These black lines, often found on the chewing surfaces of back teeth, can be both a cosmetic concern and a potential indicator of underlying oral health issues.

Origin of Black Lines: These lines typically result from the accumulation of tartar and plaque in the pits and fissures of molars. Over time, the bacterial film can harden, leading to tartar buildup that appears as dark brown or black stains.

Role of Diet and Hygiene: Poor oral hygiene and consumption of certain foods and beverages, such as sugary foods, red wine, and coffee, can exacerbate these two lines on teeth below. Regular brushing, especially with fluoride toothpaste, and flossing are essential to prevent plaque buildup.

Potential for Decay: If not addressed, these black lines can progress to more severe dental cavities. The trapped bacteria release acids that erode tooth enamel, potentially leading to tooth sensitivity, cavity formation, and tooth decay.

Aesthetic Impact: Beyond health implications, black lines can affect the aesthetic appearance of teeth, leading to self-consciousness about further black lines on one’s smile.

Professional Assessment Needed: If black lines appear, it’s important to consult a dental professional. A dentist can determine if the discoloration or dark spots are superficial or indicate deeper dental caries or other issues.


Regular Dental Hygiene: Best Practices for Prevention

Maintaining regular dental hygiene is crucial for preventing the formation of black lines in the pits of molars and preserving overall oral health. Here are some best practices to incorporate good oral hygiene into your daily routine:

Thorough Brushing

  • Technique: Brush your teeth with a soft-bristled toothbrush and fluoride toothpaste at least twice daily, especially after meals. Be sure to reach the back molars, where black lines are more likely to form.
  • Duration: At least two minutes during each brushing session, cleaning every tooth surface.

Effective Flossing

  • Routine: Floss once a day to get rid of plaque and food particles from between the teeth, areas your toothbrush can’t reach.
  • Method: Use a gentle sawing motion to bring the floss down to the gum line and then curve it around each tooth to remove trapped debris effectively.

Regular Use of Mouthwash

  • Benefits: Incorporating an antibacterial mouthwash into your daily routine can help reduce plaque buildup, kill bacteria that cause tartar, and reach areas that brushing and flossing might miss.

Dietary Considerations

  • Sugar Intake: Limit sugar in food and drinks. Sugar feeds the bacteria in your mouth, increasing the risk of plaque and tartar formation.
  • Balanced Diet: Eat healthy meals rich in vitamins and minerals, which helps to strengthen tooth enamel and improve overall oral health.

Professional Cleanings

  • Frequency: Visit your dentist for professional cleanings and checkups at least twice a year. These visits are vital for removing tartar that can’t be detached by brushing and flossing alone.
  • Early Detection: Regular dental checkups allow your dentist to catch early signs of decay and other dental issues before they become more severe.

By following these best practices, you can effectively prevent the formation of black lines in the pits of your molars and maintain a healthy, clean smile.

Professional Cleaning Techniques: Scaling and Polishing

Professional dental cleaning techniques such as scaling and polishing play a vital role in maintaining oral health and preventing issues like black lines in the pits of molars. Here’s how these professional teeth and techniques contribute:


  • Purpose: Scaling removes plaque and tartar buildup from the tooth surfaces and beneath the gumline. This process is crucial for preventing the progression of gum disease and the formation of black lines caused by tartar buildup.
  • Procedure: Dental professionals use specialized tools such as ultrasonic scalers and hand instruments during scaling. Ultrasonic scalers use vibrations to damage tartar and plaque, while hand scalers scrape them from the teeth.
  • Frequency: The frequency of scaling depends on an individual’s oral health status but is typically recommended during bi-annual dental checkups.


  • Purpose: Following scaling, teeth are polished to smooth the enamel surfaces. Polishing removes any remaining stains and makes it more hard for plaque to adhere to the teeth, thereby reducing the risk of future black lines and decay.
  • Procedure: Polishing is done using a soft rubber cup. Prophylactic paste is applied to the teeth, and the cup spins at high speed, buffing the tooth surfaces to a shine.
  • Benefits: Besides enhancing the aesthetic appearance of the teeth by making them shiny and clean, polishing also leaves the enamel smoother and less likely to harbor plaque.

