Wondering about dental inlays and onlays? These restorative treatments bridge the gap between fillings and crowns, offering a durable solution when tooth damage is too extensive for a standard filling but doesn't require a full crown. At London Dental Specialists, we precisely craft inlays (which fit within the cusps of your tooth) and onlays (which cover one or more cusps) to match your natural tooth structure. Made from strong, tooth-coloured materials, they provide superior longevity compared to traditional fillings while preserving more of your natural tooth. Our patients appreciate how these custom-made restorations strengthen damaged teeth, restore function, and blend seamlessly with their smile. Below are answers to the questions we hear most frequently about these versatile treatments.
What are dental inlays and onlays?
Dental inlays and onlays are conservative restorations used when a tooth has moderate damage but doesn't require a full crown. An inlay fits within the cusps (tips) of the tooth, while an onlay covers one or more cusps. Both are custom-made in a dental laboratory from durable materials like porcelain or composite resin, providing a stronger and longer-lasting solution than traditional fillings while preserving more of your natural tooth structure.
What is the difference between inlays and onlays?
The main difference between inlays and onlays is their coverage area. Inlays fit entirely within the cusps (tips) of your tooth, filling the space between them. Onlays are more extensive restorations that cover one or more of the cusps in addition to the area between them. Your dentist at London Dental Specialists will recommend the appropriate option based on the location and extent of your tooth damage.
How do inlays and onlays differ from crowns?
Inlays and onlays are more conservative than crowns as they preserve more of your natural tooth structure. While inlays and onlays cover only the damaged portion of the tooth, crowns cover the entire tooth above the gum line. Crowns are typically recommended for teeth with extensive damage or decay, whereas inlays and onlays are ideal for moderate damage where sufficient healthy tooth structure remains.
Why might my dentist recommend an inlay or onlay instead of a filling?
Your dentist at London Dental Specialists might recommend an inlay or onlay instead of a filling when:
- The decay or damage is too extensive for a standard filling
- You need a stronger, more durable restoration
- The tooth requires additional structural support
- You want a longer-lasting solution
- The damaged area is in a location that bears significant chewing forces
Inlays and onlays provide superior strength and longevity compared to traditional fillings while preserving more natural tooth structure than crowns.
How long do inlays and onlays last?
With proper care and regular dental check-ups, inlays and onlays can last 15-30 years. Their longevity significantly exceeds that of traditional fillings, which typically need replacement every 5-10 years. To maximise the lifespan of your inlay or onlay, maintain excellent oral hygiene, attend regular dental check-ups at London Dental Specialists, avoid chewing extremely hard foods with the restored tooth, and wear a night guard if you grind your teeth.
What materials are used for inlays and onlays?
Inlays and onlays can be made from several materials, including:
- Porcelain or ceramic - highly aesthetic, matching natural tooth colour
- Composite resin - tooth-coloured and less expensive than porcelain
- Gold - extremely durable and long-lasting
At London Dental Specialists, we'll discuss the most appropriate material for your specific situation, considering factors such as the location of the tooth, aesthetic requirements, and functional needs.
What is the procedure for getting an inlay or onlay?
The inlay or onlay procedure at London Dental Specialists typically involves two appointments:
- First appointment: The dentist removes decay, takes precise impressions of your tooth, places a temporary restoration, and sends the impressions to a dental laboratory.
- Second appointment (1-2 weeks later): The dentist removes the temporary restoration, ensures the custom inlay or onlay fits perfectly, and bonds it permanently to your tooth.
The procedure is comfortable, and local anaesthetic is used to ensure you don't experience pain during treatment.
Are inlays and onlays painful?
The procedure for placing inlays and onlays is not painful. Local anaesthetic is used during the preparation phase to ensure your comfort. After the procedure, you might experience mild sensitivity for a few days, which can be managed with over-the-counter pain relievers if necessary. Unlike crowns, inlays and onlays require less tooth reduction, which typically results in less post-procedure discomfort.
How do I care for my inlay or onlay?
Caring for an inlay or onlay is similar to caring for your natural teeth:
- Brush twice daily with fluoride toothpaste
- Floss daily, paying special attention to the area around the restoration
- Attend regular check-ups and cleanings at London Dental Specialists
- Avoid chewing extremely hard objects like ice or hard sweets
- Consider wearing a night guard if you grind your teeth
With proper care, your inlay or onlay will provide many years of functional and aesthetic service.
