Black Spot on Tooth: Causes and Treatments

  Jan 22, 2024

Teeth – one of the best parts of our face, right? The best curve in our body comes from smiling! But teeth can lose luster when exposed to conditions like black spots and cavities due to our poor lifestyle and eating habits.

Many times, there are black spots on teeth that aren’t cavities but can ruin your picture-perfect smile. So if you also lost confidence in smiling unhesitantly due to these black spots, read more to learn about their causes and treatments.

What is the Black Spot on Tooth?

A cavity and tooth decay are indicated by a little black spot on the tooth. The black material or black dot on the tooth you see is bacteria that has been allowed to grow on the tooth. Similar to overbite and tooth decay, these black spots on teeth can lessen the charm of your smile.

Causes of Black Spot on Tooth

A lot of factors can contribute to a dark spot on a tooth; the most prominent ones are addressed below: 

Dental Decay

First and foremost, allowing plaque and tartar to accumulate on the teeth is probably what caused the tiny black spot on tooth no pain.

If germs, sugar, and acid are permitted to remain on teeth, they will adhere to them and affect the mineral and enamel structure of your teeth causing the black dot on tooth. Maintaining good oral health is integral to having healthy and beautiful teeth. 

The black spot can be prevented from getting worse with prompt diagnosis and treatment. In Canada, cavities are so common that nearly 38% of children have at least one cavity in their permanent teeth. For adults, this number significantly increases.

Brown or black patches are frequently accompanied by the following and may indicate cavities:

  • A toothache
  • Food sensitivity to heat or cold
  • Discomfort during eating

Fluoride Silver Diamine

Silver diamine fluoride stops tooth decay immediately and eliminates microorganisms as a non-invasive cavity treatment. But when tooth rot (decay) happens, it creates a black mark.

Adults do not typically have this cavity treatment because of the potential for discoloration. But occasionally, it’s advised for kids with cavities in their baby teeth or kids with unique issues that make getting a cavity drilled and filled problematic.

The Fluorescence

Brown or black spots on your teeth are a symptom of dental fluorosis, although they only appear in the most severe cases. Too much fluoride intake via drinking water, toothpaste, or even supplements is the cause of this illness.

Other Reasons Behind Your Teeth’s Black Points

Other situations in which we see little black spots on a person’s teeth that are unrelated to decay or fluorosis include:

  • Teeth discoloration may result from specific medical problems or drugs.
  • Bad use of toothbrushes.
  • Dental injuries have the potential to permanently harm teeth.
  • Smoking or using tobacco products heavily.

How to Handle Your Teeth’s Black Spots?

There might be some black spots on your teeth, but they can be easily fixed and shouldn’t worry you too much. Regular dental visits will help you identify the black spot on the tooth in its initial stage and also complement the treatment. 

However, if the black tip is left in place, it will deteriorate more severely and require more intensive care, like a root canal or, in the worst case, tooth extraction.

Major treatments for small black spots on the tooth include:

Treatment With Calcium or Fluoride

Early detection of the black point on your teeth may allow doctors to treat it with fluoride or calcium treatments, which are the least invasive options. If the point is deeper, it could need to be filled in. This is nothing to be concerned about, as fillings are among the most routine dental operations.


When a cavity has formed but is not too deep, fillings are advised. When the tooth’s root is not affected by the cavity, composite fillings function admirably. Since these teeth gap fillings are made to seem like your actual teeth, you won’t even be able to differentiate when you smile.

To eliminate the germs and plaque that have been permitted to build in the black area of your tooth, a filling will need to be drilled into the tooth.

Furthermore, to stop more food particles or debris from entering the cavity and causing further deterioration or discomfort, cover the empty space with a substance (such as composite fillings).

The majority of patients recover from this procedure in a few hours, while others experience soreness for a few days.

Root Canal

When decay has advanced further into the tooth’s root and has lasted for a while, root canal treatment is required. In order to lower the chance of problems, you might need to take antibiotics both before and after treatment if you have an infection.

To make the treatment pain-free, the dentist will numb the area using an anesthetic. The procedure involves the following steps.,

  • Extract the tooth’s nerve and any infected pulp by drilling into the tooth.
  • The tooth’s root canal should be cleaned and shaped.
  • Put something in the tooth.
  • To stop additional damage and let you resume your normal eating habits, fit in and place a crown on the tooth.

Furthermore, you might need to take antibiotics for about a week after the surgery to guarantee that the tooth recovers with minimal danger of infection developing.

Dental Discoloration Cosmetic Procedures

You can repair tooth discoloration with a number of cosmetic treatments if the discoloration is only cosmetic and does not represent a risk to the health of your teeth. Among these are:

  • Expert teeth-whitening procedures.
  • Dental hygiene or using an abrasive material to polish teeth.
  • Products for teeth whitening at home.

The tooth discoloration can be covered with dental bonding, veneers, or a dental crown.

Preventing Black Spots on Tooth

You may avoid getting black spots on your teeth by practicing basic, routine dental hygiene. We consistently emphasize these preventive methods to people because, if they take care of their teeth for less than ten minutes a day, they can avert a great deal of pain and suffering.

Some of the suggestions we offer are ones you are probably already familiar with:

Brush Two to Three Times a Day

You can get rid of any food particles that have managed to stick to your teeth by brushing them in a circular motion two or three times a day. We advise you to brush:

  • For a total of two minutes, spend thirty seconds cleaning each of the four quadrants of your teeth.
  • Before going to bed, brush your teeth to prevent bacteria from growing in the closed mouth, which provides the ideal conditions for decay.

If you’d like, you can use an electric or manual toothbrush. Stylish timers are a common feature of electric toothbrushes; they will notify you after you’ve brushed your teeth for two minutes and allow you to quit.

Floss Once Daily

It is very advised that you floss once a day, preferably right before bed. Try a water flosser instead of normal floss if you don’t like the way string-type floss works for loosening food particles.

If you’d like, you can also use fluoride- or whitening-containing toothpaste and mouthwash.
