Recently, oil pulling has gained popularity as a natural remedy for improving oral health. Some people say it can whiten teeth, freshen breath, and even reverse tooth decay. Dentists usually have standard procedures to help patients with tooth decay like fluoride treatments and fillings for smaller cases, with crowns and root canals for advanced stages.

It’s unlikely oil pulling would be recommended. But can swishing oil in your mouth truly heal cavities? Here’s what scientific research reveals about this practice.​

What Is Oil Pulling?

Originating from ancient Indian medicine, oil pulling involves swishing edible oils like coconut, sesame, or sunflower oil in the mouth for about 10 to 20 minutes before spitting it out. Oil pulling supporters believe this process “pulls” toxins and bacteria from the mouth, promoting oral and overall health.​

Understanding Tooth Decay

To see whether oil pulling can reverse tooth decay, it’s essential to understand how decay occurs. Tooth decay starts when bacteria in the mouth feed on sugars, producing acids that erode the enamel—the tooth’s protective outer layer. Over time, this erosion can lead to cavities.​

Reversing tooth decay typically involves remineralization, where minerals like calcium and phosphate are redeposited in the enamel. This process can halt or even repair early decay but is limited to the initial stages before cavities form.​

What Does the Research Say?

Bacterial Reduction

Some studies suggest that oil pulling can reduce harmful oral bacteria. For instance, a study found that oil pulling with coconut oil was as effective as chlorhexidine, a prescription mouthwash, in reducing Streptococcus mutans, a primary bacterium responsible for tooth decay. ​

Plaque and Gingivitis

Research also indicates that oil pulling may help reduce plaque accumulation and gingivitis. A 2020 study demonstrated that virgin coconut oil used in oil pulling significantly decreased plaque formation and plaque-induced gingivitis. ​

Can Oil Pulling Reverse Cavities?

Despite its potential benefits in reducing bacteria and plaque, there’s no scientific evidence that oil pulling can reverse existing cavities. Remineralization requires the presence of minerals like calcium and phosphate, which oils lack. Therefore, while oil pulling may support oral hygiene, it cannot restore lost enamel or fill cavities. ​

Risks and Considerations

Oil pulling is generally safe, but it’s not without risks. Rare cases of lipoid pneumonia have been reported when oil is accidentally inhaled into the lungs during the practice. Additionally, relying solely on oil pulling without proper dental hygiene can lead to worsening oral health issues.​

When to Consult a Dentist

While oil pulling can be a supplementary oral hygiene practice, it should not replace regular dental care. Consult a dentist if you experience:​

  • Persistent Tooth Pain: May indicate cavities or other dental issues.
  • Bleeding Gums: Could be a sign of gum disease.
  • Sensitivity: May result from enamel erosion or cavities.​

Regular dental check-ups and professional cleanings are essential for maintaining oral health.​

Traditional Dental Treatments for Tooth Decay

Dentists use several proven methods to treat tooth decay, depending on how advanced the decay is. Here’s what they typically do at each stage:

1. Fluoride Treatments for Early Decay

When tooth decay is caught early—before a cavity fully forms—dentists may use fluoride treatments to help remineralize enamel. These treatments often contain higher concentrations of fluoride than what’s found in toothpaste or over-the-counter rinses.

Common forms: fluoride gels, varnishes, foams, or prescription toothpaste.

Goal: strengthen enamel and stop decay from progressing.

2. Fillings for Cavities

Once a cavity has formed, remineralization won’t fix it. The dentist will typically recommend a filling. During the procedure, the decayed portion of the tooth will be removed with a drill or laser. Then it’s filled with either composite resin, gold, or ceramic. Fillings are the most common treatment for mild to moderate decay.

3. Crowns for Extensive Decay

If a cavity is too large for a filling, the tooth may be structurally weak. In that case, a dentist might place a crown. The decayed area is removed, the remaining tooth is reshaped, and a custom-made crown (cap) is placed over the tooth to restore strength, shape, and function. Materials used include porcelain, metal, or a combination of both.

4. Root Canal for Decay That Reaches the Pulp

When decay reaches the soft tissue (pulp) inside the tooth, it can cause infection and pain. To save the tooth, dentists perform a root canal to remove the infected pulp and seal it.

5. Tooth Extraction for Severely Damaged Teeth

If a tooth is too decayed to save, it may need to be extracted (removed). Dentists will then discuss options to replace the tooth, such as dental implants, bridges and partial dentures.

Oil pulling may offer some oral health benefits, such as reducing harmful bacteria, plaque, and gingivitis. However, there’s no scientific evidence to support claims that it can reverse tooth decay or cavities. For effective prevention and treatment of tooth decay, it’s crucial to maintain proper oral hygiene practices, including brushing with fluoride toothpaste, flossing, and regular dental visits.​

Incorporating oil pulling as a supplementary practice can be beneficial, but it should not replace conventional dental care methods.