Fluoride Treatment

  • Purpose: Often included as part of professional cleanings, fluoride treatments can strengthen tooth enamel, which makes it more resistant to decay.
  • Procedure: Fluoride can be applied in gel, foam, or varnish form and is left on the teeth for a few minutes to allow absorption.
  • Benefits: Fluoride fortifies the teeth, diminishing the incidence of cavities and aiding in the protection against acid attacks from plaque bacteria.

Advanced Dental Treatments: Fillings and Sealants

Advanced dental restorations like fillings and sealants are crucial for managing tooth stains, such as black lines in the molars’ pits, and preventing future dental problems. Here’s how these treatments help:

Dental Fillings

  • Purpose: Fillings restore teeth damaged by decay to normal function and shape. When black lines indicate a deeper decay, a filling is necessary to prevent further damage.
  • Materials: Various materials are used for fillings, including composite resins (tooth-colored fillings), amalgam (silver fillings), gold, and porcelain. Each material has its advantages, with composite resins often picked for their aesthetic appeal, as they can be matched to the color of your teeth.
  • Procedure: The process involves getting rid of the decayed tooth material, cleaning the area, and filling the cavity with a filling material. The filling will close off spaces where bacteria can enter, thus preventing further decay.
  • Benefits: Fillings help restore teeth’ integrity and aesthetics. They are essential for teeth compromised by cavities to bring them back to full functionality.

Dental Sealants

  • Purpose: Sealants are a preventive treatment used to protect teeth from cavities, particularly in the pits and fissures of molars where black lines and decay often occur.
  • Materials: Sealants are made from plastic and used on the chewing surfaces of the back teeth.
  • Procedure: The application is straightforward and painless. The tooth’s surface is cleaned and dried, a solution is applied to slightly roughen the surface to help the sealant bond to the teeth, and then the sealant is painted on and hardened with a light.
  • Benefits: Once applied, sealants act as a barrier, protecting enamel from plaque and acids. They are especially beneficial for children and teenagers whose newly erupted permanent teeth need protection against decay.

Home Remedies: Safe and Effective Methods

Certain home remedies can be safe and effective when it comes to protecting your oral health and addressing minor issues like black lines in the pits of molars. While these should not replace professional dental care, they can complement your good oral hygiene routine well. Here are some practical home remedies to consider:

Proper Brushing Technique:

  • Method: Use a soft toothbrush and fluoride toothpaste to brush your teeth, focusing on the back molars where black lines tend to form. Brush at least 2 times daily, especially after meals, to remove food particles and plaque.
  • Benefit: Regular and proper brushing prevents the accumulation of plaque that can cause tartar and black lines.

Baking Soda Toothpaste:

  • How to Use: Combine baking soda in small amounts with water to create a paste. Use this mixture occasionally to gently scrub the teeth.
  • Benefit: Baking soda is a mild abrasive that can help remove surface stains on teeth, reducing the appearance of black lines.

Oil Pulling:

  • Method: Swish a tbs. of oil, like coconut, sesame, or sunflower oil, in your mouth for around 15-20 minutes, then spit it out and rinse with warm water.
  • Benefit: Oil pulling can help in reducing plaque and bacteria in the mouth, potentially minimizing the formation of black lines.

Apple Cider Vinegar Rinse:

  • How to Use: Dilute apple cider vinegar (one part vinegar to two parts water) and swish the solution in your mouth for a minute. Rinse with plain water afterward.
  • Caution: Use this rinse sparingly, as vinegar is acidic and can erode tooth enamel if used too frequently.
  • Benefit: Apple cider vinegar has antibacterial properties that can help cleanse the mouth and reduce plaque buildup.


  • Importance: Drink enough water throughout the day to help wash away food particles and bacteria from the mouth.
  • Benefit: Staying hydrated promotes saliva production, which naturally helps cleanse the teeth and gums, reducing the risk of plaque buildup.
