When a tooth suffers from moderate decay, a large fracture, or a failing old filling, a standard composite filling may not provide enough strength to restore it. However, the damage may not be severe enough to warrant grinding down the entire tooth for a full dental crown.
At Bright Whites Dental in Franconia, Alexandria, VA, we offer the perfect middle-ground solution: dental inlays and onlays. Often referred to as “indirect fillings,” these custom-made restorations are crafted from solid, durable materials like porcelain or composite resin. They are designed to fit perfectly into or over the damaged portion of your tooth, restoring its strength, function, and natural appearance while preserving as much of your healthy tooth structure as possible.
Both inlays and onlays serve the same fundamental purpose—to repair a damaged tooth—but they are used depending on the extent and location of the damage.
An inlay is used when the decay or damage is confined within the center of the tooth, specifically within the indentations (the "cusps") on the chewing surface. It is custom-molded to fit perfectly inside these boundaries, much like a puzzle piece.
An onlay is used when the damage is more extensive and extends over one or more of the cusps (the raised points) of the tooth, or covers the entire biting surface. Because they cover more area, onlays are sometimes called "partial crowns."
Choosing an inlay or onlay at Bright Whites Dental offers several significant advantages for your long-term oral health:
Unlike a full crown, which requires reshaping the entire tooth, inlays and onlays only require the removal of the damaged or decayed portion. This conservative approach preserves your natural, healthy enamel.
Because they are custom-crafted in a dental laboratory from high-quality porcelain or composite resin, inlays and onlays are incredibly strong. They can actually increase the structural strength of a weakened tooth by up to 75%.
Indirect restorations are precisely molded to the exact shape of your cavity. This creates a tight, secure seal that prevents bacteria from re-entering the tooth and causing further decay.
Our porcelain inlays and onlays are color-matched to blend seamlessly with your natural teeth. They will not discolor over time like some traditional filling materials.
With proper oral hygiene and regular dental visits, high-quality inlays and onlays can last for decades, often outlasting standard composite fillings.
Getting an inlay or onlay typically requires two visits to our Alexandria, VA office.
For small cavities, a regular composite filling is usually sufficient. However, for larger areas of decay or damage, inlays and onlays are superior. They are stronger, last longer, and provide a better seal against future decay than a very large standard filling, which can weaken the tooth over time.
It depends on the extent of the damage. If a tooth is severely broken or has undergone a root canal, a full crown is usually necessary to protect it. However, if there is still a significant amount of healthy tooth structure remaining, an inlay or onlay is preferred because it is a much more conservative treatment that preserves your natural enamel.
No. We use effective local anesthesia to completely numb the tooth and surrounding area during the preparation phase, so you will not feel any pain. You may experience some mild sensitivity for a few days after the procedure, but this is normal and temporary.
You care for your inlay or onlay exactly as you would your natural teeth. Brush twice a day with fluoride toothpaste, floss daily, and maintain your regular check-ups and cleanings at Bright Whites Dental. Avoid chewing on extremely hard objects like ice or hard candies, which can damage the restoration.
Because they are made from highly durable materials and bonded securely to the tooth, inlays and onlays are very long-lasting. With excellent oral hygiene, they can easily last 10 to 20 years, or even longer.
Most dental insurance plans provide coverage for inlays and onlays, as they are considered necessary restorative treatments (similar to fillings or crowns). Our front office team will gladly verify your specific benefits and provide you with a clear estimate of any out-of-pocket costs before treatment begins.
