Oil pulling is an ancient practice that has gained popularity in recent times. It involves swishing a tablespoon of oil, usually coconut oil, in the mouth for a period of time, typically 15 – 20 minutes. Dental fillings, on the other hand, are used to restore teeth that have been damaged by decay or other factors. There is a concern among some people about whether oil pulling could have an adverse effect on dental fillings. To understand this, it is necessary to look at the properties of both oil pulling and dental fillings.
Composition and Characteristics of Dental Fillings
Amalgam Fillings
Amalgam fillings are made of a mixture of metals, mainly mercury, silver, tin, and copper. They are known for their durability and ability to withstand the forces of chewing. These fillings have been used for a long time in dentistry. The metal composition of amalgam fillings is relatively stable. However, they can be affected by certain chemicals or substances.
For example, exposure to acidic substances over a long period can cause some corrosion of the amalgam. But when it comes to oil pulling, coconut oil is not highly acidic. In fact, coconut oil has a relatively neutral pH. So, from a chemical reactivity perspective, it is less likely that oil pulling with coconut oil would directly cause harm to amalgam fillings.
Composite Fillings
Composite fillings are made of a resin material. They are popular because they can be color – matched to the natural tooth, making them more aesthetically pleasing. Composite fillings are bonded to the tooth structure. The bonding process is crucial for their long – term success. When it comes to oil pulling, the concern might be whether the oil could disrupt the bond or cause any softening of the composite material. However, composite resins are designed to be resistant to a variety of substances in the oral environment. Coconut oil is not a solvent for the resin used in composite fillings. So, in general, it is not expected that oil pulling would have a significant impact on the integrity of composite fillings.
Glass Ionomer Fillings
Glass ionomer fillings are another type of dental filling. They have the advantage of releasing fluoride over time, which can help prevent further tooth decay. These fillings are somewhat more soluble in acidic conditions compared to amalgam and composite fillings. But again, coconut oil is not acidic, and there is no evidence to suggest that oil pulling with coconut oil would cause any dissolution or harm to glass ionomer fillings.
The Process of Oil Pulling and Its Interaction with Fillings
Swishing Motion
During oil pulling, the swishing motion of the oil in the mouth is gentle. It is not a forceful action that would physically dislodge a filling. Dental fillings are placed securely in the tooth cavity, and the adhesive or bonding used for different types of fillings is designed to withstand normal oral activities such as chewing, talking, and even some mild trauma. The swishing motion during oil pulling is much less forceful than the forces exerted during chewing, so it is highly unlikely to cause a filling to become loose or fall out.
Oral Microbiota and Fillings
Oil pulling is believed to have an effect on the oral microbiota. It is thought to reduce the number of harmful bacteria in the mouth. While the presence of bacteria can potentially affect the health of dental fillings over time (for example, bacteria can produce acids that may corrode fillings), oil pulling may actually be beneficial in this regard. By reducing the bacterial load, it may help to maintain a healthier oral environment around the fillings, rather than causing harm.
Is Oil Pulling Harmful to the Filling?
Temperature Sensitivity
One potential concern could be if the oil used for pulling is very cold. Some people might use refrigerated oil. Extreme cold can cause tooth sensitivity, especially in teeth with fillings. This is because the different materials in the filling and the tooth may expand and contract at different rates in response to temperature changes. However, this is not a direct harm to the filling itself but rather a potential discomfort to the patient. To avoid this, it is advisable to use oil at room temperature for oil pulling.
Allergic Reactions
Although rare, some people may be allergic to the oil used for oil pulling, such as coconut oil. In such cases, if an allergic reaction occurs in the mouth, it could potentially affect the area around the filling. For example, swelling or inflammation in the gums or soft tissues near the filling could potentially put pressure on the filling or disrupt the normal oral environment around it. However, this is an allergic reaction – related issue rather than a direct harm caused by the oil pulling process to the filling.
Conclusion
In conclusion, based on the current understanding of the properties of dental fillings and the process of oil pulling, there is no strong evidence to suggest that oil pulling is harmful to dental fillings. However, it is always important to practice oil pulling in a proper manner, using appropriate oils at the right temperature, and being aware of any potential allergic reactions. If a patient has any concerns about the effect of oil pulling on their fillings, it is advisable to consult their dentist for personalized advice.
