What are large dental cavities?Large dental cavities refer to the condition where teeth have been decayed for a long time without timely treatment. As a result, harmful bacteria continue to grow, eroding and creating holes in the teeth. In more severe cases, the decay reaches the pulp.

Large cavities typically occur in the back teeth. Due to their deep location, it is challenging to maintain proper oral hygiene. The cavities are often not visible to the naked eye. Patients usually become aware of them when they experience pain in the oral area. Large dental cavities not only affect the aesthetics of the mouth but also pose other risks to oral health:

  • Cause toothache and damage to the nerve.
  • Result in long-term pulp inflammation, erosion, and pulp death.
  • Can lead to infection in the oral cavity.
  • Increase the risk of tooth decay, fractures, or even tooth loss.

What are the causes of large dental cavities?

The causes of large dental cavities are often attributed to the following factors:

  • Development of harmful bacteria on the teeth.
  • Poor oral hygiene after eating, allowing food particles to stick to the teeth and create a favorable environment for bacterial growth.
  • Prolonged presence of food on the teeth can also cause discoloration and enamel loss, eventually leading to deep cavities.

In general, the causes of large dental cavities are rooted in a lack of oral care, improper brushing techniques, and irregular dental hygiene habits. Additionally, an unhealthy diet also contributes to the development of large cavities.

Symptoms of large dental cavities

The symptoms of large dental cavities can be observed with the naked eye. When the tooth enamel and dentin are damaged, the cavities can be easily seen using a dental probe.

Consuming cold, spicy, or hot foods can cause sensitivity and toothaches.

The cavities contain bacteria and leftover food, causing bad breath. Over time, this leads to an unpleasant odor in the mouth.

Causes of large dental cavities

Usually, when teeth have minor cavities, dentists will fill them to restore and protect the teeth.

Dental amalgam is a technique used to fill cavities with dental materials, aiming to prevent bacteria and food particles from entering and causing infection. This is a common method in treating cavities, with reasonable costs, often applied to cases of minor cavities. However, for large cavities, dental amalgam is not the optimal solution. Although it can still be done, its durability is not high.

With large cavities, the area that needs filling is extensive, reducing the adhesive capacity of the filling material. When subjected to regular chewing forces over an extended period, the filling material is prone to dislodging. Therefore, dentists often advise clients to consider dental crowns, veneers, or use the Inlay/Onlay technique for treatment.

Some common and suitable materials for filling large cavities

Although dentists do not prioritize filling large cavities, there are still cases where clients prefer this technique. Below are some common and most suitable materials for filling large cavities.



Amalgam is a dental filling material composed of a mixture of mercury, tin, silver, etc. It is a traditional filling material with high strength and good longevity. Therefore, it used to be very popular in previous years.

Therefore, for very large dental cavities, the durability and hardness of Amalgam will ensure better performance in terms of time and effectiveness. However, the disadvantage of Amalgam is that it has a metallic color and is quite different from the natural color of teeth. Therefore, Amalgam is usually only suitable for molars.


Composite dental fillings are the most widely used method today, thanks to improvements over amalgam materials. With a translucent white color similar to natural teeth, composite fillings make it harder to distinguish from the adjacent teeth.

In addition, composite has a high compatibility and does not harm the teeth or cause negative reactions in the body. However, for large cavities, composite is only suitable as a temporary solution and is not suitable for long-term use. The durability of composite fillings is not high, so if it is used for a large area, it will quickly deteriorate after a short period of time.

Inlay/Onlay Ceramic – the perfect solution for large dental cavities

Inlay/Onlay ceramic fillings are an excellent solution for treating large dental cavities. These fillings are crafted from premium ceramic materials, ensuring good resistance and excellent adhesion.

Unlike conventional dental fillings, Inlay/Onlay ceramics are custom-made in a laboratory based on the actual shape of the tooth.

The durability and adhesion of these fillings are highly evaluated by experts.

Some solutions to limit large cavities

To limit large cavities, you can consider the following solutions:

Prevent the development of tooth decay

To avoid a situation where a cavity becomes large due to lack of timely treatment, pay attention to the symptoms of tooth decay and seek treatment as soon as it is detected.

Proper oral hygiene

Brush your teeth at least twice a day with a soft-bristled toothbrush and use fluoride toothpaste. To effectively remove plaque, you can also use dental floss or a water flosser.

Rinse with saltwater or mouthwash solution

Saltwater has been proven to have effective antibacterial properties and can remove harmful bacteria in the mouth. You can also use mouthwash to clean plaque more effectively.

Regular dental check-ups

Visiting the dentist 1-2 times a year helps protect your oral health comprehensively. Don’t wait until you have a deep cavity to visit the dentist, as the treatment process will be more time-consuming and expensive.

Scaling every 6 months

Plaque will accumulate over time. Brushing your teeth twice a day is not enough to completely remove plaque. Therefore, scaling every 6 months helps remove plaque and maintain oral health.

When you notice signs of tooth decay, visit a dental clinic for early diagnosis and treatment. Don’t let the cavity become too large, as this will make the treatment process more costly and time-consuming.

Therefore, to determine whether filling a deep cavity is feasible or not, visit reputable dental clinics to have the dentist examine and recommend the appropriate method.
