush against the gumline and move the brush back and forth using short, tooth-wide strokes.
  3. Brush the inner surface of your teeth. Use the same 45° angle back and forth technique.
  4. Clean the chewing surfaces of your teeth, especially the tops of your back teeth.
  5. For fresher breath, brush your tongue

Activated Charcoal

Activated charcoal is one of the most popular DIY ingredients for teeth whitening. After undergoing a high-temperature oxidation process, this fine powder becomes highly porous. Its porous nature enables it to effectively bind to surface stains on your teeth. Once the charcoal is removed, it carries away the stains, leaving your teeth noticeably cleaner and more radiant.

  1. Create a paste by mixing activated charcoal with warm water.
  2. Apply the paste directly to your teeth, using a dabbing or tapping motion rather than rubbing it in.
  3. Allow the activated charcoal paste to remain on your teeth for three to five minutes.
  4. After the designated time, thoroughly rinse your mouth and brush your teeth with your regular toothpaste.
  5. Repeat this process once daily for a duration of three to five consecutive days, every three to four months.

However, it is much more convenient and hassle-free if you use teeth whitening products that already contain activated charcoal!

Dental Check-Ups and Cleaning

For stains caused by tartar or medical conditions, one might need to visit a dentist. Dentists can use instruments to scrape, blast, or rub the stain away from your teeth. For more stubborn and seemingly permanent brown spots, white composite fillings, veneers, or crowns may be necessary.
