In the world of dentistry, inlays and onlays are increasingly popular restorative solutions. As a supplier of inlays and onlays, I’ve witnessed firsthand the growing demand for these dental products. One question that often comes up is: Do inlays and onlays affect chewing? Let’s delve into this topic to provide a comprehensive understanding. Inlay/Onlay

Understanding Inlays and Onlays
Before discussing their impact on chewing, it’s essential to understand what inlays and onlays are. Inlays are used to fill cavities within the cusps (the raised parts) of a tooth, while onlays are used when the damage extends to one or more cusps. They are custom – made restorations, typically crafted from materials such as porcelain, composite resin, or gold.
These restorations offer several advantages over traditional fillings. They are more durable and can better withstand the forces of chewing. Inlays and onlays are also more aesthetically pleasing, especially when made from porcelain or composite resin, as they can be color – matched to the natural teeth.
How Inlays and Onlays Affect Chewing
Positive Effects
- Restored Functionality: One of the primary benefits of inlays and onlays is that they can restore the natural shape and function of a damaged tooth. When a tooth has a cavity or is otherwise damaged, it can be difficult to chew properly. Inlays and onlays fill the void and provide a smooth surface for biting and chewing. This allows patients to resume normal chewing patterns without discomfort.
For example, if a patient has a large cavity in a molar, the tooth may be weakened and unable to withstand the pressure of chewing. An inlay or onlay can reinforce the tooth, making it stronger and more capable of handling the forces of mastication. - Improved Bite: Inlays and onlays are designed to fit precisely into the tooth. This precise fit helps to improve the overall bite alignment. When the bite is properly aligned, the forces of chewing are evenly distributed across the teeth. This reduces the stress on individual teeth and can prevent further dental problems such as tooth wear, fractures, and temporomandibular joint (TMJ) disorders.
- Long – term Durability: The materials used in inlays and onlays are highly durable. Porcelain, for instance, is resistant to wear and staining, and can last for many years. This means that patients can enjoy normal chewing function for an extended period without having to worry about frequent replacements.
Potential Negative Effects
- Adjustment Period: After getting an inlay or onlay, patients may experience an adjustment period. During this time, they may notice a slight difference in the way their teeth feel when chewing. This is normal, as the mouth needs time to adapt to the new restoration. Some patients may also experience mild sensitivity to hot or cold foods, which usually subsides within a few days to a couple of weeks.
- Malocclusion: In rare cases, if the inlay or onlay is not properly fitted, it can cause malocclusion (an improper bite). This can lead to discomfort while chewing, as well as potential long – term problems such as tooth wear and jaw pain. However, this risk can be minimized by working with a skilled dentist who takes accurate impressions and ensures a proper fit.
Factors Affecting the Impact on Chewing
- Material Selection: The material used for the inlay or onlay can affect its impact on chewing. Porcelain is a popular choice because it is strong, durable, and aesthetically pleasing. It also has a similar hardness to natural teeth, which allows for a smooth chewing experience. Composite resin, on the other hand, is more flexible and can be easily bonded to the tooth. However, it may not be as durable as porcelain and may require more frequent replacement.
- Tooth Location: The location of the tooth receiving the inlay or onlay can also influence its impact on chewing. Molars, for example, are responsible for most of the chewing and grinding of food. An inlay or onlay on a molar needs to be able to withstand high chewing forces. Premolars and incisors, on the other hand, are used more for biting and tearing food, and the restoration may need to be designed differently to accommodate these functions.
- Patient’s Oral Health: The patient’s overall oral health can also play a role in how inlays and onlays affect chewing. If a patient has other dental problems, such as gum disease or tooth decay in other areas of the mouth, it can impact the effectiveness of the restoration. Maintaining good oral hygiene is crucial to ensure the long – term success of inlays and onlays.
Clinical Studies and Evidence
Numerous clinical studies have been conducted to evaluate the impact of inlays and onlays on chewing. These studies have generally shown that inlays and onlays can significantly improve chewing function. For example, a study published in the Journal of Prosthetic Dentistry found that patients who received porcelain inlays reported a significant improvement in their ability to chew food compared to those with traditional fillings.
Another study in the International Journal of Prosthodontics examined the long – term durability of inlays and onlays. The results showed that the majority of inlays and onlays remained intact and functional after several years, indicating their ability to withstand the forces of chewing over time.
Real – life Experiences
I’ve had the opportunity to speak with many dentists and patients about their experiences with inlays and onlays. Dentists often report that patients are generally satisfied with the results of these restorations. Patients appreciate the improved chewing function and the aesthetic benefits.
One patient I spoke with had a large cavity in a molar. After getting an onlay, he was able to chew his food without pain for the first time in months. He also noticed that his bite felt more comfortable and balanced. Another patient who had an inlay on a premolar said that the restoration was barely noticeable and that it didn’t affect her chewing at all.
Conclusion
In conclusion, inlays and onlays can have a significant impact on chewing. In most cases, they offer positive benefits such as restored functionality, improved bite, and long – term durability. While there may be a short adjustment period and a small risk of malocclusion, these issues can be minimized with proper dental care and a skilled dentist.
