When it comes to restoring damaged or decayed teeth, a plethora of dental treatments are available, including fillings, crowns, inlays, and onlays. While you may have heard about fillings and crowns, dental inlays and onlays are a lesser-known but effective solution for moderate tooth damage. Let’s understand their benefits and how they compare to other treatments so you can make an informed decision about your dental health.
What Are Dental Inlays?
Dental cavities can develop due to various factors, including poor oral hygiene, frequent consumption of sugary or acidic foods, plaque buildup, and tooth wear over time. When enamel weakens and decays, it creates a cavity in the tooth that requires restoration to prevent further damage and sensitivity.
While small cavities can be treated with fillings, larger cavities that compromise a significant portion of the tooth—but not enough to require a full crown—are best restored with dental inlays. These custom-made restorations fit precisely within the cavity and are bonded to the tooth to reinforce its structure while maintaining its natural appearance. Inlays do not cover the cusps (raised edges) of the tooth.
What Are Inlays Made of and How Long Do They Last?
Since inlays are used to fill cavities, they are made from strong, durable materials to provide lasting support and maintain the tooth’s structure. A well-maintained inlay not only restores function and aesthetics but can also significantly extend the lifespan of the treated tooth.
The most common materials used for inlays include:
1. Porcelain: Known for its natural appearance, porcelain inlays blend seamlessly with the tooth. They are stain-resistant and highly durable, making them a popular choice for visible teeth.
2. Composite Resin: A cost-effective alternative that also matches the natural tooth color. However, it may not be as strong or long-lasting as porcelain.
3. Gold: Extremely durable and resistant to wear, gold inlays are ideal for back teeth where chewing forces are strong.
Longevity of Inlays
With proper care, dental inlays can last 10 to 30 years. Their lifespan depends on factors such as:
- Material Choice: Gold inlays tend to last the longest, followed by porcelain and composite resin.
- Oral Hygiene: Regular brushing, flossing, and dental check-ups help prevent decay around the inlay.
- Bite Pressure: Excessive grinding or clenching can wear down or damage an inlay over time.
A well-maintained inlay can provide a long-lasting and effective solution for restoring tooth function and appearance.
What Are Dental Onlays?
While inlays are placed inside the tooth to fill cavities, onlays extend beyond the cavity to cover one or more cusps (raised edges) of the tooth. They provide more coverage than inlays and are used when the damage is more extensive but do not require a full dental crown.
Onlays may be needed when the tooth is damaged due to:
- Decay that extends beyond the chewing surface but doesn’t compromise the entire tooth.
- Fractures or cracks in the cusps that weaken the tooth structure.
- Large cavities where a traditional filling would not provide enough support.
What Are Onlays Made of and How Long Do They Last?
Like inlays, onlays are custom-made from materials such as porcelain, composite resin, or gold and are bonded to the tooth for durability and strength. They help restore the tooth’s function while preserving as much natural tooth structure as possible.
With proper care, onlays can last 10 to 30 years. By maintaining good oral hygiene and scheduling regular dental check-ups, onlays can provide a long-lasting and effective solution for restoring damaged teeth.
How Much Do Dental Inlays and Onlays Cost?
The cost of dental inlays and onlays typically ranges from $650 to $1,200 per tooth.
Several factors influence the price, including:
1. Dentist’s Experience: Highly skilled or specialized dentists may charge more for the procedure.
2. Geographical Location: Dental care costs vary depending on the region and local market rates.
3. Extent of the Procedure: The complexity of the damage and restoration can impact the overall cost.
4. Material Used: Gold tends to be more expensive, while composite resin is generally the most affordable option. Porcelain inlays and onlays cost in between.
Many dental insurance plans typically cover part of the cost, especially if the procedure is medically necessary. Another option for managing expenses is a dental payment plan. Consult your dentist to get an accurate cost estimate and explore payment options that best suit your budget.
What Is the Procedure Like?
The procedure for getting a dental inlay and onlay typically involves two visits. During the first visit, the dentist examines the tooth, removes any decay or damage, and takes an impression to create a custom restoration. The dentist may place a temporary filling to protect the tooth while the dental lab fabricates the inlay or onlay.
During the second visit, the temporary filling is removed, and the dentist checks the fit of the inlay or onlay before permanently bonding it to the tooth with strong dental cement. The dentist then polishes and adjusts the restoration for a comfortable bite. Mild sensitivity may occur initially, but with proper oral hygiene and regular dental check-ups, an inlay or onlay can provide long-lasting durability and function.
How Are Inlays and Onlays Different from Crowns?
While inlays and onlays preserve a significant portion of the natural tooth, crowns cover the entire tooth. Crowns become necessary when the tooth structure is too weak or damaged for an inlay or onlay to provide sufficient support.
Key Differences:
| Feature | Inlays and Onlays | Crowns |
|---|---|---|
| Coverage | Partial (within or over cusps) | Full coverage |
| Purpose | Moderate decay/damage | Severe damage or weak tooth |
| Tooth Preservation | More natural tooth retained | More tooth structure removed |
| Durability | 10-30 years | 10-15 years |
| Cost | $650 to $1,200 per tooth | $800 – $2,500 |
How Are Inlays and Onlays Different from Dental Fillings?
Traditional dental fillings are a quick solution for small cavities, but they may not provide enough strength for larger decay. Inlays and onlays are more durable and custom-made to fit perfectly into the damaged area.
Key Differences:
| Feature | Inlays and Onlays | Fillings |
|---|---|---|
| Coverage | Moderate to large cavities | Small cavities |
| Material | Porcelain, composite resin, gold | Composite resin, amalgam |
| Durability | 10-30 years | 5-10 years |
| Tooth Strength | Reinforces tooth structure | Weaker than inlays/onlays |
| Cost | $650 to $1,200 per tooth | $100 – $500 |
Conclusion
Dental inlays and onlays are the perfect solution for mild to moderate tooth damage. They are not as temporary as dental fillings or too extensive as crowns. They provide the perfect balance of strength, function, and aesthetics while preserving as much natural tooth structure as possible.
