When a tooth has too much damage for a standard filling but does not need a full crown, inlays and onlays are the right answer. At Hawkins Dentistry in Marysville, Ohio, Dr. Kent Hawkins uses custom-fabricated inlays and onlays to restore damaged teeth precisely, conservatively, and durably. The results look completely natural, preserve as much of your original tooth as possible, and often last for decades with proper care. We serve patients from Marysville, Dublin, and Plain City, Ohio.
What Are Inlays and Onlays?
Inlays and onlays are indirect restorations — meaning they are custom-made outside the mouth in a dental laboratory and then bonded permanently to the damaged tooth. Unlike a filling, which is placed directly and shaped by hand, an inlay or onlay is fabricated to fit the exact contours of your tooth for a more precise, more durable result.
An inlay fits within the grooves of the tooth, restoring the chewing surface between the cusps. An onlay — sometimes called a partial crown — covers a larger area, extending over one or more cusps of the tooth. Both are made from tooth-colored porcelain, composite resin, or ceramic materials that blend naturally with your smile.
When Do You Need an Inlay or Onlay?
Dr. Kent Hawkins may recommend an inlay or onlay when:
- Tooth decay is too extensive for a filling but not severe enough to warrant a full crown
- An existing filling is cracked, worn, or failing and the underlying tooth needs more support
- A tooth is structurally weakened and at risk of fracturing without added reinforcement
- You want to preserve as much natural tooth structure as possible
Research shows that inlays and onlays can increase tooth strength by as much as 75 percent compared to traditional amalgam fillings — a meaningful advantage for a tooth that has already experienced decay or damage.
Inlays vs. Onlays vs. Fillings vs. Crowns
A filling is the simplest and fastest option for small areas of decay, but it does not reinforce the tooth as effectively as an indirect restoration. An inlay or onlay is more conservative than a crown — it preserves more natural tooth structure — but provides greater strength and durability than a filling for larger areas of damage. A full crown is recommended when decay or damage is too extensive for an inlay or onlay to adequately support the tooth.
Dr. Kent Hawkins will recommend the most appropriate restoration for your specific situation after evaluating the extent of the damage.
The Inlay and Onlay Process
Treatment is completed over two comfortable appointments at Hawkins Dentistry:
- First visit: Dr. Kent Hawkins removes decay and damaged material, shapes the tooth, and takes a precise digital scan or impression. A temporary restoration protects the tooth while your custom inlay or onlay is fabricated in the dental laboratory.
- Second visit: The finished inlay or onlay is bonded to the tooth with strong dental cement, checked for fit and bite, and polished to a natural finish.
Some cases use CAD/CAM technology, which allows same-day fabrication and eliminates the need for a second appointment. Dr. Kent Hawkins will let you know which approach is best for you.
Caring for Your Inlay or Onlay
Inlays and onlays are durable and low-maintenance. Brush twice daily, floss once a day, and keep your regular cleaning appointments at Hawkins Dentistry. Avoid habits like chewing ice or biting hard objects that can damage any restoration. With proper care, inlays and onlays frequently last 10 to 30 years — making them one of the most durable restorations in dentistry.
