Dental filling


The last tooth on the left side of the upper jaw has a cavity.
Can it be filled? Because that's the only tooth with a cavity among all my teeth, I hope to have a complete set of healthy teeth.

Dr. Wang Cunzhen reply Dentistry


Hello Lucien: In principle, if a tooth is salvageable and useful, the primary approach will be treatment.
Even if it cannot be filled, it is recommended to protect it with a crown.
However, if the last tooth is a wisdom tooth, due to the difficulty of maintaining oral hygiene and its limited usefulness, it may be advisable to extract it.

Cavities in your upper left molar can indeed be effectively repaired, and dental professionals have various methods to restore the tooth's structure and function. When you have a cavity, it means that the tooth has undergone decay, which can lead to a hole or cavity in the tooth enamel. This decay is typically caused by a combination of bacteria, sugar, and poor oral hygiene, which leads to the production of acids that erode the tooth structure.

The first step in addressing a cavity is to visit a dentist for an evaluation. The dentist will likely take X-rays to assess the extent of the decay and determine the best course of action. If the cavity is not too deep and has not affected the pulp (the innermost part of the tooth containing nerves and blood vessels), the dentist can usually repair it using a dental filling.
Dental fillings can be made from various materials, including composite resin, amalgam, or gold. Composite resin is a popular choice for molars because it can be color-matched to the natural tooth, making it aesthetically pleasing. Amalgam, which is a mixture of metals, is durable and often used for back teeth due to its strength. Gold fillings are also an option, though they are less common due to their cost.

If the cavity has progressed to the point where it has affected the pulp, a more extensive procedure, such as a root canal, may be necessary. During a root canal, the dentist removes the infected pulp, cleans the inside of the tooth, and seals it to prevent further infection. After a root canal, the tooth is often restored with a crown to provide strength and protection.

In summary, if you have a cavity in your upper left molar, it can typically be repaired effectively, especially if you seek treatment promptly. The key is to maintain good oral hygiene practices, including regular brushing and flossing, and to visit your dentist for routine check-ups. This will help prevent future cavities and ensure that your teeth remain healthy.

In addition to the immediate repair of the cavity, it is essential to consider preventive measures to avoid future dental issues. This includes:
1. Regular Dental Check-ups: Visiting your dentist every six months for cleanings and examinations can help catch cavities early before they become more severe.

2. Fluoride Treatments: Your dentist may recommend fluoride treatments, which can help strengthen tooth enamel and make it more resistant to decay.

3. Dietary Choices: Reducing the intake of sugary foods and drinks can significantly lower your risk of developing cavities. Instead, focus on a balanced diet rich in fruits, vegetables, whole grains, and lean proteins.

4. Proper Oral Hygiene: Brushing your teeth at least twice a day with fluoride toothpaste and flossing daily can help remove plaque and food particles that contribute to tooth decay.

5. Sealants: Dental sealants are a preventive measure that can be applied to the chewing surfaces of molars to protect them from decay.

By taking these steps, you can maintain the health of your teeth and reduce the likelihood of developing cavities in the future. If you have concerns about your dental health or the specific treatment options available for your cavity, don’t hesitate to discuss them with your dentist. They can provide personalized advice and treatment plans tailored to your needs.
