In Which Cases Can Porcelain Veneers Be Applied?
Porcelain veneers can be applied to patients who have teeth that have lost too much material to be met with traditional fillings, patients with wear and fractures in their fillings due to tooth clenching.
How is Porcelain Veneer Applied?
Firstly, the decayed tissue in the area is cleaned. Then, the area where the porcelain filling will be placed is shaped with special burs. After the preparation of the area is completed, an impression is taken.
The porcelain veneer filling prepared in the laboratory is adhered to the tooth with special adhesives.

At the same time, since it is not made directly in the mouth but produced in the laboratory, the contact points with the side teeth are better adjusted.
They have a longer lifespan compared to aesthetic fillings. They have superior features in terms of appearance compared to aesthetic fillings. They are more resistant to high chewing forces than aesthetic fillings.
In which cases should inlay and onlay porcelain be preferred?
It should be preferred in teeth with caries so large that aesthetic fillings are insufficient.
It can also be preferred in cases where aesthetic fillings are broken or constantly falling due to intense tooth clenching.
They may also be suitable for patients who get food between their teeth after aesthetic filling. They increase patient comfort as the contact of the teeth with each other is better provided.
What is the Contribution of Porcelain Filling to Dental Aesthetics?
Porcelain fillings provide excellent aesthetic results in the anterior region of the teeth and smile line by offering opacity and light transmittance very close to the natural structure of the tooth. Thanks to its color matching, it integrates perfectly with the neighboring teeth, so the filled area is almost imperceptible.
In addition, their smooth surface structure reflects light in a similar way to natural teeth, giving a bright and vibrant appearance. These aesthetic advantages increase the self-confidence of the patients and help to preserve the natural smile in the long term.
What is the Difference Between Porcelain Filling and Metal Filling?
These differences will help you choose the most suitable filling type according to your needs and aesthetic expectations after an examination with your dentist.
- Aesthetic Appearance: Porcelain filling perfectly matches your natural tooth color by imitating the light transmittance of tooth enamel. In metal (amalgam) fillings, the gray-black metallic shine is especially noticeable on the front teeth.
- Color Matching and Coloring: Porcelain fillings do not experience color differentiation over time thanks to the possibility of one-to-one shading. Since metal fillings are colorless, they are not ideal for patients with high aesthetic concerns.
- Biocompatibility and Allergy Risk: Porcelain material minimizes the risk of irritation and allergy by working in harmony with the gingival tissue. In metal fillings, allergic reactions to mercury or metals contained in the alloy may occur, although very rarely.
- Thermal Conductivity and Sensitivity: Porcelain fillings reduce hot-cold sensitivity thanks to their low thermal conductivity. Since metal fillings conduct heat quickly, they may cause discomfort when consuming hot or cold food.
- Durability and Longevity: Both types of fillings are long-lasting with proper care; however, the edge fit and hardness of porcelain fillings help keep their lifespan in the 10-15 year range. Metal fillings can last up to 15 years; however, the risk of edge leakage and discoloration increases over time.
- Application and Preparation Process: It is possible to restore the tooth with less material before porcelain filling; it requires precise laboratory work. Metal filling application is usually completed in a single session and there is no laboratory phase.
What is the Effect of Oral Hygiene on Porcelain Filling?
Inadequate oral hygiene can cause microbial plaque to accumulate at the junction between the porcelain filling and the tooth tissue. This can lead to leakage under the filling, increasing the risk of edge caries and gingivitis.
Regular brushing, flossing and, if necessary, maintenance with interfacial brushes will create a healthy fluorine composition around the filling, protecting both the filling and the surrounding gingival tissue. Good hygiene habits prolong the life of the porcelain filling and strengthen the patient’s overall oral health.
How Permanent is Porcelain Filling?
Quality porcelain fillings made with today’s technology can last an average of 10 to 15 years or more with proper oral hygiene, regular dental check-ups and avoidance of hard foods. Porcelain is highly wear-resistant and offers hardness similar to tooth enamel, so it withstands the pressures of daily food chewing over the long term.
The lifespan of the bonding material at the edges of the filling is also protective of the filling, so a yearly check of the quality of the bonding will extend the life of the filling even further. The application technique and the experience of the dentist are also important factors that directly affect the permanence of the porcelain filling.
What Should Be Considered After Porcelain Filling?
After porcelain filling application, it is recommended to protect the filled area from extremely hot or cold food and drinks for the first 24 hours. Items such as stone fruits, nuts or chewing gum should be avoided, as hard and sticky foods can damage the tooth.
Regular gentle brushing with a fluoride-containing toothpaste and flossing will prevent plaque buildup around the edges of the filling and ensure its longevity. In addition, routine six-month dental check-ups are critical to monitor the integrity of the filling and gum health.

In the 2nd session, the porcelain filling produced in the laboratory is adhered to the tooth with special adhesives.
It is not recommended if the loss of material in the tooth is at a level where porcelain filling cannot be made. Post and porcelain veneers are recommended instead of porcelain fillings in teeth with approximately 70% or more material loss.
