Many people require dental fillings, yet pricing varies widely. Limited knowledge about filling materials often prompts a desire to learn more.
What materials are best for dental fillings?
Amalgam
Amalgam primarily consists of silver, tin, copper, and mercury.As the most commonly used filling material, it offers strength and durability. Widely employed for over a century, it has delivered highly satisfactory results.
Is silver amalgam safe? According to statements from the World Dental Federation and the World Health Organization, dental filling materials—including silver amalgam—rarely cause local side effects or allergic reactions.
Composite Resin
Composite resin closely matches natural tooth color, offering an aesthetically pleasing result, and is therefore most commonly used on front teeth. In appropriate cases, composite resin can also be used to enhance tooth color, shape, and size, beautifying the smile.
The composite resin filling procedure is relatively complex. Composite resin is not as durable as amalgam because it wears down more easily.The primary reason is that after composite resin hardens, it may shrink slightly, creating small gaps between the resin layers. These gaps can cause tooth sensitivity and increase the risk of cavities. Composite resin may also absorb pigments from food and beverages, leading to yellowing over time.It is commonly used for baby teeth, near the gum line, and at the tooth neck. It bonds tightly to the tooth and releases fluoride, helping to strengthen teeth and prevent cavities. Sensitivity after filling is also less common.
Its texture is weaker than composite and amalgam and wears down more easily. Color-wise, it is not as aesthetically pleasing as composite materials.
Nano and Diamond Resin
Nano and diamond resin materials represent the most advanced high-tech filling options available today. They offer superior strength and more natural-looking coloration.
Five Major Risks of Leaving Missing Teeth Unreplaced
Premature Aging
Teeth play a crucial role in maintaining facial appearance, with front teeth significantly impacting facial aesthetics.Front tooth loss can make a person appear less youthful and energetic, accelerating perceived aging. Furthermore, when most or all teeth are missing, the cheeks lose support and sink inward, lips lose fullness, facial wrinkles increase, nasolabial folds deepen, and the corners of the mouth droop, resulting in a noticeably aged appearance.
Gastrointestinal Impact
Tooth loss primarily impairs chewing function, with the severity depending on the location and number of missing teeth.Front tooth loss impairs the ability to bite through food, while back tooth loss hinders thorough grinding. When chewing function declines, inadequately ground or crushed food enters the gastrointestinal tract directly, significantly increasing the digestive system's workload and impairing nutrient absorption. Over time, this may even lead to digestive disorders. Furthermore, complete tooth loss makes it difficult to close the lips tightly, making swallowing food laborious.
Impact on Remaining Teeth
After tooth loss, the chewing burden shifts to the remaining teeth. Simultaneously, the gap created by the missing tooth deprives adjacent teeth of their anchorage and support, substantially increasing the load on these remaining teeth.If left untreated for extended periods, adjacent teeth may tilt, while opposing teeth may elongate. This can subsequently trigger cavities and periodontal disease, further damaging the remaining teeth. When few teeth remain, the excessive biting force they bear leads to rapid alveolar bone loss, causing tooth loosening or even loss.The longer the tooth is missing and the greater the number of missing teeth, the more significant the impact on the remaining teeth.
Impaired Speech
Tooth loss, especially in the front teeth, can cause slurred speech, commonly known as "lisping." Impaired speech can significantly affect a patient's social interactions and may even impact their mental health.
Joint Damage
After tooth loss, reduced chewing function on the affected side may lead patients to develop a habit of chewing only on the opposite side. Additionally, multiple missing teeth or prolonged tooth loss can cause remaining teeth to tilt or elongate, creating occlusal interference and disrupting the bite relationship.These factors can compromise temporomandibular joint stability and lead to joint damage.
